DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Reference is now made to Fig. 1, which is a simplified illustrative drawing of an integrated imaging system 10 formed on a single integrated circuit chip 12 in accordance with a preferred embodiment of the present invention. Preferably, the integrated imaging system 10 comprises an image sensor 14, such as a 2 dimensional CMOS sensor, such as a sensor commercially available from semiconductor suppliers, such as Tower Semiconductor Ltd., Intel & Hyundai. It is appreciated that the CMOS may also include analog processing functions. In accordance with a preferred embodiment of the present invention, the system 10 also comprises an image processor 16, receiving image data from the image sensor 14. CMOS image processors are commercially available from Texas Instruments under the name of TMS 320Clx and from Motorola, under the name of DSP561xx. The image processor 16 is preferably coupled to an output port 18, which provides a processed image data output from the image processor 16. It is a particular feature of the present invention that the image sensor 14, the image processor 16 and the output port 18 are all embodied on a single integrated circuit chip. In accordance with a preferred embodiment of the present invention, the single integrated circuit chip 12 also preferably comprises a memory 20 for storing at least one of the image data and the processed image data. Additionally in accordance with a preferred embodiment of the present invention, the single integrated circuit chip 12 also preferably comprises a modem 22 coupled to the output port 18 for communicating the processed image data. Examples of CMOS modems are avail- able from Motorola under the name of MC145442 and MC145443. Further in accordance with a preferred embodiment of the present invention there is preferably provided a wireless transmitter 24 for communicating the processed image data, the wireless transmitter 24 being embodied together with the image sensor 14, the image processor 16, the output port 18, and modem 22 on the single integrated circuit chip 12. The image communication apparatus of Fig. 1 may also include a wireless receiver 26, the wireless receiver 26 being embodied together with a modem 22, an input port 27, the image sensor 14, the image processor 16 and the output port 18 on the single integrated circuit chip 12. The receiver 26 is preferably employed to receive control inputs from an external source which govern the operation of the remaining components of the chip 12. Transmitter 24 and receiver 26 may share a single antenna, such as an internal antenna 28 or may employ separate antennas. External antennas (not shown) may be employed with the transmitter 24 or the receiver 26. It is a particular feature of the present invention that incorporation of the entire imaging system on a single chip provides a relatively compact and low cost imaging system which may be employed in applications heretofore unattainable. Reference is now made to Figs. 2A, 2B and 2C, which illustrate the structure and operation of traffic monitoring systems constructed and operative in accordance with a preferred embodiment of the present invention and preferably including integrated imaging systems of the type illustrated in Fig. 1. Fig. 2A illustrates a system wherein static traffic control devices, such as stop signs 100 and traffic lights 102 are provided with imaging systems, preferably of the general type described hereinabove with respect to Fig. 1. As seen in Fig. 2A, an imaging system 104, associated with a stop sign 100 senses when a vehicle passes without stopping and also senses the identity of the vehicle. Similarly an imaging system 106, associated with a traffic light 102, senses when a vehicle passes without stopping for a red light and also senses the identity of the vehicle. The imaging systems 104 and 106 transmit information regarding traffic violations to a control center 108 which provides output indications of the existence and type of a traffic violation and an indication of the identity of the vehicle, typically in the form of a photograph 110 of the vehicle license plate. The traffic monitoring system of Fig. 2A is one example of an image communication system constructed and operative in accordance with a preferred embodiment of the present invention and including an image sensor, incorporated in system 104 or 106, and a transmitter, preferably incorporated in system 104 or 106, functioning as at least part of a node of an wireless audio communications network for communicating image data from the image sensor along the wireless audio communications network. The system preferably also includes an automatic communications actuator operative to automatically operate the transmitter to communicate the image data from the image sensor along the wireless audio communications network in response to occurrence of an event, in this case a traffic violation. Reference is made in this connection to Fig. 8, which is a simplified block diagram illustration of the operation of part of the traffic monitoring systems of Figs. 2A - 2C. It may be seen from a consideration of Fig. 8 that system 104, operating as a stop sign monitor, includes image acquisition circuitry 120, such as image sensor 14 (Fig. 1) as well as dynamic and static image analysis circuits 122 and 124, both of which may be em- bodied in image processor 16 (Fig. 1). The dynamic image analysis circuit 122 typically detects an event by analyzing several images, and thus may detect the failure of a driver to stop at a stop sign. The static image analysis circuit 124, which need not necessarily form part of the stop sign monitor, typically detects the identity of a vehicle committing a traffic