UHF timing system for participatory athletic events
First Claim
1. A method of collecting information from participants in a participative athletic event, the method comprising:
- receiving information from a plurality of wireless data tags using one or more antennas adapted for use in the participatory athletic event and capable of radiating at UHF frequencies for communications with the plurality of wireless data tags that are tuned to such frequencies, and suitably designed so as to provide uniformly distributed radiated energy along a participant'"'"'s path of travel in a participatory athletic event and to provide sharp drop offs in radiated energy perpendicular to said participant'"'"'s path of travel for minimizing interference with other adjacently positioned antennas among said one or more antennas, wherein said one or more antennas include casing material that extends in a width of field direction perpendicular to said participant'"'"'s path of travel ending where radiated energy drops off so that casing material of adjacently positioned antennas may be positioned end to end without spaces therebetween; and
determining participant bib numbers corresponding to respective wireless data tags among said plurality of wireless data tags using only said information received from said plurality of wireless data tags or mathematical calculations therefrom.

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. Antennas suitably designed and adapted for use with the data tags in participative athletic events are used to communicate with the data tags.
