Patent number: 9823279Abstract: A current sense resistor integrated with an integrated circuit die where the integrated circuit die is housed in a flip-chip semiconductor package includes a metal layer formed over a passivation layer of the integrated circuit die where the metal layer having an array of metal pillars extending therefrom. The metal pillars are electrically connected to a first leadframe portion and a second leadframe portion of the semiconductor package where the first leadframe portion and the second leadframe portion are electrically isolated from each other and physically separated by a separation of a first distance. The current sense resistor is formed in a portion of the metal layer spanning the separation between the first and second leadframe portions, the first and second leadframe portions forming terminals of the current sense resistor.Type: GrantFiled: August 4, 2015Date of Patent: November 21, 2017Assignee: Micrel, Inc.Inventor: Cameron Jackson

Publication number: 20170107893Abstract: A rotating suction wand for a cooler box screen including a hollow body for attaching to a suction hose. A first slot and at least a second slot are formed in the hollow body in fluid communication with an interior of the hollow body for facingly engaging a screen. The construction and arrangement of the slots redistributes suction force along the length of the wand in such a way as to compensate for differences in angular rotational speed of the wand at varying radial distances from the center of the wand as well as to overcome suction force reduction which normally occurs from the center to the ends of the wand. Consequently, debris is more effectively removed from the screen from the central regions of the wand to radially distal regions thereof.Type: ApplicationFiled: June 2, 2015Publication date: April 20, 2017Inventors: Raymond Samuel Trey Davenport, Cameron Jackson Ivey, David Paschal, Panos Tamamidis, Matthew John Gyenes, Mark Merkel, Shekhar Sarpotdar

Patent number: 6779605Abstract: A safety system controls the activation of one or more downhole tools by providing selective transmission of an activation signal or an energy stream. In a preferred embodiment, transmission of the activation signal or the energy stream is allowed after the tool has passed below a known pre-determined depth. A preferred safety system includes a first device in fixed relationship with the downhole tool and a second device fixed at the stationary location. The first device permits, after reaching the pre-determined depth, either (a) an initiation signal to reach an initiation device associated with a downhole tool upon or (b) the energy stream to reach a downhole tool. The second device positively engages the first device to provide an indication that the specified depth has been reached.Type: GrantFiled: May 16, 2002Date of Patent: August 24, 2004Assignee: Owen Oil Tools LPInventor: Cameron Jackson

Patent number: 6640899Abstract: A jarring tool uses a button member to control the jarring sequence used to free an object lodged in a well bore. A preferred tool includes an anvil having a sleeve portion adapted to enter a bore of a hammer. The button member allows selective entry of the anvil sleeve into the hammer bore. A preferred telemetry link includes two or more at least partially conductive members in a telescopic relationship for exchanging electrical signals with the object. The members extend and retract to accommodate length changes of the jarring tool. An exemplary jarring sequence includes a loading phase, a release phase, and a reset phase. In the loading phase, the button member prevents hammer movement toward the anvil. During the release phase, the button member allows the hammer to be propelled against the anvil. In the reset phase, the hammer and button returns to their initial positions.Type: GrantFiled: October 18, 2001Date of Patent: November 4, 2003Assignee: Core Laboratories, L.P.Inventors: Cory D.
