Abstract: Embodiments include a smart personal gateway device (SPGD) that augments the capabilities of smart personal devices (SPDs) connected in a personal area network (PAN). The SPGD implements services for the SPDs using computing resources of the SPGD. In some embodiments, the SPGD provides carrier-grade voice services to SPDs lacking hardware to support such services (e.g., SPDs supporting Wi-Fi only).

Abstract: An optical navigation chip cooperated with a light source for being used in a mouse is provided. The mouse transmits a mouse signal to a computer for navigation control. The optical navigation chip includes an optical sensing array and a circuitry. The optical sensing array is utilized for receiving a reflected light from a surface indicating features of the surface for generating a digital frame corresponding to intensity variation caused by the reflected light. The circuitry is coupled to the optical sensing array, and utilized for generating a digital displacement signal by monitoring the intensity variation of two different digital frames, wherein the two digital frames are captured by the optical sensing array at two different times. Additionally, the mouse suspends the mouse signal to the computer if the intensity variation is flat.
