Abstract
L'appareil de chronométrage décrit fournit des informations de chronométrage à une personne se déplaçant (11) qui franchit une ligne de référence (13). Une source de radiation (15) située sur la ligne de référence (13) émet une radiation modulée dans une zone de radiation conique divergente (16) en travers d'une trajectoire (12), sur laquelle se déplace la personne, cette zone s'étendant de part et d'autre de la ligne de référence (13) en travers de la voie (12). Un capteur de radiation (21) disposé sur une antenne (22) reçoit la radiation émise par la source de radiation (15), au moment où la zone de radiation (16) est traversée, et génère un signal de capteur (21a). Un circuit détecteur de radiation (26) reçoit le signal de capteur (21a) et est réglé de façon à distinguer la radiation modulée provenant de la source de radiation (15) et de façon à générer un signal de détecteur (26a) tant que la radiation provenant de la source de radiation (15) est reçue et détectée. Un circuit calculateur (27) calcule une proportion prédéterminée de la durée de traversée de la zone de radiation, représentée par la durée du signal de détecteur (26a), afin de déterminer l'instant de franchissement de la ligne de référence (13), et un organe d'affichage (28) affiche les informations de chronométrage désirées, telles que le moment du franchissement de la ligne de référence (13).The described timing apparatus provides timing information to a moving person (11) crossing a reference line (13). A radiation source (15) located on the reference line (13) emits modulated radiation in a divergent conical radiation area (16) across a path (12), over which the person moves, this area s 'extending on either side of the reference line (13) across the track (12). A radiation sensor (21) disposed on an antenna (22) receives the radiation emitted by the radiation source (15), as the radiation area (16) is passed through, and generates a sensor signal (21a). A radiation detector circuit (26) receives the sensor signal (21a) and is adjusted to distinguish the modulated radiation from the radiation source (15) and to generate a detector signal (26a) as long as the radiation from the radiation source (15) is received and detected. A calculating circuit (27) calculates a predetermined proportion of the duration of the crossing of the radiation zone, represented by the duration of the detector signal (26a), in order to determine the instant of crossing of the reference line (13), and a display member (28) displays the desired timing information, such as when the reference line is crossed (13).
