Embodiments disclosed herein may generate and transmit power waves that, as result of their physical waveform characteristics (e.g., frequency, amplitude, phase, gain, direction), converge at a predetermined location in a transmission field to generate a pocket of energy. Receivers associated with an electronic device being powered by the wireless charging system, may extract energy from these pockets of energy and then convert that energy into usable electric power for the electronic device associated with a receiver. The pockets of energy may manifest as a three-dimensional field (e.g., transmission field) where energy may be harvested by a receiver positioned within or nearby the pocket of energy.

Estimating one or more positions of a receiver using one or more anchor points. Systems and methods for estimating a position of a receiver using a particular anchor point may identify an area of interest that includes anchor points, identify the particular anchor point, and then use information about the particular anchor point to estimate the position of the receiver.

A method for tracking an object includes associating a beacon with a responder; transmitting a polling signal from the beacon to the responder; receiving a response from the responder; entering a low power state on the beacon for a predetermined duration; and transmitting an alert from the beacon responsive to a subsequent signal from the beacon failing to result in receiving a subsequent response from the responder. Embodiments also include a system in which the beacon and responder are configured to perform the described functions. In various embodiments, the duration during which the beacon remains in the low power state is predetermined based either on a default factory setting or a user adjustable setting.

A plurality of location beacons is deployed within a site that is divided into zones. A plurality of assets is distributed within the site, each asset having an asset beacon attached to it. A tag occasionally moving within the site continually locates its current zone by detecting short-range signals received from location beacons, and when detecting an asset beacon, the tag locates the respective asset within the current zone of the tag.
