Abstract: A portable information handling system interacts with a game controller through either a direct connection at a wired interface at the sides of opposing controller housings and the information handling system housing or through a bridge having a bridge housing that directly couples to the controller housing as a bridge to the information handling system, such as with a wireless interface. During a sliding coupling motion, pins of the controller housing wired interface move across pins of the bridge or information handling system wired interface. Analysis of the interface signals through a sliding coupling motion identifies the type of controller housing, such as a controller housing with game input devices or with extra functions like speaker audio and supplemental battery power.

Abstract: A power-saving method for a wheel mouse is provided. The power-saving method is used to control the illumination cycle of a light emitter by judging whether a scroll wheel is triggered or judging whether the output signal from the light receiver is changed. In a case that the illumination cycle of the light emitter is a shorter second cycle, the light emitter can quickly generate the optical signal. Consequently, the optical signal is not lost, and the possibility of erroneously operating the wheel mouse is eliminated. Whereas, in a case that the illumination cycle of the light emitter is a longer first cycle, the controlling unit can reduce the power consumption in order to achieve the power-saving efficacy.
