    BACKGROUND FIELD OF MODALITIES DESCRIBED
    [0001] The modalities described generally refer to portable computing devices such as laptop computers, tablet computers, and the like. More specifically, portable computing device enclosures and methods for assembling portable computing devices are described. DESCRIPTION OF RELATIVE TECHNIQUE
    [0002] In recent years, portable computing devices such as laptops, PDAs, media players, cell phones, etc., have become small, light and powerful. A factor that contributes to this reduction in size can be attributed to the manufacturer's ability to manufacture various components of these devices in increasingly smaller sizes while in most cases increasing the power and or the speed of operation of such components. The smaller, lighter and more powerful trend presents an ongoing design challenge in the design of some components of portable computing devices.
    [0003] A design challenge associated with the portable computing device is the design of the cabinets used to house the various internal components. This design challenge generally arises from a number of conflicting design objectives that include the desire to make the cabinet lighter. and thinner, the desire to make the case stronger and make the case more aesthetically pleasing. Lighter cabinets, which typically use thinner plastic structures and less fasteners, tend to be more flexible and therefore have a greater propensity to warp and bend when used while stronger and more rigid cabinets, which typically they use thicker plastic structures and more fasteners, they tend to be thicker and carry more weight. Unfortunately, however, the increased weight consistent with the more robust cabinet can lead to user dissatisfaction while bending over cabinets formed of light material can result in damage to some of the internal components (such as printed circuit boards) of the portable device.
    [0004] Furthermore, cabinets are mechanical assemblies with multiple parts that are screwed, fixed, riveted, or otherwise attached together at discrete points. These assembly techniques typically complicate the design of the housing and create aesthetic difficulties due to cracks, seams, looseness or undesirable interruptions in the wedding surfaces and fasteners located along the housing surfaces. For example, a wedding line that surrounds the entire cabinet is produced when using an upper and lower case. Furthermore, the various components and complicated processes used to manufacture the portable device can make assembly a time-consuming and clunky process requiring, for example, example, a highly trained assembly operator working with special tools.
    [0005] Another challenge is related to the techniques to assemble the structures inside the portable computing devices. Conventionally, the structures were arranged on one of the boxes (top or bottom) and attached to one of the boxes with fasteners such as screws, fasteners, rivets, etc. That is, the structures are positioned in a way as a layered sandwich on the box and then attached to the box. This methodology suffers from the same disadvantages as mentioned above, that is, the assembly is a long and awkward process.
    [0006] In view of the above, there is a need for improved component density and associated assembly techniques that reduce cost and improve the resulting quality. In addition, there is a need for improvements in the way in which portable devices are mounted such as enhancements that allow structures to be quickly and easily installed inside the case. It is also desirable to minimize the stack height Z of the assembled components in order to reduce the total thickness of the portable computing device and thereby improve the overall appearance and aesthetic touch of the product. SUMMARY OF THE MODALITIES DESCRIBED
    [0007] A portable computing device is described. The portable computing device can take many forms such as a laptop computer, a tablet computer, and so on. In one embodiment, the portable computing device may include at least one one-piece housing that has a front opening. The one-piece housing can, in turn, include integral bottom and side walls that cooperate to form a cavity in cooperation with the front opening. The bottom wall has a curved bottom surface and the side walls can have rectilinear edges arranged so that they form a flat side surface to form a recess within the cavity. In addition, an edge of the side walls surrounds and defines the front opening. An internal surface of the bottom wall includes a plurality of steps suitable for mounting an internal component thereon. The portable computing device also includes a cover arranged inside the front opening and secured in the seamless housing without a frame.
    [0008] In one aspect, the steps can be machined in a configuration using numerical computer controlled machine tools (CNC) and associated techniques. In addition, any sharp edges can be rounded to a more benign shape thereby reducing any chance of damage the internal components.
    [0009] In another embodiment, a system is described. The system includes at least one housing used to support a plurality of internal operating components, a plurality of mounting steps formed on an internal surface of the housing. The plurality of mounting steps is formed by at least removing a pre-selected amount of housing material at predetermined locations on the inner surface. At least some of the mounting steps are used to mount some of the plurality of internal operating components in the housing . An integrated crossbar system can be integrally formed within the housing and be used to provide support for the housing by distributing a force applied at a point within the housing evenly around the housing. The integrated beam system can be formed by removing an amount of housing material that is less than the pre-selected amount used to form the mounting steps at predetermined locations on the inner surface of the housing.
