A position detection system 1 identifies position information on the basis of a position signal received from a storage medium 30P disposed in a placement area where a target item is placed, identifies item information on the basis of an item signal received from a storage medium 30Q attached to the target item, and associates the position information with the item information and stores the associated information when the item signal is received during a period of time that starts from a time at which the position information is identified and that does not exceed a predetermined length of time.

An apparatus, method and computer program is described comprising: receiving downlink positioning signals from each of a plurality of communication nodes of a mobile communication system at a user device of the mobile communication system, wherein each downlink positioning signal is received from a downlink beam direction for the respective communication node; determining an angle of arrival and/or a time of arrival for each of the received downlink positioning signals; and determining an uplink positioning signal beam configuration based, at least in part, on the determined angle of arrival and/or the determined time of arrival for said received downlink positioning signals.

An example system can include a first antenna having a first orientation, a second antenna having a second orientation and a control system communicating with the first antenna and the second antenna. The control system performs operations which can include determining a pathway of a satellite, comparing the pathway to a first radiation pattern of the first antenna and a second radiation pattern of the second antenna, wherein the first antenna and the second antenna are each positioned such that a first keyhole of the first antenna does not overlap a second keyhole of the second antenna, to yield a comparison and selecting, based on the comparison, one of the first antenna or the second antenna to communicate with the satellite along the pathway.

This document presents a system to identify patterns of life associated with the users of radio frequency emitting devices radiating within a monitored volume. These recurring commonalities in human activity can be derived from collected data and subsequent analytics that provide intelligence about those emitters and associated humans present within the monitored volume. The Freya system provides unique identifiers for detected emitters; insights into the current network relationships between emitters, past and current; human relational networks within the monitored volume; and can identify previous emitter locations prior to detection by the Freya system. These patterns of life provide a foundation for predicting interactions between humans associated with emitters active on the Internet of Things (IoT). This capability provides enhanced security capabilities as required by authorities for sensitive venues and events.

The application relates to a method and a system for determining the position of a fitted formwork, including: emitting a locating signal from the fitted formwork; receiving the emitted locating signal using a receiver at at least one reference point; determining a distance between the fitted formwork and the at least one reference point on the basis of the locating signal received; determining a fitting position, compatible with the distance determined, of the fitted formwork on at least one existing formwork; and storing the fitting position determined as the position of the fitted formwork.

A tire mounting position detection system measures a first signal strength which is the strength of a radio signal received by a first receiver (R1) for each transmitter, measures a second signal strength which is the strength of the radio signal received by a second receiver (R2) for each transmitter, and calculates an strength ratio which is a ratio using the first signal strength and the second signal strength for each transmitter. The tire mounting position detection system detects a wheel position where a tire equipped with a transmitter is mounted on the basis of the first signal strength, the second signal strength and a strength ratio for each transmitter.

A method for detecting a change in location of at least one wheel of a motor vehicle, the vehicle having at least one central processing unit, one wheel unit which includes an electronic assembly of sensors and which is mounted on the wheel, and one bidirectional communications assembly. The method notably includes a first comparison step, during which a first evaluation pattern is compared with a first reference pattern to determine whether the location of the wheel has changed, the patterns being representative of the effective location of the wheel unit in the motor vehicle.

Systems and methods of using satellite signal strength to determine indoor/outdoor transition points for places are disclosed herein. In some example embodiments, a computer system accesses service data and sensor data for a plurality of requests for a transportation service associated with a place, with the service data comprising pick-up data indicating a pick-up location and drop-off data indicating a drop-off location, and the sensor data comprising satellite signals indicating a pick-up path or a drop-off path, with the satellite signals each having a corresponding signal strength. The computer system determines a transition geographic location for the place based on the signal strengths of the satellite signals.

A wireless communication device, WCD, transmits one or more uplink transmissions, obtains backscattering measurements for the one or more uplink transmissions, and reports the backscattering measurements to a wireless communication network. A network node in the wireless communication network receives the backscattering measurements, and estimates an environment of the WCD based on the backscattering measurements. The one or more uplink transmissions may for example include a sounding reference signal, SRS. The network node may for example schedule a transmission, select beamforming, or adapt a positioning reference signal configuration based on the estimated environment of the WCD. The network node may for example receive positioning measurements and estimate a position of the WCD based on the positioning measurements. The estimation of a position of the WCD and the estimation of an environment of the WCD may for example be performed jointly via simultaneous localization and mapping, SLAM.
