  • Patent number: 8723551
    Abstract: Level shifting circuitry and corresponding enable signal generating circuitry provides improved leakage current control while eliminating the need for supplying reference voltage input in the enable signal generator. The level shifting circuitry is a type of cascode free level shifting circuit that does not include cascode transistors as in the prior art but instead utilizes cross coupled logic to provide level shifting while also utilizing enable signal controlled transistors to control leakage current through the cross coupled logic during power up sequencing. The level shifting circuitry provides improved leakage current limiting structure for power up sequencing whether a lower level supply voltage ramps up faster than the higher level supply voltage or vice a versa.

  • Publication number: 20140130079
    Abstract: A method and device for ranking video feeds provide a user with the best feed depending on what the user wishes to see. The method includes obtaining one or more video feeds and ranking the video feeds. The ranking is based, at least in part, upon input from a viewer indicating an object of interest. The ranking can consider things such as video stream resolution and signal strength.

  • Publication number: 20140126665
    Abstract: A system adjusts a voltage swing of an output driver based on a supply voltage. A supply voltage monitor generates a digital code indicating the difference between the supply voltage and nominal voltage representing a preferred level for the supply voltage. An impedance controller sets the voltage swing for the output driver based on the digital code, thereby keeping the voltage swing of the output driver output signal within specified limits while maintaining an impedance match with a load coupled to the output driver.

  • Publication number: 20140126612
    Abstract: A transmitting interconnect interface inserts clock mismatch compensation symbols into a transmitted data stream so as to allow the receiving interconnect interface to compensate for clock frequency mismatch between transmit-side and receive-side clocks. The transmitting interconnect interface adjusts the rate of insertion of these symbols based on a determination of the clock frequency mismatch. The transmitting interconnect interface can incrementally adjust the insertion rate to change substantially proportionally with changes in the clock frequency mismatch. Alternatively, the transmitting interconnect interface can set the insertion rate to one of two levels. By adapting the insertion rate to the current measured clock frequency mismatch, the bandwidth penalty incurred by transmitting clock mismatch compensation symbols in excess of that necessary to permit receiver clock tolerance compensation can be reduced, thereby permitting more transmit bandwidth to be used for transmitting data.

  • Publication number: 20140098296
    Abstract: A method and apparatus provides for changing a perspective of a video such as a display perspective of an object displayed in the video. In one example, the method and apparatus changes the display perspective of an object displayed in the video based on information indicating an orientation and/or position of the recording device that captures the object on the video. To do so, the method and apparatus may determine a current display perspective for an object displayed in the video based on information indicating an orientation and/or position of the recording device. By comparing the current display perspective to a desired display perspective for the object, the method and apparatus determines an amount of display perspective adjustment for the object and selects appropriate perspective adjustment methods to carry out the adjustment. Accordingly, the display perspective adjustment is made to the video automatically for the object displayed in the video without user intervention.

  • Publication number: 20140090792
    Abstract: A system and method for continuous casting. The system includes a melt chamber, a withdrawal chamber, and a secondary chamber therebetween. The melt chamber can maintain a melting pressure and the withdrawal chamber can attain atmospheric pressure. The secondary chamber can include regions that can be adjusted to different pressures. During continuous casting operations, the first region adjacent to the melt chamber can be adjusted to a pressure that is at least slightly greater than the melting pressure; the pressure in subsequent regions can be sequentially decreased and then sequentially increased. The pressure in the final region can be at least slightly greater than atmospheric pressure. The differential pressures can form a dynamic airlock between the melt chamber and the withdrawal chamber, which can prevent infiltration of the melt chamber by non-inert gas in the atmosphere, and thus can prevent contamination of reactive materials in the melt chamber.
