Methods and apparatus for verifying respective positions of Nodes based upon ultrawideband wireless communications between nodes included in an array. Values for variables derived from multiple wireless transmissions between the nodes are aggregated, and a position of a particular node may be determined based upon multiple data sets generated by multiple communications of disparate Nodes. Data is transmitted to a smart device based upon a position of a particular node and a direction of interest. In addition, the presence of an obstacle to wireless communication between some nodes may be derived from the data sets. A user interface may provide a pictorial view of positions of all or some Nodes in an array, as well as a perceived obstruction.

A system and method for identifying a type of vehicle occupant based on locations of a portable device that include receiving a plurality of communication signals from the portable device and evaluating received signal strength measurements of the plurality of communication signals to determine a tracking pattern that includes a tracked path of the portable device as a user approaches a vehicle, enters the vehicle, and is seated within a particular seat of the vehicle. The system and method also include identifying the user as a driver of the vehicle or a non-driving occupant of the vehicle based on the tracking pattern and controlling at least one vehicle system by executing vehicle settings associated with the driver of the vehicle and the non-driving occupant of the vehicle based on identifying the user as the driver of the vehicle or the non-driving occupant of the vehicle.

A method for determining the location of mobile devices, comprising providing at least one mobile device and at least two access points distributed over two or more locations; noting the identity of access points the device is connected to over time; noting transitions between access points a device is connected to and identifying two or more access points as belonging to the same location if the mobile device transitions between connecting to said access points within a certain time period; allocating a first location to a group of access points to which a device transitions within said certain period of time and a second or further location to access points to which a device does not transition to from the first set of access points within said certain period of time; thereby associating groups of one or more access points with one or more locations, and determining the location of the device when it is subsequently connected to one of the located access points.

A method for locating an element which can be transported by aircraft includes, for a first position of an aircraft: a) transmitting, from an antenna located in the aircraft, a first message intended for the transportable element; b) receiving, on the antenna, a second message transmitted by the transportable element upon receipt of the first message; c) obtaining a travel time of the first and second messages; d) determining a distance from the travel times; e) determining that the element is inside the aircraft if the distance is less than a value and that the element is outside the aircraft if the distance is greater than the value.

Provided are a positioning method, apparatus and system, a layout method for a positioning system and a storage medium. A plurality of labels is laid with preset positioning precision in an area to be positioned, where each label among the plurality of labels carries label information, where the label information corresponds to position information of a position of the each label. A position acquisition device reads first label information on a label at a distance not greater than the preset positioning precision from the position acquisition device; and the position acquisition device determines first position information of the position acquisition device according to the first label information.

An electronic patient monitoring system and method of operation that includes one or more generally non-metal, tamper-resistant patient identification and monitoring devices, an observer transmitter/receiver device configured to receive and detect one or more beacon signals that exceed a predetermined threshold from at least one of the not easily removable patient identification and monitoring devices, set a time to hold open a window for a response on the transmitter/receiver device, and send a request for information to the observer with the transmitter/receiver device, and a central computer system. Each of the transmitter/receiver device and the central computer system, including, at least, a computer processor, communications components and system software to communicate with the observer transmitter/receiver device at specified/predetermined time intervals to receive observer- and patient-specific information.

A system for simultaneous localization and mapping (SLAM) of an object in an area includes: at least one base station; at least one user equipment (UE) configured to communicate with the at least one base station; and at least one object to be localized. Each object of the at least one object comprises an identification (ID) tag. The at least one UE and/or the at least one base station is configured to localize a respective object via a respective ID tag. The at least one base station is configured to localize the at least one UE in the area based on 5G communication. The at least one UE is configured to localize the object based on the respective ID tag and configured to transmit a relative position of the respective object with respect to the at least one UE to the at least one base station.

One or more processors obtain a first radio environment signature associated with an aerial vehicle (AV) and a second radio environment signature associated with a computing device. Responsive to determining that the first radio environment signature and the second radio environment signature satisfy a similarity criteria, the one or more processors generate a validation data object verifying one or more of (i) that a location of the AV substantially corresponds to a location of the computing device at a time associated with at least one of the first radio environment signature or the second radio environment signature, (ii) a AV delivery associated with the AV and the computing device, or (iii) a AV pickup associated with the AV and the computing device. The one or more processors store or provide validation information based on the validation data object.

A method for locating wireless tags is described. A signal including a RoomID generated by a transceiver is received by a wireless tag. The RoomID identifies a room corresponding to the transceiver and the wireless tag receives the signal asynchronously without being synchronized with the transceiver. A tracking packet including the RoomID and an identifier of the wireless tag is broadcasted by the wireless tag. The tracking packet is received by an access point which provides the tracking packet to a localization system that determines a location of the wireless tag based on the RoomID.