    [00010] In another embodiment, a method for forming a plurality of steps within an enclosure, the enclosure used to support the operational components for a portable computing device is described. The method can be executed by performing at least the following operations. Provide a housing that has an adequate nominal wall thickness to contain and support the operating components of the portable computing device, determine a minimum housing wall thickness, determine a step height that corresponds to each of the plurality of steps, determine a step pattern, and remove an amount of housing material that corresponds to the step height and step pattern.
    [00011] In one aspect, an integrated beam system can be formed by removing less than the determined amounts of material from an internal surface of the housing. The integrated tray system can be part of the housing and can be used to provide support for the housing, in part by distributing a force applied to the portable computing device. In this way, by distributing the applied force, the risk of deforming or damaging the housing can be substantially reduced.
    [00012] In yet another embodiment, a one-piece housing that has a front opening, the one-piece housing in which most of the housing is formed from a radiopaque material is described. In the described embodiment, the one-piece housing includes at least integral bottom and side walls that cooperate to form a cavity in cooperation with a front opening, the bottom wall having a curved bottom surface and the side walls having straight edges arranged in a straight line. so that they form a flat side surface, a recess within the cavity, an edge of the side walls surrounding and defining the front opening, and a cover arranged inside the front opening and secured in the seamless housing without a frame. At least a portion of the housing is removed and replaced with a portion formed of a radiolucent material integrated with the rest of the one-piece housing, the radiolucent portion is in the shape of the portion removed from the housing.
    [00013] A computer-readable medium for tangibly storing a computer program used by a processor to form a plurality of steps within an enclosure is described. In the described embodiment, the enclosure is used to support the operational components for a device of portable computing. The computer-readable medium includes at least one computer code to provide a housing that has a nominal wall thickness suitable for containing and supporting the operating components of the portable computing device, a computer code for determining a minimum housing wall thickness , a computer code to determine a step height that corresponds to each of the plurality of steps, a computer code to determine a step pattern, and a computer code to remove an amount of housing material that corresponds to the step height and the step pattern.

    [00025] In the following document, numerous specific details are presented to provide a complete understanding of the concepts underlying the modalities described. It will be apparent, however, to someone skilled in the art that the modalities described can be practiced without some or all of these specific details. In other cases, well-known process steps have not been described in detail in order to avoid unnecessarily obscuring the underlying concepts.
    [00026] This document discusses an aesthetically pleasing portable computing device to carry with one hand and operate with the other. The portable computing device can be formed from a one-piece seamless housing and an aesthetically pleasing protective top layer that can be formed from any of a number of durable yet strong yet transparent materials such as glass or highly polished plastic. For the remainder of this discussion, however, the protective top layer can take the form of a highly polished cover glass without any loss in general. Furthermore, the uniformity of the appearance of the portable computing device can be improved since (unlike conventional portable computing devices) the cover glass can be mounted in the one-piece seamless housing without the use of a frame. This simplicity of design can result in many advantages for the portable computing device in addition to those related to appearance and aesthetic touch. For example, fewer components and less time and effort may be required to assemble the portable computing device and the absence of seams in the one-piece housing can provide good protection against environmental contamination from internal components. Furthermore, the ability of the portable computing device to successfully withstand the applied loads (such as day-to-day use) as well as those of less frequent but potentially more damaging events such as falling can be substantially improved over computing devices. conventional notebooks.
