Patent ID: 8238407

Claim:
A system for wireless transfer of data, said system comprising: a host transceiver unit configured to be connected with a host device, and configured to wirelessly exchange data with a human interface device; a human interface device configured to wirelessly exchange data with the host transceiver unit; and computer readable media having instructions thereon, said instructions comprising routines for synchronizing said host transceiver unit and said human interface device for wirelessly exchanging data between said host transceiver unit and said human interface device at a spread spectrum modulation pattern which is determined by said host transceiver unit after said host transceiver unit and said human interface device have acknowledged each other's presence, said instructions further providing a marriage ID, said marriage ID being used by both said host transceiver unit and said human interface device to calculate said spread spectrum modulation pattern, such that subsequent hops in said spread spectrum modulation pattern are not transmitted, but are calculated independently by said host transceiver unit and human interface device, wherein said human interface device is configured to broadcast at one of a plurality of different device spread spectrum modulation patterns, each of which is a function of a device communication state, the device communication states including at least a scan state and connected state.
