APPARATUS AND METHOD TO ESTIMATE A POSITION OF A TERMINAL IN A FACILITY HAVING MULTIPLE FLOORS
An apparatus determines a plurality of candidate position groups each indicating an trajectory of estimated terminal positions on a candidate floor selected from among multiple floors, wherein the trajectory of estimated terminal positions on the candidate floor is estimated based on positions of base stations installed on the candidate floor and intensities of radio waves that have been transmitted by a terminal at time points and detected by the base stations. The apparatus identifies, from among the candidate floors selected from the multiple floors, a target floor on which the terminal actually exists, based on the trajectories of estimated terminal positions for the determined plurality of candidate position groups and a movement requirement that defines a condition of actual movement of the terminal on each of the candidate floors.
DETERMINING POSITION OF A DEVICE IN THREE-DIMENSIONAL SPACE AND CORRESPONDING CALIBRATION TECHNIQUES
Positioning mobile devices in a three-dimensional space includes receiving multiple traces, each trace corresponding to a sequence of atmospheric pressure readings from a respective mobile device, receiving indications of signals received by the mobile devices from signal sources concurrently with the atmospheric pressure readings, generate similarity metrics for the multiple traces using the indications of other signals received by the mobile devices, the similarity metrics being indicative of associations between the signal sources and the atmospheric pressure readings, and determine estimated changes in elevation over time for the multiple traces using the generated similarity metrics.
ADJUSTING A BUILDING SERVICE SYSTEM
The invention relates to adjusting at least one of installed building service sensors (10) of a building service system. A sensor coverage area of at least one sensor (10) is adjusted based on information on a position of the installed sensor (10) relative to at least one other sensor (10). For example, to determine the position of the sensor (10) relative to said at least one other sensor (10), each sensor (10) establishes a wireless communication between said sensor (10) and at least one other sensor (10) via a wireless communication means (34) of the sensor (10). For example, information on the positions of the installed sensors (10) is used to assign to each sensor (10) at least one of installed building service supply devices (12) of the system.

Intelligent security via accurate mobile device location sensing
Described is intelligent security based on the detection of the presence of mobile devices within a defined region, determined via accurate mobile device location sensing, e.g., within on the order of one meter. Upon detection of the presence of a mobile device within a defined region via mobile device millimeter wave-based position sensing, an identity associated with the mobile device is obtained. If the identity associated with the mobile device is not a trusted identity, action can be taken based on the presence of the identity within the defined region. The intelligent security can be implemented within an application program of a registered user's mobile device and/or a security system, such as a commercially available security system with alarm monitoring services. Various criteria can determine the action(s) to take, including by which region (if more than one), time of day, identity trust level, duration of presence, and the like.

Information processing device, mobile terminal, and information processing method
There is provided an information processing device, a mobile terminal, and an information processing method capable of executing information processing more reliably. Bluetooth Low Energy (BLE) is used to transmit a beacon that is a signal for detecting a mobile terminal within a communication range of the BLE. Ultra Wide Band (UWB) is used to perform ranging processing of measuring at least a distance from the mobile terminal detected using the beacon to a UWB gate unit provided with a fare calculation zone in which fare payment processing is performed with the mobile terminal. Then, when it is detected that the mobile terminal enters the fare calculation zone on the basis of a result of the ranging processing using UWB, data communication for payment using UWB is performed between the UWB gate unit and the mobile terminal. The present technology can be applied to, for example, a touchless fare payment system using BLE and UWB.
DYNAMIC SEGMENTATION AND OCCUPANCY SCORING IN EDGE ENVIRONMENTS WITH MOBILE DEVICES FOR REAL-TIME DECISION MAKING
Occupancy aware decision-making is disclosed. Positions of entities in an environment are determined. Stationary entities are used as markers to segment the environment. Positions of non-stationary entities are used to determine an occupancy score for each of the segments. Decision making operations, such as pathfinding for mobile entities, can be performed using the occupancy scores of the segments. The occupancy scores and segmentation adapt to changes in the environment.
