Abstract (en)

[origin: US5659316A] PCT No. PCT/CH95/00058 Sec. 371 Date Nov. 15, 1995 Sec. 102(e) Date Nov. 15, 1995 PCT Filed Mar. 16, 1995 PCT Pub. No. WO95/26017 PCT Pub. Date Sep. 28, 1995The motion detector generates a sensor signal (SS) which contains a direct current portion and an alternating current portion. The signal evaluation circuit (3) contains means for filtering out the direct current portion, an analogue-to-digital converter (4) and an amplifier for the alternating current portion of the sensor signal. The analogue-to-digital converter (4) is provided for the direct digitizing of the entire sensor signal (SS) and the means for filtering out the direct current portion are formed by a digital high-pass filter (5) connected downstream of the analogue-to-digital converter.