    [00027] In the described modalities, the one-piece seamless housing can be formed of plastic or metal. In the case where the one-piece seamless housing is formed of metal, the metal can take the form of a single sheet (such as aluminum). The single sheet metal can be formed in a form suitable for housing various internal components as well as providing various openings in which switches, connectors, displays, and so on can be accommodated. The one-piece seamless housing can be forged, molded, or otherwise processed to a desired shape. The shape of the housing can be asymmetrical in that an upper portion of the housing can be formed to have a substantially different shape than that displayed by a lower portion of the housing. For example, the upper portion of the housing may have surfaces that meet at different angles forming a well-defined boundary while the lower portion may be formed to have a surface with a striated shape. The transition zone between the upper portion which has distinct edges and the lower portion, in a striated shape, may take the form of an edge which has a rounded shape which provides both a natural change from the upper portion of the housing (that is, the area of edges) and a smoother surface presented by the lower portion of the housing. It should also be noted that in addition to providing a more aesthetically pleasing transition, the rounded shape of the border in the transition zone can provide a more comfortable touch when being held in a user's hand or during use or merely being carried. One of the advantages of using metal for housing is the metal's ability to provide a good electrical ground for any external components that require a good ground plan. For example, the performance of a built-in RF antenna can be substantially improved when a good ground plan is provided. Furthermore, a good ground plan can be used to help mitigate the deleterious effects caused, for example, by electromagnetic interference (EMI) and / or electrostatic discharge (ESD). However, if an RF antenna is present inside the housing, then at least a portion of the housing (if metallic) is given to a radiotransparent portion.
    [00028] It should be noted that throughout the following discussion, the term "CNC" is used. The abbreviation CNC means computer numerical control and refers specifically to a computer controller that reads computer instructions and drives a machine tool. (a motorized mechanical device typically used to manufacture components by the selective removal of material). It should be noted, however, that any appropriate machining operation can be used to implement the described modes and is not strictly limited to those practices associated with CNC.
    [00029] These and other modalities are discussed below with reference to Figures 1-8. However, those skilled in the art will readily appreciate that the detailed description provided here with respect to these figures is for explanatory purposes only and should not be considered as limiting.
    [00030] Figure 1A illustrates a specific embodiment of the portable computing device 100. More specifically, Figure 1A shows a full top view of the fully assembled portable computing device 100. The portable computing device 100 can process data and more specifically media data such as audio, video, images, etc. As an example, portable computing device 100 can generally correspond to a device that can function as a music player, a game player, a video player, a personal digital assistant (PDA), a tablet computer and / or the like. In reference to being portable, the portable computing device 100 can be held in one hand by a user while being operated by the user's other hand (ie, no reference surface such as a table top is required). For example, the user can hold the portable computing device 100 in one hand and operate the portable computing device 100 with the other hand, for example, by operating a volume switch, a standby switch or providing inputs to a sensitive surface. touch such as a display or sign.
    [00031] The portable computing device 100 may include a seamless one-piece housing 102 that can be formed of any number of materials such as plastic or metal which can be forged, molded, or otherwise processed into a form of - wanted. In these cases where the portable computing device 100 has a metallic housing and incorporates an RF-based functionality, it may be advantageous to provide at least a portion of the housing 102 in the form of radio-transparent (or RF) materials such as ceramic, or plastic. In any case, housing 102 may be configured to contain at least partially any suitable number of internal components associated with portable computing device 100. For example, housing 102 may contain and internally support various structural and electrical components (including integrated circuit and other circuits) to provide computing operations for the portable computing device. Integrated circuits can take the form of chips, chip sets, modules, any of which can be surface mounted to a printed circuit board, or PCB, or other support structure. For example, a main logic board (MLB) can have integrated circuits mounted on it that can include at least one microprocessor, a semiconductor memory (such as FLASH), several support circuits and so on.
    [00032] Housing 102 may include an opening 104 for placing internal components and may be sized to accommodate a set or display system suitable to provide a user with at least one visual content, such as through a display. In some cases, the display system may include a touch-sensitive capability that provides the user with the ability to provide tactile inputs to the portable computing device 100 using touch inputs. The display system can be formed of a number of layers which include a topmost layer being a transparent protective layer 106 formed of polycarbonate or other suitable plastic or highly polished glass. Using highly polished glass, the protective layer 106 can take the form of a cover glass 106 that substantially fills the opening 104. A seal 108 can be used to form a gasket between the cover glass 106 and housing 102. The seal 108 may be formed of a resilient material such as plastic along the lines of thermoplastic urethane or TPU. In this way, the seal 109 can provide protection against environmental contaminants from entering the portable computing device 100. A track 110 can be defined as the uppermost portion of housing 102 surrounding the cover glass layer 106. In order to maintain the desired aesthetic appearance and touch of the portable computing device 100, it is desirable that any displacements between the housing 102 and the cover glass 106 are minimized by the centering track 110.
