Title:
機能不全時に電気素子を非活性化する装置及び方法
Document Type and Number:
Japanese Patent JP2009545115
Kind Code:
A
Abstract:
Arrangements (1) are provided with electrical elements (11,21) for, in a feeding mode, receiving feeding signals and, in a non-feeding mode, not receiving the feeding signals, and with circuits (12,22) for, in the feeding mode, detecting malfunctions of the electrical elements (11,21). The circuits (12,22) comprise active switches (13,23) for, in response to detection results, deactivating the electrical elements (11,21) in both modes, in other words in the feeding mode as well as the non-feeding mode. The electrical elements (11,21) for example comprise light emitting diodes, incandescent lights or loudspeakers etc. The active switches (13,23) for example comprise bistable micro-relays or semiconductor switches such as non-volatile power semiconductor switches such as one time programmable flash power MOSFETs etc. Preferably, the arrangements (1) are integrated arrangements.
