Latest Patents

One of Yu-Ju Lee's latest patents is a finger detection device and operating method. This device includes a light source, a light sensor, and a processor. The light sensor captures two image frames corresponding to the light source being turned on and off. The processor then calculates a differential image frame and determines whether the covered region is a finger region. If it is not, the processor acquires new image frames. If it is, the processor identifies different windows of interest within the finger region.

Another significant patent is for an electronic device that can be unlocked using sequential fingerprints. This device features a touch pad, a processor, and an operating system. The touch pad collects fingerprint data over multiple time intervals. The processor recognizes each fingerprint according to the collected data. When a sequence of fingerprints matches a predetermined condition, the processor unlocks the electronic device.
