  • Systems, methods, and apparatus to drive reactive loads
    Patent number: 9641072
    Abstract: Systems, methods, and apparatus to drive reactive loads are disclosed. An example apparatus to drive a reactive load includes a reactive component in circuit with the reactive load, a first switching element in circuit with the reactive load to selectively hold the reactive load in a first energy state and to selectively allow the reactive load to change from the first energy state to a second energy state, a second switching element in circuit with the reactive load to selectively hold the reactive load in the second energy state and to selectively allow the reactive load to change from the second energy state to the first energy state, and a controller to detect a current in the reactive load, and to control the first and second switching elements to hold the reactive load in the first or the second energy state when the current traverses a threshold.

  • Borehole Tool
    Publication number: 20160123130
    Abstract: A borehole tool used in a borehole comprises a tool body, a plurality of arms connected to the tool body so as to be movable radially relative thereto between a closed position and an open position, and a plurality of pads with a totally rounded outer shape. Each of the pads is mounted on each movable portion of the arms so as to be rotatable about a radial axis relative to the tool body according to the arm movement between the closed position and the open position.
