    Anti-damage detector and alarm system {ANTI-VANDALISM DETECTOR AND ALARM SYSTEM}
    [2] The direct cost of annual damage is billions of dollars a year in the United States alone. Conventional security techniques such as direct lighting and intruder alerts are often used to prevent vandalism. However, like public transport vehicles, there are many places where this conventional technique is inefficient and impractical. The prior art used to protect glass, plastic windows and public seats is described below.
    [3] i. Glass breakage prevention technology
    [4] A common element of security systems is glass breakage detectors. The old model relies on mechanical disturbances or vibrations. By listening to the glass breaking sound, a new model can be used that uses digital signal processing to protect the entire space. However, the sound frequencies produced by smashing the glass are less or less pronounced. As a result, these new sensors are also vulnerable to various kinds of false alarms, such as music, and must be carefully adjusted to detect all possible glass breaks.
    [5] The windows can be scratched by the use of glass cutting tools, which can be purchased for only a few dollars at hardware stores with intentional vandals. The glass is often damaged. If your original glass is thick enough, has enough thickness, and is not of the automatic safety type, you can get expensive professional services to get rid of these scratches. Much research has been done on films or coatings that can be replaced to restore the scratched plate to its original state.
    [6] ii. Plastic breakage prevention (scratch) detection
    [7] In many cases, various types of glass rather than plates are used, for example plastics such as Lexan. The advantage of plastic plates is that they do not break easily. However, plastic plates are much more susceptible to scratching than glass. Simple keys can also leave deep marks. Scratches are difficult to detect because the sound frequencies involved are much less clear than the sound frequencies associated with glass scratches.
    [8] iii. Seat cut detection
    [9] There is no cost effective system for detecting vandalism such as cuts or cuts on public seats, bus stops and elsewhere on the bus. Perhaps as a result, the sheet is often made of a hard, easy-to-clean, undamaged material such as reinforced plastic.
    [1] FIELD OF THE INVENTION The present invention relates generally to anti-breakage detectors, and more particularly to methods and systems for detecting breakage or damage of materials such as glass and plastics.

    [14] As will be described in detail below, the present invention relates to novel electronic vandalism detectors and systems. Specific targeted signals from these detectors can be provided to existing security systems, or alerted to relevant persons via pagers or other means. Direct intervention is possible before damage occurs, the trend of vandalism can be tracked, and habitual intentional vandals can be easily identified and arrested.

    [30] b. Scratch Detection System for Hard Materials (Glass Plates)
    [31] Figure 2 shows an application of the scratch detection system of the present invention. Exemplary system 11 of the preferred embodiment is intended to detect scratches or cuts of plate or panel 12 of a generally hard surface, such as glass or plastic. The system 11 includes a high frequency microphone sensor device 13 positioned adjacent to the body 12 of the material and preferably attached to the surface of the material by a bonding material such as epoxy. The output of each sensor 13 is connected to a digital signal processing circuit (DSP) 14, the output of which is connected to a reporting system. For example, FIG. 6 shows one suitable reporting system wherein the sensor 13 and digital signal processing circuitry 14 (collectively indicated by reference numeral 16) are connected to a processor, ie a computer 50, This computer is connected to one or more reporting devices (s).

The illustrated system includes a high frequency microphone sensor device 13 positioned adjacent the body of material and preferably attached to the back 22 and / or bottom 23 of the plastic sheet. Each sensor 13 is connected to a digital signal processing circuit 14, which is connected to a reporting system as shown in FIG.
    [34] d. Cut detection system for soft materials (sheets)
    [35] 4 shows an application of the invention to detect damage to soft material. The illustrated application relates to a seat or chair 27. However, the system 26 can be applied to virtually any material where it is desirable to protect the material from the physical damage of the material, such as, for example, cutting or tearing. The illustrated seat 27 comprises a frame of plastic, wood or suitable material having a seat back cushion or insert 28 and a seat cushion or insert 29 of a soft material such as fiber, leather or plastic. The sensing system 26 includes a resistance sensor 33 inserted or formed in the backrest 28 and the seat portion 29. To indicate the mounting of the sensor 33 in the backrest and the seat, the seat 27 appears to have been cut off on its side. The sensor 33 is connected to an associated analysis circuit 34, which is connected to the reporting system as shown in FIG.
    [36] Referring to the drawing of the sheet 27 of FIG. 4 and the schematic view of the sensor conductor arrangement of FIG. 8, in the presently preferred embodiment, the sensor 33 comprises a flexible conductive material 76 which is a composite in sheet form and This conductive material is formed in an array of closely-coupled conductors 77 and is covered with a flexible insulating material 78. The composite 76 is formed or inserted between the cushion 81 and the protected surface layer 79 of fibers, leather, plastics or the like.

Alternatively, the sensor may be a woven metal fiber of the weak layer 79. As shown in Fig. 8 to 10, the sensor is connected to the analog signal analysis circuit 34 through the wiring 32, which is connected to the input of the onboard computer (50), A sudden change in the resistance of the sensor current due to the tearing or cutting of the sheet 27 is monitored.