offense, such as running a stop sign. The outputs of circuits 122 and 124 are provided to respective event detection and feature extraction circuits 126 and 128, both of which may be embodied in image processor 16 (Fig. 1). The output of event detection circuit 126 may be used as a trigger input to an automatic communications actuator 130 which provides an actuation output to an output port 132, which may be embodied in output port 18 (Fig. 1). Output port 132 typically receives a traffic violation message from a message generator 134, which receives inputs from event detection circuit 126 and feature extraction circuit 128. The traffic violation message is transmitted preferably via a modem 136, which may be embodied in modem 22 (Fig. 1) and an RF transmitter 138, which may be embodied in transmitter 24 (Fig. 1) via a wireless audio communication network 140, of which transmitter 24 is preferably a node thereof. The wireless audio communications network 140 may be a cellular telephone network, a cellular radio network, a pager network, a satellite communication network, any combination of the foregoing or any other suitable type of wireless network. Control center 108 typically comprises an RF receiver 150 which outputs via a modem 142 to message analysis circuitry 152. Outputs of circuitry 152 may be provided to an image display 154 which may be monitored by an operator who may enter data displayed thereon via a data entry port 156 to a control computer 157. Feature processing circuitry 158 receives an output from message analysis circuitry 152. In the case where feature extraction circuitry 128 is not present as part of the stop sign monitoring circuitry 104, such feature extraction circuitry may form part of the feature processing circuitry 158. If feature extraction circuitry 128 is provided as part of the stop sign monitor 104, the extracted feature information transmitted by the stop sign monitoring circuitry may be further processed in circuitry 158. The output of feature processing circuitry 158 is transmitted to control computer 157. The control computer 157 may provide traffic violation reports as desired. Reference is now made to Fig. 9, which is a simplified block diagram illustration of the operation of another part of the traffic monitoring systems of Figs. 2A - 2C. It may be seen from a consideration of Fig. 9 that system 106, operating as a traffic light monitor, includes image acquisition circuitry 220, such as image sensor 14 (Fig. 1) as well as dynamic and static image analysis circuits 222 and 224, both of which may be embodied in image processor 16 (Fig. 1). The dynamic image analysis circuit 222 typically detects an event by analyzing several images, and thus may detect the failure of a driver to stop at a red light. In contrast to system 104 (Fig. 8), system 106 typically comprises an input port 225 which receives an external signal, such as a signal indicating that the traffic light is red. Input port 225 may be an RF receiver or alternatively a receiver port for receiving a red light signal via a wired connection. Alternatively input port 225 may be obviated, in a case where the traffic light is within the field of view of image sensor 14, which has the capability of detecting its status. The static image analysis circuit 224, which need not necessarily form part of the traffic light monitor, typically detects the identity of a vehicle committing a traffic offense, such as running a traffic light. The outputs of circuits 222 and 224 are provided to respective event detection and feature extraction circuits 226 and 228, both of which may be embodied in image processor 16 (Fig. 1). The output of event detection circuit 226 may be used as a trigger input to an automatic communications actuator 230 which provides an actuation output to an output port 232, which may be embodied in output port 18 (Fig. 1). Alternatively, where an input port 225 is provided, the output of input port 225 may provide a trigger input. Output port 232 typically receives a traffic violation message from a message generator 234, which receives inputs from event detection circuit 226 and feature extraction circuit 228. The traffic violation message is transmitted preferably via a modem 236, which may be embodied in modem 22 (Fig. 1) and an RF transmitter 238, which may be embodied in transmitter 24 (Fig. 1) via a wireless audio communication network 240, of which transmitter 24 is preferably a node thereof. The wireless audio communications network 240 may be a cellular telephone network, a cellular radio network, a pager network, a satellite communication network, any combination of the foregoing or any other suitable type of wireless network. Control center 108 typically comprises an RF receiver 250 which outputs via a modem 242 to message analysis circuitry 252. Outputs of circuitry 252 may be provided to an image display 254 which may be monitored by an operator who may enter data displayed thereon via a data entry port 256 to a control computer 257. Feature processing circuitry 258 receives an output from message analysis circuitry 252. In the case where feature extraction circuitry 228 is not present as part of the traffic light monitoring circuitry, such feature extraction circuitry may form part of the feature processing circuitry 258. If feature extraction circuitry 228 is provided as part of the traffic light monitor, the extracted feature information transmitted by the traffic light monitoring circuitry may be further processed in circuitry 258. The output of feature processing circuitry 258 is transmitted to control computer 257. The control computer 257 may provide traffic violation reports as desired. It may be appreciated that Fig. 2A illustrates a situation wherein