A transponder module of a system for measurement of a race time includes a time base in a microcontroller, which is activated upon receipt of a low-frequency electromagnetic field signal from a transmission antenna of a measuring system which is disposed at the level of a line of passage. The microcontroller, once woken up, is capable of measuring several successive intensities of the captured electromagnetic field in order to reconstruct a curve of the electromagnetic field and to determine a crossing time on the line of passage of the transponder module with the activated time base thereof in order to transmit, to a decoder unit of the measuring system, a signal of the result of the time of crossing determined by the microcontroller.

Transponder module for determination of a crossing time in a measuring system

The method makes it possible to perform the measurement of at least one crossing time of a moving object on a line of passage via a personalized transponder placed on the object. The method includes the steps of:

Method and system for measurement of a crossing time, and transponder module for the system

The invention concerns a method of measuring at least one time or an elapsed period of a competitor in a sports competition via a transponder module which is personal to the competitor and accompanies the competitor throughout the competition in a measuring system. The personalized transponder module is activated at the start of the competition or in intermediate positions or at the finish line of the competition (). Detection of at least one variation in motion or vibration level is effected by a motion sensor () integrated in the transponder module. The transponder module transmits data related to the detection effected by the motion sensor on the competition route or in intermediate positions or at the finish line of the competition, to a decoder unit () of the measuring system to check a time or elapsed period related to the detection of the competitor's motion sensor.

Method of measuring a time in a sports competition using a transponder module, and transponder module for implementing the method

Electromechanical timepiece fitted with a gear train including an hour hand and a minute hand for the current time display on the dial side of the timepiece. The timepiece is arranged to provide at least one additional piece of information relating to a magnitude of time, or to a non-time related piece of information. The timepiece further includes an additional indicator hand arranged to display the additional information, the additional indicator hand being mounted on the back cover side of the timepiece on an arbour of the gear train of the timepiece, so that the additional indicator hand and the hour hand and/or minute hand rotate at the same time and at the same angle, the hour hand and/or the minute hand being driven either to display the current time, or to enable the additional indicator hand to indicate the additional information.
