Publication number: 20070283839Abstract: A modular friction drive system and method for use with a palletized conveyor. The drive system includes drive assemblies located at opposite sides of both a load end and unload end of the palletized conveyor. Each drive assembly comprises at least one drive unit and at least on take-up unit, which are connected by a drive belt. One or more idler units may reside between the drive unit(s) and take-up unit(s). Each drive assembly is provided with an actuating means for pressing the drive belt tightly against the side walls of the conveyor pallets. Each of the drive unit, take-up unit, and idler unit is preferably modular in nature and can, therefore, be added to or removed from a drive assembly independently of the other unit(s).Type: ApplicationFiled: March 31, 2006Publication date: December 13, 2007Applicant: Honda Motor Co., Ltd.Inventors: Samuel Bartlett, David Betz, David Dillard, Jason Harrison, Wayne Hemmelgarn, Jerry Maynard, Norm Schrake

Patent number: 7168549Abstract: A conveyor system incorporating a plurality of lift assemblies, wherein the lift assembly includes a platform for supporting an article during manufacture. A cylinder assembly is used for vertically supporting the platform and for moving the platform vertically between any one of a plurality of vertical height positions. A control system is used for actuating the cylinder assembly. The control system monitors the movement of the article along the assembly line, and includes predetermined height/position routines that are used to actuate the cylinder assembly and thereby move the platform vertically to a predetermined platform height corresponding to the location of the article on the line. In this way, the platform heights are selected to provide an ergonomic benefit in performing each operation.Type: GrantFiled: January 11, 2005Date of Patent: January 30, 2007Assignee: Honda Motor Co., Ltd.Inventors: Jason C.

Publication number: 20050251143Abstract: A soft tissue fixation kit comprises a flexible implant and an insertion tool for the implant. The implant is formed of a flexible biocompatible material and a rigid bone biocompatible fixation device. The insertion tool carries the implant percutaneously for insertion into selected soft tissue and bone. When the insertion tool is removed the implant is left in the selected tissue and anchored to the bone.Type: ApplicationFiled: May 5, 2004Publication date: November 10, 2005Inventor: David Dillard

Patent number: 6857371Abstract: The two-payload decoy device has a square outer case, containing a manifold/delay body assembly, a round payload assembly, and a square payload assembly. The square outer case is closed with an end cap. The manifold/delay body assembly is attached to the round payload assembly, which rests against the square payload assembly. Firing a standard impulse cartridge ignites a booster pellet and delay element in the manifold/delay body assembly. Gases flow through openings in the manifold/delay body assembly and down the corner cavities between the round payload assembly and the square case, pushing the square piston against the square payload, which separates the end cap from the case and ejects the square payload. The delay element burns for a specific time, and then ignites a round payload expulsion charge, which creates gases that push the round piston against the round payload, which dislodges a retaining ring, and ejects the round payload.Type: GrantFiled: June 19, 2003Date of Patent: February 22, 2005Assignee: The United States of America as represented by the Secretary of the NavyInventors: Donald Lagrange, Douglas Shulte, Robert Barker, Charles Howard, Richard Hall, David Dillard

Publication number: 20050033344Abstract: An intra-bronchial device placed and anchored in an air passageway of a patient to collapse a lung portion associated with the air passageway. The device includes a support structure, an obstructing member carried by the support structure that reduces ventilation to the lung portion by preventing air from being inhaled into the lung portion, and at least one anchor carried by the support structure that anchors the obstruction device within the air passageway. The anchor may engage the air passageway wall by piercing or friction, include a stop dimensioned for limiting the piercing of the air passageway wall, and may be releasable from the air passageway for removal of the intra-bronchial device. The anchors may be carried by a peripheral portion of the support structure, or by a central portion of the support structure. The obstructing member may be a one-way valve.Type: ApplicationFiled: September 3, 2004Publication date: February 10, 2005Inventors: David Dillard, Hugo Gonzalez, Seung Yi, Lauri DeVore, Mia Park, Dean Corcoran, Jenni Rimbaugh, Clifton Alferness

Patent number: 6578431Abstract: A method and apparatus for determining bulk material constants such as Poisson's ratio and the ratio of shear modulus to bulk modulus for elastomeric materials, including, but not limited to elastomers, rubbers, gels and sealants is disclosed. The bulk material properties are determined by measuring the pressure change of the elastomeric material when the elastomeric material is subjected to an applied pressure. The changes in the bulk material property due to temperature or a the addition of a diluent may also be determined. The apparatus includes a container that holds the elastomeric material. A pressure sensor is located in the container and is positioned to measure the pressure of the elastomeric material. The signal from the pressure sensor along with the applied pressure is used to determine a bulk material property such as Poisson's ratio or the ratio of shear modulus to bulk modulus for the elastomeric material.Type: GrantFiled: April 3, 2001Date of Patent: June 17, 2003Assignee: Virginia Tech Intellectual Properties, Inc.Inventors: David A. Dillard, Didier Lefebvre, Jang-Horng Yu

Patent number: 6156048Abstract: An atherectomy device that may reduce the risk of damage to a vessel wall. One rotatable atherectomy burr has a recessed material removal portion lying between less abrasive proximal and distal shoulders. The shoulders can have a straight, rounded or elliptical taper. The shoulders can perform a cam action when the burr is canted is a vessel, as when passing the burr and guide wire through a tortuous, stenosed vessel path. The shoulders act to align the burr with the path through the vessel, presenting the less abrasive shoulders to the vessel wall while presenting the abrasive portion to a stenosis.Type: GrantFiled: August 2, 1999Date of Patent: December 5, 2000Assignee: SCIMED Life Systems, Inc.Inventors: Edward Wulfman, Lucas Gordon, Robert Barry, Brandon Shuman, David Dillard, Verivada Chandrasekaran