    [00033] Although not shown, the display panel underlying cover glass 106 can be used to display images using any suitable display technology, such as LCD, LED, OLED, electronics or e-paints, and so on. The display assembly can be placed and secured inside the cavity using a variety of mechanisms. In one embodiment, the display system is fitted within the cavity. This can be placed on the plane with the adjacent portion of the housing. In this way, the display can present visual content that includes video, still images, as well as icons such as a graphical user interface (GUI) that can provide information to the user (for example, text, objects, graphics) as well as receive the inputs provided by the user. In some cases, the displayed icons can be moved by a user to a more convenient location on the display. For example, the GUI can be moved by the user manually by dragging the GUI from a location to a more convenient location. The display can also provide a user with a tactile feedback provided by a number of haptic actuators usually, but not always, arranged in a network of haptic actuators incorporated in the exhibition. In this way, the haptic actuators can provide the user with a tactile feedback.
    [00034] In some embodiments, a display mask (not shown) can be applied to, or incorporated into or under the cover glass 106. The display mask can be used to accentuate an unmasked portion of the display used to present a visual content. The display mask can be used to make a home button 112 less used to provide a specific entry such as changing the display mode, for example, for portable computing device 100. The display mask can make the home button 112 less obvious, for example, being closer in hue or color to the home button 112. For example, if the home button 112 is made of a material that is slightly darker (such as gray or black) than the cover glass 106, so using a similarly colored display mask can reduce the visual impact of the home button 112 when compared to the unmasked portion of the cover glass 106. In this way, the visual impact of the home button 112 can be reduced by being integrated into the overall appearance of the display mask. Furthermore, the display mask can provide a natural mechanism to direct an observer's attention to the unmasked area of the display used to present the visual content.
    [00035] The portable computing device 100 may include a number of mechanical controls to control or otherwise modify certain functions of the portable computing device 100. For example, the power switch 114 can be used to manually turn the device on or off of portable computing 100. A mute button 116 can be used to mute any audio output provided by the portable computing device 100 while a volume switch 118 can be used to increase / decrease the volume of the audio output by the computing device portable 100. It should be noted that each of the input mechanisms described above is typically arranged through an opening in housing 102 so that they can couple with internal components. In some embodiments, the portable computing device 100 may include a camera module configured to provide still images or video. The placement can be varied widely and can include one or more locations including, for example, the front and rear of the device, that is, one through the rear housing, the other through the display window.
    [00036] The portable computing device 100 may include a mechanism for wireless communications, or as a transceiver or receiver type device only, such as a radio, the portable computing device 100 may include an antenna that can be arranged internal to a transparent portion of housing 102. In some embodiments, an antenna may be incorporated into seal 108 or cover glass 106. In other embodiments, a portion of housing 102 may be replaced by a radio-transparent material in the form of a window. antenna described in more detail below. The radiolucent material can include, for example, plastic, ceramic, and so on. Wireless communications can be based on many different wireless protocols including, for example, 3G, 2G, Bluetooth, RF, 802.11, FM, AM, and so on. Any antenna number can be used, which can use a single window or multiple windows depending on the needs of the system. In one embodiment, the system can include at least a first and a second antenna windows embedded in the housing (top and logo).
    [00037] Figure 1B shows a top perspective view of the portable computing device 100 according to the described modalities. As shown in Figure 1B, the portable computing device 100 may include one or more speakers 120 used to make an audible sound. The portable computing device 100 may also include one or more connectors for transferring data and / or power to and from the portable computing device 100. For example, the portable computing device 100 may include multiple data ports, one for each configuration of portrait mode and landscape mode. However, the modality currently described includes a single data port 122 that can be formed from the connector assembly 124 accommodated within an opening formed along a first side of the housing 102. Thus, the portable computing device 100 can use data port 122 for communicating with external devices when portable computing device 100 is mounted on a dock station. It should be noted that in some cases the portable computing device 100 may include an orientation sensor or an accelerometer that can detect the orientation or movement of the portable computing device 100. The sensor may provide an appropriate signal which will then cause the portable computing device 100 presents visual content in an appropriate orientation.
