SIGNATURES NITHIN PV LOHITH A GIRISH KUMAR DN VENKATESH MN ABSTRACT The world today is moving ahead at a very fast pace. Some of the very common examples of fast moving objects are aeroplanes, high speed cars and many more. In our everyday life we come across many fast moving vehicles and so it is very important to measure the speed of these vehicles. This is an era of automation where it is broadly defined as replacement of manual effort by mechanical power in all degrees of automation. The operation remains an essential part of the system although with changing demands on physical input as the degree of mechanization is increased. Rain operated motor is consists of conduction sensor (Tough sensor) circuit, Control Unit, wiper motor and glass frame. The sensor is used to detect the rain or water flow. There is any rain on the class, the sensor senses the rain or flow water and giving the control signal to the wiper motor. I CONTENTS 1.

Anderson's 1903 window cleaner design American inventor Mary Anderson is popularly credited with devising the first operational windshield wiper in 1903. In Anderson's patent, she called her invention a "window cleaning device" for electric cars and other vehicles. Operated via a lever from inside a vehicle, her version of windshield wipers closely resembles the windshield wiper found on many early car models. Anderson had a model of her design manufactured, then filed a patent (US 743,801) on June 18, 1903 that was issued to her by the US Patent Office on November 10, 1903. Douglass's 1903 locomotive cab window cleaner A similar device is recorded 3 months prior to Anderson's patent, with Robert A Douglass filing a patent for a "locomotive-cab-window cleaner" on 12 March 1903.[5] Apjohn's 1903 window cleaning apparatus design Irish born inventor James Henry Apjohn (1845–1914) patented an "Apparatus for Cleaning Carriage, Motor Car and other Windows" which was stated to use either brushes or wipers and could be either motor driven or hand driven. The brushes or wipers were intended to clean either both up and down or in just one direction on a vertical window. Apjohn's invention had a priority date in the UK of 9 October 1903.[6] In April 1911, a patent for windscreen wipers was registered by Sloan & Lloyd Barnes, patent agents of Liverpool, England, for Gladstone Adams of Whitley Bay. The first designs for the windscreen wiper are also credited to Polish concert pianist Józef Hofmann, and Mills Munitions, Birmingham who also claimed to have been the first to patent 1 NHCE-MECHANICAL DEPARTMENT AUTOMATIC RAIN SENSING WIPER 2015-16 windscreen wipers in England. John R. Oishei (1886-1968) formed the Tri-Continental Corporation in 1917. This company introduced the first windshield wiper, Rain Rubber, for the slotted, two-piece windshields found on many of the automobiles of the time. Today Trico Products is one of the world's leading manufacturers of windshield wiping systems, windshield wiper blades and refills, with wiper plants on five continents.[citation needed] Bosch has the world's biggest windscreen wiper factory in Tienen, Belgium, which produces 350,000 wiper blades every day. Inventor William M. Folberth applied for a patent for an automatic windscreen wiper apparatus in 1919, which was granted in 1922. It was the first automatic mechanism.[clarification needed] Trico

  • The Complex Patent Ecosystem and Its Implications for the Patent System
    Chien_62-HLJ-297 (Do Not Delete) 2/4/2011 2:27 PM From Arms Race to Marketplace: The Complex Patent Ecosystem and Its Implications for the Patent System Colleen V. Chien* For years, high-tech companies have amassed patents in order to deter patent litigation. Recently, a secondary market for patents has flourished, making it more likely that patents that would otherwise sit on the shelf will end up in the courtroom. This Article explores the current patent ecosystem, which includes both “arms race” and “marketplace” paradigms, in depth. I distinguish “patent-assertion entities,” entities that use patents primarily to obtain license fees rather than to support the development or transfer of technology, from other types of non-practicing entities. I contrast the patent arms race, whose goal is to provide entities with the freedom to operate, with the marketplace, through which entities have leveraged their freedom to litigate. I detail the participation of product companies as well as non-practicing companies and their intermediaries in the marketplace, and trace the diverse “pathways” traveled by patents from a diversity of sources including failed startups and product companies like Micron, to entities like Round Rock and Intellectual Ventures. Several implications follow. First, the failure of the patent arms race to deter lawsuits from patent assertion entities as well as practicing companies in certain cases means that defensive strategies must be reconceptualized to include new tactics—including prevention, disruption, and coordination—for securing freedom to operate. In addition, if stockpiles of unused patents patent continue to fall into the hands of patent-assertion entities, defensive patenting may ironically have the net effect of increasing, rather than decreasing, litigation risk.

  • Flash of Genius 2008
    Flash of Genius 2008 Flash of Genius is a 2008 American biographical film directed by Marc Abraham. The screenplay by Philip Railsback, based on a 1993 New Yorker article by John Seabrook,[2] focuses on Robert Kearns and his legal battle against the Ford Motor Company when they developed an intermittent windshield wiper based on ideas the inventor had patented. The film's title, the phrase "flash of genius," is patent law terminology which was in effect from 1941 to 1952, which held that the inventive act must come into the mind of an inventor as a kind of epiphany and not as a result of tinkering. Although this test lasted little more than a decade, it was most likely an appealing and easy standard for judges and unsophisticated jurors to apply to any given patent dispute when the technology being disputed was beyond their scientific acumen.
