A sensor for detecting objects within a monitoring range, with sensor components and an evaluation unit (). An object detection signal is generated in the evaluation unit () in dependence upon sensor signals from sensor components. A selector unit and an input interface () with mechanical setting element are provided, wherein a selection of a parameter set is made in the selector unit () from a number of preconfigured parameter sets in dependence upon a setting configuration of the mechanical setting element of the input interface. The selected parameter set is adopted for the functioning of the sensor.

Sensor

Objects within an area of coverage are located at predetermined points in time with an optical sensor. Based on detected locations of the objects, a driving direction and/or a speed of the vehicle is determined as a function of measuring variables measured with the optical sensor. Based on the determined direction and/or speed, (a) a protective zone is selected among a plurality of protective zones previously stored in the optical sensor, or (b) a validity of a preset protective zone or a preset vehicle parameter value stored in the optical sensor is checked.

Method for identifying an object within a protective zone with a protective device for a vehicle

A circuit arrangement for generating light pulses includes an electro-optical converter; a switching element; and a charge store. The electro-optical converter is connected to the charge store via the switching element. The closing of the switching element triggers a discharging process in the charge store and, in the process, generates an electrical pulse that is converted to a light pulse in the electro-optical converter. First and second impedance matching circuits are arranged, respectively, between the charge store and the switching element and between the switching element and the electro-optical converter.

Circuit arrangement for generating light pulses

An optical sensor arrangement includes a transmitter that emits light rays and a receiver that receives light rays reflected from an object. A deflection unit deflects the transmitted light rays to periodically sweep across a monitoring range. An evaluation unit stores parameters of several safety zones that form respectively predetermined areas of the monitoring range. An object detection signal is generated in the evaluation unit in dependence on receiving signals at the receiver output, which object detection signal indicates whether or not an object is located within an activated safety zone. A communication interface is coupled to the evaluation unit and is operative for bi-directional data transmission with an external unit. At least one of the stored safety zones is activated by reading into the evaluation unit activation signals from the external unit via the communication interface.
