  • Publication number: 20150355920
    Abstract: Embodiments of the present disclosure may be configured to permit development and validation of a device driver or a device application program by using improved virtual devices. Such improved virtual devices may facilitate driver development without use of physical devices or hardware prototypes. In various embodiments, advanced validation of a device-driver combination may be permitted that would be difficult to achieve even with a physical device. Certain embodiments also may detect inconsistencies between virtual and physical devices, which may be used to improve drivers and device application programs and increase compatibility of such drivers and device application programs with physical devices.

  • Publication number: 20130234645
    Abstract: A portable solar energy generation system has a solar energy receiver having a plurality of solar cells for converting solar energy into a DC voltage. A solar tracking mechanism enables the solar energy receiver to track a position of the sun with respect to the solar cells and to position the solar cells responsive thereto. Power circuitry generates at least one output voltage to power an electronic device responsive to the DC voltage. A housing contains each of the solar energy receiver, the solar tracking mechanism and the power circuitry in a portable configuration.

  • Patent number: 7383733
    Abstract: A method and apparatus for detecting a high pressure condition within an interrupter includes introducing high intensity ultrasonic sound into the outer wall of a vacuum interrupter through a sonic wave guide, then listening for the reflected and retransmitted response signals. The characteristics of the response signals are utilized to determine the pressure within the interrupter, and to determine when an unwanted high pressure condition exists.
