Abstract: An optoelectronic sensor for detecting and determining the distance of an object in a monitored area is specified with a light emitter having a light source for emitting light pulses, a light receiver for generating a received signal from a light pulse remitted by the object and with a control and evaluation unit, which is designed to control the light emitter and to determine a time-of-flight of the light and, from this, a distance of the object to the sensor. The control and evaluation unit has a time measurement unit which is set up to receive the received signal and a trigger signal and to determine the time-of-flight of the light from a time interval between the trigger signal and the received signal. The sensor further has a trigger circuit that is set up to tap a voltage applied to the light source of the light emitter and to output the trigger signal when an amount of the tapped voltage exceeds a predetermined threshold value.

Abstract: An optoelectronic sensor for measuring a distance using a light time of flight method, comprising a light transmitter for transmitting a light signal, a light receiver having a plurality of light receiving elements for detecting received light, a plurality of light time of flight measuring units for determining respective individual light times of flight, a memory for collecting individual light times of flight, and a control and evaluation unit configured to determine a distance value by evaluating the collected individual light times of flight, wherein a readdressing unit is configured to write individual light times of flight to specific addresses of a same uniform memory depending on the assignment of a light time of flight measuring unit to a group, so that the control and evaluation unit can assign the stored individual light times of flight via the address to a group and thus to a distance value.

Abstract: An adaptive roller conveyor for conveying objects, comprises a plurality of rollers and a control device, wherein the control device is connected with a sensor for detecting at least one parameter of an object, wherein at least one roller is connected with an adjustable brake device, wherein the brake device is connected with the control device, and wherein the control device is configured to control the brake device in dependence on the detected parameter to change the braking effect of the roller.
