  • Patent number: 8624461
    Abstract: A motor stator includes an insulating frame having a plurality of projecting rods, an induction unit, and a plurality of conductive members. The induction unit includes an induction circuit board, a plurality of induction coils embedded within the induction circuit board, and a plurality of coil windings wound respectively on the projecting rods. The conductive members extend through the insulating frame and the induction circuit board for establishing an electrical connection between each of the induction coils and a corresponding one of the coil windings. The turn numbers of the coil windings are not limited by the area and thickness of the induction circuit board, and can be increased. Alternatively, the coil windings may be positioned to increase the magnetic pole slot number when energized. As such, a driving force of the motor stator can be increased.

  • Patent number: 7860123
    Abstract: A wireless communication apparatus includes a first interface, a packet memory, a shift register set, and a second interface. The first interface receives a plurality of packets and stores the plurality of packets in the packet memory. The addresses of the plurality of packets stored in the packet memory are recorded in the shift register set. The second interface reads the packets in the packet memory according to the addresses of the packets recorded in the shift register set and then sends to a receiver. After an acknowledge signals from the receiver is received, the addresses of the successfully transmitted packets are cleared from the shift register set.

  • Publication number: 20050240693
    Abstract: The present invention provides a multi-functional peripheral apparatus to be connected to a host. The apparatus comprises a connection module, a plurality of peripheral modules, and a control module. The connection module provides a transmission interface to receive a peripheral output signal from the host. Each of the peripheral modules performs a specific peripheral function. The peripheral modules further comprise a data storage memory to store at least one peripheral driver. The control module receives the peripheral output signal from the connection module and produces a corresponding peripheral control command to control and to enable the selected peripheral module specified in the peripheral output signal to perform the corresponding specific peripheral function. When the apparatus is connected to the host, the host allows the control module to install the peripheral driver into the host so that the host employs the driver to drive the selected peripheral modules.
