Radar beacon (short: racon) is – according to article 1.103 of the International Telecommunication Union's (ITU) ITU Radio Regulations (RR) [1] – defined as "A transmitter-receiver associated with a fixed navigational mark which, when triggered by a radar, automatically returns a distinctive signal which can appear on the display of the triggering radar, providing range, bearing and ...
Bluetooth beacons use Bluetooth Low Energy proximity sensing to transmit a universally unique identifier [1] picked up by a compatible app or operating system. The identifier and several bytes sent with it can be used to determine the device's physical location, [2] track customers, or trigger a location-based action on the device such as a check-in on social media or a push notification .
Emergency locator beacon. An emergency locator beacon is a radio beacon, a portable battery powered radio transmitter, used to locate airplanes, vessels, and persons in distress and in need of immediate rescue. Various types of emergency locator beacons are carried by aircraft, ships, vehicles, hikers and cross-country skiers.
In order to use Bluetooth, a device must be compatible with the subset of Bluetooth profiles (often called services or functions) necessary to use the desired services. A Bluetooth profile is a specification regarding an aspect of Bluetooth-based wireless communication between devices. It resides on top of the Bluetooth Core Specification and (optionally) additional protocols. While the ...
iBeacon is based on Bluetooth low energy proximity sensing by transmitting a universally unique identifier [4] picked up by a compatible app or operating system. The identifier and several bytes sent with it can be used to determine the device's physical location, [5] track customers, or trigger a location-based action on the device such as a check-in on social media or a push notification .
The Bluetooth is split in two parts: a "controller stack" containing the timing critical radio interface, and a "host stack" dealing with high level data. The controller stack is generally implemented in a low cost silicon device containing the Bluetooth radio and a microprocessor. The host stack is generally implemented as part of an operating system, or as an installable package on top of an ...
Bluetooth Low Energy ( Bluetooth LE, colloquially BLE, formerly marketed as Bluetooth Smart [1]) is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group (Bluetooth SIG) [2] aimed at novel applications in the healthcare, fitness, beacons, [3] security, and home entertainment industries. [4] Compared to Classic Bluetooth, Bluetooth Low Energy ...
The Driver Monitoring System (DMS), also known as driver attention monitor, is a vehicle safety system to assess the driver's alertness and warn the driver if needed and eventually apply the brakes.
