Bluetooth Software
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 . It employs UHF radio waves in the ISM bands, from 2.402GHz to 2.48GHz. It is mainly used as an alternative to wired connections to exchange files between nearby portable devices and connect cell phones and music players with wireless headphones, wireless speakers, HIFI systems, car audio and wireless transmission between TVs and soundbars. Bluetooth is managed by the Bluetooth Special Interest Group (SIG), which has more than 35,000 member companies in the areas of telecommunication, computing, networking, and consumer electronics. The IEEE standardized Bluetooth as IEEE 802.15.1 but no longer maintains the standard. The Bluetooth SIG oversees the development of the specifi ...

Wireless Speakers
Wireless speakers are loudspeakers that receive audio signals using radio frequency (RF) waves rather than over audio cables. The two most popular RF frequencies that support audio transmission to wireless loudspeakers include a variation of WiFi IEEE 802.11, while others depend on Bluetooth to transmit audio data to the receiving speaker. Apart from the employed RF standard, such speakers can basically be distinguished by their dedicated field of use. Portable wireless speakers for outdoor use are typically designed for ruggedness, portability and battery life, whereas stationary wireless speakers with a focus on good sound quality are meant to be used in home audio systems or surround sound systems for TV or video. Further, types for special applications like waterproof speakers for use in the shower or speakers for a Voice user interface, voice assistant may intermix between the properties of the two former.

Jelling Stones
The Jelling stones () are massive carved runestones from the 10th century, found at the town of Jelling in Denmark. The older of the two Jelling stones was raised by King Gorm the Old in memory of his wife Thyra. The larger of the two stones was raised by King Gorm's son, Harald Bluetooth, in memory of his parents, celebrating his conquest of Denmark and Norway, and his conversion of the Danes to Christianity. The runic inscriptions on these stones are considered the best known in Denmark. In 1994, the stones, in addition to the burial mounds and small church nearby, were inscribed on the UNESCO World Heritage List as an unparalleled example of both pagan and Christian Nordic culture. Significance The stones are strongly identified with the creation of Denmark as a nation state. Both inscriptions mention the name "Danmark" (in the form of accusative "tanmaurk" () on the large stone, and genitive "tanmarkar" (pronounced ) on the small stone). The larger stone explicitl ...

Harald Bluetooth
Harald "Bluetooth" Gormsson (; , died c. 985/86) was a king of Denmark and Norway. The son of King Gorm the Old and Thyra Dannebod, Harald ruled as king of Denmark from c. 958 – c. 986, introduced Christianization of Denmark, Christianity to Denmark and consolidated his rule over most of Jutland and Zealand. Harald's rule as king of Norway following the assassination of King Harald II of Norway, Harald Greycloak of Norway was more tenuous, most likely lasting for no more than a few years in the 970s. Some sources say his son Sweyn Forkbeard forcibly deposed him from his Danish throne before his death. Name Harald's name is written as runic ''haraltr : kunukʀ'' (ᚼᛅᚱᛅᛚᛏᚱ ᛬ ᚴᚢᚾᚢᚴᛦ) in the Jelling stone inscription. In normalized Old Norse, this would correspond to ''Haraldr konungr'', i.e. "Harald Germanic king, king". The Latinized name as given in the medieval Danish chronicles is ''Haraldus Gormonis filius'' (Harald, Gorm's son). The given name ...

The Long Ships
''The Long Ships'' or ''Red Orm'' (original Swedish: ''Röde Orm'' meaning ''Red Orm'', lit. ''Red Serpent'' or ''Red Snake'') is an adventure novel by the Swedish writer Frans G. Bengtsson. The narrative is set in the late 10th century and follows the adventures of the Viking Röde Orm - called "Red" for his hair and his temper, a native of Scania. The book portrays the political situation of Europe in the later Viking Age, Andalusia under Almansur, Denmark under Harald Bluetooth, followed by the struggle between Eric the Victorious and Sven Forkbeard, Ireland under Brian Boru, England under Ethelred the Unready, and the Battle of Maldon, and then the Byzantine Empire and its Varangian Guard, Kievan Rus and its neighbors the Patzinaks - all before the backdrop of the gradual Christianization of Scandinavia, contrasting the pragmatic Norse pagan outlook with the exclusiveness of Islam and Christianity. The novel is divided into two parts, published in 1941 and 1945, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Internet Of Things
Internet of things (IoT) describes devices with sensors, processing ability, software and other technologies that connect and exchange data with other devices and systems over the Internet or other communication networks. The IoT encompasses Electronic engineering, electronics, Telecommunications engineering, communication, and computer science engineering. "Internet of things" has been considered a misnomer because devices do not need to be connected to the public internet; they only need to be connected to a network and be individually addressable. The field has evolved due to the convergence of multiple technologies, including ubiquitous computing, commodity sensors, and increasingly powerful embedded systems, as well as machine learning.Hu, J.; Niu, H.; Carrasco, J.; Lennox, B.; Arvin, F.,Fault-tolerant cooperative navigation of networked UAV swarms for forest fire monitoring Aerospace Science and Technology, 2022. .

Integrated Circuit
An integrated circuit (IC), also known as a microchip or simply chip, is a set of electronic circuits, consisting of various electronic components (such as transistors, resistors, and capacitors) and their interconnections. These components are etched onto a small, flat piece ("chip") of semiconductor material, usually silicon. Integrated circuits are used in a wide range of electronic devices, including computers, smartphones, and televisions, to perform various functions such as processing and storing information. They have greatly impacted the field of electronics by enabling device miniaturization and enhanced functionality. Integrated circuits are orders of magnitude smaller, faster, and less expensive than those constructed of discrete components, allowing a large transistor count. The IC's mass production capability, reliability, and building-block approach to integrated circuit design have ensured the rapid adoption of standardized ICs in place of designs using discre ...

Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an sufficiency of disclosure, enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private la ...
