  • Silicon Image Pushes New MHL 2.0 Chips For Phones And HDTVs With 1080P60 Video, Faster Charging

    engadget.com 4 days, 20 hours ago

    After taking a few years to get off of the ground, MHL (Mobile High-Definition Link) technology is now found in many modern phones as well as HDTVs from LG, Toshiba and Samsung. Now, Silicon Image has announced its second generation of chips to go in those devices with enhanced features. MHL if you'll recall, lets mobile devices connect to HDTVs via HDMI, while passing power and control signals along with the video. According to Silicon Image its new chips, the SiI8240 MHL transmitter (for phones, tablets,

  • Scientists Tweak Wireless Power Transfer, Tesla Nods Happily In His Grave

    engadget.com 2 weeks, 1 day ago

    Wireless charging may be all the rage these days, but actually beaming electricity -- as sketched above by the man Tesla himself -- still has some snags. North Carolina State U researchers have found a way to possibly vanquish the biggest problem: the difficulty of exactly matching resonant frequencies to amplify current. If external factors like temperature change the tuning of a transmitter even slightly then power drops will occur, but circuitry developed by the NC State scientists would allow receivers

Additional Info

via Wikipedia
In electronics and telecommunications a transmitter or radio transmitter is an electronic device which, with the aid of an antenna, produces radio waves. The transmitter itself generates a radio frequency alternating current, which is applied to the antenna. When excited by this alternating current, the antenna radiates radio waves. In addition to their use in broadcasting, transmitters are necessary component parts of many electronic devices that communicate by radio, such as cell phones, wireless computer networks, Bluetooth enabled devices, garage door openers, two-way radios in aircraft, ships, and spacecraft, radar sets, and navigational beacons. The term transmitter is usually limited to equipment that generates radio waves for communication purposes; or radiolocation, such as radar and navigational transmitters. Generators of radio waves for heating or industrial purposes, such as microwave ovens or diathermy equipment, are not usually called transmitters even though they often have similar circuits.
