Vijay Nahar has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Methods for testing manufactured products
    Patent number: 9081051
    Abstract: The problem of high test cost of manufactured goods can be partially solved by lowering the percentage of the goods to be tested methodically while keeping the total defective portion of the goods expressed in DPPM below a preset target value. The method includes identifying a first test that is capable of screening out enough parts that would fail a second test so that the portion of the parts to be tested second test can be reduced. The number of parts screened out by the first test determines if the reduced testing scheme would violate the preset DPPM target value.
    Type: Grant
    Filed: October 10, 2011
    Date of Patent: July 14, 2015
    Assignee: TEXAS INSTRUMENTS INCORPORATED
    Inventors: Amit Vijay Nahar, Ben Chia-Ming Chang, Nelson Kei Leung, Francis Eongsoo Lim

  • Dual band diversity wlan antenna system for laptop computers, printers and similar devices
    Patent number: 7342540
    Abstract: There is disclosed a dual band antenna device including a dielectric substrate (6) having opposed first and second surfaces and a groundplane (7) on the second surface. A microstrip transmission line (4) is provided on the first surface, and a dielectric pellet (5) is mounted on the first surface on the microstrip transmission line (4). A bifurcated planar inverted-L antenna (PILA) component (1) is also mounted on the first surface, the PILA component (1) having first (2) and second (3) arms which extend over and contact a surface of the dielectric pellet (5). The first arm (3) contacts a different area of the surface of the dielectric pellet (5) than the second arm (2). The antenna device provides good operation at both 2.4 GHz and 5.5 GHz frequency bands.
