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: Apparatus for measuring the static coefficient of friction (SCOF) of the surface of an operating conveyor belt comprises a friction roller rotatable about an axis perpendicular to the direction of movement of the conveyor belt, a friction roller actuator for moving the friction roller between a retracted disengaged position and an advanced engaged position, and a friction roller drive motor selectively operable, in one instance, for permitting free wheeling rotation of said friction roller when rotatably engaged with the conveyor belt and, in another instance, for rotating said friction roller about the friction roller axis in a direction opposite the direction of movement of the conveyor belt.

Abstract: A dual-board host or main printed wiring structure of a circuit module with increased component mounting area is made plug-compatible with a VME or VME64X backplane to which single-board host or main boards may be attached with connectors of differing dimensions and pin configurations, the center line of which are offset from each other. The connection sides of the two boards are respectively bonded to a heat sink frame structure having a thickness which corresponds to the connector offset on the backplane such that the total thickness of one of the printed wiring boards, the heat sink frame and the two bonding layers with respect to board to connector center line distances equals the connector offset at the backplane.

Abstract: A data processing system and method manages the recognition of text characters in a plurality of document images. The documents are predefined forms having a plurality of fields in which text characters are to be recognized. A form definition data set is used to specify various characteristics of the fields on the form such as their locations. A data capture priority value is specified in the form definition data set for at least some of the fields. This priority is used to manage the workload of the character recognition process. When a large number of document form images have been received by the system, they can limit the backlog volume and maintain a desired throughput for character recognizing the forms by reducing the number of fields which are character recognized on each form. By using the data capture priority value for each field, the character recognition processor can be controlled to omit processing or perform faster, lower-quality processing of low priority fields.
