Magnetic Positioning
Magnetic positioning is an IPS (Indoor positioning system) solution that takes advantage of the magnetic field anomalies typical of indoor settings by using them as distinctive place recognition signatures. The first citation of positioning based on magnetic anomaly can be traced back to military applications in 1970. The use of magnetic field anomalies for indoor positioning was instead first claimed in papers related to robotics in the early 2000. Most recent applications can employ magnetic sensor data from a smartphone used to wirelessly locate objects or people inside a building. There is currently no de facto standard for IPS, however magnetic positioning appears to be the most complete and cost effective. It offers accuracy without any hardware requirements and a relatively low total cost of ownership. According to Opus Research magnetic positioning will emerge as a “foundational” indoor location technology. Companies GiPStech Independent research brought in 2011 a ...

Indoor Positioning System
An indoor positioning system (IPS) is a network of devices used to locate people or objects where GPS and other satellite technologies lack precision or fail entirely, such as inside multistory buildings, airports, alleys, parking garages, and underground locations. A large variety of techniques and devices are used to provide indoor positioning ranging from reconfigured devices already deployed such as smartphones, WiFi and Bluetooth antennas, digital cameras, and clocks; to purpose built installations with relays and beacons strategically placed throughout a defined space. Lights, radio waves, magnetic fields, acoustic signals, and behavioral analytics are all used in IPS networks. IPS can achieve position accuracy of 2 cm, which is on par with RTK enabled GNSS receivers that can achieve 2 cm accuracy outdoors. IPS use different technologies, including distance measurement to nearby anchor nodes (nodes with known fixed positions, e.g. WiFi / LiFi access points, Bluet ...

Smartphone
A smartphone is a portable computer device that combines mobile telephone and computing functions into one unit. They are distinguished from feature phones by their stronger hardware capabilities and extensive mobile operating systems, which facilitate wider software, internet (including web browsing over mobile broadband), and multimedia functionality (including music, video, cameras, and gaming), alongside core phone functions such as voice calls and text messaging. Smartphones typically contain a number of metal–oxide–semiconductor (MOS) integrated circuit (IC) chips, include various sensors that can be leveraged by pre-included and third-party software (such as a magnetometer, proximity sensors, barometer, gyroscope, accelerometer and more), and support wireless communications protocols (such as Bluetooth, Wi-Fi, or satellite navigation). Early smartphones were marketed primarily towards the enterprise market, attempting to bridge the functionality of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Università Della Calabria
The University of Calabria ( it, Università della Calabria, UNICAL) is a state-run university in Italy. Located in Arcavacata, a hamlet of Rende and a suburb of Cosenza, the university was founded in 1972. Among its founders there were Beniamino Andreatta, Giorgio Gagliani, Pietro Bucci and Paolo Sylos Labini. It currently has about 35,000 students, 800 teaching and research staff and about 700 administrative staff. Campus The Campus of the University of Calabria was originally designed by Vittorio Gregotti and Dänen Martensson. The buildings are situated along a suspension bridge, which is currently 1.3 kilometres long. As in British and North-American campuses, students live in specific residential blocks near the University. The whole structure is swathed in greenery of hills near Arcavacata, a small village at 10 km from Cosenza, and 4 km from the city center of Rende.

Oulu
Oulu ( , ; sv, Uleåborg ) is a city, municipality and a seaside resort of about 210,000 inhabitants in the region of North Ostrobothnia, Finland. It is the most populous city in northern Finland and the fifth most populous in the country after: Helsinki, Espoo, Tampere and Vantaa, and the fourth largest urban area in the country after Helsinki, Tampere and Turku. Oulu's neighbouring municipalities are: Hailuoto, Ii, Kempele, Liminka, Lumijoki, Muhos, Pudasjärvi, Tyrnävä and Utajärvi. Due to its large population and geopolitically economic and cultural-historical location, Oulu has been called the "capital of Northern Finland". Oulu is also considered one of Europe's "living labs", where residents experiment with new technology (such as NFC tags and ubi-screens) on a community-wide scale. Despite only ranking in the top 2% universities, the University of Oulu is regionally known in the field of information technology. Oulu has also been very successful in recent urban ima ...

Wired UK
''Wired UK'' is a bimonthly magazine that reports on the effects of science and technology. It covers a broad range of topics including design, architecture, culture, the economy, politics and philosophy. Owned by Condé Nast Publications, it is published in London and is an offshoot of the original American ''Wired''. History Earlier version (mid–1990s) The magazine's current incarnation follows an earlier attempt at a British edition of ''Wired'' which ran from April 1995 until March 1997. It was initially created as a joint venture with the Guardian Media Group and ''Wired US''s then owners, Wired Ventures, but that incarnation lasted only three or four issues, due to a culture clash between the two parties and low sales figures of 25,000 per month. Wired Ventures then ran the UK edition alone, with an almost entirely new staff, until the magazine was closed with the March 1997 issue, when sales were at 40,000 magazines per month. Current version (2009–present) The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
