    Field of the Invention
    [0001] The present invention generally relates to data capture technology, including barcode scanning technology and RFID technology. History of the Invention
    [0002] Mobile laser beam scanners or laser scanners have long been used to optically read one-dimensional and two-dimensional bar code symbols. The mobile laser beam reader includes a housing, a set of focusing lenses, to focus the laser beam to form a beam point having a certain size in a focal plane over a range of working distance from the housing, a component scan to repeatedly scan the beam on the symbol in a scanning pattern, for example, a line or series of scanning lines passing through the symbol many times per second, a photodetector to detect reflected and / or diffused light from the symbol and converting the detected light into an analog electrical signal, and signal processing circuitry including a digitizer to digitize the analog signal, and a microprocessor to decode the digitized signal, based on a specific symbology used in the symbol. Generally, laser scanners can be operated in a portable and presentation or stationary mode.
    [0003] Solid-state imaging symbols or imaging readers were also used to read the symbols electro-optically. The imaging reader includes a housing, an imager or solid state sensor having an array of cells or photosensors that correspond to image elements or pixels in the imager's field of view, a set of illumination light to illuminate the field of view with illumination light from an illuminating light source, ie laser or one or more light emitting diodes (LEDs), and a set of imaging lenses to capture ambient light or reflected or diffused return lighting from of the imagined symbols over a range of distances. The imager can include a coupled one-dimensional and two-dimensional charge device (CCD) or a complementary metal oxide semiconductor (CMOS), and associated circuits to produce electronic signals corresponding to a one-dimensional and two-dimensional array of pixel information over the field of view. The signal processing circuit includes a microprocessor that processes electronic signals to decode symbols. A directed light generator can also be provided in the housing to project a pattern of directed light onto the symbol prior to imaging. Similar to laser scanners, solid-state imaging scanners can also be operated in a portable or stationary mode.
    [0004] Figure 1 generally represents a 40 barcode optical scanner that can be operated in both portable and stationary modes. The barcode scanner 40 includes a window 46, a trigger 41, a housing 42, and base 48. The electrical power to the electrical components in the barcode scanner 40 can be supplied via cables connected to the housing, or via battery in the housing. The base 48 acts as a support for the barcode 40 optical scanner when placed on a flat surface. The barcode scanner 40 thus can be used as stationary equipment, when placed on a table and the products pass through the window 46. The barcode scanner 40 can also be used as a holding reader, being held by the hands operator, who pulls the trigger 41 to read the bar code.
    [0005] Barcode scanners similar to the optical barcode scanner 40 in Figure 1 have been used widely successfully for a long time in many barcode applications. It is desirable to add another type of data capture capability to these barcode scanners in a modular and economical way. Summary of the Invention
    [0006] In one aspect, the present invention relates to an accessory module for improving a barcode optical scanner. The barcode optical scanner comprises a housing, a base, and an expansion port. The accessory module includes an RFID reader, a body part attachable to the barcode scanner, and an interface connector, to form a communication link, between the RFIDF reader and the barcode scanner when the connector interface is connected to the expansion port of the barcode optical scanner.
    [0007] In another aspect, the present invention relates to a method for improving a barcode optical scanner. The barcode optical scanner comprises a housing, a base, and an expansion port. The method includes: (i) providing an accessory module in an RFID reader, and an interface connector; (ii) coupling the accessory module to the barcode optical scanner to improve the barcode optical scanner; and (iii) connect the interface connector with the expansion port of the optical barcode scanner, to provide the communication link between the RFID reader and the optical barcode scanner.
    [0008] The implementation of the present invention can include one or more of the following advantages: the readability of an RFID reader can be added to an existing barcode scanner in a modular and economically advantageous manner. These and other advantages of the present invention will be apparent to those skilled in the art from a careful reading of the following specification and the study of the various attached figures.

Detailed Description
    [0017] Figure 2 represents a mobile laser beam reader 40 for electro-optically locating a target object, such as symbols encoded according to some configurations. The beam reader 40 includes a scanning mirror 62 in a holding housing 42 having a handle 44 on which a trigger 41 is mounted to initiate the reading. The scanning mirror 62 acts to scan a laser beam from laser 64 in a scanning pattern through a window 46 through the symbol. The reflected light from the symbol is detected by photodiode 66 during the reading. The beam reader also includes a focusing lens assembly or optical system 61 to optically modify the emitted laser beam and digitizer 68 to convert an electrical analog signal generated by detector 66 from the return light to a digital signal to subsequently be decoded with a microprocessor or controller 70 in data indicative of the reading of the symbols. The components mentioned above, except controller 70, are represented in figure 2, as the data capture set 50.
