Abstract: A system and method for determining a position or a movable device is disclosed. The present system utilizes a movable device equipped with a locator device that has an antenna array such that it may determine the angle of arrival of a plurality of incoming beacon signals. In certain embodiments, the movable device is also able to measure its distance travelled. By knowing its distance moved and the angle of arrival from each beacon, the locator device is able to calculate its position as well as the position of each beacon. This procedure may be executed at regular intervals so that the movable device accurately determines its position.

IPC: H04W56/00
Abstract: A system and method of synchronizing the clocks between two connected Bluetooth devices is disclosed. The two devices exchange packets that contain a timestamp that is indicative of the time that each device received a packet from the other device. By exchanging this information, each device may determine the offset between its internal clock and the internal clock of the other device. Once clock synchronization is achieved, the central device may transmit packets to the peripheral requesting that particular actions be taken at specific times.
