A method for efficient operation of a circuit arrangement with a proximity sensor, as well as proximity sensors and circuit arrangements for carrying out this method

摘要

The invention relates to a method for efficient operation of a circuit arrangement with an electronic circuit unit (9) with at least a sleep mode (24), coupled with an interface (6) with a proximity sensor (1) with an electronic evaluation unit (5), which is designed as a master proximity sensor (11), a proximity sensor, which are designed as a slave (12, 13) and at least two gripping areas (2, 2_a, 2_from, 2_s, 2a, 2a_1-2, 2a₁₂, 2a_{P1 - 2}, 2b - d, 2d_1-2, 2d_P2), in the case of which the electronic circuit unit (9) according to configuration of the proximity sensor (1) into an operating mode for the detection of an event in at least one of the sensing regions (2, 2_a, 2_from, 2_s, 2a, 2a_1-2, 2a₁₂, 2a_{P1 - 2}, 2b - d, 2d_1-2, 2d_P2) in one of the sleep modes (24) changes while the electronic evaluation unit (5) in a self-sufficient manner at least two of the sensing regions (2, 2_a, 2_from, 2_s, 2a, 2a_1-2, 2a₁₂, 2a_{P1 - 2}, 2b - d, 2d_1-2, 2d_P2) monitored, in the case of detection of an event in at least one of these areas of coverage of the event that triggers the object to one of two classes and via the interface (6) to terminate the sleep mode (24) at least one of the interrupt (28_{a - b}) , as well as proximity sensors and circuit arrangements for carrying out this method.n="71"
