Abstract: An optical sensor includes pixels. Each pixel has a photodetector. A readout circuit performs a process over an exposure time where the photodetector is connected to a reverse bias voltage supply to reset a voltage across the photodetector, and the photodetector is disconnected from the reverse bias voltage supply until that the voltage across the photodetector decreases in response to received ambient light. An ambient light level is then determine an based on a number of times the voltage across the photodetector is reset over the exposure time.

Abstract: An indirect time-of-flight measurement sensor includes a photosensitive pixel array configured to acquire a succession of images of a scene during a given exposure time. The sensor includes a control unit configured to control the acquisition of the succession of images by the pixel array and to define an exposure time for this acquisition based on a pixel saturation rate of the array, distances between the sensor and elements of the scene, and a standard deviation of the distances between the sensor and the elements of the scene.

Abstract: A non-conductive encapsulation cover is mounted on a support face of a support substrate to delimit, with the support substrate, an internal housing. An integrated circuit chip is mounted to the support substrate within the internal housing. A metal pattern is mounted to an internal wall of the non-conductive encapsulation cover in a position facing the support face. At least two U-shaped metal wires are provided within the internal housing, located to a side of the integrated circuit chip, and fixed at one end to the metallic pattern and at another end to the support face.

Abstract: An integrated circuit package includes a support substrate having a front side and a back side and an optical integrated circuit die having a back side mounted to the front side of the support substrate and having a front side with an optical sensing circuit. A glass optical element die has a back side mounted to the front side of the optical integrated circuit die over the optical sensing circuit. The mounting of the glass optical element die is made by a layer of transparent adhesive which extends to the cover the optical sensing circuit and a portion of the front side of the optical integrated circuit die peripherally surrounding the optical sensing circuit. An encapsulation material body encapsulates the glass optical element die and the optical integrated circuit die.

Abstract: A method includes receiving a histogram output from a detector sensor, and calculating a median point of a pulse waveform within the histogram. The pulse waveform has an even probability distribution over at least one quantization step of the histogram around the median point. A corresponding apparatus can include a detector sensor and a co-processor coupled to the detector sensor.

Abstract: In accordance with an embodiment, a method verifies contents of a plurality of registers having two first registers, where each of the plurality of registers is configured to store a data word and a verification bit. The method includes determining whether a value of the verification bit of each respective register of the plurality of registers corresponds to the data word of its respective register. The data words stored in the two first registers are selected so that the bits of a same rank of the two first registers include two complementary bits, each bit of a common binary word is associated with a respective register of the plurality of registers, and the value of the verification bit of each respective register depends on the data word of the respective register and the bit of the common binary word associated with the respective register.

Abstract: A measurement of the rotation speed of an object is made using a time-of-flight sensor configured to detect a passing of one or more of elements of the object through a given position. The time-of-flight sensor is further mounted on a one-person vehicle configured to protect the one-person vehicle against collisions through the making a time-of-flight measurement of a relative speed between the one-person vehicle and an obstacle.
