A system and a method for operating a lighting device may include a transmission device and an optional communication unit. The transmission device may be configured to wirelessly transmit a radio signal with identification data specific to the transmission device of the lighting device via at least two radio channels. The transmitted radio signal transmitted via a respective one of the at least two channels may include channel data with respect to the respective one of the radio channels. In a non-limiting embodiment, the transmission device is a beacon.

Presently disclosed is a system, apparatus, and method for navigating and orienting roadway vehicles by use of a network of embedded navigation beacons within a roadway. A plurality of primary navigation beacons are embedded into a roadway surface with sensors, and communicate with a car and a smaller subset of secondary beacons with connection to the internet. Further disclosed is a landing pad for a drone delivery system, the landing pad acting as a navigational beacon and safe landing location indicator for the aerial drone.

A microwave-based radio system for realising a precise landing approach (MLS), characterised in that an azimuth antenna transmitter and/or an elevation signal transmitter and/or a DME transmitter, and preferably all three said transmitters, are placed aboard an unmanned aerial vehicle, and in particular on a drone. The object of the disclosure is also a method for realising a precise landing approach using such a system.

A location system, comprises multiple nodes, each of which receiving and transmitting signals from and to user equipment. The system further comprises a processor configured to determine a location of the user equipment in a space having at least one node. The system is configured to interprets the location of the user equipment based on power of at least one signal transmitted to at least one of the nodes, a received signal strength of the user equipment at one of the nodes, and distances between the user device and at least two nodes.

A detector base for fixing to a mounting surface may include a connection for connecting to a detector line of a hazard alarm system and a first connection side for releasably attaching a hazard detector embodied as a point detector. The first connection side may be electrically and structurally co-ordinated with a second connection side of such a hazard detector, such that the latter is releasably attachable to the detector base and is indirectly connectable via the latter to the detector line. The detector base may include a radio device affixed to the detector base and serving for transmitting position data of the detector base mounting location and/or for transmitting a reference to a database having said position data. The radio device may be based on a Bluetooth low energy standard.

A system for locating a debris field resulting from a plane crash comprises a plurality of low-power, battery operated electronic transponder tags, and at least one locator operative to the interrogate the tags to determine the location thereof. The tags are placed on or in an airplane in multiple locations, thereby enabling the locator to determine the location of a debris field in the event of a crash. The locator, which may be airborne, preferably reports tag positions for map display. The tags may be hermetically sealed to prevent water infiltration, and may be triggered to an active state in response to a large acceleration or always in an ON state. Tags placed on or in the airplane may be mounted in a manner to intentionally detach. The tags may further include a barometric pressure sensor, a shock sensor and/or an accurate time base to record the time of a crash.

A method of generating an elevator call using a mobile device including: detecting a first advertisement emitted by a first beacon, the first beacon being located at a first location and the first beacon is configured to emit the first advertisement a first selected range away from the first beacon; determining that an individual will be boarding an elevator system based on at least the first location of the first beacon; and transmitting the elevator call to a dispatcher of the elevator system based on determining that the individual will be boarding the elevator system or authorizing a previously placed elevator call to the dispatcher based on determining that the individual will be boarding the elevator system.

An identity-locked personal item is provided with a lock body configured to receive and release an engagement member upon receiving a matched biometric imprint from an authorized user. An actuator mechanism is connected to at least one capacitive surface and a controller with an integrated power supply inside the lock body, the lock body being further integrated into a secured container. The controller is configured to receive a contact datum from the capacitive surface, the actuator mechanism being operated upon recognition of a known datum or biometric signature.

Beacon systems include a beacon including a transmitter, a processor, and a sensor for collecting sensor data, wherein the beacon broadcasts a beacon message comprising informational data based on a value of the sensor data and data regarding a minimum received signal strength for the relevance of the beacon message. The beacon system may include a receiving device, wherein the receiving device comprises a processor and an alarm adapted to be triggered by the beacon message, wherein the processor determines a relevance of the beacon message by comparing the minimum received signal strength for the relevance of the beacon message to an actual received signal strength of the beacon message, wherein, if the actual received signal strength is greater than or equal to the minimum received signal strength, the receiving device is within a range of relevance and the alarm is triggered.

A luminaire-based positioning system including a plurality of luminaires, each respective luminaire including a luminaire identifier. The system includes a gateway including a luminaire node map of commissioned luminaires with a commissioned luminaire identifier and commissioned location coordinates of each commissioned luminaire. The gateway includes an undesignated luminaire roster of undesignated luminaires with a set of undesignated location coordinates. Further, the gateway includes a plurality of projected received signal strength indication (RSSI) values. Additionally, the gateway includes programming to determine an association of an uncommissioned luminaire to a safest fit undesignated luminaire of the undesignated luminaire roster. Further, programming to assign to the uncommissioned luminaire the set of undesignated location coordinates of the safest undesignated luminaire. Additionally, programming to adjust the luminaire node map by adding a new set of commissioned location coordinates with the uncommissioned luminaire identifier that most safely fit the determined set of uncommissioned location coordinates.