automatic feature extraction circuitry is either not present or has failed to identify a vehicle. In the embodiment of Fig. 2A, the control center receives an image of the license plate of the vehicle and provides an image output thereof together with a traffic violation report. In the embodiment of Fig. 2B, feature extraction circuitry 128 or 228 is present in systems 104 and/or 106 thus providing an information output of the vehicle license number for transmission to the control center 108. The control center may thus automatically provide an integrated violation report 209 incorporating the vehicle license number, as indicated in Fig. 2B. In the embodiment of Fig. 2C, feature extraction circuitry 128 or 228 is present in systems 104 and/or 106 thus providing an information output of the vehicle license number for transmission to the control center 108. An image of the vehicle license plate is also transmitted to the control center. Here the control center 108 thus automatically provides an integrated violation report 211 incorporating the vehicle license number, and a photograph of the license plate and part of the vehicle. Reference is now made to Fig. 3 which illus- trates the structure and operation of a traffic monitoring system constructed and operative in accordance with another preferred embodiment of the present invention which detects vehicle speed and tailgating and preferably includes integrated imaging systems of the type illustrated in Fig. 1. Fig. 3 illustrates a system wherein traffic monitors 300 containing imaging systems 302, preferably of the general type described hereinabove with respect to Fig. 1 are located along a roadway. As seen in Fig. 3, each imaging system 302 senses the speed of a passing vehicle and also senses the distance between the vehicle and the vehicle ahead of it as well as the identity of each vehicle. The imaging systems 302 transmit information regarding traffic violations to a control center 308 which provides output indications 312 of the existence and type of a traffic violation and an indication of the identity of the vehicle, typically including a photograph 310 of the vehicle license plate. The photograph 310 may form part of an integrated traffic violation report 312. The traffic monitoring system of Fig. 3 is another example of an image communication system constructed and operative in accordance with a preferred embodiment of the present invention and including an image sensor, incorporated in system 302, and a transmitter, also preferably incorporated in system 302, functioning as at least part of a node of a wireless audio communications network for communicating image data from the image sensor along the wireless audio communications network. The system preferably also includes an automatic communications actuator operative to automatically operate the transmitter to communicate the image data from the image sensor along the wireless audio communications network in response to occurrence of an event, in this case a traffic violation. Reference is made in this connection to Fig. 10, which is a simplified block diagram illustration of the operation of part of the traffic monitoring system of Fig. 3. It may be seen from a consideration of Fig. 10 that system 302, operating as a speed and tailgating monitor, includes image acquisition circuitry 320, such as image sensor 14 (Fig. 1 ) as well as dynamic and static image analysis circuits 322 and 324, both of which may be embodied in image processor 16 (Fig. 1). The dynamic image analysis circuit 322 typically detects an event by analyzing several images, and thus may detect vehicle speed. The static image analysis circuit 324, typically detects the distance between a vehicle and the vehicle preceding it as well as the identity of a vehicle committing a traffic offense, such as speeding or tailgating. The outputs of circuits 322 and 324 are provided to event detection circuit 326 and the output of circuit 324 is additionally provided to feature extraction circuit 328, both of which may be embodied in image processor 16 (Fig. 1). Event detection circuit 326 preferably receives both a vehicle speed input and an input indicating the distance between a vehicle and the vehicle preceding it. Inasmuch as tailgating is a function of both vehicle speed and the distance between a vehicle and the vehicle preceding it, circuit 326 employs both inputs to provide an output indication of a tailgating event. The output of event detection circuit 326 may be used as a trigger input to an automatic communications actuator 330 which provides an actuation output to an output port 332, which may be embodied in output port 18 (Fig. 1). Output port 332 typically receives a traffic violation message from a message generator 334, which receives inputs from event detection circuit 326 and feature extraction circuit 328. Alternatively, messages may be stored in a memory at the monitor and transmitted only at predetermined times or in response to received interrogation inputs. This is also true for the embodiment of Figs. 2A - 2C and for all of the other embodiments of the present invention, where appropriate. The traffic violation message is transmitted preferably via a modem 336, which may be embodied in modem 22 (Fig. 1) and an RF transmitter 338, which may be embodied in transmitter 24 (Fig. 1) via a wireless audio communication network 340, of which transmitter 24 is preferably a node thereof. The wireless audio communications network 340 may be a cellular telephone network, a cellular radio network, a pager network, a satellite communication network, any combination of the foregoing or any other suitable type of wireless network. It is appreciated that suitable data compression may be employed in