Title (EN) TESTING THE INTEGRITY OF AN ELECTRICAL CONNECTION TO A DEVICE USING AN ONBOARD CONTROLLABLE SIGNAL SOURCE
(FR) CONTROLE DE L'INTEGRITE D'UNE CONNEXION ELECTRIQUE A UN DISPOSITIF AU MOYEN D'UNE SOURCE DE SIGNAUX REGLABLE INCORPOREE
Abstract:
(EN) An apparatus and method for testing the integrity of an electrical connection (222) to a device (205) using an onboard controllable signal source (300). The onboard controllable signal source provides a test signal output (310) via an electrical signal path (305) without having to directly probe the signal path or the electrical connection. The test signal has a selectable frequency that can be selected to be harmonically unrelated to any other signal from the device. A capacitive sensor (215) positioned over the device (205) and the connector (225) detects the energy of the test signal coupled through the electrical connection. The sensor compares the detected amplitude of the test signal to a threshold value and the outcome of the comparison is indicative of the integrity of the electrical connection.
(FR) L'invention concerne un appareil et un procédé de contrôle de l'intégrité d'une connexion électrique (222) à un dispositif (205), au moyen d'une source de signaux réglable incorporée (300). Cette source de signaux réglable incorporée fournit en sortie un signal d'essai (310), par un trajet du signal électrique (305), sans avoir à contrôler directement ce trajet du signal ou la connexion électrique. La fréquence dudit signal d'essai est réglable, la valeur de cette fréquence étant dépourvue de relation harmonique avec tout autre signal émis par le dispositif. Un capteur capacitif (215), placé sur ce dispositif (205) et sur le connecteur (225), capte l'énergie dudit signal d'essai couplé par l'intermédiaire de ladite connexion électrique. Ce capteur compare ensuite l'amplitude du signal d'essai qu'il a captée à une valeur de seuil, le résultat de cette comparaison indiquant l'intégrité de la connexion électrique.
