Latest Patents

One of Zhang's latest patents is for a near-field optical sensing system. This invention provides systems, methods, and apparatus for sensing touch and gestures in the near-field area overlying a light-guiding layer within a device. The system utilizes modulated infrared light, which is emitted into the overlying area, and the light reflected by objects is redirected through the light-guiding layer to infrared sensors. Additionally, a masking structure can be positioned between the light-guiding layer and the infrared sensors, and techniques such as probability mapping or backtracing can estimate the locations of objects within the area.

Another significant patent is for an electronic device designed for defect detection. This device includes a processor and instructions stored in memory that communicate electronically with the processor. It performs background suppression on image data to obtain a score map and applies thresholding to generate a detection mask. The device utilizes bi-thresholding for thresholding and detects any defects based on the detection mask, indicating the presence of defects effectively.
