Abstract: A data driving circuit proofed against excessive pixel brightness because of overvoltage on the data line comprises a shift register circuit, a first latch circuit, a second latch circuit, a level shift circuit, a DAC circuit, and an output circuit. The second latch circuit detects a change in the MSB of the data signal of a sampled signal, and outputs a signal for applying a pre-operation of the current data line. When the MSB of the sampled signal is changed, the second latch circuit outputs a pre-operation enabling signal, and whether the grayscale value of the current data line is within a specified region. If within the specified region, the second latch circuit outputs an invalid signal, and the pre-operation is disabled.

Abstract: A coating machine has a receiving box, a releasing device, a length measuring device, a driving roller device and a coating device. The releasing device, the length measuring device, the driving roller device, and the coating device are assembled inside the receiving box. The coating device has a coating pole and a releasing set. The coating pole is arranged below the releasing set. The releasing set has a receptacle to contain an activator. The receptacle has at least one releasing hole to release the activator. The coating machine adopts the coating device with a simplified structure and has a merit of coating the activator evenly.

Abstract: A mobile Virtual Reality (VR) system includes a display unit, a sensing unit, a photographing unit and a VR application. The sensing unit senses a physical movement variation of the mobile VR system. The photographing unit photographs environment to generate a photograph image. Based on the physical movement variation of the mobile VR system from the sensing unit and the photograph image from the photographing unit, the VR application determines a movement status of the mobile VR system to adjust a VR display image on the display unit.

Abstract: A read, write, and match circuit for a low-voltage content addressable memory. A write circuit inputs signals for storing data in the memory cells, a read circuit retrieves the stored data from the memory cells, and a match circuit compares the data stored in the memory cell with the data searched by the match circuit. The circuits for writing, reading and matching are separated from each other and exempt from mutual interference.

Abstract: The present invention discloses a read and match circuit for a low-voltage content addressable memory, wherein the write circuit inputs the signals needing storing into the memory cells, and the read circuit retrieves the stored signals from the memory cells, and the match circuit compares the data stored in the memory cell with the data searched by the match circuit. As the circuits for writing, reading and matching are separated from each other and exempt from mutual interference, the present invention can achieve high reliability and low power consumption under a low-voltage operation environment without using a special fabrication process. In the present invention, the circuit is optimized to meet different requirements. The present invention enables the user to determine whether to have high speed or to have low power consumption. Further, the present invention can overcome the problems of current leakage and noise allowance in a low-voltage environment.
