A method of determining a temporal position of a received signal within a sample series is disclosed. The method includes sampling a sensor at a sampling frequency to generate the sample series. A matched filter set of matched filters is applied to the sample series to generate a matched filter correlation set of matched filter correlations, wherein impulse responses of respective matched filters correspond to a template signal at the sampling frequency of the sensor shifted by a sub-interval shift. The matched filter correlations are evaluated to determine a received signal sub-interval shift. The temporal position of the received signal within the sample series is determined based on at least the received signal sub-interval shift.

Signal temporal position determination

A receiver for a light detection and ranging system includes detecting elements, each configured to convert light into an analog detection signal. The receiver includes a first converting element configured to provide a first digital detection signal in response to a first analog detection signal. The first converting element is configured to use a first number of bits to represent the first analog detection signal. The receiver includes a second converting element configured to provide a second digital detection signal. The second converting element is configured to use a second number of bits to represent the second analog detection signal. The second number of bits is greater than the first number of bits. The receiver comprises a processing module configured to determine a first parameter of an object using the first digital detection signal and a second parameter of the object using the second digital detection signal.

LIDAR system, a method for a LIDAR system and a receiver for LIDAR system having first and second converting elements

A LIDAR system includes a receiver configured to receive a reflected light beam from a receiving direction, the reflected light beam having an oblong shape that extends in a lengthwise direction. The LIDAR receiver includes a two-dimensional (2D) photodetector array including a plurality of pixel rows and a plurality of pixel columns, wherein the reflected light beam, incident on the 2D photodetector array, extends in the lengthwise direction along at least one receiving pixel column of the plurality of pixel columns according to the receiving direction; an analog readout circuit including a plurality of output channels configured to read out electrical signals; and a multiplexer configured to, for each reading cycle, selectively couple receiving pixels of the at least one receiving column to the plurality of output channels based on the receiving direction, while decoupling non-receiving pixels from the plurality of output channels based on the receiving direction.

Presented are methods and devices for issuing an authorization for access to a secured area, particularly a building, a room, a vehicle, a computer system or the like, or for starting a machine, a vehicle, a computer or the like, having a monitoring unit comprising a transmitter, a receiver, and an evaluation device, and having a key, a key card or similar, referred to as a key in short below, having a transmitter, a receiver and an electronic device. A permissible position and/or a permissible distance between the transmitter of the monitoring unit and a permissible key is determined prior to issuing an authorization, wherein the transmitter of the monitoring unit transmits signals and the key transmits response signals back to the monitoring unit. The permissible position and/or the permissible distance of the key are determined from the signals received by the key, wherein a signal strength of said signals is evaluated in various directions and/or angles.
