Methods and apparatus for improving the provision of a procedure based upon automated determination of a location of agents and equipment during a procedure and quantifying conditions in an environment via automated sensors. The present invention provides apparatus and methods for wireless designation of a position of health care providers and equipment relative to each other based upon wireless communications amongst multiple wireless transceivers combined with ongoing monitoring of conditions present in a facility. The transceivers may be portions of nodes and nodes may form self-verifying arrays. A user interface may provide a augmented reality view of positions of all or some the providers and equipment and condition quantifying sensors.

A storage (23) stores floor information including a restriction position that a person is unable to access within a floor. A wireless signal receiver (21) receives a wireless signal transmitted by a transmission terminal (10). A distance and angle estimator (22) estimates a distance to the transmission terminal (10) and an angle of arrival of the wireless signal based on the wireless signal received by the wireless signal receiver (21). A location identifier (24) identifies a current location of a user within the floor based on the floor information stored in the storage (23). A communicator (25) transmits, to a control device, location information including the current location identified by the location identifier (24) for the control device to control an air conditioner.

A device for detecting and/or tracking a projectile has a receiving antenna, for receiving at least an electromagnetic signal emitted by at least one radar, at least one amplifier configured to amplify the electromagnetic signal received by the receiving antenna, and at least one emitting antenna. The emitting antenna is configured to return, at an output of the device, an amplified electromagnetic signal for calculating data indicative of the trajectory of the projectile based at least on the amplified electromagnetic signal. A system for detecting a projectile has a transmitting device mounted on the projectile, a radar configured to sense an electromagnetic signal produced and sent by the transmitting device. The signals emitted from the projectile are limited to the electromagnetic signal sent by the transmitting device, and a processing unit, configured to calculate data indicative of the trajectory of the projectile, based on the sensing of the electromagnetic signal.

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.

UE location determined by collecting and preprocessing signal data at a detector and sending extracted data to a remote locate server. The detector buffers samples from signals provided by receive channels, detects known reference signals from receive channels based on reference signal parameters, isolates symbols carrying the reference signal from frames, extracts data from symbols, and sends extracted data to locate server. The locate server receives the extracted data, estimates locate observables based on the extracted data and calculates the UE location based on the estimated locate observables, the reference signal parameters and the extracted data. The detector and/or the server may also generate correlation coefficients between reference signals carrying spectrum received from a serving cell and utilize the correlation coefficients to cancel a serving cell signal in symbols that include known in advance reference signals from the serving cell and one or more neighboring cells of the wireless system.

Methods, systems, and devices for wireless communications are described. A position of a user equipment (UE) may be determined when communications between the UE and a base station are routed through a relay node. For example, the UE 115 may determine whether communications are received from the base station or the relay node based on positioning assistance data that contains positioning-related information about different base stations and relay nodes in the system. The UE may then transmit a position metric based on this determination, where a location server uses this position metric for determining the location of the UE. Additionally or alternatively, the location server or base station may use the positioning assistance data to determine whether an uplink transmission is received directly from the UE or via the relay node and may generate a position metric that the location server uses for determining the location of the UE.

Systems, methods, and apparatus cause a first wireless device to transmit to a plurality of locator devices, an extended signal including a first segment and second segment. The first segment includes an indication for each of the plurality of locator devices to listen for a change in the extended signal from the first segment to the second segment. The second segment includes an indication for each of the plurality of locator devices to rotate through a plurality of antennas to receive the second segment via the plurality of antennas.

An ultra wideband (UWB) dynamic positioning method and a system thereof are provided. A target UWB device detecting step includes driving a host UWB device to detect whether a target UWB device or at least one first-order seeking UWB device is around the host UWB device, and then a detecting result is generated. A host UWB device operation deciding step includes deciding an operating mode of the host UWB device according to the detecting result. When the target UWB device is around the host UWB device, the operating mode includes calculating a moving direction from the host UWB device to the target UWB device. When there is the first-order seeking UWB device around the host UWB device without the target UWB device, the operating mode includes switching on the first-order seeking UWB device to enter a seeking mode.