    [37] A cut or cut detector system is often used, for example: in general public seats; Vehicle seats; Seating in a transportation waiting area (eg, Ray Area Feeding System, California, USA); Commercial and government waiting rooms; And soft materials such as fibers, leather, and plastics can be used in places where damage can occur.
    [38] e. Electronic vandalism detection system for vehicle windows
    [39] 5 shows a vehicle 41, for example a bus, and specifically includes a breakage prevention detector system 40 to protect a glass plate, such as the vehicle window 12, from breakage behavior such as scratching. The high frequency microphone sensor 13 is mounted to the selected window using, for example, an epoxy adhesive. In general, each sensor 13 is connected to the digital signal processing circuit 14 either individually or via a wiring 18 routed by the wiring equipment, as shown in FIG. 6, which is the interface box 49. Is preferably connected to the on-board computer 50, thereby monitoring the output signal generated by the DSP circuit. Referring briefly to FIG. 6, a sensor circuit comprising a digital signal processing circuit 14 associated with the sensor 13 is designated 16. Generally, the DSP 14 is a conventional, inexpensive digital signal processing integrated circuit. The digital signal processing circuit 14 converts the analog frequency into a digital signal in the microphone sensor output signal, which is the natural frequency of the glass caused by scratching the glass. Thus, the microphone sensor and the DSP circuit monitor for scratching of the glass and operate the computer 50 to operate the security system, as described below.
    [40] Vibration caused by scratching glass of hard material is characterized by a distinct and narrow frequency, so that the inherent output signal of the sensor circuit 16 can be easily detected. For example, in a typical window glass, a time and frequency domain plot of typical glass scratches represents a series of pulses, each of which starts at approximately 10 kHz and quickly decays to near zero. The time- and frequency-domain plots when breaking glass are much less pronounced in these cases than the plots associated with glass scratches. The glass scratch frequency spectrum is different from the general automotive vibration, speech, wind or other mechanical vibrations. The distinctive nature of this signal makes it well suited for moving vehicles, and the technology is suitable for use in transport vehicles.
    [41] Unlike detectors that detect signals through the atmosphere, as detailed above, the sensor 13 is preferably mounted directly on the glass to be protected. This is due to the small volume of scratches in the glass. Direct mounting has the advantage of transferring energy directly to the microphone sensor through the vibration of the glass. This method also achieves natural attenuation of air-based noise.
    [42] Referring again to FIG. 6, upon sensing the output signal frequency having distinctive features in the digital signal processing circuit 14, the computer 50 initiates the predetermined operation of the local reporting system 51, whereby one It includes operating the above-mentioned siren, lighting, audio display, image display. The device may be a public device or may involve only administrators, including silent alarms. This could include warning messages only for vehicle operators, such as warning messages on dashboards, control tables, etc. The reporting system may also include recording devices such as cameras, video recorders, and audio recorders, providing a record and evidence of vandalism.
    [43] 5 and 6, the vehicle 41 includes a radio 52, which is connected to and controlled by the computer 50, and connected to the antenna 53, so that the selected information can be sent to a known or remote station 55. To the radio 56). Preferably, the vehicle 41 also includes a receiver 46 to receive, via the antenna 47, the exact location of the vehicle's geographic location from a global positioning system GPS network established by the US government, which is It is generally designated 48 at FIG. 5. Based on the signal generated by the sensor 13, if the computer determines that a breakdown has occurred, the computer automatically operates the local reporting system 51 as described above, and automatically turns on the radio 52. Actuate to send an alarm signal that the base transceiver 56 receives. Generally, the propagated information includes vehicle identification information, geographical location, sensor identification information, and in-vehicle location.
    [44] The base station computer 60 is connected to the radio 56 and includes a resident memory, or a memory that stores information related to the transportation system and a particular vehicle. (NextBus) part of or linked to a vehicle monitoring and information system, which is described in the pending specific application US application no. 08 / 696,811, filed August 13, 96. The NextBus system includes a memory 61 containing a transit data table. It is a table of information about the route schedules and stops of each vehicle in the system, and an information table about the estimated time to reach the next stop based on abnormal and normal conditions affecting the transportation time. The NextBus system also includes a predictive computer 63, which continuously updates the transfer data table, using information regarding normal and abnormal conditions. As shown in FIG. 6, the base computer 60 is connected to the memory 61 and the predictive computer 63 so that a real time and prediction regarding the position of the vehicle in a system including the vehicle 41 is provided. Information can be obtained. From this real time, transport data table, alarm signal from the vehicle 41, the computer 60 can know the identification information and the current location of the vehicle 41, and also known "landmarks" such as the next transport station, intersection, etc. ) ", You can see the expected arrival of the vehicle and the route of the vehicle.
    [45] The base computer 60 is connected to a wired system or a radio wave system 74 and to a police, personnel involved in transport, fixed and portable receivers of the vehicle. Also in a particular example, computer 60 is connected to a paging transmitter 69, which has an antenna 71 for sending information relating to pager 73 carried by security personnel or the like. The pager sends the selected information to these agents, which may include vehicle identification, alert time, type of vandalism (for example, damage to a window), location inside the vehicle, and information useful to block the vehicle in the middle of the vehicle. The degree of usefulness of blocking the vehicle on the way includes possible blocking points such as vehicle route, next intersection and vehicle stop.
