Abstract
An active sensor having a transmitter for emitting a measurement signal, having a receiver for receiving the measurement signal, having a transmission link for transmitting the measurement signal, and having an evaluation unit which is configured to register a change in the transmission characteristic of the measurement signal and to generate an output signal, which corresponds to the registered change, the transmitter being configured to emit the measurement signal discontinuously, the transmission power being briefly above a maximum transmission power that is possible during continuous operation and being on average below the maximum transmission power
Claims12
An active sensor system comprising:
- a transmitter for emitting a measurement signal;
- a receiver for receiving the measurement signal;
- a transmission link for transmitting the measurement signal;
- and
- an evaluation unit configured to register a change in a transmission characteristic of the measurement signal, and to generate an output signal corresponding to the registered change, wherein the transmitter is configured to emit the measurement signal discontinuously, whereby the transmission power is briefly above a maximum transmission power which is possible during continuous operation and is on average below the maximum transmission power.
An actuation system comprising:
- an actuator element configured to move against a stop;
- a drive for driving the actuator element;
- a control unit for controlling the drive;
- and
- a sensor system comprising:
- a transmitter for emitting a measurement signal;
- a receiver for receiving the measurement signal;
- a transmission link for transmitting the measurement signal;
- and
- an evaluation unit configured to register a change in a transmission characteristic of the measurement signal, and to generate an output signal corresponding to the registered change, wherein the transmitter is configured to emit the measurement signal discontinuously, whereby the transmission power is briefly above a maximum transmission power which is possible during continuous operation and is on average below the maximum transmission power,
- the sensor system connected to the control unit, wherein the control unit is configured to perform at least one of the following of the group consisting of (i) stopping the drive, and (ii) reversing the drive, if a case of trapping is detected.
