A local positioning system may include a reader assembly and a data processing assembly. The reader assembly may be configured to read tag data from at least one wireless communication tag of a plurality of wireless communication tags disposed in spaced-apart fixed positions relative to a structure extending along an expanse when the reader assembly is disposed in the expanse proximate to the at least one wireless communication tag. The reader assembly may also generate a communication-tag signal representative of the read tag data. A data processing assembly may be configured to access a mapping of the plurality of wireless communication tags relative to the structure. The data processing assembly may be further configured to determine a location of the reader assembly based on the read tag data and the mapping of the plurality of wireless communication tags relative to the structure.

Systems and methods for navigating an aerial vehicle are provided. One example aspect of the present disclosure is directed to a method for navigating an aircraft. The method includes receiving, by one or more processors, one or more first geographic coordinates via an interface configured to receive geographic coordinates from a satellite transmission. The method includes receiving, by the one or more processors, one or more second geographic coordinates via an interface configured to receive geographic coordinates from a ground transmission. The method includes determining, by the one or more processors, that the one or more first geographic coordinates and the one or more second geographic coordinates are inconsistent. The method includes updating, by the one or more processors, a flight plan using the one or more second geographic coordinates when the one or more first geographic coordinates are inconsistent with the one or more second geographic coordinates.

One or more surfaces within a facility are equipped with devices having several segments, each segment with an antenna. Segments may be grouped together into a cluster. Each segment within a cluster is associated with a particular timeslot. A transmitter at the device transmits on a specific frequency. During the particular timeslot for that segment, a signal at the specific frequency is transmitted and radiated from the antenna for that segment. An object electromagnetically couples to one or more antennas of the device, acting as a signal path for the signal. A receiver in a second segment detects the signal, and information about the timeslot for the signal and relative signal strength is generated. By using this information, a location and path of the object may be determined. Receivers in shelves may also be used to facilitate disambiguation of one user from another when interacting with items on those shelves.

The present invention relates to a wireless power transmission method in a wireless charging system supporting electromagnetic resonance and a device therefor. According to one embodiment of the present invention, a wireless power transmission method in a wireless power transmitter wirelessly supplying power to a wireless power receiver through a resonance phenomenon can comprise the steps of: entering a configuration state according to the application of power and performing booting; generating a random first standby offset when the booting is completed; and entering a power saving state at a point in time determined on the basis of the first standby offset, so as to initiate a beacon sequence. Therefore, the present invention has an advantage of enabling power loss caused by cross connection and device damage caused by heat generation in the wireless charging system to be minimized.
