Abstract: A drive assembly of an electric bicycle is disclosed. A shell tube of an electric bicycle is transfixed with a crank shaft sheathed with an outer shaft set. The outer shaft set links to a tubular motor set. A first side of the crank shaft is provided with a left positioning set sheathed and limited in a left hole of the shell tube. A second side of the crank shaft is provided with a right positioning set sheathed and limited in a right hole of the shell tube. The right positioning set is fixed with a chain wheel set. A displacement of the crank shaft pulled by a bicycle chain is detected by a torque detection unit, and a torque is accessed by a control unit based upon the displacement to control the output power of the tubular motor set, thereby assisting pedaling the bicycle with feet.

Abstract: A gas valve consists of a valve body. The valve body includes an inlet passage and a pilot passage. Said pilot connects to the inlet passage and a pilot ignition device set outside the valve body. Gas is led into said valve body through the inlet passage, passing said pilot passage, and is brought into the pilot ignition device. Said gas valve is characterized in that two solenoid valves are installed in the pilot passage. Said solenoid valves can open and shut the pilot passage, and when one of the solenoid valves function incorrectly, another valve will serve as an auxiliary, impeding the gas flow being delivered to the pilot ignition device, improving safety measure of the gas valve.

Abstract: The present invention discloses an organic light emitting diode display, a driving method therefor and a pixel unit thereof. The organic light emitting diode display comprises a pixel array comprising a plurality of organic light emitting diode (OLED) pixel groups of different colors, such as red, green and blue. The organic light emitting diode display can determine the ratio of shortened light emission intervals of OLED pixel groups of a specific color based on the color distribution of an image, thereby effectively prolonging the life of the OLEDs of a specific color. In one embodiment, the pixel unit of the organic light emitting diode display comprises an OLED, a switch and a drive circuit. The switch controls whether or not the current outputted from the drive circuit flows to the OLED so as to achieve the effect of the above-mentioned shortened emission interval.

Abstract: A touch display device, a touch display system, and a method for adjusting a touch area thereof are disclosed. The touch display system comprises a computer system and the touch display device. The touch display device provides a touch area with a touch control function. The method comprises following steps: receiving an image signal and displaying an image representing the image signal on the touch display device; detecting and obtaining a signal resolution of the image signal; detecting and obtaining a display status displayed by the touch display device, wherein the signal resolution and the display status are used to determine the boundary of the image; determining whether the touch display device simultaneously displays the image and an inactive area, wherein the inactive area is the region where the touch display device does not display the image; and if yes, adjusting the coordinates of the touch area such that the touch area and the image correspond with each other.
