Abstract: A power supply having a power protection circuit has a rectification circuit and a converter. An input terminal of the rectification circuit is connected with the AC mains. A first voltage dependent resistor is connected with the AC mains. The converter has a transformer. A primary side of the transformer is connected with an output terminal of the rectification circuit, and the secondary side is connected to a power output terminal and a ground terminal. A Y capacitor is connected between the primary side of the transformer and the ground terminal. A surge protection module is connected between the first voltage dependent resistor and the Y capacitor.

Abstract: A system and method for image sensing is disclosed. An embodiment comprises a substrate with a pixel region, the substrate having a front side and a backside. A co-implant process is performed along the backside of the substrate opposing a photosensitive element positioned along the front side of the substrate. The co-implant process utilizes a first pre-amorphization implant process that creates a pre-amorphization region. A dopant is then implanted wherein the pre-amorphization region retards or reduces the diffusion or tailing of the dopants into the photosensitive region. An anti-reflective layer, a color filter, and a microlens may also be formed over the co-implant region.

Abstract: In a fan noise canceling system, a feedforward signal generated when a fan speed change occurs and a feedback signal read by a sensor are sent to a signal amplifying unit for signal amplification, and the amplified signals are then sent to a signal converting unit for converting into a digital signal. A hybrid controller receives and corrects the digital signals sent thereto, and conducts rapid convergence algorithm to derive a reverse digital signal. The reverse digital signal is sent back to the signal converting unit for converting into a reverse analog signal, which is then sent to the signal amplifying unit for power amplification and generating a control signal to drive a loudspeaker to produce a reverse acoustic wave, which cancels out wave of fan noise to effectively reduce fan noise without adversely affecting the heat dissipation effect of the fan.

Abstract: In a communication machine room wideband noise suppression system, a sensing unit detects a noise source produced by a fan during the operation thereof and generates a noise input signal and a feedback signal, which are sent to a signal amplifying unit for signal amplification. The amplified signals are then sent to a signal converting unit and converted into digital signals. A multi-channel hybrid controller receives the digital signals and makes corrections and conduct rapid convergence algorithm to derive a reverse digital signal, which is sent to the signal converting unit and converted into a reverse analog signal. The reverse analog signal is sent to the signal amplifying unit for power amplification to generate a control signal for driving a loudspeaker unit to produce interfering acoustic wave, so as to cancel out the noise source and achieve the purpose of eliminating wideband noise.
