Abstract: A method is for detecting one or more objects in a detection zone using a time-of-flight sensor. The method includes emitting optical radiation via the emission circuitry of the sensor and subsequently capturing the reflected optical radiation using the reception circuitry. This captured radiation is quantified in terms of photons, and measurement circuitry determines both the amount of these photons and the distance from the sensor to the object(s). An analysis of the photon count, combined with the calculated distance, is used to determine the presence or absence of objects within the detection zone.

Abstract: Described herein is a time-of-flight ranging system and methods for its operation. The system includes an array of single photon avalanche diode (SPAD) pixels and control circuitry. The control circuitry simultaneously accumulates integrated SPAD event data from one cluster of SPAD pixels while integrating SPAD event data from another cluster during different target illuminations. The system also includes first and second VCSEL clusters, each responsible for a different target illumination. By processing and managing the data in this manner, the system can effectively reduce the time used to gather and analyze the event data, leading to faster and more accurate distance measurements.

Abstract: In response to a request to store new data at a memory location of a bitwise programmable non-volatile memory, data stored at the memory location of the bitwise programmable memory is sensed. The bits of the sensed data are compared with bits of the new data. An indication of a cost difference is determined between a first burst of bitwise programming operations associated with programming bits of the new data which are different from bits of the sensed data, and a second burst of bitwise programming operations associated with programming bits of a complementary inversion of the new data which are different from bits of the sensed data. One of the first burst of bitwise programming operations or the second burst of bitwise programming operations is executed based on the generated indication of the cost difference.
