Abstract: A hinge system for opening a cover pivotably connected to a device housing. The hinge system includes a rotating member in the device housing and a shaft connected between the cover and the rotating member. A non-rotating member in the device housing receives the rotating member and a spring connected to the device housing and biased to rotate the shaft.

Abstract: An apparatus provides an electronic signal in response to at least one of an applied force and an applied torque. The apparatus includes a detection device that detects movement of a movable member relative to a base, and provides the electronic signal, by driving a plurality of first sensor components.

Abstract: A force and torque converter provides an electronic signal in response to at least one of an applied force and an applied torque. The converter includes a base, a movable member that provides movement relative to the base in response to the at least one of the applied force and the applied torque, a controlling mechanism, and a detection circuit. The controlling mechanism has a plurality of resilient mechanisms, connected to the base and co-acting with the movable member, that provide at least one of a restoring force and a restoring torque to the movable member in response to the at least one of the applied force and the applied torque. The controlling mechanism further includes a restraining member, disposed within the movable member, that restrains the movable member when the movable member is in contact with the restraining member. The detection circuit co-acts with the controlling mechanism, to detect the movement of the movable member relative to the base, and provide the electronic signal.
