A method of identifying item selection by a user, the method comprising: receiving signals at a receiver of a fixed terminal from a transmitter of a mobile terminal associated with the user, generating a signature at the receiver of the fixed terminal of the movement of the user based on changes in the signals received from the transmitter, matching the signature with prior stored movement information to determine the movement of the user, and identifying the item being selected by the user based on the determined movement of the user.

Systems and methods for localization and passive entry/passive start (PEPS) systems for vehicles are provided. A communication gateway in a vehicle configured to establish a Bluetooth low energy (BLE) communication connection with a portable device. Sensors are configured to measure signal information about a communication signal sent from the portable device. A localization module is configured to receive the signal information from the sensors and determine a location of the portable device based on the signal information. A passive entry/passive start (PEPS) system is configured to receive the location of the portable device from the localization module and perform a vehicle function including at least one of unlocking a door of the vehicle, unlocking a trunk of the vehicle, and allowing the vehicle to be started based on the location of the portable device. Each of the plurality of sensors are synchronized.

An augmented reality platform and method for use of the same are provided. In one embodiment, an array of locationing devices determine a perspective value of a physical object within a space based on visual-inertial odometry, radio wave positioning, and acoustic positioning. A server determines a decided value of the physical object based on a plurality of perspective values of the physical object received from the array of locationing devices. A digital map and digital library maintained by the server maintain the location of physical objects and spatial experiential objects in order to provide the spatial experiential object to an augmented reality device.

The present disclosure is directed to a traffic signal apparatus communication system and methods of communicating traffic information to vehicles using same. The traffic signal apparatus communication system includes a traffic signal apparatus for providing a message to a vehicle. The apparatus includes at least one spatially encoded marker, and the vehicle is configured to receive returns of a radar signal from the spatially-encoded marker. At least one controller of the vehicle is configured to determine the message encoded by the spatially-encoded marker based on the returns and to control the vehicle based on the message. The message may include a value indicating a time to a transition of a new state of the traffic signal apparatus, where the new state includes emission of light from one of a first light source, a second light source, or a third light source of the traffic signal apparatus.

A mobile robot is configured for operation in a commercial or industrial setting, such as an office building or retail store. The robot can patrol one or more routes within a building, and can detect violations of security policies by objects, building infrastructure and security systems, or individuals. In response to the detected violations, the robot can perform one or more security operations. The robot can include a removable fabric panel, enabling sensors within the robot body to capture signals that propagate through the fabric. In addition, the robot can scan RFID tags of objects within an area, for instance coupled to store inventory. Likewise, the robot can generate or update one or more semantic maps for use by the robot in navigating an area and for measuring compliance with security policies.

Disclosed are some examples of techniques for positioning of a user equipment (UE) using positioning reference signal (PRS). One or more units of messages may be communicated between an initiator UE and a responder UE. A unit of message may include a pre-PRS message, a PRS message and a post-PRS message. The pre-PRS message and the post-PRS message may be sent or received using a license spectrum. The PRS message may be sent or received using an unlicensed spectrum. The communication between the initiator UE and the responder UE may be initiated by the initiator UE identifying the responder UE from a plurality of UEs based on positioning properties of the responder UE. The positioning properties of the responder UE may include one or more of a direction, a velocity, a location confidence and a location of the responder UE.

A method of determining an integer ambiguity search space includes: obtaining, at an apparatus, a code phase measurement of a satellite vehicle signal comprising a pseudorandom noise code and a carrier signal; obtaining, at the apparatus, spatial information corresponding to a wireless terrestrial signal transferred between the apparatus and a terrestrial base station; determining, at the apparatus, a satellite positioning system carrier phase integer ambiguity search space based on the code phase measurement; and constraining a size of the satellite positioning system carrier phase integer ambiguity search space based on the spatial information.

Positioning of a user equipment (UE) is supported using reception points (RPs) that receive uplink sounding reference signals (SRS) from the UE. The RPs may measure signal strengths of received SRS that are used to determine path loss reference values that are provided to the UE for configurating subsequent SRS. The UE may report a plurality of RxTx time difference measurements with respect to a single PRS for the SRS transmitted to a plurality of RPs. The RPs may provide an Rx time for received SRS, which is used to generate a RxTx time different measurement for asymmetric round trip time (RTT) if the RP and TRP clocks are synchronized. The RPs may provide an RxRx time difference measurement for a time of reception of PRS and SRS if the RP and TRP clocks are synchronized. A location server determines a position of the UE using different positioning measurements.

A radar-based system for determining the local position of a vehicle uses markers with at least one radar-reflective element, as well as a radar system and vehicle controller. The radar system transmits radio waves, which are reflected by nearby objects, including the radar markers. The radar system receives the reflected radio waves and detects the unique radar signatures from the radar markers, as well as range, azimuth, and/or elevation dimensions of the vehicle with respect to the radar markers. The unique radar signatures and dimensions are communicated to the vehicle controller, which then determines the local position of the vehicle from the unique radar signatures and dimensions.

A method, which can be implemented by a control unit, for carrying out a localization of at least one vehicle by a vehicle-side control unit includes receiving measuring data from at least one sensor, ascertaining at least one marking from the measuring data, and associating the ascertained marking with a marking entered into a digital map for determining a position.
