  • Patent number: 8545323
    Abstract: A compact game controller incorporates an efficient and compact force feedback mechanism. Forces are generated at one of the controls of the controller in reaction to an action in a video game. The type of controller that can be held with two hands is limited in terms of size and internal space and in wireless versions is limited in terms of battery power. Efficient power consumption in the controller enables considerable usage time between battery replacement or recharging in wireless versions. The force feedback mechanism incorporates a double reduction gear system with a unique geometry which enables usage of a compact and energy efficient motor. The efficient force feedback mechanism and assembly can therefore be packaged within a compact ergonomic controller.

  • Patent number: 8238407
    Abstract: Automatic establishment of a connection between a human interface device and a host transceiver unit. A marriage ID is exchanged in a synchronization step. The marriage ID being used by both the host transceiver and the human interface device to calculate a spread spectrum modulation pattern. In one embodiment the spread spectrum modulation is a frequency hopping spread spectrum modulation.

  • Patent number: 7254159
    Abstract: A system and method for the automatic establishment of a connection between a human interface device and a host transceiver unit, wherein the system includes a host transceiver unit configured to be connected with a host via a bus, and configured to wirelessly exchange data with a human interface device; a human interface device configured to wirelessly exchange data with a host transceiver; and a computer readable media having instructions thereon, wherein said instruction include routines for synchronizing the host transceiver unit and the human interface device for wirelessly exchanging data between the host transceiver unit and the human interface device at a spread spectrum modulation pattern which is determined by the host transceiver after the host transceiver unit and the human interface device have acknowledged each other's presence.
