This invention relates to devices, systems, and methods for location tracking and proximity detection. The invention uses transmitting devices with more than one transmission range. In various embodiments, the invention uses a primary device to transmit a near-range signal and a medium-range signal. In other embodiments, the invention uses a secondary device to receive these signals and, on the basis of the received signals, generate alerts, transmit signals, or do both. In further embodiments, the invention uses another device to provide the location of the secondary device, the primary device, or both devices. This invention may be used for contact tracing, hand hygiene compliance monitoring, and location tracking.

A system of multi-modal transmission of packetized data in a voice activated data packet based computer network environment is provided. A natural language processor component can parse an input audio signal to identify a request and a trigger keyword. Based on the input audio signal, a direct action application programming interface can generate a first action data structure, and a content selector component can select a content item. An interface management component can identify first and second candidate interfaces, and respective resource utilization values. The interface management component can select, based on the resource utilization values, the first candidate interface to present the content item. The interface management component can provide the first action data structure to the client computing device for rendering as audio output, and can transmit the content item converted for a first modality to deliver the content item for rendering from the selected interface.

A user device, UE, for a wireless communication system is described. The wireless communication system includes a plurality of user devices, UEs. The UE is to communicate with one or more further UEs using a sidelink, SL. One or more location information elements describe a location or position of a UE, wherein the location information element includes a first part and a second part, wherein, for locations or positions within a certain area, the first part of the location information element is one of a set of fixed first parts and the second part of the location information element varies dependent on the actual or exact location or position of the UE. When being in the certain area, the UE is to receive from the further UE, e.g., using sidelink control information, SCI, position information of the further UE, the position information including some or all of the second part of the location information element of the further UE, and obtain the location or position of the further UE by combining the one of the set of fixed first parts with the position information which is received from the further UE, wherein, in case the set of fixed first parts includes more than one fixed first part, the UE is to select the one of the set of fixed first parts using the position information which is received from the further UE.

A system comprising: a transmitting device configured to transmit, in at least one plane, a plurality of directional signals each covering an angular sector, wherein every adjacent pair of said angular sectors overlaps partially to create a logical sector, and wherein each of said plurality of directional signals encodes at least an indication regarding each said logical sector associated therewith; and a client device comprising program instructions executable by at least one hardware processor to: cause the client device to receive at least some of said plurality of directional signals, calculate a signal strength level (RSL) value for each of said received directional signals, and determine that said client device is located within a said logical sector, when two highest said RSL values (i) are related to two said directional signals associated with said logical sector, and (ii) are within a specified value range of each other.

This position detection system comprises a mobile station that transmits a beacon signal, a plurality of fixed stations that receive the beacon signal, and a position analysis device that acquires position information for the mobile station by estimating the position of the mobile station from the reception intensities of the beacon signal at each fixed station. The mobile station includes a movement detection unit (acceleration sensor, geomagnetic sensor, etc.) that determines when movement has stopped. While the movement of the mobile station has stopped, the position analysis device stops estimating the position of the mobile station and keeps the position information at a fixed position.

A system and method of tracking and monitoring the location of devices for preventing theft and unauthorized use; and the tracking and monitoring of worn devices with sensors for monitoring persons requiring assistance and/or supervision.
