20110006703Light emitting diode illumination device and method for controlling electric current - A light emitting diode (LED) illumination device utilizes a power transmission line to electrically connect a driving module and at least one LED lamp body. The driving module outputs a high frequency alternating power having above 30 voltages and above 72 Hz frequencies through frequency modulation. Each LED lamp body has at least one LED element and a rectification module. The high frequency alternating power generated from the driving module is modulated by the rectification module into a direct power to drive the LED element. Accordingly, the flicker phenomenon on the light source can be effectively improved, and the filter component installed inside each LED lamp body can be omitted. A simple circuit is used to reliably drive the LED element to achieve goals of rapidly developing products and saving costs.01-13-2011

20100271483ULTRASOUND RECEIVING MODULE AND ULTRASOUND DETECTING SYSTEM AND METHOD AND DOCUMENT CAMERA USING THE SAME - An ultrasound receiving module includes an ultrasonic receiver, an amplifier and a detector. The ultrasonic receiver is used to receive at least one ultrasonic signal. The amplifier is electrically connected to the ultrasonic receiver for changing an amplitude of the ultrasonic signal with a predetermined magnification ratio, wherein the predetermined magnification ratio is increased with time. The detector is electrically connected to the amplifier for capturing a portion of the ultrasonic signal above a threshold level, wherein the threshold level is decreased with time.10-28-2010

Patent application numberDescriptionPublished
20100071172CLAMPING APPARATUS WITH POSITIONING FUNCTION - An exemplary clamping apparatus includes a first elongated guide member, a first clamping member, a second clamping member, and a first drive assembly. The first and the second clamping member each moveably attached to the guide member. The first drive assembly includes a motor, a first gear, a second gear meshed to the first gear, a first drive member and a second drive member. The first drive member transmits power from the motor to the first clamping member. The second drive member transmits power from the motor to the second clamping member through the first and second gears. The first and the second drive members are configured for moving the corresponding first clamping member and the corresponding second clamping member towards or away from one another along the guide member.03-25-2010

20090299472LIGHTWEIGHT BREAST PROSTHESIS - A lightweight breast prosthesis is formed as an enclosed body having therein at least two compartments chamber, wherein one of the compartments chamber is filled with silicone gel, and the other compartment chamber or compartments chamber are filled with a substance lighter than silicone gel. Thus, the breast prosthesis, which is soft and tender like silicone gel but lighter than a breast prosthesis made entirely of silicone gel, can serve either as a complete prosthetic breast or as a breast shape-supplementing pad for locally supplementing the breast shape or making up a partially removed breast.12-03-2009

20090146977Liquid Crystal Display and Driving Control Circuit Thereof - A liquid crystal display device and a driving control circuit thereof are provided. The driving control circuit includes a voltage switch unit and a selection unit. The selection unit selects the voltages in accordance with the control signal, while the voltage switch unit outputs the selected voltage to the common terminal of pixels according to the corresponding scan signal. The driving control circuit, controlled by the control signal and the scan signal, can reduce the modulation frequency and the voltage amplitude, so the power consumption of the liquid crystal display device can be reduced.06-11-2009
