摘要： A sensor arrangement comprises a communication device and a sensor element. The sensor element is configured to record a property and provide a sensor signal that represents the property. The sensor arrangement comprises a security element configured to provide a secret. The sensor arrangement is configured to link the sensor signal to the secret to obtain a linked sensor signal, transmit the linked sensor signal to a communication partner using the communication device, obtain a test signal from the communication partner using the communication device, and perform a check to determine whether the test signal comprises the secret.

摘要： An object sensor test system includes a sensor and a test bench. The sensor includes a receiver configured to receive a simulated optical signal and a processing chain that includes a plurality of processing components configured to process at least one measurement signal generated in response to the simulated optical signal to generate processed test data. The sensor also includes a test interface configured to receive a control signal, and selectively extract processed test data at a selected output of the processing chain based on the control signal. The test bench is configured to transmit the control signal to the test interface, receive the processed test data from the sensor, compare the received processed test data with expected data to generate a comparison result, and determine that a segment of the processing chain is operating normally or abnormally based on the comparison result.

摘要： An apparatus for localizing a first device includes a time of flight circuit configured to emit a first modulated light signal and receive a reflection of the first modulated light signal from the first device. The apparatus further includes a processing circuit configured to determine, based on the first modulated light signal and the reflection, a position of the first device in a first coordinate system associated with the apparatus. The processing circuit is further configured to determine, based on the position of the first device in the first coordinate system, a position of the apparatus in a second coordinate system and an orientation of the apparatus in the second coordinate system. The apparatus further includes a transmit circuit configured to emit a second modulated signal to the first device, wherein the second modulated signal includes data indicating the position of the first device in the second coordinate system.

摘要： Exemplary embodiments include a dual-mode optical device having an optical reflector, an optical transmitter, and a detector. The optical reflector is configured to reflect an incident first optical signal having a first wavelength, wherein the first optical signal includes a plurality of intermittent active and inactive durations. The optical transmitter is configured to emit a second optical signal having a second wavelength substantially similar to the first wavelength. The detector is configured to: determine the active and inactive durations of the first optical signal; and inhibit the optical transmitter from emitting the second optical signal during the detected active durations of the first optical signal.

摘要： An apparatus comprises an input interface for receiving a color image of at least an object and a low resolution depth image of at least the object. The apparatus further comprises an image processing module configured to produce data for generating a three-dimensional color image based on a first color pixel image data of a first color pixel and a first derived depth pixel image data of a first derived depth pixel. The image processing module is configured to calculate the first derived depth pixel image data based on a measured depth pixel image data of a measured depth pixel and a weighting factor. The weighting factor is based on a color edge magnitude summation value of a path between the first color pixel and the reference color pixel. The apparatus further comprises an output interface for providing the generated three-dimensional color image.
