Abstract: A racing tracking system and process includes one or more RFID-based tower units connected to a computer. Pairs of tower units may be positioned to provide redundancy of detection so that the front of a participant and the rear of a participant (where bibs may be worn) are detected. The redundancy of RFID-based tower unit detection of front and rear worn bibs assures that all bibs will be read, and improves on the accuracy of a participant's position being confirmed.

Abstract: An improved airport valet communication system is presented. The system attaches a vehicle tag to a vehicle. A stall tag is also provided and is placed somewhere within the vicinity of a parking stall. To communicate with these two tags, a handheld computer is provided by the system for communicating with the vehicle tag via radio frequency communication to obtain an identification of the vehicle and for communicating with the stall tag via radio frequency communication to obtain an identification of the parking stall so as to correlate the vehicle and the parking stall in which the vehicle is parked.
