Publication number: 20080071323Abstract: Aspects of the invention relate to intracranial electrodes and methods for implanting and using intracranial electrodes. In one particular example, an intracranial electrode includes a shaft having a distal contact surface adapted to electrically contact a surface of a patient's brain, a head associated with the shaft, and threads adapted to fix the electrode with respect to the patient's skull. This electrode may have an adjustable length adapted to change a contact force of the distal contact surface against the surface of the brain by adjusting the length of the electrode.Type: ApplicationFiled: November 21, 2007Publication date: March 20, 2008Inventors: David Lowry, Bradford Gliner, Kent Leyde, Ben Clopton, Jay Miazga, Chris Genau

Patent number: 7320152Abstract: A hinge assembly includes a main member having a main cam member and a bore extending generally along an axis of rotation. A pivot member, fixed to an end of a shaft extending through the bore, includes a pivot cam member and is rotatable with respect to the main member. At least one torque element is rotatably engaged with the shaft and is substantially rotationally fixed with respect to the main member. The at least one torque element imparts a first frictional resistance to the shaft with rotation of the shaft in a first direction and a second frictional resistance to the shaft with rotation of the shaft in a second direction. The first frictional resistance is greater than the second frictional resistance. Interaction of the main cam member with the pivot cam member assists in maintaining the hinge assembly in at least first and second positions.Type: GrantFiled: July 22, 2005Date of Patent: January 22, 2008Assignee: Southco, Inc.Inventors: David A.

Publication number: 20050262850Abstract: A flow distributor for mounting in an inlet of a heat exchanger includes a nose cone and one or more diverting rings. The nose cone is aerodynamically shaped to divert impingent gas flow around the nose cone. A first diverting ring is spaced outwardly from the nose cone and can be oriented such that at least a portion of the gas flow diverted by the nose cone is redirected into the wake of the nose cone. A second diverting ring can be spaced outwardly from the first diverting ring and can be oriented to divert gas flow impingent thereon. Struts connect the nose cone and one or more rings. Refractory on the wall of the inlet is shaped to reduce the recirculation at the outer perimeter thereof. The flow distributor is installed in the inlet with refractory to achieve substantially equal flow across the tube sheet of the heat exchanger.Type: ApplicationFiled: January 24, 2005Publication date: December 1, 2005Applicant: Knighthawk EngineeringInventors: Clifton Knight, David Lowry, Judeth Corry, Kenneth Williams

Patent number: 6871384Abstract: The present invention relates to an assembly for rotatably mounting a display unit to a surface for movement between a first angular position adjacent the surface, a second angular position spaced from the surface and a range of third angular positions spaced from the second angular position. A first pintle secured to a first hinge mount is rotatably connected to a first hinge bracket. A first friction element secured to the first hinge bracket imparts a first resistive friction to the first pintle. A first detent mechanism secured to the first hinge bracket releasably secures the first pintle in the second angular position and imparts a second resistive friction to the first pintle when the first pintle is rotated through the range of third angular positions. The display unit rotates in a controlled manner from the first angular position to the second angular position due to a gravitational force.Type: GrantFiled: May 10, 2002Date of Patent: March 29, 2005Assignee: CEMA Technologies, Inc.Inventors: Eugene Novin, David A.

Patent number: 6588062Abstract: A hinge assembly for rotatably coupling a first member to a second member. A cylindrical pintle is secured to the second member. A friction element secured to the first member includes first and second cylindrical walls that wrap at least substantially circumferentially around the pintle in opposing first and second directions, respectively, providing equal resistance to relative rotation therebetween in both directions. A protuberance extends radially from the pintle, into a corresponding slot in at least one of the cylindrical walls, and engages an end of the slot when the first member and second member achieve a first predefined angular relationship, the friction element storing energy from relative movement between the friction element and pintle when the protuberance is engaged at the slot end.Type: GrantFiled: September 11, 2001Date of Patent: July 8, 2003Assignee: CEMA Technologies, Inc.Inventors: Eugene Novin, David A.