    [0018] Figure 3 represents an imager reader 40 for imagining symbols encoded according to some configurations. Imaging reader 40 includes a one-dimensional and two-dimensional solid-state imager 55 mounted on the loadable and holding housing 42 having a handle 44 that has a trigger 41 to start reading. Imager 55 has an array of image sensors along with a set of imager lens 51 to capture reflected or diffused return light from the symbol through window 46, during imaging to produce an electrical signal indicative of the captured image to be subsequently decoded by controller 70 in data indicative of the symbols read.
    [0019] The imager reader 40 includes an illuminator 52 to illuminate the symbols during imaging with illumination light directed from an illumination light source through the window 46. Thus, the return light can come from an illumination source or from the illuminator itself. environment. The illumination light source comprises one or more light-emitting diodes (LEDs) or laser. A source of directed light illumination 54 may also be provided to emit a beam of directed light and to project or mark a light pattern on the symbol prior to imaging. The components mentioned above, except for controller 70, are represented in figure 3, as the data capture set 50.
    [0020] In the operation of the imager reader 40, the controller 70 sends a command signal to direct the laser / illuminator LEDs 52, typically continuously, or sometimes periodically, during scanning, and energize the imager 55, during the exposure time of a frame, to collect the symbol light for a short period of time, ie 500 microseconds or less. A typical arrangement takes about 33 milliseconds to read the image from the tag, and operates at a frame rate of about 30 frames per second. The array can have about one million image sensors accessible.
    [0021] Also shown in figures 2 to 3, a printed circuit board (PCB) 60 on the handle 44 on which controller 70 and holding battery 72 are mounted. Controller 70 can be mounted on the same PCB as data capture sets 50. Rechargeable battery 72 supplies electrical power to all electrical components in reader 40 in portable mode.
    [0022] Both the barcode scanner in figure 2 and the barcode scanner in figure 3 can be used to read optical symbols, such as one-dimensional and two-dimensional bar codes. In addition to optical symbols, other types of tags (such as RFID tags) are also commonly used for product tracking and identification, and manufacturing, inventory, and distribution control.
    [0023] RFID technology generally comprises interrogating an RFID tag with RF radio frequency waves, and reading RF response waves with an RF reader. An RFID tag typically includes a tiny microchip attached to the RF antenna. RFID tags can be attached to the object to be identified. An RFID reader typically includes an antenna attached to a transmitter and receiver.
    [0024] Figure 4 shows part of an RFID 80 reader simplified in a specific type of implementation. In figure 4, the RFID reader 80 includes an antenna 88 coupled to a transmitter 82 and receiver 84. The RFID reader 80 also includes a circulator 83, a demodulator 86, and a frequency generator 81.
    [0025] In operation, transmitter 82 generates an RF interrogation signal. This RF interrogation signal is coupled to antenna 88 via a three-port circulator 83. The electromagnetic waves radiated from antenna 88 are then received by the antenna on an RFID tag. In response to interrogation from the RFID reader, the RFID tag reflects some electromagnetic waves encoded with identification information from the RFID tag. The electromagnetic response waves are collected by the antenna 88 as an RF response signal. The response RFID signal enters the circulator 83 and is received by the receiver 84. The RF signal received by the receiver, after being amplified, is demodulated with demodulator 86, which receives a reference RF signal from frequency generator 81. The demodulated signals a From the demodulator 86, a signal processing circuit is coupled to decode the demodulated signal from the identification information returned by the RFID tag.
    [0026] In some implementations, demodulator 86 is a double-square demodulator, and demodulated signals from demodulator 86 can be a demodulated vector signal that includes two components: demodulated Irx phase signal and demodulated Qrx quadrature signal . The demodulated vector signal can be coupled to a signal processing circuit for further signal processing.
    [0027] Figure 5 represents an improved optical barcode scanner 40 that includes an expansion port 78, according to some configurations. The barcode scanner 40 includes data capture set 50, microprocessor 70, and battery 72. The data capture set 50 may form part of the barcode scanner in Figure 2 or be part of a scanner. barcode imager in figure 3. In one implementation, as shown in figure 5, expansion port 78 is located in a cavity 49 on the base 48. Cavity 49 of expansion port 78 is covered with cover 47. In some implementations, the lid 47 can be pivoted fully open and in other implementations it can be detached from the base when the expansion port is used to connect other electronic models. In still other implementations, the base 48 does not have the cavity 49 nor the cover 47, and the expansion port 78 can be located in other parts of the base 48, or in other parts of the housing 44.
