Abstract: A portable game and exercise system with electronically-activated targets and a non-contact racquet which is brought into the proximity of the targets as the targets are activated. One or more players sets up a virtual court by positioning a number of targets, and sets up game parameters. Each target contains a radio receiver that allows a controller transmitter to activate it. An active target alerts the player with a visual and/or auditory signal, directing the player to different areas of the virtual court. When a player's racquet is brought within the proximity of the active target within the allotted time, the target designates a hit with a signal. A total score for the game is determined.

Abstract: An efficient method and apparatus for livestock data collection and management is described to provide quality assurance source verification data and performance tracking for individual animals throughout the production cycle. Individual animal data is efficiently collected, transferred, and shared in a transactional, event-oriented, row-oriented structure with few columns without need for creating relational structures. The BeefLink™ software includes components for data collection and real-time data lookup components; share, switch, route, and interface components; extract, transform, and load components; and report and analyze data components. Embodiments include data acquisition from multiple RFID reader locations; a web-based information system for a beef marketing alliance; value-based procurement, and supply chain management.
