Abstract: A football down chain set for monitoring the position of a football. The chain set includes a standard having a pointer attached thereon. The pointer is spaced at a distance from the standard. The pointer gauges a position of the football. Another standard has another pointer attached thereon. The other pointer is spaced at a distance from the other standard, the other pointer gauges a position of the football. A strap interconnects the standard and the other standard. The strap is dimensioned for providing a spacing of ten yards between the pointer and the other pointer.

Abstract: A system and method for acquiring and analyzing the bets at a plurality of locations at a plurality of tables is provided. The system includes a gaming table with a raised platform, underneath which is positioned a video camera for each of the wagering locations on the table. The video cameras on each table are coupled together into a multiplexer, and the multiplexers from the plurality of tables are coupled together and into a central computer. The system and method thus eliminate the labor intensive and often inaccurate technique of tacking the gambling habits of patrons at the gaming tables.

Abstract: A distributed image capture system for industry is provided. The invention includes a system of electronic computer hardware and software that can acquire a video (analog or digital) image of an identification card, voucher chit, receipt, or other desired image at any of a plurality of acquisition stations throughout an establishment. This is done by placing a document or object to be imaged onto video imager at a convenient location. The document or object is acquired, and the image so captured is transmitted along a communications channel to a central computer system, where the image is catalogued with a unique identification number or is defaulted to the date and time of capture.
