| 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 device comprising a receiver, display, and processor, wherein at least one racer programs the race device with a race group and wears the device during the race; at least one race gate comprising a race gate mat, computer, software and transmitter, wherein each gate transmits information over an effective range; a race course configuration comprising at least one start gate, 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 finish gate, and wherein each race gate is programmed with the appropriate race course configuration for the gate; a participant identification device worn by each registered race participant and encoded to transmit participant information to a race gate mat as the participant crosses the mat; recording, by the race gate computer, a participant time when each participant with a participant identification device crosses a race gate mat; receiving, by the race device when the racer is within the effective range of each race gate, information transmitted from gate transmitter; processing, by the race device processor, the received information, and displaying real-time race information to the racer. |
