Abstract: A wireless communications system includes an accessory device and multiple host devices. A host device pairs wirelessly with an accessory device using a unique link key, detects a primary trigger event and responds by transferring automatically its pairing with the accessory device to a second host device while all devices remain within wireless range of each other. The pairing transfer involves communicating the link key to the second host device, unpairing the accessory device from the first host device, and establishing a wireless pairing of the accessory device to the second host device. The primary trigger event can involve establishing a ported connection between host devices. A secondary trigger event results in the first host device automatically reclaiming its pairing with the accessory device. An accessory device can also select and pair with one of multiple host devices in response to a specific user gesture detected by the accessory device.

Abstract: An apparatus and method is disclosed for determining the position of a user interface mouse using time of arrival measurements. A transmitter transmits a signal to an array of receivers that are spatially separated from one another. The time difference of arrival for is found for each receiver relative to a predetermined reference receiver. Using the time difference of arrival (TDOA) of each receiver, the location in 3-dimensional space of each receiver, and the speed of sound the position of the transmitter in 3-dimensional space relative to the reference receiver may be found.
