| 摘要 |
The invention comprises systems and devices for calculating and displaying real-time race information to a racer during a race. A portable race device may be worn by a racer. During the race, while within range of a race gate transmission, the race device receives gate crossing times for other race participants, and may calculate and display the current positions and times for a selected race group, and the pace needed for the racer to win, and also may display the projected finish positions and times for a selected race group, and the pace needed for the racer to win. |

1. A system for providing real-time race information to at least one racer in a race comprising:
a race comprising a race course, race gates, one racer with a race device, and a plurality of race participants each with a participant identification device, wherein the racer with the race device and the race participants are competing concurrently in the same race, on the same race course, crossing the same race gates; the race device comprising a receiver, display, and processor, wherein the racer programs the race device with a race group, and wears the device during the race, and wherein the race group comprises a plurality of race participants; the race gate comprising a race gate mat, computer, software, and transmitter, wherein each gate transmits gate information over an effective range; the race course configuration comprising one start gate, at least one mid-course gate, and finish gate, the location of each race gate, the number of times each race gate will be visited, and the distance from the gate to the race finish, and wherein each race gate is programmed with the appropriate race course configuration for the gate; the participant identification device worn by registered race participants, and encoded to transmit participant information to each race gate as the participant crosses each race gate; recording, by the race gate computer, a unique participant time linked to each participant when each participant with a participant identification device crosses each race gate; transmitting, by each race gate transmitter, gate information wherein the gate information transmitted comprises participant identification information and linked unique participant time, race course configuration, and wherein said information is transmitted over an effective range; receiving, by the race device when the racer with the race device is within the effective range of each race gate, gate information transmitted from each gate transmitter; processing, by the race device processor, the received information, and displaying real-time race information to the racer with the race device while the racer is on the race course and in time to affect the outcome of the race. |
