A method for localizing a user device using a Time of Flight (ToF) antenna array disposed on a vehicle, the method includes determining, via a ToF localization controller, that the user device is less than a threshold distance from the vehicle, determining an angle of arrival via the ToF localization controller and the ToF antenna array, and generating an unlock signal that unlocks a vehicle door responsive to determining that the user device is less than the threshold distance from the vehicle door.

At least a method for determining risk behavior of a driver is described. While a vehicle is being driven, data is obtained related to the position and movement of a wireless communications device. The data may indicate the type of behavior exhibited by the driver while the vehicle is being driven.

A system for location of animals and/or objects in an environment includes a signal processing and signal generation system consisting of electromagnetic tags on animals (or other objects) in an environment (typically a three dimension outdoor natural environment) where the animals or objects are physically present at arbitrary locations, and an electro-magnetic signal generating, signal receiving, and signal processing system that can move through or in relation to the environment. The system can compute the location and identity of the animals or objects based on signals received from their associated tags, including the calculated location of the ID tags, which function as “Reader-Locators.” The calculated location is enhanced by information about the environment provided by maps, satellite photos, GPS, GIS and/or other data specific to the probability of the location of the animals or objects within certain regions of the environment. The system includes a physical and electromagnetic modeling operation that is interactive with the environmental information derived from the actual environment, either historically or in “real-time” as the monitoring process occurs.

A method for managing transmission of a location of a first geo-tag capable of communicating with a second geo-tag, the tags being classified in several respective categories, the first tag being associated with a first category. The method includes implementing following steps in the first tag: a. detecting a proximity between the first geo-tag and the second geo-tag; b. obtaining the category associated with the second tag; c. transmitting, to the second tag, a request to transfer management of the transmission of the location of the first tag, if the obtained category belongs to a second tag category.

A system and method for obtaining location data for a portable device relative to an object. The system and method may include an object device disposed in a fixed position relative to the object, the object device having an antenna configured to communicate wirelessly via UWB with the portable device via a communication link. The system may include a control system, such as a robot and/or a remote controller, configured to obtain one or more samples pertaining to communications between the portable device and the object device.

At least a method for determining risk behavior of a driver is described. While a vehicle is being driven, data is obtained related to the position and movement of a wireless communications device. The data may indicate the type of behavior exhibited by the driver while the vehicle is being driven.

A system includes a first-vehicle processor configured to receive a signal broadcast from a second vehicle. The processor is also configured to determine a distance between a first transceiver, receiving the signal, and a second transceiver, transmitting the signal. The processor is further configured to determine second vehicle dimensions. Also, the processor is configured to digitally map a second vehicle perimeter around a second transceiver location, determined based on the distance and alert a first vehicle driver of a likely overlap condition of the second vehicle perimeter and a first vehicle perimeter.

There is provided a method performed by a system for obtaining a relative location of an anchor-free UWB-based node. The method includes obtaining relative distances between a plurality of nodes based on UWB sensor values between the nodes, constructing a relative coordinate system having a center node of the plurality of nodes as a base, and calculating coordinate values of other nodes in the relative coordinate system. The constructing of the relative coordinate system having the center node of the plurality of nodes as a base includes constructing the relative coordinate system based on a relative distance between the center node and another node and absolute values of y axis values.

Locating systems and methods for wireless seat belt monitoring in vehicles with removable or reconfigurable seats are provided herein. An example remote transceiver can be centrally located on a seat that is configured to be rearranged within a vehicle. The remote transceiver can include a processor and memory for storing instructions that include a unique code identifying the remote transceiver. The processor executes the instructions to receive low power signals from transmitters within an interior of the vehicle, determine received signal strength values of the low power signals. The received signal strength values are used by the vehicle receiver to determine a location of the remote transceiver within the vehicle.

A method of controlling a household appliance including receiving a device connection request signal through ultra wideband (UWB) communication from a user terminal, obtaining location information of the user terminal based on the received device connection request signal, establishing a UWB communication channel between the household appliance and the user terminal based on the obtained location information. The method includes receiving network access information to access a network from the user terminal through the established UWB communication channel, and establishing a network connection for the household appliance to access the network based on the received network access information.
