摘要： A vehicle and an electronic key perform wireless communication conforming to Bluetooth using at least a first electromagnetic wave of a first wavelength, estimate a second distance based on at least electric field strength and/or electromagnetic wave arrival time of the first electromagnetic wave of the first wavelength, and do not perform distance estimation based on at least a phase difference between a second electromagnetic wave of a second wavelength and a third electromagnetic wave of a third wavelength until a condition that the estimated second distance is smaller than a second distance threshold and a change in the estimated second distance is greater than a predetermined change is satisfied.

摘要： A system for monitoring and controlling a manufacturing environment is disclosed. Aspects discussed include beacons broadcasting identifying information for aspects of the manufacturing environment such as workstations, manufactured items, machines, equipment, and people. The identifying information may be used to generate reports about the operation of these and possibly other aspects, as well as provide control options for changing the manufacturing environment. Employees may move about the environment to visually monitor activities taking place, while the system may automatically query for additional information about the tools, equipment, people encountered in the environment. Control options for changing aspects of the manufacturing processes may also be automatically displayed as well.

摘要： A method includes estimating distances between a user device and an access point based on a series of FTM ranging bursts exchanged between the user device and the access point. The method also includes calculating a variance of the estimated distances and in response to determining that the variance exceeds a threshold, instructing the user device to perform an action that reduces the variance. Other embodiments include a device that performs this method.

摘要： A target distance estimation device includes: a multipath composite wave signal generation unit that generates a multipath composite wave signal that is a simulation signal of a composite wave of a direct wave and a multipath wave received by a reception antenna in a case where a provisional target distance, which is a provisional target distance from a radio source to a radio wave detection device, is set; and a target distance estimation unit that estimates a target distance from the radio wave detection device to the radio source on the basis of a correlation between the reception signals and the multipath composite wave signal generated by the multipath composite wave signal generation unit.

摘要： Each transmitter transmits an ID signal that is a wireless signal including an ID of the transmitter. A user terminal includes a wireless signal receiver to acquire an electric field strength at reception of the ID signal, a position acquirer to acquire, for combinations of three transmitters selected from four or more transmitters, estimated positions of the user terminal, each of the estimated positions being acquired based on (i) electric field strengths acquired for the three transmitters of each combination and (ii) installation positions previously stored of the three transmitters of each combination, a position specifier to specify a position of the user terminal based on the estimated positions acquired for each combination, and a facility device controller to control a facility device based on the specified position.

摘要： In various embodiments, a system for identifying a vertical height of a user equipment using network-side components, instead of device-side components, is described. The system may include a fixed antenna of a node and a processor. The antenna sends a first beam having a first set of beam characteristics and receives a first signal strength indication from the user equipment based upon the first beam. The antenna then sends a second beam having a second set of beam characteristic and receives a second signal strength indication from the user equipment based upon the second beam. The processor may then analyze the first signal strength and the second signal strength to determine the vertical height of the user equipment, such as by a trigonometric calculation based upon an inclination of the beams and various known distances.

摘要： A position and tracking system for radio-based localization in an operating room, includes a receiver, a mobile cart, a processor, and a memory coupled to the processor. The mobile cart includes a robotic arm and a transmitter in operable communication with the receiver. The memory has instructions stored thereon which, when executed by the processor, cause the system to receive, from the transmitter, a signal including a position of the mobile carts in a 3D space based on the signal communicated by the transmitter and determine a spatial pose of the mobile carts based on the received signal.
