Abstract: A capacitive touch apparatus includes a first touch unit, a first voltage difference retrieving unit, a first feedback signal generating unit, and a control unit. The first touch unit has a touch substrate and a first conductive layer. The first voltage difference retrieving unit is electrically connected with the first conductive layer and outputs a first voltage signal and a second voltage signal. The first feedback signal generating unit outputs a first feedback signal according to the variation of the voltage difference between the first voltage signal and the second voltage signal. The control unit receives the first feedback signal for computing the touch position and outputs a power signal to the first voltage difference retrieving unit. Hence, the capacitive touch apparatus improves the sensing speed and reduces the manufacturing cost by the simple circuit design.

Abstract: A magnetic actuator. A yoke includes a first opening and a second opening, a frame, and a path. A first magnet is disposed in the first opening in the vicinity of the frame. A second magnet is disposed in the second opening in the vicinity of the frame. A coil comprises a wire surrounding the path. A light shield is connected to an end of the coil. A guiding element disposed outside the path is connected to an end of the coil. When current passes through the coil, the coil moves along the path by magnetic induction between the first magnet and the second magnet such that the iris diaphragm is adjustable by the light shield. When there is no current through the coil, dynamic force produced by the guiding element returns the light shield to its original position.

Abstract: A wavelength stabilizing apparatus utilized in an optical communication system for controlling a light wave output from a tunable optical component is disclosed. The wavelength stabilizing apparatus includes a coarse-tuning element, a fine-tuning element, and a servo element. When the wavelength stabilizing apparatus is used, the light wave output from the tunable optical component is directed into the coarse-tuning element and the fine-tuning element, respectively, and then transformed into electric signals to be received by the servo element. Particularly, the electric signals from the coarse-tuning element are served as basis for coarse-tuning and channel recognition of the light wave output from the tunable optical component while the electric signals from the fine-tuning element are served for fine-tuning and servo control of the light wave output from the tunable optical component. These electric signals are also processed with a logical operation to obtain a control signal for controlling the tunable optical component.
