A traffic control system is described that comprises a transceiver configured to receive a first signal comprising location data indicating a location of an unmanned vehicle (UV). The traffic control system further comprises a processor configured to determine a location of a second vehicle and determine a course of the second vehicle. The processor is further configured to cause, based on determining the location of the second vehicle and the course of the second vehicle, the transceiver to transmit a second signal to the UV directing the UV to avoid the course of the second vehicle.

The safe operation assistance device 200 includes: a connecting destination detecting section 259 that detects and manages a connection state between the safe operation assistance device 200 and a connecting destination device; a unique information setting section 251 that sets unique information identifying a vehicle type of an own vehicle according to the connecting destination device; a positional information acquisition section 257 that acquires positional information of the own vehicle; an own vehicle information management section 252 that manages the positional information and the unique information of the own vehicle; an inter-vehicle communication section 255 that transmits the own vehicle information to other vehicle and acquires other vehicle information; and a risk determination section 254 that determines presence or absence of a collision risk between the own vehicle and the other vehicle using the own vehicle information and the other vehicle information.

Systems and methods for transferring electric power to an aircraft during flight. Power transfer to the receiver aircraft is effected by means of a donor aircraft using a wired electrical connection. The method for transferring electric power includes: establishing an electrical connection between a receiver aircraft and a donor aircraft during flight; and transferring electric power from the donor aircraft to the receiver aircraft via the electrical connection. In one embodiment, electric power is transferred by way of a power cable deployed by the donor aircraft, a drogue attached to a trailing end of the power cable, and a probe mounted to the fuselage of the receiver aircraft, The probe and drogue are configured to form an electrical connection when fully engaged.

In an aspect, a UE (e.g., PUE or VUE) performs one or more sidelink positioning measurements on a first sidelink positioning signal between PUE and a VUE. The UE transmits measurement data based on the one or more sidelink positioning measurements to a RSU. The RSU receives the measurement data and determines a positioning estimate for the PUE. The RSU transmits the positioning estimate to the PUE, at least one VUE, or a combination thereof.

An apparatus comprising a transceiver, an antenna and a processor. The transceiver may be configured to send/receive data messages to/from a plurality of vehicles. The antenna may be configured to receive signals from GNSS satellites. The processor may be configured to (i) determine a first region based on relative coordinates calculated using the data messages, (ii) determine a second region calculated using the signals received from the GNSS satellites, (iii) determine whether a pre-determined amount of the first region to the second region overlap and (iv) increase a confidence level of a positional accuracy of the plurality of vehicles if the pre-determined amount of the first region and the second region overlap. One of the vehicles implements one or more automatic responses based on the confidence level of the positional accuracy.

Various methods and apparatus relating to synchronizing location information between two or more devices are described. In some embodiments, the devices are both configured to generate GNSS receiver data that is synchronized to achieve greater location accuracy. In some embodiments, the GNSS receiver data can be weighted when one set of GNSS receiver data is known to have a higher accuracy than another set of GNSS receiver data.

Presented are intelligent electronic footwear and apparel with controller-automated features, methods for making/operating such footwear and apparel, and control systems for executing automated features of such footwear and apparel. A method for operating an intelligent electronic shoe (IES) includes receiving, e.g., via a controller through a wireless communications device from a GPS satellite service, location data of a user. The controller also receives, e.g., from a backend server-class computer or other remote computing node, location data for a target object or site, such as a virtual shoe hidden at a virtual spot. The controller retrieves or predicts path plan data including a derived route for traversing from the user's location to the target's location within a geographic area. The controller then transmits command signals to a navigation alert system mounted to the IES's shoe structure to output visual, audio, and/or tactile cues that guide the user along the derived route.

To measure the distance between the devices with higher accuracy.

There is provided a control device comprising a control section configured to control a ranging process of measuring a distance between communication devices, wherein the control section causes the ranging process to be executed more than once, and controls a subsequent process on a basis of a representative value of a plurality of ranging values that have been acquired, the subsequent process being a process using the representative value.

Methods and systems provide for technology to identify a trigger event. In response to the trigger event, the technology executes a triangulation process that includes a transmission and reception of triangulation signals between the plurality of ECUs to identify current positions of the plurality of ECUs. A first current position among the current positions is associated with a first ECU among the plurality of ECUs. The technology conducts an identification that the first current position is different from a first recorded position of the first ECU. In response to the identification that the first current position is different from the first recorded position, the technology identifies an adjustment factor based on the first current position. The technology calibrates one or more of the plurality of ECUs based on the adjustment factor to adjust control of at least one system of a plurality of systems of the vehicle.

A system for assisting drivers and riders to find each other in a ride-hailing service is provided. A driver device may communicate with a rider device. The driver device may receive GPS coordinates of the rider device such that the relative location of the rider device can be determined via GPS. In response to the rider device being within a threshold distance from driver device, the rider device and driver device can connect via Wi-Fi to share data to improve the locational ability of the system. At least one processor can receive Wi-Fi data packets from the rider device, measure and extract channel state information (CSI) from the Wi-Fi data packets, execute an angle of arrival (AoA) application to determine the angle of arrival based on the CSI, and display a location of the rider based on the determined angle of arrival from the CSI.
