  • Publication number: 20140367911
    Abstract: A touch position determining apparatus and method thereof are provided. The touch position determining apparatus is adapted to a sphere. The touch position determining apparatus includes a pressure sensing array and a processing unit. The pressure sensing array is coupled below the sphere and includes a plurality of pressure sensing nodes. The pressure sensing array generates a pressure deformation area in response to a touch operation performed on a surface of the sphere, and generates a pressure signal set by the pressure sensing nodes corresponding to the pressure deformation area. The processing unit is connected to the pressure sensing array and determines a touch position of the touch operation performed on the surface of the sphere according to the pressure signal set.

  • Patent number: 7509444
    Abstract: This invention discloses a data access device for using in computer of power off status, which comprises a power multiplexer, a DC to DC converter, a serial bus signal to storage interface signal controller, a data storage interface signal multiplexer, and a controller. Therefore, if controller detects an external device wants to access data storage device of computer at power off, it will control power multiplexer to retrieve the standby power of the power device and process power transformation to provide a required power for driving the storage device, and by using serial bus signal to storage interface signal controller, external device can access the data from storage device at power off.

  • Patent number: 5918057
    Abstract: An interrupt processing method and apparatus particularly well-suited for use in an interrupt controller of a multiprocessor system or device. Each of the interrupt requests has at least one destination processor associated therewith for servicing the interrupt request. An interrupt controller in accordance with the present invention applies latched interrupt requests to a priority compare tree which serves to prioritize received interrupt requests. A number of higher priority requests, including the highest priority request, are supplied to a destination selection circuit which includes an interrupt dispatcher which determines a processor to which the first priority interrupt request will be dispatched. Similar determinations are made for the remaining identified interrupt requests, but with the corresponding destination register contents masked to prevent processors already selected to receive a higher priority interrupt from being considered for a lower priority interrupt.
