A locating system includes a tag with body that has a first button and a second button, a driver configured to determine a type of button press of at least one of the first button and the second button, and a control unit in communication with the driver. The control unit is configured to communicate the type of button press determined by the driver. The tag also includes a transmitter in communication with the control unit. At least one receiver is configured to selectively communicate with the transmitter. A controller is in communication with the at least one receiver. The controller is configured to determine a location of the tag within a predefined area based on information from the at least one receiver, correlate the type of button press from the tag with a message, and generate a notification to communicate the message.

Lighting devices with lighting means, transmitting device for transmitting an electromagnetic data signal and energy buffer for current supply of the transmitting device are to be protected from exhaustive discharge. Thereto, an activation device is provided, by which the transmitting device can be activated from an energy-saving mode, in which the transmitting device is switched off, into an operating mode, in which the transmitting device is switched on for operationally transmitting the electromagnetic data signal.

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.

An apparatus, including a personal monitoring device assigned to an individual, which includes a database, global positioning device, first processor, and RFID tag, an RFID reader located at an entrance or exit of a venue or vehicle; and a computer assigned to a venue or vehicle. The RFID reader detects the RFID tag and the computer generates and transmits a first message containing information regarding a date and time when the RFID tag was detected and location information regarding the venue or vehicle. The personal monitoring device processes information regarding the address or location of the venue or vehicle using information regarding a travel itinerary or schedule of the individual. The personal monitoring device determines that the individual is not following, or has deviated from, the travel itinerary or schedule and generates and transmits a second message to a user communication device or central processing computer.

Calibrating a pressure sensor of a mobile device incudes determining an absolute calibration value used to calibrate pressure measurements by a pressure sensor of a mobile device; determining a first revisit zone as a first location to which the mobile device repeatedly returns; determining first and second calibrations for first and second visits to the first revisit zone; determining a first relative calibration adjustment value based on a difference between the first and second calibrations; determining an adjusted absolute calibration value based on a sum of the absolute calibration value and the first relative calibration adjustment value; and estimating an altitude of the mobile device based on a pressure measurement by the pressure sensor and the adjusted absolute calibration value.

A processor enabled method in a mobile device includes configuring a WiFi radio controller of the mobile device with a WiFi service set identifier of a search detector and configuring a Bluetooth connection configuration of a search detector. The method also includes responsive to a rescue trigger, enabling the device to exit a low power mode while awaiting a connection attempt from a Bluetooth radio via the configured Bluetooth connection configuration. The method also includes upon receiving the connection attempt, powering up the WiFi radio and attempting to connect to the configured WiFi service set identifier.

This invention relates to system and a method for supervising a person in an area, the system comprising a mobile base (100), such as for example a wristband,attached to the person, the mobile base (100) comprising a first radio frequency tag (11) prepared for radio frequency triangulation or positioning for deciding a position of the mobile base (100) and for communicating health, safety and environment (HSE) related components, the system comprising a controller (400) in communication with the mobile base (100). Furthermore, the invention relates to a system and a method for activated communication between an object and a reader,comprising a first radio unit (11) attached to the object, the first radio unit being configured for communicating with the reader.

In accordance with at least one aspect of this disclosure, a real time location services (RTLS) system, comprises one or more location anchor beacons configured to output a location anchor signal indicative of a location of the location anchor beacon in a physical space. One or more readers are configured to receive an asset tag signal from one or more asset tag beacons which are configured to receive the location anchor signal from the one or more location anchors. A location module is configured to receive the asset tag signal and to determine a physical location of the one or more asset tag beacons based on information indicative of a proximity to one or more of the one or more location anchor beacons included in the asset tag signal.

In one embodiment, an apparatus (12) is presented that detects wireless signals from external devices (18) that uniquely identify each of the external devices, records, in memory (30), information about the external devices without access to an external database, and compares information from the external devices to determine a relative location of the wearable device without using additional, power-hungry position location functionality if there is a threshold match in the compared information. In some embodiments, the invention uses the determined relative location to trigger an action at another device. The invention, using self-contained functionality, enables improvements in same location or home location determination accuracy, memory conservation, and power consumption.

A method includes, by a mobile device, receiving a Global Navigation Satellite System (GNSS) signal, and receiving, from a wireless device, via a PC5 interface, a message including a location of a reference structure. The method also includes determine whether the GNSS signal is a spoofing signal based on a difference between the location of the reference structure and a location of the mobile device determined based on the GNSS signal.
