Patent number: 11054394Abstract: A computer-implemented method is described for detecting, identifying and locating an object feature in a ferromagnetic object. At least one hardware processor executes program instructions to: define a planned scan trajectory for scanning the ferromagnetic object with a sensor array comprising a plurality of magnetometer sensors, measure magnetic fields of the ferromagnetic object with the sensor array along an actual scan trajectory at locations adjacent to the ferromagnetic material to produce object scanning data representing magnetic characteristics of the ferromagnetic object along the actual scan trajectory. The actual scan trajectory includes deviation motion of the scanning array from the planned scan trajectory.

Patent number: 7132173Abstract: Braze and electrode wire assemblies, e.g., used with an implantable microstimulator, include a wire welded in the through-hole of an electrode, which electrode is brazed to a ceramic case that is brazed to a metal ring that is welded to a metal can. The braze joints are step or similar joints that self-center the case, provide lateral support during braze assembly, and provide increased surface area that prevents braze material from exuding from the joints. The end of the ceramic case that is brazed to the metal ring need not be specially machined. The shell has a reference electrode on one end and an active electrode on the other, and is externally coated on selected areas with conductive and non-conductive materials.Type: GrantFiled: June 27, 2003Date of Patent: November 7, 2006Assignee: Advanced Bionics CorporationInventor: Jay Daulton

Patent number: 6951125Abstract: A system and method is disclosed for aligning an integrated circuit die on an integrated circuit substrate. A plurality of deposits of deformable material are placed on the substrate where the integrated circuit die is to be aligned. In one advantageous embodiment a stamping tool is indexed to a first tooling hole and to a second tooling hole in the substrate. The stamping tool imprints the deposits of deformable material to a tolerance of less than one hundred microns with respect to the first and second tooling holes. The imprinted portions of the deposits a form a pocket for receiving the integrated circuit die. This enables the integrated circuit die to be precisely aligned on the substrate in three dimensions.Type: GrantFiled: January 31, 2002Date of Patent: October 4, 2005Assignee: STMicroelectronics, Inc.Inventors: Harry Michael Siegel, Anthony M.

Publication number: 20040149809Abstract: A method of connecting a metal (1) with a ceramic material (2) comprises the steps of providing a through-hole (3) in the ceramic material and positioning the metal (1) to be connected to the ceramic material (2) proximate to the ceramic material (2) with the through-hole (3). Subsequently, the metal (1) is melted (7) proximate to the through-hole (3). A pressure difference prevails between the side of the ceramic (2) remote from the metal and the side of the metal (1) remote from the ceramic material (2). A larger pressure prevails at the side of the metal (1) remote from the ceramic material (2). The pressure difference causes the melt (7) to be pressed into the through-hole (3) in the ceramic material (2). The through-hole (3) has such a shape that, after solidification, the solidified material (14) and the through-hole (3) have a complementary locking form.Type: ApplicationFiled: November 24, 2003Publication date: August 5, 2004Inventors: Johannus Wilhelmus Weekamp, Durandus Kornelius Dijken, Theodorus Johannes Maria Jacobus Van Gennip

Patent number: 6754945Abstract: A method of forming a stress isolating joint on a dump body of on an off-highway rubber-tired haulage vehicle includes providing a first plate having an elongated edge, a top side, and a face, and providing a second plate including an elongated edge. Overlapping the first and second plates to define a widened seam bounded at least in part by the elongated edges of the respective plates, and welding along the elongated edge of the first plate to join the elongated edge of the first plate to an adjacent surface of the second plate. The weld and at least a portion of the second plate disposed along the widened seam cooperate to permit the second plate to apply a resisting load to the face of the first plate in response to the application of a load against an opposing face of the first plate.Type: GrantFiled: March 27, 2003Date of Patent: June 29, 2004Inventors: Steven J.

Patent number: 6711803Abstract: The present invention enables to firmly assemble a steel-frame structure. To form a steel-frame structure or to join two steel members being reinforcing members thereof, a slip-proof surface having one or plural concentric higher parts and grooves is formed on the joined surface of one side or both sides of the steel members, and these two steel members are clamped by a connecting member that passes through connecting holes in the state where the first and the second slip-proof surfaces are mutually engaged or not engaged. Thus, joining force between the joined surfaces is increased.Type: GrantFiled: August 23, 2000Date of Patent: March 30, 2004Assignee: Takashima CorporationInventor: Kiyokazu Kobayashi

Patent number: 6708870Abstract: The method forms a sputter target assembly by attaching a sputter target to an insert and applying a bond metal layer between the insert and a backing plate. Then pressing the insert and backing plate together forms a solid state bond with the bond metal layer, attaches the insert to the backing plate and forms at least one cooling channel between the insert and the backing plate. A filler metal secures the outer perimeter of the insert to the backing plate in order to eliminate leakage from the cooling channel during sputtering of the sputter target.Type: GrantFiled: May 24, 2002Date of Patent: March 23, 2004Assignee: Praxair S.T.
