Latest Patents

Among his latest patents, Jianping Xie has developed a "Pointing device with optical positioning on low-diffusive surfaces." This invention features a computer input device that includes a light source assembly, which forms an incident light beam striking a surface beneath the device at a large incident angle. A light sensing assembly is positioned to receive scattered light, incorporating a band-pass filter. Additionally, a barrier is placed above the area where the light beam strikes to prevent direct light from reaching the light sensing assembly.

Another notable patent is the "Input device using laser self-mixing velocimeter." This device encodes motion by directing a laser beam at a moving member, such as a disk. The reflected light from the beam creates fluctuations in the beam power output due to the self-mixing effect, generating a beat signal. This signal's frequency is utilized to determine the speed and direction of the member's motion, showcasing Xie's innovative approach to motion detection.