    [00038] The connector assembly 124 can be of any size considered appropriate, such as, for example, a 30-pin connector. In some cases, connector assembly 124 can serve as both a data and power port thereby removing the need for a separate power connector. The connector assembly 124 can be varied widely. In one embodiment, connector assembly 124 may take the form of a peripheral bus connector, such as a USB or FIREWIRE connector. These types of connectors include both power and data functionality, thereby allowing both power supply and data communications to occur between the portable computing device 100 and the host device when the portable computing device 100 is connected to the host device. In some cases, the host device may provide power to the portable media computing device 100 which can be used to operate the portable computing device 100 and / or charge a battery included in this concurrently with the operation.
    [00039] Figures 2A and 2B show an internal view representative of the cavity (also referred to as lumen) 200 of the seamless one-piece housing 102 used to contain various internal components of the portable computing device 100 as shown in Figures 1A and 1B. In the described embodiments, the one-piece seamless housing 102 may be formed of a single sheet of metal (such as aluminum) and formed in an appropriate form using, for example, conventional collapsible core metal forming techniques well known to those skilled in the art. in the technique. Housing 102 may include a number of features used to facilitate the installation of internal components used in the assembly of portable computing device 100. For example, opening 202 may be formed in housing 102 suitably sized and located for an RF antenna. In the case where aperture 202 is used to place an RF antenna, aperture 202 can support an RF antenna support assembly formed of at least some radio-transparent material. In this way, the RF antenna support set can facilitate unimpeded transmission and reception of RF energy in support of any number of wireless protocols such as WiFi, Bluetooth, and so on. It should be noted that the ability to provide unimpeded RF functionality is especially important when housing 102 is formed from radiopaque materials like most metals.
    [00040] In order to accommodate various interfaces (dock, audio connector, volume, power, mute, and so on), openings of various sizes can be created in housing 102. For example, opening 204 can be used to support data port 122, openings 206 can be used to provide support for speakers 120; opening 208 can provide support for volume switch 118 and opening 210 for mute button 116. Furthermore, opening 212 can be used to provide support for power switch 114 and opening 214 for a power connector. audio. It should be noted that any number of proposals can be used to create these openings and make the opening edge appear to be thicker than the thickness (approximately 1.5 mm) of the metal plate used to create the housing 102. The creation of these openings in housing 102, however, can result in long, thin metal webs that may deform from the impact of a fall event or cause housing 102 to exhibit unacceptable flexing under torsion. A specific reinforcement technique is described below.
    [00041] A plurality of steps 216 can be formed on the bottom surface 218 of the housing 102. The steps 216 can be used to provide a support platform for mounting various internal components over the bottom surface 218 of the housing 102. In the embodiment described, steps 216 can be formed by removing a predetermined amount of housing material (such as aluminum) using conventional machining techniques. Typically, each step may have rounded edges in order to protect the internal components that may come into contact. As is apparent from Figures 2A and 2B, steps 216 can also be formed in various patterns, such as pattern 220, 222 and pattern 224. Far from being merely aesthetic in nature, the various patterns can be very useful. For example, the various standards can be used to accommodate the mounting structures used to support internal components, such as, for example, a battery holder. In some cases, pattern 226 may take the form of an integrated beam structure described in more detail below that provides a more uniform distribution of loads applied to housing 102. Furthermore, in addition to providing structural support and helping to resist deformation , the housing material removed in forming the plurality of steps 216 can help to substantially reduce the total weight of the housing 102.
    [00042] Figures 2C and 2D show a cross-sectional view of housing 102 taken along line A-A of Figures 2A and 2B. Specifically, Figure 2C shows the nature of the recessed geometry of housing 102, illustrating more clearly how the linear dimensions (length L, for example) of the opening 104 into which the operating components can be inserted during assembly are smaller than the dimension linear (the length 1 for example) of the housing 102. Furthermore, the curvature of the housing 102 can be asymmetrical in that the upper portion 228 of the housing 102 can be formed to have distinct edges while the lower portion 230 can be formed to have a striated shape. This asymmetry helps in the tactile sensation presented by the portable computing device 100 in part because it provides a better fit for the user's hand.
