Title: System and method for efficiently charging a battery over a linear or nonlinear interface
Inventor: FITZGERALD JOSEPH R
IPC: H02J7/10
Filed: 2000-12-28
Granted: 2008-01-08
Abstract: The system includes a first mechanism for receiving a feedback signal and providing a charging signal to the battery over a first electrical path when the feedback signal indicates that the battery is not fully charged. A second mechanism measures a voltage state of the battery via second and third electrical paths and provides the voltage state as the feedback signal to the first mechanism in response thereto. In the specific embodiment, the first mechani sm is a controllable power supply and the second mechanism is a sensing circuit. The sensing circuit includes a subtractor circuit that subtracts the voltage on the second electrical path from the voltage on the third electrical path and provides the feedback signal in response thereto. The second electrical path includes a wire connected between a first terminal of the subtractor circuit and a positive terminal of the battery.

Abstract: A method of clearing blockages below a reciprocating downhole tubing pump and a reciprocating downhole tubing pump. A standing ball valve assembly is axially movable along a barrel with axial travel being limited by an underlying axial stop. A spring is positioned between the standing ball valve and the axial stop. The spring biases the standing ball valve assembly into an operative position. Upon a travelling ball valve engaging the standing ball valve assembly and a compressive force being exerted upon the spring, the standing ball valve assembly is moved to a circulating position in which a first pin prevents a ball from engaging a ball seat on the travelling ball valve and a second pin prevents a ball from engaging a ball seat on the standing ball valve assembly. This permits a circulation of fluids through both the travelling ball valve and the standing ball valve assembly.

Title: Surgical stapling instrument incorporating an articulation joint for a firing bar track
Inventor: HOFFMAN DOUGLAS B
IPC: A61B17/32
Filed: 2004-07-09
Granted: 2012-04-24
Abstract: A surgical stapling and severing instrument particularly suited to endoscopic articulates an end effector by having a geared articulation mechanism that converts rotational motion from a handle portion. A firing bar longitudinally translates between the handle portion and the end effector. The firing bar head is thickened in order to present an undistorted cutting edge and engagement features to the opposing jaws of the end effector. The firing bar also advantageously includes a thinned or tapered proximal portion in the form of a strip or band that negotiates the articulation mechanism flexibility. To prevent buckling of the firing bar strip during firing, a pair of support plates adjustably flank the firing bar strip through the articulation mechanism. To advantageously prevent pinching, retaining bars are positioned between the support plates above the firing bar to maintain spacing therethrough.
