Global Positioning System

GPSGlobal Positioning System (GPS)global positioning systems
Some GPS receivers may use additional clues or assumptions such as reusing the last known altitude, dead reckoning, inertial navigation, or including information from the vehicle computer, to give a (possibly degraded) position when fewer than four satellites are visible. The current GPS consists of three major segments. These are the space segment, a control segment, and a user segment. The U.S. Air Force develops, maintains, and operates the space and control segments. GPS satellites broadcast signals from space, and each GPS receiver uses these signals to calculate its three-dimensional location (latitude, longitude, and altitude) and the current time.


Bluetooth 2.1 + EDR4.0Bluetooth 2.1+EDR
Bluetooth exists in numerous products such as telephones, speakers, tablets, media players, robotics systems, laptops, and console gaming equipment as well as some high definition headsets, modems, hearing aids and even watches. Given the variety of devices which use the Bluetooth, coupled with the contemporary deprecation of headphone jacks by Apple, Google, and other companies, and the lack of regulation by the FCC, the technology is prone to interference. Nonetheless Bluetooth is useful when transferring information between two or more devices that are near each other in low-bandwidth situations.

Wearable technology

In early 2015, Pebble went back to its crowdfunding roots to raise a further $20m for its next-generation smartwatch, Pebble Time, which started shipping in May 2015. In March 2014, Motorola unveiled the Moto 360 smartwatch powered by Android Wear, a modified version of the mobile operating system Android designed specifically for smartwatches and other wearables. Finally, following more than a year of speculation, Apple announced its own smartwatch, the Apple Watch, in September 2014. Wearable technology was a popular topic at the trade show Consumer Electronics Show in 2014, with the event dubbed "The Wearables, Appliances, Cars and Bendable TVs Show" by industry commentators.

The company also became well known for the wide variety and innovation of its wristwatches. It was one of the earliest manufacturers of quartz watches, both digital and analog. It also began selling calculator watches during this time. It was one of the first manufacturers of watches that could display the time in many different time zones and of watches with temperature, atmospheric-pressure, altitude, and even Global Positioning System displays.

Although not specifically designed as one, some accessory makers produced watchbands for the 6th generation Nano, allowing it to be worn like a watch. In September 2013, TUAW compared the iPod Nano to the Samsung Galaxy Gear, and considered the three-year-old model to be a "better, cheaper smartwatch" than the Galaxy Gear because of its more complete functionality in comparison, and its inclusion of a headphone jack. Apple announced the seventh and final generation iPod Nano on September 12, 2012.

Timex Datalink

Timex Datalink or Timex Data Link is a line of early smartwatches manufactured by Timex and is considered a wristwatch computer. It is the first watch capable of downloading information from a computer. As the name implies, datalink watches are capable of data transfer through linking with a computer. The Datalink line was introduced in 1994 and it was co-developed with Microsoft as a wearable alternative to mainstream PDAs with additional attributes such as water resistance, that PDAs lacked, and easy programmability.

In the first six months of availability, Canalys estimates that over 720,000 Android Wear smartwatches were shipped., Wear OS had between 10 and 50 million application installations. Wear OS was estimated to account for 10% of the smart watch market in 2015. The platform was announced on March 18, 2014, along with the release of a developer preview. At the same time, companies such as Motorola, Samsung, LG, HTC and Asus were announced as partners. On June 25, 2014, at Google I/O, the Samsung Gear Live and LG G Watch were launched, along with further details about Android Wear. The LG G Watch is the first Android Wear smartwatch to be released and shipped.


Hattori SeikoHattori Seiko Co.lorus
After reconstructing and creating its operating subsidiaries (such as Seiko Watch Corporation and Seiko Clock Inc.), it became a holding company in 2001 and was renamed Seiko Holdings Corporation as of July 1, 2007. Seiko is perhaps best known for its wristwatches, all of which were at one time produced entirely in-house. This includes not only major items such as microgears, motors, hands, crystal oscillators, batteries, sensors, LCDs but also minor items such as the oils used in lubricating the watches and the luminous compounds used on the hands and the dials. Seiko watches were originally produced by two different subsidiaries. One was Diani Seikosha Co.

The Model 23 was a 16 size pocket watch case with a black dial; despite the pocket watch case, this was a stopwatch. The Model 4992b was in a 16 size case, with a black dial. It was used as the pocket watch for U.S. military, featuring a 21 jewel railroad grade movement. In 1951, Hamilton rebuffed a hostile takeover bid by the Benrus watch company. The fallout from the failed takeover action culminated in Hamilton Watch Co. vs Benrus Watch Co. (206 F.2d 738, 740 (2d Cir. 1953)), a Federal proceeding that is considered to be landmark case in the realm of Federal anti-trust case law.

Pulsar (watch)

Pulsar is a brand of watch and currently a division of Seiko Watch Corporation of America (SCA). Pulsar was the world's first electronic digital watch. Today Pulsar watches are mostly analog and use the same movements in Seikos such as the 7T62 quartz chronograph movement. In 1970, Pulsar was a brand of the American Hamilton Watch Company which first announced that it was making and bringing the LED watch to market. It was developed jointly by American companies Hamilton and Electro/Data Inc. In spring 1972, the first Pulsar watch was marketed by Hamilton Watch (the parent company, not the Hamilton Watch Division).

The company continued to focus on high-priced watch models and eventually fell into receivership, discontinuing business in July 1912. Robert H. Ingersoll & Bro. bought the Waterbury plant and began manufacturing Ingersoll Watches there in 1914. With the American entry into World War I there were new demands for timepiece design. Artillery gunners needed an easy way to calculate and read time while still being able to work the guns.


accelerometersG-sensoracceleration sensor
Within the last several years, several companies have produced and marketed sports watches for runners that include footpods, containing accelerometers to help determine the speed and distance for the runner wearing the unit. In Belgium, accelerometer-based step counters are promoted by the government to encourage people to walk a few thousand steps each day. Herman Digital Trainer uses accelerometers to measure strike force in physical training. It has been suggested to build football helmets with accelerometers in order to measure the impact of head collisions. Accelerometers have been used to calculate gait parameters, such as stance and swing phase.

Light-emitting diode

LEDLEDslight emitting diodes
The first commercial LEDs were commonly used as replacements for incandescent and neon indicator lamps, and in seven-segment displays, first in expensive equipment such as laboratory and electronics test equipment, then later in such appliances as calculators, TVs, radios, telephones, as well as watches (see list of signal uses). Until 1968, visible and infrared LEDs were extremely costly, in the order of US$200 per unit, and so had little practical use. The Monsanto Company was the first organization to mass-produce visible LEDs, using gallium arsenide phosphide (GaAsP) in 1968 to produce red LEDs suitable for indicators.

Elizabeth I of England

At her funeral on 28 April, the coffin was taken to Westminster Abbey on a hearse drawn by four horses hung with black velvet. In the words of the chronicler John Stow: Westminster was surcharged with multitudes of all sorts of people in their streets, houses, windows, leads and gutters, that came out to see the obsequy, and when they beheld her statue lying upon the coffin, there was such a general sighing, groaning and weeping as the like hath not been seen or known in the memory of man. Elizabeth was interred in Westminster Abbey, in a tomb shared with her half-sister, Mary I.