    [00043] In any case, housing 102 may have a nominal wall thickness tnom (which may be in the order of approximately 1.5 mm). The upper portion 228 can be formed in such a way as to have a substantially uniform average wall thickness close to the nominal tnom wall thickness. As the inner surface 218 of the lower portion 230 substantially conforms to the grooved shape of the outer surface of the housing 102, mounting internal components over the inner surface 218 can be difficult or at most sub-optimal. For example, in order to securely attach an inner component to the inner surface 218, any mounting structure used to mount the inner component to the inner surface 218 would need to be specially machined to mount on the curvature of the inner surface 218. This special machining requires it would create a special tooling and add extra manufacturing costs as well as adding complexity and time required for assembly.
    [00044] Therefore, in order to provide a more properly formed internal surface on which to mount the internal components (as well as to reduce the weight of the housing 102), the internal surface 218 of the housing 102 can be sculpted (using CNC machining techniques , for example) in any appropriate way. The inner surface 218 can be sculpted to include a plurality of mounting steps 216 that can resemble a terrace. First, however, a determination can be made of a minimum thickness min for housing 102 that is consistent with both good structural integrity and a desired weight reduction. For example, in the case where housing 102 is formed of aluminum which has a nominal thickness tnom of approximately 1.5 mm, it has been determined that the minimum thickness tmin of approximately 0.6 mm results in an average step height "h "of approximately 0.5 mm resulting in an average weight reduction of approximately 25%. Using these adjustments, the inner surface 218 of housing 102 can be machined on a machine configured to include a suitable number of steps each having a step height h creating various terrace patterns well suited both to reduce the total weight of the housing and to provide suitable mounting platforms to mount various internal components.
    [00045] As shown in Figure 2E, portions of the inner surface 218 can be maintained at a thickness that is substantially the same as the nominal thickness tnom. For example, in order to distribute any stresses applied in housing 102 more evenly, an integrated beam system 232 (which in Figure 2E resembles the letter "H") can be created simply by not machining these housing portions 102 consistent with the location of the integrated beam system 232. In some cases, however, the integrated beam system 232 can be created by simply removing less material from the housing 102 at those locations that correspond to the integrated beam system 232 so that a thickness t that corresponds to the integrated crossbar system 232 be tnom> t> tmin. In this way, the header structure 232 can distribute the applied loads more evenly across a larger region of the housing 102 thereby minimizing the likelihood of warping or deformation.
    [00046] Unlike the assembly of conventional portable electronic devices where the components are mounted in a top-down mode (that is, the components are inserted into the housing before the frame is fitted). The lowered geometry of the housing 102 requires that all components fit within the dimensions (L, W) of the opening 104. Furthermore, the assembly of the portable electronic device 100 can be performed in a bottom-up mode. In order to facilitate the bottom-up assembly of the portable electronic device 100 and minimize any displacement between the top polished glass layer and a more upper portion of the housing (lane 110), various techniques, devices and systems can be used to minimize stacking tolerance (ie, z-direction).
    [00047] In order to accommodate connector set 124, an opening must be formed in housing 102. In the case where with connector set 124 it has a number of scalable pins (such as 30), the size of the opening required to accommodate connector 124 can be quite large relative to housing 102 thereby adversely affecting the integrity of housing 102. For example, Figure 3 shows a representative opening 300 formed in housing 102 used to accommodate connector assembly 124. In this example, the connector assembly 124 may include a number of connectors arranged longitudinally so that the opening 300 must have a length L1 substantially greater than the width W1 creating a region 302 in housing 102. In the described embodiment, region 302 may have a height h which is substantially less than the nominal height H of the first wall of housing 102 resulting in region 302 having a possibly unsatisfactory resistance p For warping especially in the event of a fall.
    [00048] In order to improve the warping resistance of region 302, a support angle 304 can be used to reinforce region 302 as well as providing a mounting characteristic for connector set 124. In the described mode, the angle bar support bracket 304 may be formed of a strong resilient material such as steel. Support bracket 304 may include lugs 306 used to accept suitable fasteners for attaching connector assembly 124 to support bracket 304. The portion 308 of support bracket 304 may be bent, curved, or otherwise formed along of the fold line 310 which can correspond to the edge 312 formed in a bottom portion of the housing 102. In this way, the portion 308 can be attached directly to the edge 312 using, for example, adhesives along the epoxy lines, or being welded in place. In addition to the fixing portion 308 at the edge 312, the support bracket 304 can be attached to the first wall of the housing 102 using the portion 314. In the embodiment described, the portion 314 can be formed (such as an L shape) in order to provide additional support for region 302 shown below in more detail.