    [0028] In figure 5 it is also shown that an RFID reader 80 can be connected to the barcode scanner 40 using an expansion port 78. The RFID reader 80 includes an RFID antenna, an RFID transmitter 82, an RFID receiver 84 , and a demodulator 83. The RFID reader 80 also includes an interface connector 89, to form a communication link between the RFID reader 80 and the barcode scanner 40, when interface connector 89 is connected to the port expansion bar 78 of the barcode optical scanner. In some configurations, the RFID reader is also configured to receive electrical power from the battery 72 located in housing 42 of the barcode scanner 40. In other implementations, the RFID reader and barcode scanner 40 are configured to receive electrical power from a cable connected to a wall plug.
    [0029] In figure 5, barcode scanner 40 includes a trigger 41. Trigger 41 is generally used to start reading barcode symbols with barcode scanner 40. When a link communication between RFID reader 80 and barcode scanner 40 is established after interface connector 80 has been connected with expansion port 78, a trigger status 41 can be received by the RFID reader from interface connector 89 Thus, trigger 41 can also be used to start reading RFID 80 tags. While reading RFID tags with the RFID 80 reader can be initiated manually by pressing trigger 41, in other implementations reading RFID tags can also automatically initiated by other trigger events. For example, the reading of RFID tags can be initiated when the presence of the RFID tag is detected by other mechanisms and means. In another example, the reading of RFID tags can be started periodically.
    [0030] In some implementations, the optical barcode scanner 40 of figure 5 can selectively operate either in portable mode or stationary mode. For example, the barcode scanner 40 may include a mode switch (not shown in the figures) for manually selecting the portable or stationary mode. In other examples, the barcode scanner 40 includes an operating mode detector, to detect which mode is intended to be used. Specifically, the barcode optical scanner may include a detection mechanism to detect whether the 40 barcode optical scanner is being held by the operator, or it may include a detection mechanism to detect whether the 40 barcode optical scanner is being held by the operator. it is lifted from the table. In many implementations, the operating mode of the 40 barcode optical scanner can be encoded or identified with the mode status.
    [0031] When a communication link between RFID reader 80 and barcode scanner 40 is established after interface connector 89 has been connected with expansion port 78, the barcode scanner status mode 40 can be received by the RFID reader 80 from interface connector 89. The RFID reader 80 can be configured to adjust the operating mode based on the received mode status of interface connector 89. The RFID reader 80 can be configured to adjust one or more RFID reading parameters based on the received mode status. For example, in stationary mode, RFID power can be adjusted to a low level to ensure that the RFID field of view is limited to the inspection area, as it is undesirable to read other tags, which are not part of the immediate transaction. However, the RFID power can be switched to a higher power to provide interrogation at a greater distance. Other parameters, such as work cycles, for example, can also be adjusted as necessary.
    [0032] As shown in figures 8 and 9, the RFID reader 80 can generally be placed in an accessory module 92 attachable to the base 48 of the barcode 40 optical scanner. Figures 6 to 10 illustrate how accessory module 92 is coupled to the base 48 of the barcode 40 optical scanner, according to some configurations. Figure 6 shows that the base of the barcode optical scanner 40 comprises a cover 47 to cover the expansion port 78 in the base 48. After the cover 47 has been removed, as shown in figure 7, the cavity 49 and the Expansion port 78 is accessible to receive accessory module 92. Then, interface connector 89 of the RFID reader 80 is connected with expansion port 78 of the barcode scanner 40, and accessory module 92 is attached to the base 48 of the 40 barcode optical scanner.
    [0033] In an implementation, as shown in figure 8, accessory module 92 has a form factor that allows accessory module 92 to fit into cavity 49, as in figure 5, located on base 48 of the optical code scanner bar 40. With this form factor, at least a portion of the accessory module 92 can be inserted into the cavity 49 of the barcode 40 optical scanner.
    [0034] In another implementation, as shown in figure 9, accessory module 92 has a form factor that allows a portion of the base 48 to slide into the empty space of accessory module 92. This empty space can be formed along with other parts of the housing for accessory module 92 during the molding process. For example, as shown in figure 10, the void of accessory module 92 for receiving part of the base 48 of the barcode optical scanner 40 is formed by a top cover part 92A and a flat base part 92B. A portion of the base 48 is sandwiched between the top cover part 92A and the flat base part 92B with mechanical fasteners.
