Abstract: A system for tracking competitors conducting a race on a track includes multiple object-recognition devices positioned to recognize objects at predetermined locations along the track. The object-recognition devices are configured to recognize at least one physical feature of each of the competitors. A processing device is configured to determine a time at which a competitor reached a selected one of the predetermined locations during the race based on object-recognition data from at least one of the object-recognition devices. A transmitter is configured to transmit to an output device the time at which the competitor reached the selected location during the race.

Abstract: A disposable race bib timing device is provided including a thin, flexible planar sheet member having a front surface for displaying information, and a rear surface. An RFID timing tag is provided on the rear surface of the flexible planar bib. A thermal and moisture resistant layer of material is provided over the exposed outer surface the RFID tag to prevent moisture and heat from the athlete from coming into contact with the RFID tag and interfering with the ability of the tag to communicate with the antenna of a corresponding timing system. A further waterproof layer of material may be positioned between the RFID tag and the race bib to prevent moisture from soaking through the bib into the RFID tag. A laminate material may be provided to cover the entire surface.

Abstract: An embodiment of the present invention is a technique for timing participants in sporting events with RFID tags. RFID tags have read and writable memory that is loaded with race numbers or an encoding of it. RFID tags are distributed to participants by attaching them to race bibs that display the race numbers. RFID tags may be left on the race bibs, or removed from the bibs and attached to shoes, clothing, or other apparatus used in the race. A plurality of RFID tags may be used by each participant for pre-race, during race and post-race tracking and locating applications. This invention also includes methods for constructing RFID enabled race bibs.

Abstract: A participatory athletic event timing system based on backscattering modulation in the UHF band and including wirelessly encoding writable data tags with participant's bib numbers or a calculated derivative thereof for timing participants in a participative athletic event, and attaching the data tags to the participant's bibs for distribution of the bibs and data tags to participants so as to eliminate the need for matching data tags with bibs and maintaining the sequenced order of the matched data tags and bibs. In a preferred embodiment, when participants register for the event, they are assigned an ID number and a bib printed with that number and having attached to the bib one or more data tag encoded in the tags memory the ID number or a calculated derivative thereof. Before the start of the event, the athlete pulls the data tag from the bib and attaches it to their shoe.
