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.

High-frequency wireless peripheral device with auto-connection and auto-synchronization

A wireless human interface device configured to establish a link with a host, wherein the device includes a transceiver for transmitting data to and receiving data from a host transceiver unit, wherein the host transceiver unit is connected with the host; a processor connected with the transceiver and configured to process data from the host and the human interface device, and a power circuit connected with the processor and configured to regulate the power usage of the human interface device, wherein the power circuit includes a battery, a computer readable media having instructions thereon, wherein the instructions include routines for monitoring the operational state of the human interface device, and routines for controlling the operation of the human interface device using the operational state of the human interface device to maximize the useful life of the batteries.

Power management for wireless peripheral device with force feedback

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.
