  • Patent number: 8145811
    Abstract: A universal serial bus (USB) driving device electrically coupled to a data receiver is configured for driving a USB to forward data requests from the data receiver to a data transmitter for processing the data requests. The USB driving device may preset a maximum active transaction number, initialize an active transaction number, and determine if the active transaction number is less than the maximum active transaction number. The USB driving device may drive the USB to forward a data request from the data receiver to the data transmitter if the active transaction number is less than the maximum active transaction number and increase the active transaction number after the USB driving device forwards a data request to the data transmitter. A USB driving method is also provided.

  • Publication number: 20070229768
    Abstract: A projection apparatus including a projection module, a control unit, a housing, a wireless-receiving unit and a control panel is provided. The control unit is electrically connected to the projection module for controlling the projection module. The housing is suitable for accommodating the projection module and the control unit and has a concavity exposed outside. The wireless-receiving unit is disposed inside the housing and is electrically connected to the control unit. The control panel is detachably installed in the concavity. When the control panel is installed in the concavity, the control panel is electrically connected to the control unit such that the control panel is suitable for providing an electric signal to the control unit for controlling the projection module. When the control panel is detached from the concavity, the control panel is suitable for providing a wireless signal to the wireless-receiving unit for controlling the projection module.