all embodiments of the invention for communication of data over the wireless audio communications network or any other communications network. Control center 308 typically comprises an RF receiver 350 which outputs via a modem 342 to message analysis circuitry 352. Outputs of circuitry 352 may be provided to an image display 354 which may be monitored by an operator who may enter data displayed thereon via a data entry port 356 to a control computer 357. Feature processing circuitry 358 receives an output from message analysis circuitry 352. The extracted feature information transmitted by the speed and tailgating monitoring circuitry may be further processed in circuitry 358. The output of feature processing circuitry 358 is transmitted to control computer 357. The control computer 357 may provide traffic violation reports as desired. It is also appreciated that the apparatus of Fig. 3 may be used for counting vehicles and for providing an output indication of traffic density. Reference is now made to Figs. 4A & 4B which illustrate the structure and operation of a collision monitoring system constructed and operative in accordance with another preferred embodiment of the present invention which detects both the impending occurrence of a collision and the occurrence of the collision and may include integrated imaging systems of the type illustrated in Fig. 1. Figs. 4A & 4B illustrate a system wherein a collision monitor 402 which may include an imaging system, preferably of the general type described hereinabove with respect to Fig. 1, is located within a vehicle. The collision monitor may be a conventional accelerometer sensor which senses sudden deceleration upon impact or any other suitable sensor, such as an optical sensor of the type described in Fig. 1, for sensing the inflation of an air bag upon a collision. It is appreciated that an impact sensor forming part of an air bag actuation system may be employed for this purpose. The collision monitor also preferably includes a location determination device such as a GPS or any other suitable device for enabling the location of the vehicle at the time of the impact to be known and communicated. Alternatively, if a cellular-type location system is employed, the determination of location of the vehicle at the time of the impact is carried out remote from the vehicle. In accordance with a preferred embodiment of the present invention a pre-collision sensor 404 provides a pre-collision warning prior to an expected collision so as to ensure that a collision notification is received, notwithstanding possible disabling of the collision monitor 402 as the result of a collision. It is appreciated that the pre-collision sensor 404 may also be fitted at the rear of the vehicle. The pre-collision sensor 404 typically comprises an optical system which correlates an image of a near object with the speed and direction of the vehicle and which may include integrated imaging systems of the type illustrated in Fig. 1. In this embodiment, the pre- collision monitor 404 preferably includes both an imaging system for sensing proximity of an object and either or both of a speed sensor and an acceleration sensor for determining that a collision with that object is imminent. As shown in Fig. 4A, the pre-collision sensor 404 transmits, via a wireless communications link, information regarding the imminent occurrence of a collision to a central control unit 406. The central control unit 406 awaits either confirmation from the collision monitor 402 that a collision has, in fact, occurred or alternatively a manually actuated signal from a driver that no collision has occurred. In the absence of either indication, the central control unit 406 preferably interrogates the collision monitor 402 as to the collision status of the vehicle. In the absence of an indication of normal vehicle operation or a manually actuated signal from a driver that no collision has occurred, the central control unit 406 treats the occurrence as a collision and proceeds as described hereinbelow. Preferably, as illustrated in Fig. 4B, the collision monitor 402 and the central control unit 406 operate in the following manner when a collision occurs. In response to an impact which exceeds a given threshold, a collision indication as well as information indicating the location of the vehicle at the time of the impact, preferably one which results in air bag inflation, is transmitted via a wireless communication link to the central control unit 406. The central control unit 406 preferably dispatches a mobile assistance unit 408, such as an ambulance, to the scene of the impact. Alternatively, the location of the vehicle at the time of the impact, may be determined directly by the central control unit 406 without the location having been determined by an on-board locator. The collision monitoring system of Figs. 4A & 4B may be another example of an image communication system constructed and operative in accordance with a preferred embodiment of the present invention and including an image sensor, incorporated in system 402 and sensor 404, and a transmitter, also preferably incorporated in system 402 and sensor 404, functioning as at least part of a node of an wireless audio communications network for communicating image data from the image sensor along the wireless audio communications network. The system preferably also includes an automatic communications actuator operative to automatically operate the transmitter to communicate the image data from the image sensor along the wireless audio communications network in response to occurrence of an event, in this case a collision. Reference is made in this connection to Fig. 11, which is a simplified block diagram illustration of the operation of part of the collision monitoring system of Figs. 4A & 4B.

