  • Antenna for cellular handset with user adjustable gain
    Publication number: 20110169711
    Abstract: This invention addresses a flip antenna design for mobile devices operating in ISM 900 MHz band. More specifically the present invention addresses the need to change the gain of a transceiver antenna (for mobile devices) with the flip of the antenna without changing any other characteristics of the transceiver.

  • System and method for testing dynamic resistance during thermal shock cycling
    Publication number: 20060103404
    Abstract: A system includes a temperature chamber (100), a text fixture (402), a test coupon (400), a data acquisition unit (404), an ohmmeter (406) and a computer (410). The temperature chamber (100) provides temperature extremes to the test coupon (400). The test coupon (400) includes a substrate (314), one or more vias (418-429) and traces (402-412) connecting the vias. The data acquisition unit (404) continuously measures a resistance value of the circuit formed by the vias (418-429) and traces (402-412) during temperature cycling of the test coupon (400) held by the test fixture (402). The ohmmeter (406) measures the temperature of the test coupon (400) with a thermocouple. The data is used to detect failures of the materials in the test coupon (400) during the temperature cycling.
