摘要:
A comparison circuit (1), obtained according to MOS technology, for comparing two input voltages and comprising a differential amplifier (8). During a first time period, a first input (-) of the differential amplifier is supplied, via a first capacitor (9) and a switch (10), with a first input voltage (Ue). During a second time period, succeeding the first time period, a second input voltage (Ud) is supplied to the first input (-) of the amplifier by means of the first capacitor and a switch (11) of a switch arrangement (10, 11). The second input (+) of the differential amplifier is connected to a reference voltage during the first time period and its output is at that time connected to the first input and to the second input (+) of the amplifier via switches (12) and (16), respectively. The second input (+) of the differential amplifier is connected through a second capacitor (13) and a change-over device (14, 15) to the reference voltage source (17). The change-over device (14, 15) alternately connects, during the two time periods, the second capacitor to the reference voltage source.
摘要:

摘要:
A method and a device for controlling operational sequences, particularly in a vehicle, at least one sensor having a connection unit being connected via a bus system to at least one control unit for controlling the operational sequences, the control unit likewise having a connection unit, and sensor information being transmitted to the control unit, the control unit reading in and/or processing the sensor information at specifiable synchronization points, the synchronization points being ascertained independently of one another in the control unit and in the sensor by, in each case, a synchronization element in such a way with an allowance that the sensor information is available at the synchronization point for the control unit in a manner that it is able to be read in and/or processed.
摘要:
In a device for treating blood in an extracorporeal circuit, at least one blood pump and at least one filtering device are provided for carrying out the blood treatment. The device includes at least one pressure-measuring element for detecting the blood pressure, which is characterized in that the pressure-measuring element has a sensor unit and an RFID transponder unit.

摘要:
A device for measuring a motion of a vehicle includes an acceleration sensor situated on a wheel and an appertaining evaluation circuit. The sensor system operates especially accurately and reliably if the acceleration sensor is mounted on the wheel in such a way that the main sensing direction lies essentially in the tangential direction of the wheel.
