Abstract: Provided is a method for compensating light reflections from a cover of a time-of-flight camera in an image of a scene that is sensed by the time-of-flight camera. The method includes receiving the image of the scene from the time-of-flight camera. Further, the method includes modifying the image of the scene using a reference image to obtain a compensated image of the scene. Pixels of the reference image indicate reference values exclusively related to light reflections from the cover of the time-of-flight camera. Additionally, the method includes outputting the compensated image.

Abstract: A method for compensating stray light caused by an object in a scene that is sensed by a time-of-flight camera is provided. The method includes receiving an image of the scene from the time-of-flight camera. Further, the method includes controlling the time-of-flight camera to capture a reference image of the scene using a code modulated signal for illumination such that a measurement range of the time-of-flight camera is limited to a distance range around the object. The method additionally includes modifying the image of the scene or an image derived therefrom using the reference image to obtain a compensated image of the scene. The method includes outputting the compensated image.

Abstract: It is described a radar system (100), comprising: i) a transmitter (110) having a transmitter carrier characteristic, configured to transmit a code signal (S); ii) a receiver (120) having a receiver carrier characteristic, configured to receive an echo (E) of the code signal (S); and iii) a control unit (130) configured to: a) identify a carrier characteristic tracking path (T) between the transmitter (110) and the receiver (120), b) estimate an offset between the transmitter carrier characteristic and the receiver carrier characteristic based on the identified tracking path (T), and c) compensate for the offset, in particular establish coherency, based on the estimation. iv) The tracking path (T) comprises hereby a communication path that is at least partially independent of the code signal (S) and the echo (E) of the code signal (S).

Abstract: Examples relate to a method for determining distance information of an object using a Time of Flight (ToF) system and to a ToF system. The method includes emitting modulated light towards the object using a light source. The method includes measuring a reflection of the modulated light using a ToF sensor module. The reflection of the modulated light is generated by successive reflections of the modulated light by the object and by an additional reflective surface. The method includes determining the distance information of the object based on the measured reflection of the modulated light.

Abstract: A power supply circuit is described herein which is capable of sourcing energy from an NFC antenna. In one embodiment, the circuit comprises a rectifier circuit configured to be coupled to an NFC antenna for receiving an antenna voltage, a filter coupled to an output of the rectifier circuit and configured to provide the rectified and smoothed antenna voltage as supply voltage, and a current limiting device coupled between the filter and an output node and configured to limit an output current provided at the output node dependent on a control signal. Further, the power supply circuit comprises a control circuit configured to receive the supply voltage and a reference voltage and to generate the control signal dependent on a difference between the reference voltage and the supply voltage.
