Abstract: A semiconductor device includes first to fourth terminals, a switch circuit, and an integrating circuit. The integrating circuit includes an amplifier circuit having a (?) terminal, a first (+) terminal, and a second (+) terminal. The integrating circuit is configured to integrate an input signal of the (?) terminal using an average voltage of a voltage of the first (+) terminal and a voltage of the second (+) terminal as a reference voltage. The switch circuit is configured to electrically connect the (?) terminal to the second terminal, the first (+) terminal to the first terminal, the second (+) terminal to the third terminal the (?) terminal to the third terminal, the first (+) terminal to the second terminal, and the second (+) terminal to the fourth terminal. The present semiconductor device is used as a semiconductor device sensing a current flowing through a pixel in a display panel.

Abstract: An auxiliary switch is provided that allows a thermostat to use full wave rectification for power while still communicating control information to the auxiliary switch over a multiplexed ground-control line to control associated equipment.

Abstract: Improved, magnetic high security switch apparatus is provided for use in detecting relative movement between first and second members such as a door frame and door from a close position, wherein the members are proximal, and an open position, where the members are separated. The switch apparatus includes a magnetic shiftable ball switch assembly having an elongated housing and a shiftable ball therein, which traverses an oblique path of travel between respective switch states in response to relative movement between the first and second members. Preferably, the housing is oriented at an oblique angle relative to the horizontal in order to prevent defeat of the switch apparatus through use of an external defeat magnet.