    [0035] In addition to the implementation, as in figures 8 and 9, those skilled in the art can recognize that the accessory module 92 can be coupled to the base 48 of the 40 barcode optical scanner through other methods. Furthermore, even if accessory module 92 is coupled to other parts of the barcode scanner 40, a communication link between the RFID reader 80 and the barcode scanner 40 can still be established, when the interface connector 89 of RFID reader 90 is connected to expansion port 78 of barcode scanner 40. The trigger status or mode status of barcode scanner 40 can still be received by RFID reader 80.
    [0036] In the above specification, specific configurations have been described. However, those skilled in the art should appreciate that various modifications and changes may be made to it without departing from its scope, as established by the claims that follow. Therefore, the specification and figures should be taken for illustrative purposes only, and in no way in a restrictive sense, and all modifications are contained in the scope of the teachings taught.
    [0037] The benefits, advantages, solutions to problems, and any elements that cause some benefit, advantage, or solution or become more pronounced, were not constructed as critical, required, or essential aspects or elements of any of the claims or of all of them. The present invention will be defined only by the appended claims including any additions made pending this patent application, and all equivalent to those claims as issued.
    [0038] In addition, throughout this specification, relational terms such as first and second, top and bottom, etc. they can be used to distinguish an entity / action from another entity / action, without necessarily requiring or implying any relationship or order between such entities or actions. The terms "comprises" and "comprising", "has" and "having", "includes" and "including", "contains" and "containing", and their variations, are intended to cover a non-exclusive inclusion, so that a process, method, article, apparatus, which comprises, has, includes, or contains a list of elements, not only includes those elements, but may also include other elements not expressly listed or inherent in such a process, method, article, or apparatus. An element preceded by "comprises ... one", "has ... one", "includes ... one", contains ... one ", does not eliminate, without further restrictions, the existence of additional identical elements in the process , method, article, or apparatus, which comprises, has, includes, or contains the element. Articles “one” and “one” are defined as numerals one or more, unless explicitly stated otherwise. The terms "substantially" "essentially" "approximately", "about" or their variants, are defined as close to the understanding of those skilled in the art and, in a non-limiting configuration, the term is defined as within 10%, in another setting within 5%, and another setting within 1%, and yet another setting within 0.5%. The term “coupled” used in this is defined as connected, although not necessarily directly or mechanically. A device or structure that is configured in one way is configured in at least this way, but it can also be configured in ways not listed.
    [0039] It should be appreciated that some configurations may comprise one or more generic or specific processors (processing devices), such as, for example, microprocessors or digital signal processors, customized processors, programmable field gate arrangement (FGPA), and unique stored instructions (including software and firmware), which control one or more processors to implement certain functions, most functions, or even all functions of the method and / or apparatus described in this processor with certain processor circuits. Alternatively, some or all of the functions could be implemented by a state machine with no stored instructions, or in one or more application-specific integrated circuits (ASICs), in which the functions or combinations of certain functions are implemented as custom logic. Of course, a combination of the two solutions can also be used.
    [0040] Furthermore, a configuration can be implemented as a computer-readable storage medium having computer-readable code stored to execute a program (comprising a processor) to execute the described and claimed method. Examples of computer-readable media include, without limitation, hard disk, CD-ROM, optical storage device, magnetic storage device, ROM (read-only memory), PROM (programmable read-only memory), EPROM (memory only) programmable and erasable read), EEPROM (programmable and electrically erasable read only memory), and Flash memory. In addition, it is expected that those skilled in the art will make a significant effort in various situations motivated, for example, by available time, current technology, and economic considerations, guided by the concepts and principles described in this one, to generate instructions and software programs, and CIs with minimal experimentation.
    [0041] The specification summary is provided to allow the reader to quickly determine the nature of the technical specification, and it is clear that the specification is not intended to interpret or limit the scope or meaning of the claims. In addition, in the section “Detailed Description” it can be seen that several elements and components are grouped together for the purpose of facilitating the understanding of the specification. This method of specification should not be interpreted to reflect the intention that the claimed configurations require more elements than those expressly cited in each claim. On the contrary, as the following claims reflect, the inventive material resides in less than all elements of a single described configuration. Thus, the following claims are incorporated in the “Detailed Description” section, each of which supports its own separately claimed matter.
