Abstract: Methods and systems for drilling subsea wells bores with dual-gradient mud systems include drilling the subsea well bore while employing a subsea pumping system, a subsea choke manifold and one or more mud return risers to implement the dual gradient mud system. When a well bore influx is detected, the well bore is shut in, and components determine if pressure control may be used to circulate the influx out of the well bore, the size of the influx, and how much the mud system weight will need to be reduced to match the dual gradient hydrostatic head before the influx reaches the subsea pump take point. The subsea pumping system, subsea choke manifold, and mud risers are isolated while the influx is circulated up one or more fluid passages in the drilling riser package using the surface pump, through the wellhead, and out the surface choke manifold.

Abstract: A method is provided for accurately sampling pixels in a fixed-format display, which is connected to a host computer through an analog video display adapter. The method comprises the step of confirming that the fixed-format display is able to receive a pixel clock signal from the analog video display adapter. Another step is sending the pixel clock signal across an analog video sync line so that synchronization data and the pixel clock signal will be contained on the analog video sync line. An additional step is receiving the pixel clock signal in the fixed-format display. A further step is applying the pixel clock signal in the fixed-format display to sample pixels.

Abstract: A monitor sends an alert to a host computer operatively coupled to the monitor. As a result of receiving the alert, the host computer retrieves display panel data and retrieves monitor control settings from the monitor. The host computer uses the display panel data and monitor control settings to compute a monitor display profile.

Abstract: A wireless network for supporting mobile unit traffic segmentation for a plurality of mobile units to associate each mobile unit with virtual networking services (VNS). The wireless network includes a plurality of radio units and access controllers. Each radio unit is adapted to initiate the connection of a mobile unit to the network by transmitting and receiving communication data to and from the mobile unit.

Abstract: A method and system are provided for protecting an analog video signal sent from a video signal source to a video display enabled to receive a protected video signal. The method includes sending a string of bit values in an encrypted format from the video display to the video signal source. The string of bit values is received in the video signal source and decrypted. The string of bit values is then divided into multi-bit segments in both the video display and the video signal source. A common multi-bit segment in the string of bit values is selected for both the video display and video signal source. A plurality of analog video channels is then sent in a switched order from the video signal source to the video display based on the common multi-bit segment. The plurality of analog video channels is finally decoded in the video display using the common multi-bit segment to decode the switched order.

The method includes the step of providing a horizontal sync line to carry a horizontal sync signal that occupies pre-defined time intervals as a representation of a horizontal sync pulse. Another step is signaling to the video display adapter that a reference amplitude pulse will be sent on a video data line. A further step is sending the reference amplitude pulse on a video data line during the pre-determined time intervals when the horizontal sync signal occupies the horizontal sync line.

A further step is transferring data between the host and video display on the horizontal sync line during time intervals that are not reserved for the horizontal sync signal.

Abstract: A bi-directional high speed video data transmission system. A transmitter transmits an encoded video data stream across a data pair to a receiver by switching a DC current, via a pair of transistors, across the two data lines comprising the data pair. As the current varies on the data lines, so too does the voltage. The receiver decodes the serial video data stream back into its component parts so that the video data may be displayed by an appropriate display device. A pair of summing resistors adds the AC currents seen across the data lines to reconstruct the original DC current as a DC return current. The DC return current may be used to drive a return transmitter located on the original receiving side in order to send video data to the original transmitting side of the bi-directional video data transmission system.

Abstract: Systems and methods of switching between internal and external display adapters in a portable computer system are described. In one aspect, a graphics controller is configured to convert video output signals that are received from a processing unit into locally-generated video control signals and to selectively transmit to a local video display the video control signals that are generated locally or video control signals that are received from a docking station interface. In this way, when undocked, a portable computer unit may drive the local video display with a local adapter that is optimized for mobile usage (e.g., enhanced power management) and, when docked, the portable computer unit may drive the local video display with a higher performance external display adapter, which typically is not constrained by power management considerations.
