On February 14, 2012, the FCC initiated proceedings to vacate LightSquared's Conditional Waiver Order based on the NTIA's conclusion that there was currently no practical way to mitigate potential GPS interference. GPS receiver manufacturers design GPS receivers to use spectrum beyond the GPS-allocated band. In some cases, GPS receivers are designed to use up to 400 MHz of spectrum in either direction of the L1 frequency of 1575.42 MHz, because mobile satellite services in those regions are broadcasting from space to ground, and at power levels commensurate with mobile satellite services.


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.

The second generation of Apple Watch, Apple Watch Series 2, was released in September 2016, featuring greater water resistance, a faster processor, and brighter display. On September 12, 2017, Apple introduced the Apple Watch Series 3 featuring LTE cellular connectivity, giving the wearable independence from an iPhone except for the setup process. On September 12, 2018, Apple introduced the Apple Watch Series 4, featuring new display, electrocardiogram and fall detection. At the 2007 Macworld conference, Jobs demonstrated the Apple TV (previously known as the iTV), a set-top video device intended to bridge the sale of content from iTunes with high-definition televisions.


Casio Computer Co., LtdCasio ComputerCASIO Computer Co.
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.

The draft was universal and included blacks on the same terms as whites, although they served in different units. In all 367,710 black Americans were drafted (13% of the total), compared to 2,442,586 white (87%). Forms of resistance ranged from peaceful protest to violent demonstrations and from humble letter-writing campaigns asking for mercy to radical newspapers demanding reform. The most common tactics were dodging and desertion, and many communities sheltered and defended their draft dodgers as political heroes. Many socialists were jailed for "obstructing the recruitment or enlistment service".

Because of the remarkable hardness of sapphires – 9 on the Mohs scale (the third hardest mineral, after diamond at 10 and moissanite at 9.5) – sapphires are also used in some non-ornamental applications, such as infrared optical components, high-durability windows, wristwatch crystals and movement bearings, and very thin electronic wafers, which are used as the insulating substrates of very special-purpose solid-state electronics (especially integrated circuits and GaN-based LEDs). Sapphire is the birthstone for September and the gem of the 45th anniversary. A sapphire jubilee occurs after 65 years.

Since this change, Timex has introduced GPS enabled watches, heart rate monitor exercise watches and similar high tech devices. In 2008, Timex Group USA signed a four-year agreement making Timex the first official timekeeper of the ING New York City Marathon. Meanwhile, parent company Timex Group B.V. launched two new Swiss-Made luxury watch brands – Salvatore Ferragamo Timepieces and Valentino Timeless – under the Timex Group Luxury Watches business. As the year closed, construction commenced on the second-largest ground mounted solar array in the northeastern United States at Timex Group USA's Middlebury, CT headquarters.

The Indian film industry produces the world's most-watched cinema. Established regional cinematic traditions exist in the Assamese, Bengali, Bhojpuri, Hindi, Kannada, Malayalam, Punjabi, Gujarati, Marathi, Odia, Tamil, and Telugu languages. South Indian cinema attracts more than 75% of national film revenue. Television broadcasting began in India in 1959 as a state-run medium of communication and had slow expansion for more than two decades. The state monopoly on television broadcast ended in the 1990s and, since then, satellite channels have increasingly shaped the popular culture of Indian society.

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.


On March 31, 1854, Commodore Matthew Perry and the "Black Ships" of the United States Navy forced the opening of Japan to the outside world with the Convention of Kanagawa. Subsequent similar treaties with Western countries in the Bakumatsu period brought economic and political crises. The resignation of the shōgun led to the Boshin War and the establishment of a centralized state nominally unified under the Emperor (the Meiji Restoration).

Elizabeth I of England

Elizabeth IQueen Elizabeth IQueen Elizabeth
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.

Garmin Forerunner

Garmin registered the name "Forerunner" with the United States Patent and Trademark Office in August 2001 but released the first watches — the 101, 201, and 301 — in 2003. In 2006, the improved 205 and 305 appeared. These models are smaller than the first generation and feature a more sensitive SiRFstarIII GPS receiver chip. In late 2007, the Forerunner 50 was introduced. As opposed to GPS, this model paired with a foot pod to measure displacement. The Forerunner 50 also came packaged with a USB stick that allowed training data to be transferred wirelessly to one's pc. This feature has since become a staple of Garmin's more full-featured sport watches.


Waterproofing is the process of making an object or structure waterproof or water-resistant so that it remains relatively unaffected by water or resisting the ingress of water under specified conditions. Such items may be used in wet environments or underwater to specified depths.

Outer space

This decrease in pressure was further demonstrated by carrying a half-full balloon up a mountain and watching it gradually expand, then contract upon descent. In 1650, German scientist Otto von Guericke constructed the first vacuum pump: a device that would further refute the principle of horror vacui. He correctly noted that the atmosphere of the Earth surrounds the planet like a shell, with the density gradually declining with altitude. He concluded that there must be a vacuum between the Earth and the Moon. Back in the 15th century, German theologian Nicolaus Cusanus speculated that the Universe lacked a center and a circumference.
