  • Patent number: 7712944
    Abstract: An optical substrate possesses a structured surface that enhances luminance or brightness and reduces chatter phenomenon. A structured surface is provided, in which some of the valleys (low valleys) are coplanar to the surface of the underlying support layer and other valleys (high valleys) are not coplanar on the support layer. The low valleys have bottom thickness that is substantially smaller than that of the high valleys. The distance from the valleys to the support layer remains substantially similar for a first number of adjacent valleys, but is substantially zero for a second number of adjacent valleys after every n-th adjacent valleys.

  • Patent number: 7618164
    Abstract: An optical substrate having a structured surface that enhances brightness and reduces moiré effect. The optical substrate has a three-dimensionally varying, structured light output surface that comprises an irregular prismatic structure. The irregular prismatic structure may be viewed as comprising longitudinal prism blocks or rows thereof, arranged laterally defining peaks and valleys. Adjacent peaks, adjacent valleys, and/or adjacent peak and valley may be parallel or non-parallel, in an orderly, semi-orderly, random, or quasi-random manner. The lateral adjacent peaks, adjacent valleys, and/or adjacent peak and valley are not parallel. The adjacent irregular prism blocks may be irregular longitudinal sections having the same length, or random or quasi-random irregular sections having different lengths. The facets of each prism block may be flat, or curved (convexly and/or concavely).

  • Publication number: 20090261937
    Abstract: An integrated inductor includes a winding consisting of an aluminum layer atop a passivation layer, wherein the aluminum layer does not extend into the passivation layer and has a thickness that is not less than about 2.0 micrometers. The passivation layer has a thickness not less than about 0.8 micrometers. By eliminating copper from the integrated inductor and increasing the thickness of the passivation layer, the distance between the bottom surface of the inductor structure and the main surface of the semiconductor substrate is increased, thus the parasitic substrate coupling may be reduced and the Q-factor may be improved. Besides, the increased thickness of the aluminum layer may help improve the Q-factor as well.

  • Publication number: 20090207036
    Abstract: The present invention provides an automatic detecting device for radio frequency environment used to detect radio frequency noise. The device uses an antenna to receive radio frequency noise and the radio frequency noise is passing a radio frequency comparator and transformed into a voltage signal. Then, the voltage signal passes through an amplifier and is amplified to be an output voltage. If the output voltage exceeds a threshold voltage, it drives a post stage circuit to warn when the radio frequency noise is beyond a normal value.

  • Publication number: 20090184719
    Abstract: A device and method for investigating the IC (integrated circuit) testing environment is disclosed herein. The investigative device comprises a loadboard, a socket and an antenna. The loadboard is disposed in the bottom of the investigative device. The socket is disposed over the loadboard. The socket is used to fasten the element under test (such as IC) and the element under test is electrically connected to the loadboard. The antenna is also disposed in a position over the loadboard and closed to the socket. The purpose to dispose the antenna is to receive the wireless signal and monitor the testing environment if there is too much noise around the testing environment to jam the IC testing.