    [46] Referring further to FIGS. 5 and 6, in addition to local and remote reporting capabilities, system 40 may include an automatic feedback capability controlled by computer 60, which is selected from the base transceiver Via 56 to the vehicle radio 52. This information includes special instructions such as control signals for operating the appropriate in-vehicle reporting devices, such as driver displays or headsets, status information such as the type of response, predicted blocking points of the vehicle by security personnel, and any suggestive actions to be taken. It includes.
    [47] f. Other microphone sensor application
    [48] As long as the vibration generated by scraping the material to be detectable is sufficiently unusual compared to background noise, the sensing techniques and systems described above can be applied to detect scratches on any material. Examples of suitable materials besides glass include plastic, fiber glass, stainless steel. For example, the spectrum of the time and frequency domain plots of keys that scratch Lexan panels is less pronounced than glass, so in noisy applications such as moving vehicles, the error rate will be higher than the detection of glass scratches. It is expected. In fixed applications, however, the detection should also be appropriate with a simple microphone detector. In addition, higher error rates can be neglected because they are more susceptible to scratches than glass even if the plastic panels or plates are not easily broken.
    [49] In order to detect scratches on windows, sheets, and many other materials or bodies 12 made of transparent or opaque glass, plastic and other suitable surfaces made of hard material, systems 11 (FIG. 2), 21 (FIG. 3), 40 (FIG. 5) can be used by attaching the sensing system sensor to the material or body to be protected and using the system described above. Obviously, the system can be changed, for example by using another reporting device. Each system includes a microphone sensor, a digital signal processing circuit, and one or more reporting devices, which have computer-controlled alarms or indicators to alert in the event of a scratch.
    [50] g. Electronic breakage detection system for vehicle seats
    [51] Referring to Fig. 7, another embodiment of the present invention is shown, which is a damage prevention detection system 44 for protecting a vehicle seat. In FIG. 4, one or more sensors 33 are mounted or integrated in each protected seat 27 of the bus 41, generally connected by wires 32, and in-vehicle computer 50 by each or by wiring devices. ), The output signal generated by the sensor is monitored. Referring to FIG. 6, for simplicity, the sensor circuit including the sensor 33 and the analog signal analysis circuit 34 are designated as 36.
    [52] In general, the computer 50 monitors the signal of the analog analysis circuit 34 to detect a sudden change in sheet sensor resistance. The resistance of the sheet sensor gradually changes over time as the material ages, and this change is well taken into account. Upon detecting the inherent signal change of the tear or cut in the sheet, as described above with respect to FIGS. 5 and 6, the computer 50 starts the operation of the local and remote reporting devices. The computer 50, the reporting device 51, the GPS receiver 46, the radio 52, the base station 55, and other components used in the seat alarm system 44 are used in the window alarm system 40. Is the same as or similar to Also in a vehicle comprising a seat and window alarm system, the system is preferably integrated, and the same computer, reporting device, walkie-talkie, etc. are used in both systems, and the component connections 18, 32 are connected to the same wiring harness or network. You can go through.
    [53] 5 and 6, individual and integrated window and seat alarm systems may include other types of sensors 45, such as for example smoke detectors, which may be integrated into window alarm systems and seat alarm systems. Can be.
    [54] As described above, for quick response in the event of a system alert, a system utilizing the present invention may include a number of different types of alarms, displays, and the like. After the efficiency of this system is known, with a very small percentage of the substantial sensor 13 of FIG. 5 and a lot of inexpensive dummies 43, significant anti-damage effects can be obtained. It may also include a small percentage of the vane sensor 33 in the seat 27 of FIG. 7. The following are examples of certain types of conventional alarms and actuations, which are effective in stopping undesirable cases such as scratches or cuts and preventing or reducing future occurrences.
    [55] 1. Bright lights or sirens can be activated directly.
    [56] 2. Keep silent with alerts You can alert security personnel, who can catch intentional vandals directly. The personnel may in each case carry an alphanumeric handheld pager indicating the type and location of the alert. The employee can then determine the appropriate action.
    [57] 3. The camera is activated and you can shoot the action. Frequent deliberate destroyers and their patterns can be identified and arrested.
    [58] 4. For transport vehicles, the silent indicator can alert the driver and the driver can act directly or indirectly. In transport systems with security cameras, pictures can be stored and sent for action (the habitual criminal can be easily identified and arrested because he will travel a certain route).
    [59] 5. In transport systems with automatic vehicle location and silent alarms, vandalism alarms may sound less severe silent alarms. The actual position of the vehicle, along with the position to go forward, can be transmitted to security personnel. Security personnel can board appropriate vehicles to warn or arrest intentional vandals.
    [60] The present invention has been described in terms of preferred embodiments. However, the present invention is not limited to the described embodiments. Those skilled in the art to which the present invention pertains can understand the described embodiments so that the present invention is generally applicable to breakage prevention sensors for materials having a form of unique breakage, scratching, or the like.