Fig. 6A illustrates a system wherein parking monitors 600, each containing a imaging system 602, preferably of the general type described hereinabove with respect to Fig. 1, are located in suitable propinquity to legal parking spaces sought to be monitored. As seen in Fig. 6A, each imaging system 602 senses whether a vehicle is parked in a given parking space adjacent thereto. The imaging systems 602 transmit information obtained by sensing the presence of a vehicle at a given parking space over a given time duration, either directly or via a local control unit 604, to a control center 608 which provides output indications 653 of whether a given parking space is available. Imaging systems 602 may also transmit information identifying the vehicle which is parked in each space, such as an image of its license plate, or its license number. Billing is effected by the control center 608 based on the information received by it, which identifies the parked vehicle. It is appreciated that the connection between the imaging system 602 and the local control unit 604 may be via a wire connecting system, or via a wireless communication, which may be different to that between the local control 604 and the central control station 608. Fig. 6B illustrates an alternative embodiment of the system of Fig. 6A. In the embodiment of Fig. 6B, payment of parking charges is effected by the driver, preferably in one of the following ways: Via a cellular telephone in connection with an automatic telephone actuated billing center 610; or By inserting money or a debit or charge card or a credit card in a local parking monitor 612 located in the vicinity of the parking location. Preferably, the parking locations are individually designated and the driver indicates the parking location occupied by himself when making payment. This may be obviated when payment is made by the driver via a cellular telephone in a suitably GPS equipped vehicle. In the embodiment of Fig. 6B, individual parking monitors 625 or a regional parking monitor 627, each preferably including an imaging system 602, may be used for enforcement purposes, to note vehicles which are parked without corresponding payment having been made.

Reference is now made to Figs. 7A and 7B, which illustrate the structure and operation of an automated supermarket checkout system constructed and operative in accordance with a preferred embodiment of the present invention and preferably including integrated imaging systems of the type illustrated in Fig. 1. Figs. 7A and 7B illustrate a system wherein shopping carts 700 are each equipped with an imaging system 702, preferably of the general type described hereinabove with respect to Fig. 1, for sensing when an item is placed in the shopping cart 700 or removed from the shopping cart 700. The imaging system 702 preferably is capable of distinguishing between insertion into the shopping cart of a stock item in respect of which payment is required to be made, and other elements which do not require payment, such as the empty hand of a shopper. This distinguishing functionality may employ conventional image processing and recognition functionalities including neural networks or other decision functionalities. In accordance with a preferred embodiment of the invention, a remote evaluation functionality is provided, whereby a decision as to the classification of the element inserted into the cart can be made either by an off-line automatic processor or by a human viewing an image of the element being inserted into the cart. The imaging system 702 additionally may include a price reading functionality, such as a bar code reader. Alternatively or additionally, a separate price reading device 704 may be provided on each cart. As seen in Figs. 7A and 7B, each imaging system 702 senses when an element, such as an item to be paid for, is placed in the shopping cart 700. If the price of the item is read either by imaging system 702 or by a separate price reading device 704, the price is recorded. If, however, an item is placed in the shopping cart without its price having been read, a warning indication is provided. The imaging systems 702 and the price reading devices 704 transmit information obtained by sensing identification codes on products, optionally via a transceiver 706, to a control center 708 which provides an itemized grocery bill 710 and may automatically debit the customer's credit card. Control center 708 may also operate an automatic gate which may permit egress of the customer from the supermarket with his purchases, without further inspection, when no warning indication has been provided and which, in the presence of a warning indication, requires that the shopping cart contents be verified. It is appreciated that in an alternative embodiment of the invention, the control center 708 may be obviated and all of the foregoing functionality may be carried out by circuitry mounted on the cart 700 itself. In accordance with an embodiment of the present invention wherein functionality for distinguishing between insertion into the shopping cart of a stock item in respect of which payment is required to be made, and other elements, such as the empty hand of a shopper is provided, the functionality is actuated by sensing insertion of an element into the shopping cart. Upon insertion of an element, an image of the element being inserted is provided to processing circuitry which may be either mounted on the cart 700 or located at a remote location, such as at the control center 708. The processing circuitry analyzes the image and attempts to clearly distinguish between items to be paid for and other elements. When a determination is made that the