The Bluetooth protocol RFCOMM is a simple set of transport protocols, made on top of the L2CAP protocol, providing emulated RS-232 serial ports (up to sixty simultaneous connections to a Bluetooth device at a time). The protocol is based on the ETSI standard TS 07.10. RFCOMM is sometimes called serial port emulation.
Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to 10 metres (33 ft).
Fast Pair. The Google Fast Pair Service, or simply Fast Pair, is Google 's proprietary standard for quickly pairing Bluetooth devices when they come in close proximity for the first time using Bluetooth Low Energy (BLE). [1] It was announced in October 2017 and initially designed for connecting audio devices such as speakers, headphones and car ...
Noise -cancelling headphones alongside a carry case. Noise-cancelling headphones are headphones which suppress unwanted ambient sounds using active noise control. This is distinct from passive headphones which, if they reduce ambient sounds at all, use techniques such as soundproofing . Noise cancellation makes it possible to listen to audio ...

Four people were killed and several others injured in a shooting near a mosque in Oman 's capital, Muscat, in a rare flare of violence in the Middle Eastern Sultanate. The shooting took place near ...
The PAIR ( puncture-aspiration-injection-reaspiration; sometimes percutaneous aspiration-injection-reaspiration [1]) procedure is a noninvasive treatment option to remove hydatid cysts. [2] PAIR is considered an alternative treatment for cystic echinococcosis ( hydatid disease) and is often indicated for patients who do not respond to surgery ...
The axiom of pairing is generally considered uncontroversial, and it or an equivalent appears in just about any axiomatization of set theory. Nevertheless, in the standard formulation of the Zermelo–Fraenkel set theory, the axiom of pairing follows from the axiom schema of replacement applied to any given set with two or more elements, and thus it is sometimes omitted.
