Abstract: In a video conferencing system, digital data representing pixels of a selected scene are stored in a Video accumulator Array Memory cells (VAM), each cell having memory with several register structures and having the capability of processing the digital data to facilitate compression of the digital data. The VAM has the ability to tell the processor information about the temporal nature of the video data without requiring the processor to first read the data and then test the data. In accordance with the present invention, the capability of processing the video data is designed directly in the memory function as they are stored. The memory array, by providing a capacity of temporal processing wherein the digital data in one video frame can be logically interacted with another video frame later in time, can make a significant reduction in the bandwidth required to transmit a video frame.

Abstract: A purchasing aid logistics appliance that assists a purchaser with a shopping list generation, in-store product location, automated checkout, and financial management. The PAL is in the form of a battery operated PAL with touch screen display and multimedia input/output. The PAL functions as a fiduciary aid and two-way communications device secure for managing money and processing perishable data. The PAL can function as a stand-alone device or synchronized with a user's personal computer via a RF or IR 1ink.

Abstract: A Vehicle Information and Safety System (VISC) includes a main computer at a vehicle fleet headquarters (HQ) with access over a CDPD data network to a computerized sensor system mounted in each vehicle of the fleet. Sensors which may be used include load sensors coupled to the axles, accelerometers and temperature sensors coupled to the cargo bay, infrared andor pressure sensors monitoring the operator, cameras viewing the cargo bay, cab andor environment, and GPS data. The sensor data are processed by in-vehicle andor HQ computers, to monitor the state of the vehicle and operator, and the security status of the vehicle. PSAP (911) calls can be transmitted from the vehicle under remote control from the HQ for those cases in which the operator is unavailable or unresponsive, and the transmission can be tagged with GPS data. Speech signals from the operator are converted to text, and may be used for control of various functions, or may be data-compressed for transmission over the data network to HQ.

Abstract: A video decoder for receiving compressed, weighted, and encoded input video data in matrix form. The video data is produced from the original difference vector of each pel and transmitted as a bitstream including compressed pel data word descriptor. The video decoder reconstitutes the bitstream into matrix format and calculates individual pel values. The decoder includes capability for restoring the original modulo of the pel data word descriptor and restoring the associated address of each pel in the matrix.