    [00049] Figure 4 shows a representative cross-sectional view 400 of connector assembly 124 and support bracket 304 (specifically regions 308 and 314) according to the described modalities. In order to secure the (L-shaped) region 314 of the support bracket 304 in housing 102 (specifically region 302) an amount 402 of housing material proportional to the size and shape of region 314 can be removed from an internal surface of housing 102 in the area of region 302. An epoxy (or other suitable bonding agent) can then be used to attach region 314 to the newly exposed inner surface of housing 102. Therefore, although an amount of housing material is removed, replacement by region 314 of support bracket 304 substantially increases the strength of region 302.
    [00050] As it is contemplated that the portable computing device 100 can be configured to access wireless networks using any number of wireless protocols, those housing modalities 102 formed of a radiopaque material can be adapted for use with the computing devices RF compliant. For example, in one embodiment, housing 102 may have portions removed in order to reduce the likelihood that the radio opacity of housing 102 will interfere with wireless operations. Consequently, Figure 5 shows a housing 500 formed of radiopaque material such as a metal configured for use with the portable computing device 100 which has a wireless based (RF) functionality. Specifically, housing 500 can be formed similarly to housing 102 with the exception that the radiopaque portion 502 can be removed and replaced with the radiolucent portion 504 (also referred to as an antenna window). In the described embodiment, the antenna window 504 can be formed of plastic, ceramic materials, or any material of adequate strength that has the appropriate level of radio transparency. Therefore, it is contemplated that the antenna window 504 can be placed in the vicinity of an internal RF antenna in order to minimize interference from housing 102 and help to maximize the efficiency of the RF antenna. For both aesthetic reasons and the maintenance of structural integrity of the housing 500, the antenna window 504 can be made to substantially conform to the shape of the housing 500. Therefore, the antenna window 504 can have a shape that conforms to the shape of the housing 500. In this way, the antenna window 504 can have an upper portion that is similar in shape to the upper portion 228 and a lower portion similarly formed to the lower portion 230 of housing 102.
    [00051] In order to ensure easy assembly and good structural adhesion, the antenna window 504 can be formed to include a plurality of grooves 506 arranged to accept a corresponding notch 508 formed on the housing 500. For example, as shown in Figure 6, the antenna window 504 can be placed inside the opening 510 and in a plunge movement, placed in the vicinity of the housing 500 so that the notch 508 can be inserted into a corresponding slot 506. Once each of the notches is inserted into an appropriate slot, an epoxy (or other appropriate adhesive placed inside or inserted into each slot as shown in Figure 7 to permanently attach the antenna window 504 to housing 500. It should be noted that a gap 512 may remain due to differences in coefficients of thermal expansion of housing 500 and antenna window 506.
    [00052] Figure 8 shows a flowchart that describes the process 800 to form a plurality of steps on an internal surface of a housing according to an embodiment of the Invention. The 800 process starts at 802 providing a housing that has a nominal wall thickness suitable for containing and supporting the internal operating components for a portable computing device. In 804, a determination is made of a minimum wall thickness, the minimum wall thickness being at least a wall thickness value consistent with maintaining the total housing integrity. In 806, a step height is determined. In 808, a step pattern is determined. In one embodiment, the step pattern may be that step pattern suitable for mounting a plurality of internal components on a bottom surface of the housing. In another embodiment, the step pattern consistent with an integrated beam structure can be determined. In 810, a predetermined amount of housing material consistent with the determined step pattern is removed from the bottom surface of the housing. In the described embodiment, the predetermined amount of housing material removed results in each of the steps having approximately equal step heights. In some cases, the resulting steps may have edges that are smoothed out in order to reduce the likelihood of damaging the internal components. In the embodiment where an integrated beam structure is formed, then a quantity of material that is less than the predetermined quantity of housing material is removed from portions of the bottom surface of the housing that correspond to the internal beam structure. In some cases, essentially no housing material is removed from the bottom surface of the housing that corresponds to the integrated beam structure, while in other cases, the amount removed is less than the predetermined amount.
