摘要： A handheld computing device comprises a thin enclosure having two opposing major faces. A display screen is disposed on a first one of the major opposing faces of the enclosure and a touch-sensitive object position detector input device is disposed on a second one of the major opposing faces of the enclosure. Computing device circuitry, circuitry for interfacing the touch-sensitive object position detector to the computing device circuitry, and circuitry for driving the display screen are all disposed within the enclosure.

摘要： A proximity sensor system includes a sensor matrix array having a characteristic capacitance on horizontal and vertical conductors connected to sensor pads. The capacitance changes as a function of the proximity of an object or objects to the sensor matrix. The change in capacitance of each node in both the X and Y directions of the matrix due to the approach of an object is converted to a set of voltages in the X and Y directions. These voltages are processed by analog circuitry to develop electrical signals representative of the centroid of the profile of the object, i.e., its position in the X and Y dimensions. The profile of position may also be integrated to provide Z-axis (pressure) information.

摘要： A valve including a housing having an inlet and an outlet, a piston disposed in the housing, the piston having a first end and a second end, the piston movable between a position blocking fluid flow between the inlet and the outlet and a position allowing fluid flow between the inlet and the outlet, a pressure balance pathway through the housing porting the same pressure to both first and second ends of the piston, an actuator responsive to applied pressure on the valve, the actuator attached to the piston and a biasing arrangement configured to bias the actuator toward a closed position of the valve. A method for injecting a sequestration fluid including maintaining the fluid at a supercritical phase upstream of a valve, opening the valve by increasing pressure of the fluid, delaying phase change of the fluid from supercritical to gas.

摘要： A flow control device is provided that in one embodiment includes a flow-through region configured to receive formation fluid at an inflow region and discharge the received fluid at an outflow region and a setting device configured to adjust the flow of the fluid through the flow-through region to a selected level. The setting device includes a coupling member configured to be coupled to an external latching device adapted to move the coupling member to cause the setting device to alter the flow of the fluid from the flow-through region to the selected level.
