Abstract: A gate valve includes a valve body, a transmission base disposed in the valve body, and two gate plates disposed at two sides of the transmission base. The gate plates are connected together through an elastic member disposed in the transmission base. When the transmission base is located at a first position, the gate plates are received in a chamber and moved towards each other by the elastic member to open valve openings. When the transmission base is located at a second position, the valve openings are sealed by the gate plates, and an elastic positioning portion of the elastic member is abutted against a positioning plate of the valve body for providing a buffer positioning effect to the gate plates. Therefore, the gate valve of the present invention is opened and closed by using the elastic member, and has advantages of smooth movement, simple structure, and good adaptability.

Abstract: Frame running time of a device is estimated dynamically. The device includes a processor that executes threads of an application, and a graphics processor that receives commands from the processor for rendering frames. For each frame, the processor records a timer period for each thread in a set of threads that contribute to operations of a render thread. The render thread writes the commands for the graphics processor to render the frames. Each thread in the set of threads has a corresponding timer that controls a sleep state of the thread. The processor calculates a frame non-running time for a current frame using recorded one or more timer periods, and calculates the frame running time for the current frame by subtracting the frame non-running time from an end-to-end frame period.

Abstract: A gate valve with secure sealing mechanism includes a main body having a valve opening, a driver disposed on the main body, a sliding seat slidingly disposed in the main body, a swing arm, and a valve member. Two ends of the swing arm are connected to the driver and the sliding seat, respectively, whereby the driver drives the swing arm to move circularly between a first and second position, thereby triggering the sliding seat to slide. When the swing arm is at the first or second position, the swing arm is biased against the route direction of the sliding seat. The valve member is disposed on the sliding seat for moving in parallel or vertical to the valve opening, thereby preventing the sliding seat from swaying when the swing arm is at the first or second locking position.

Abstract: A double sealing valve includes a power cylinder having a driving axle, a valve body formed of a first and a second valve members, and a seal plate assembly within the valve body. Therein, the first valve member has an axle bore for the driving axle to pass through, and the second valve member has two valve holes oppositely disposed. The seal plate assembly has a driving frame connected to the driving axle, with plural roller assemblies disposed around the driving frame. The seal plate assembly has two seal plates disposed between two faces of the driving frame and the valve body, respectively. Each seal plate has plural driving grooves corresponding to the roller assemblies. The driving axle drives the seal plate assembly to seal the valve holes, with a sealing force produced therebetween by use of the roller assembly and the driving groove.

Abstract: A data programming method and a system thereof are provided to program an original data into a memory. In the method, the original data complying with a first data arrangement rule is converted into an intermediate data complying with a second data arrangement rule, wherein the second arrangement rule corresponds to a type of the memory. Next, the intermediate data is analyzed to obtain at least one failure area which causes program disturb, and the content of the at least one failure area is replaced by a corresponding adjustment code. The replaced intermediate data is encoded, and a corresponding encoding information is generated. After the encoded intermediate data and the encoding information are both converted into a non-failure data complying with the first data arrangement rule, the non-failure data is programmed into the memory.
