Body-mounted electronic device system and body-mounted electronic device
First Claim
1. A body-mounted electronic device system comprising:
- a master unit mounted on the bodies having first communication means for executing radio communication with the plurality of child units, first identification data storage means for storing identification data of the plurality of child units, identification data judging means for judging whether the identification data received from the plurality of child units are in agreement with the identification data of child units stored in the first identification data storage means, distance calculation means for calculating distances among the plurality of child units from moving quantity data received from the plurality of child units, and notifying means for notifying the distances among the child units; and
a plurality of child units mounted on the bodies having second communication means for executing radio communication with the master unit, moving quantity-measuring means for measuring the moving quantity corresponding to its own moving distance, and second identification data storage means for storing its own identification data, wherein each of the plurality of child units transmits its own moving quantity data measured by the moving quantity-measuring means together with its own identification data to the master unit through the second communication means, and when the identification data judging means has judged that the identification data received from the plurality of child units are in agreement with the identification data stored in the first identification data storage means, the master unit causes the distance calculation means to calculate the distances among the child units based upon the moving quantity data from the plurality of child units received through the first communication means, and notifies the distances among the child units through the notifying means.

Abstract
A body-mounted electronic device system enabling the user to grasp the conditions of other runners. A master unit and a child unit are mounted on a runner, and a child unit is mounted on another runner. Counting units of the child units count the numbers of steps of the runners at predetermined time intervals, and transmit the data together with their own identification data to the master unit. When the received identification data are in agreement with the identification data stored in an ID setting/storage unit, the reception comparator unit calculates the moving distances of the runners based upon the received step number data, and an among-the-child-units-distance calculation unit calculates the distances among the child units. The distances among the child units that become smaller than a reference distance stored in a preset distance storage unit are notified through a buzzer and a display unit.
