  • Patent number: 10496195
    Abstract: A touchpad device includes a touch module, communication unit, memory unit, and processing unit. The processing unit receives a touch input sensed by the touch module, performing touch operation detection, and sending one or more operation signals to a terminal device through the communication unit. The processing unit, when detecting a first touch operation occurs on a first mouse button region and ends, sends an operation signal including indication of continuous pressing of a virtual mouse button. The processing unit, when detecting a second touch operation is a sliding movement of a single touch point after the first touch operation ends, sends coordinates-related messages of the sliding movement. The processing unit, when detecting a third touch operation after the first touch operation ends, sends operation signals including a message indicating release of the virtual mouse button and a message indicating an instruction corresponding to the third touch operation.

  • Patent number: 10260511
    Abstract: A ceiling fan includes a body having a disk which is driven by a motor. Multiple frames are connected to the disk and each frame has a rod which is connected between at least two seats and the disk. The at least two seats each are positioned by an inclination angle relative to a horizontal plane. A height difference is formed between the at least two seats of each rod. A blade is connected to each of the at least two seats of each rod of each frame. The ceiling fan includes less number of seats while more blades are connected to the seats.

  • Patent number: 8111126
    Abstract: An over-current protection device comprises a PTC material layer, a first electrode layer, a second electrode layer, a first side electrode and a second side electrode. The PTC material layer is sandwiched between the first electrode layer and the second electrode layer. The first side electrode and the second side electrode are respectively disposed on two opposite side surfaces of the PTC material layer, and are respectively connected to the first electrode layer and the second electrode layer. Furthermore, the first side electrode and the second side electrode are respectively extended to four surfaces adjacent and perpendicular to the two side surfaces.

  • Patent number: 7014943
    Abstract: This specification discloses a thin-film gas diffusion electrode (GDE) and the method for making the same. The thin-film GDE is formed in a unitary way. A dual-nature porous thin film is used as the substrate. A surface processing is performed to make one surface of the thing film hydrophlic while the other surface hydrophobic. The hydrophlic area serves as the active layer for electrochemical reactions after chemical processing. The hydrophobic area is kept dry to form a smooth gas channel, functioning as a gas diffusion layer. In this method, the thin-film GDE is free from the use of binders and high-temperature high-pressure manufacturing processes.
