Latest Patents

One of his latest patents is a "Time-of-flight device using two light modulation frequencies and operating method thereof." This invention includes a distance measurement device that comprises a light source, a light detector, a time control circuit, and a processor. In the first measurement, the time control circuit manages the light source to illuminate at a low modulation frequency. The processor then calculates a rough flying time based on the first detection signal from the light detector to determine an operating phase zone and a delay time. In the second measurement, the light source illuminates at a high modulation frequency, allowing the processor to calculate a fine flying time based on the second detection signal.

Another notable patent is the "Single photon avalanche diode based optical sensor, event-based vision sensor and operating method thereof." This optical sensor features an SPAD pixel array, multiple counters, and a processor. The counters tally photon events from the SPAD pixel array to produce an event-based vision sensor (EVS) frame per EVS period. The processor assesses the index state of each pixel by comparing counting values at predetermined checking points with two thresholds, enhancing the sensitivity of the event-based vision sensor.
