Abstract: A device for monitoring the door area around a that is at least partially glazed door is provided. A transmitter emits a transmission pulse of electromagnetic radiation. An image recorder comprises a receiver matrix having a first receiver blocks which has a plurality of first receivers. The first receivers receive reflected signal components of the transmission pulse. Each first receiver has a memory unit which is designed to integrate and store the reflected signal components received. A control unit triggers a transmission pulse of the transmitter and activates the first receivers for a predetermined first receiving period. An evaluation unit compares topography image data with stored reference image data or compares a respective distance value with a stored reference value for a door area free of objects.

Abstract: A registration system for classifying an object, comprising a sensor unit, an evaluation unit, a memory unit and a data-processing unit. The evaluation unit determines a structure data set or a temporal sequence of structure data sets of the object to be registered from a temporal progression of the radiation captured by the sensor assembly. The memory unit stores association rules, each associated with a set of situation parameters. The data-processing unit accesses the structure data set or a temporal sequence of structure data sets, the current situation parameter set, and the association rule associated with the current parameter set and to associate an object with an object class on the basis of the structure data set associated with the object or a temporal sequence of structure data sets by using an association rule associated with the current situation parameter set and received from the memory unit.

Abstract: The invention relates to imaging 3-D time-of-flight sensors that are particularly suitable for the detection of objects and individuals in three-dimensional space. This capability results from the basic principle. In each image point of the sensor, the distance to the object located in the observation space is determined by using the propagation time (time of flight) of light pulses. The sensor therefore supplies a three-dimensional image, which can be analyzed by means of suitable processing algorithms. In specific applications, in particular in the interaction of human and machine, machine and machine, or machine and space, it is necessary that the detection is carried out safely. The level of safety is classified in various standards into safety integrity levels.

Abstract: The invention relates to a device for monitoring the door area of an at least partially glazed door. The device comprises a transmitter, an image recorder, a control unit, and an evaluation unit. The transmitter is used to emit at least one transmission pulse of electromagnetic radiation. The image recorder comprises a receiver matrix having at least one first receiver block, which has a plurality of first receivers. The first receivers of the first receiver block are designed and arranged in such a way that they receive reflected signal components of the transmission pulse in a second predetermined distance range of an outer region of the door area, the distance range being determined in relation to the door. Each first receiver has a memory unit which is designed to integrate and store the reflected signal components received.

Abstract: The invention relates to a sensor system for recording a hand vein pattern. The sensor system comprises a first light source, which is designed to emit, during operation, electromagnetic waves in the near infrared range, which are able to be reflected by veins in a hand, over the entire surface, a camera having a camera chip for recording reflection signals for electromagnetic waves and for delivering image data that correspond to the reflection signals, a topography sensor for sensing three-dimensional topographies and a first processor unit, which is connected to the camera chip and to the topography sensor. The first processor unit is designed to generate from the image data from the camera and the three-dimensional topography data from the topography sensor, during operation, a normalized vein pattern for a hand or a feature vector that corresponds to the vein pattern.
