A method performed by a first device for locating a medical device within a medical facility includes determining, by the first device, that a second device is located in a same room as the first device, based on a first signal communicated between the first device and the second device; determining, by the first device, a distance to the at least one second device, based on a second signal communicated between the first device and the second device; and establishing communication with the second device. A device, a wireless stationary node, a location determining system and method, and a patient support apparatus are also described.

The present disclosure describes a facility (e.g., home) control system using a community of components (e.g., comprising one or more sensors, emitters and/or transceivers) that are configured to locate at least a portion of its members and control one or more devices of the facility.

Disclosed are indoor positioning methods, apparatuses, electronic device and computer readable storage medium. The indoor positioning method includes: obtaining state data of a mobile terminal; based on a pre-trained position classification model, determining a position classification of the mobile terminal according to the state data of the mobile terminal; when the position classification of the mobile terminal is an anchor point position, taking the mobile terminal as a beacon terminal and sending an anchor point position broadcast instruction to the beacon terminal to enable the beacon terminal to broadcast the anchor point position. In the technical solution, a mobile terminal meeting anchor point requirements is taken as a beacon terminal to provide convenient positioning services, so as to avoid deployment and maintenance of a large number of beacons, hardware of routers, and related mapping relationship, thus greatly reducing investment costs and facilitating promotion of use.

Apparatus for displaying information associated with a wireless location node via a user interface based upon electromagnetic radiation received from a radio target area. More specifically, the present invention relates to methods and systems for receiving electromagnetic radiation received from a radio target area, and presenting digital content in a user interactive interface.

An Agent supportable device for determining a direction of an item of interest. The Agent supportable device includes an antenna configured to communicate with the reference transceiver associated with the item of interest. A receiver in the Agent supportable device is in logical communication with the antenna. A transmitter is also in logical communication with the antenna. A digital storage contains software executable upon demand via a processor in logical communication with the digital storage. The processor is operative via execution of the software to cause the apparatus to display a user interface on a visual display that includes an arrow indicating a direction of the item of interest in relation to the apparatus and a distance between the apparatus and the item of interest.

A method of associating data with a physical location comprises receiving, by at least two receiver antennae, a radiofrequency (RF) signal transmitted by a mobile device, the RF signal conveying data collected by the mobile device from an external source; calculating, for each of the at least two receiver antennae, a phase of the RF signal received by each receiver antennae; calculating, based on the calculated phases, a physical location from where the mobile device transmitted the RF signal; and associating the data conveyed by the RF signal and the external source from which the data were collected with the calculated physical location from where the mobile device transmitted the RF signal.

A transmitter which emits at least two electromagnetic fields. An amplitude of each of the at least two electromagnetic fields has an anisotropy in one plane. An angular arrangement of the receiver relative to the transmitter is determined based on the amplitude of the at least two electromagnetic fields at the position of a receiver.

A system for determining location information for a wireless device is described. The system includes a UE, a LE and multiple LMUs. The LE sends, to the LMUs, reception instructions with characteristics of the signal transmission from the UE and each LMU receives, from the LE, the reception instructions. The UE sends a signal transmission. Each LMU receives the transmitted signal from the UE, determines locating information based at least in part of the received signal and sends the locating information to the LE. The LE receives the locating information regarding the transmitted signal and determines a location of the UE based at least in part on the received locating information. Methods, apparatus and computer readable media are also described.

Accurate position capability can be quickly provided using a Wireless Local Area Network (WLAN). When associated with a WLAN, a wireless device can quickly determine its relative and/or coordinate position based on information provided by an access point in the WLAN. Before a wireless device disassociates with the access point, the WLAN can periodically provide time, location, and decoded GPS data to the wireless device. In this manner, the wireless device can significantly reduce the time to acquire the necessary GPS satellite data (i.e. on the order if seconds instead of minutes) to determine its coordinate position.