element is an item to be paid for, the price reading and warning functionality described above is operated. If a determination is made that the element is clearly not an item to be paid for, the detected element insertion is ignored. If however, the processing circuitry is unable to make a clear determination, a recorded image 718 of the detected element insertion may be provided to a human operator at a remote location, such as at the control center 708, who may view the image 718 and make a suitable determination. This determination may be transmitted back to the shopping cart 700. It is appreciated that the functionality described hereinabove with respect to insertion of elements, including stock items, into a shopping cart may be operated in a similar manner to deal with removal of such elements. The automated supermarket checkout system of Figs. 7A and 7B may be a further example of an image communication system constructed and operative in accordance with a preferred embodiment of the present invention and including an image sensor, incorporated in system 702, and a transmitter, also preferably incorporated in system 702, functioning as at least part of a node of an wireless communications network for communicating image data from the image sensor along the wireless communications network. The system preferably also includes an automatic communications actuator operative to automatically operate the transmitter to communicate the price data along the wireless communications network at a predetermined time, such as every five minutes, in response to placing each item in the cart, or when the customer approaches an exit. Reference is made in this connection to Fig. 14, which is a simplified block diagram illustration of the operation of part of the automated supermarket checkout system of Figs. 7A and 7B. It may be seen from a consideration of Fig. 14 that system 702, operating as an automated supermarket checkout system, includes image acquisition circuitry 720, such as image sensor 14 (Fig. 1) as well as dynamic analysis circuitry 722, which may be embodied in image processor 16 (Fig. 1). The dynamic image analysis circuitry 722 typically determines whether an element is being placed in or removed from the shopping cart in the field of view of the image sensor and whether that element is an item to be paid for. As noted above with reference to Fig. 7B, human intervention may be provided. An event detector 724 receives an output from circuitry 722 and indicates whether item placement or removal is taking place. Static image analysis circuitry 725 may provide an output indication of the price and identification of the product, based on a bar code or other suitable identifier. Circuitry 725 may be unable to provide a clear indication of the identification of the product. In such a case, it may provide an output which causes an image from image acquisition circuitry to be transmitted to control center 708. An automatic communications actuator 730 provides an actuation output to an output port 732, which may be embodied in output port 18 (Fig. 1). Actuator 730 may comprise a clock which causes an item entry or remov- al output to be transmitted with predetermined periodicity. Alternatively, the actuator 730 may be operated in response to each entry or removal of an item from the shopping cart in response to an output indication from event detector 724 or to approach of the shopping cart to an exit. Output port 732 typically receives an item entry or removal message, which may include identification of a item, from a message generator 734, which receives an input from event detector 724 as well as a product identification and price input from circuitry 725. Alternatively, item entry or removal messages may be stored in a memory 735 at the imaging system 702 and transmitted only at predetermined times or in response to received actuation outputs. This is also true for all appropriate embodiments of the invention. The item entry or removal messages are transmitted preferably via a modem 736, which may be embodied in modem 22 (Fig. 1) and a wireless transmitter 738, which may be embodied in transmitter 24 (Fig. 1) via a wireless communication network 740, of which transmitter 24 is preferably a node thereof. Static image analysis circuitry 725 may be unable to provide a clear indication of the identification of the product. In such a case, it may provide an output which causes an image from image acquisition circuitry to be transmitted via the wireless communication network 740 to the control center 708 for further analysis . The wireless communications network 740 may be any suitable type of wireless network. It is appreciated that suitable data compression may be employed in all embodiments of the invention for communication of data over the wireless communications network 740 or any other communications network. Control center 708 typically comprises a wireless receiver 748 which outputs via a modem 750 to message analysis circuitry 752. The analysis circuitry 752 transmits to the control computer 758 which provides a grocery bill 710 and may operate an exit gate 712. In accordance with one embodiment of the present invention, the analysis circuitry 752 may provide an image output to a manned workstation 760, including a display 762, in order to enable an operator to make determinations of whether an element inserted into a shopping cart is an item to be paid for. Inputs provided by the operator are supplied to control computer 758, which may transmit appropriate information in a wireless manner back to a shopping cart. It will be appreciated by persons skilled in the art that the present invention is not limited to what has been particularly shown and described hereinabove.
