IPC: G01M3/20
Filed: 1988-08-23
Granted: 1989-12-07
Abstract: The invention relates to a process for checking the tightness of a test container.

Title: Method and device for digitising an analog signal with an amplitude-dependent resolution
IPC: H03M1/12
Filed: 1988-09-03
Granted: 1990-01-04
Abstract: A device for the amplitude-dependent resolution during digitisation of an analog signal has N analog/digital converters (10) and a combining circuit (17). N reference voltages form the upper limit for the input-voltage ranges. For the respective voltage value of the ith reference voltage it holds true that the voltage difference to the preceding (i-1)th reference voltage is greater by a factor Mi than the voltage difference to the next (i+1)th reference voltage following. An analog input signal (9) is allocated to the input-voltage range in which there is no further reference voltage between its upper limit and the voltage value of the analog input signal (9). The digital output signal (18) digitised in the analog/digital converters (10) and selected in the combining circuit (17) exhibits a very high resolution at small analog input signals (9), which decreases slowly towards large analog input signals (9). Using six 8-bit analog/digital converters, a quasi-13-bit analog/digital converter is constructed which has good resolution even at medium amplitudes. <IMAGE>

Title: Transponder transferring stored measurement data to interrogator - operates without battery using capacitor charged by rectified HF pulses
IPC: G01S13/75
Filed: 1990-02-12
Granted: 1991-04-11
Abstract: The transponder transmits stored measuring data to calling equipment (10) which sends out a HF pulse for data. A resonance circuit is tuned to the frequency of the HF pulse.
