摘要： 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.

摘要： Systems and methods for navigating an aerial vehicle are provided. One example aspect of the present disclosure is directed to a method for navigating an aircraft. The method includes receiving, by one or more processors, one or more first geographic coordinates via an interface configured to receive geographic coordinates from a satellite transmission. The method includes receiving, by the one or more processors, one or more second geographic coordinates via an interface configured to receive geographic coordinates from a ground transmission. The method includes determining, by the one or more processors, that the one or more first geographic coordinates and the one or more second geographic coordinates are inconsistent. The method includes updating, by the one or more processors, a flight plan using the one or more second geographic coordinates when the one or more first geographic coordinates are inconsistent with the one or more second geographic coordinates.

摘要： A beacon transmitter including a wireless transceiver and an electronic controller coupled to the wireless transceiver. The electronic controller is configured to repeatedly transmit, via the wireless transceiver, a first beacon signal through a first number of transmission repetitions spaced at a first repeat interval, and receive an acknowledgement signal via the wireless transceiver. The electronic controller is also configured to stop transmission of the first beacon signal for a first predetermined amount of time based on receipt of the acknowledgement signal, determine that the first predetermined amount of time has expired, and resume repeatedly transmitting, via the wireless transceiver, the first beacon signal in response to determining that the predetermined amount of time has expired.

摘要： A magnetic beacon and inertial sensor system for precise indoor localization is provided using active magnetic beacons, magnetometers and inertial measurement units. The system is designed to work in environments that are not conducive to radio frequency (RF) (such as GPS, cell, Wi-Fi, or Bluetooth) or optical techniques (CCTV, IR), such as inside heavy industrial plant settings, underground or underwater.

摘要： A localization system comprising a plurality of wireless reference nodes for detecting a location of a mobile device within an environment. Each node transmits localization beacon signals to be detected by the mobile device, and/or listens for localization beacon signals from the mobile device. Further, the system also provides or contributes to providing another utility into the environment (e.g. each node being a luminaire); and transmits and/or listens for control-related signals, other than localization beacon signals, related to controlling the provision of said utility, the control related signals being communicated on a same or overlapping frequency band as the localization beacon signals, one or more controllers are configured to control the transmission of and/or listening for the control-related signals to be time-multiplexed into different time slots than the transmission and/or listening for the localization beacon signals, between the time-slots of the control-related signals.

摘要： Systems and methods for transmitting beacon messages are described. A beacon message is transmitted from a first beacon device and broadcast to an area within a transmission range of the first beacon device. A mobile device receives and stores the message. When the mobile device is out of the range of the first beacon device and within the range of a second beacon device, the message is transmitted to the second beacon device and broadcast by the second beacon device.

摘要： The present invention provides an Anchor Master AM management method and a node. The method is used in a neighbor awareness network and includes: receiving, by a first node, a first synchronization beacon frame sent by a second node in the neighbor awareness network, wherein the first synchronization beacon frame comprises a first AMR, the first AMR comprises first MAC address information, Anchor Master information in the first node comprises a second AMR, and the second AMR comprises second MAC address information; updating, by the first node, the Anchor Master information according to the first Anchor Master information when the first AMR is lower than the second AMR, the first MAC address information is the same as the second MAC address information, and a Master Rank MR of the first node is higher than the first AMR, so as to resolve a problem that air interface resources are excessively consumed.

摘要： A wireless node for use in a network of wireless nodes, for performing a localization to determine a location of a mobile device based on respective beacon signals transmitted wirelessly between the mobile device and each of a plurality of the wireless nodes. The first wireless node is configured to: wirelessly transmit or receive the respective beacon signal for use in determining the location of the mobile device; and wirelessly transmit information vouching for one or more others of the wireless nodes as being trusted for use in the localization. This information is transmitted to a device performing the localization (e.g. the mobile device), for use in identifying one or more rogue versions of said wireless nodes.
