Patent number: 8091656Abstract: A method and apparatus for reducing or eliminating the energy required by an operator of a delivery cart to start the cart moving in a predetermined direction at a predetermined speed as well as to recover some or all of the energy used to start the cart moving. The apparatus includes a cart, a drive wheel, a motor for driving the drive wheel, and a rechargeable energy source to power said motor where the rechargeable energy source is recharged during normal, unpowered movement of the cart. The method includes charging a power source while moving the cart, actuating a directional button to initiate movement in a desired direction, energizing a clutch to couple the motor to the driven wheel, energizing the motor to drive the driven wheel in the desired direction. After a predetermined time period, set by a run timer, the clutch is decoupled while the motor remains activated, and thereafter the motor is deactivated.Type: GrantFiled: July 14, 2010Date of Patent: January 10, 2012Assignee: Honda Motor Co., Ltd.Inventors: Brent C.

Patent number: 7367220Abstract: A method for pressure testing an engine to detect possible oil seal leaks. The engine is charged with a predetermined pressure while air pressure is also applied to an exhaust gas recirculation (EGR) valve intake port to offset leakage inherent in the EGR valve. Thereafter, a pressure drop in the engine pressure is used to determine whether an oil seal leak may be present. Applying pressurized air to the EGR valve intake port compensates for EGR valve leakage and prevents the EGR valve leakage from masking possible oil seal leaks, thereby making the system more sensitive to such potential oil seal leaks.Type: GrantFiled: January 5, 2006Date of Patent: May 6, 2008Assignee: Honda Motor Co., Ltd.Inventors: Heather W. Thomas, Chuck Hoke, Brent C. Rankin

Patent number: 7367219Abstract: A method and apparatus for developing a test for determining if an engine has oil seal leaks. The engine is charged with a predetermined pressure of air and monitored by a leak tester. A digital valve is set to provide a certain leak rate based upon signals received from a digital valve controller. Thereafter, based upon signals received from a PC and a main control unit, a variety of trials are completed. The results and programs are stored in the PC. Results of the trials allow an optimized testing program to be selected that would be best suited for use on a manufacturing assembly line.Type: GrantFiled: December 28, 2006Date of Patent: May 6, 2008Assignee: Honda Motor Co., Ltd.Inventor: Brent C.

Patent number: 7347087Abstract: A system and method for testing partially assembled engines for possible oil leaks. The system includes engine pressurizing devices that are automatically controlled by a controller according to a predetermined control program based upon the engine model type being tested. The pressurizing devices introduce pressurized air into the engine oil system. A leak testing unit monitors the pressurized engine for pressure drops indicative of an oil seal leak. Air pressure leaks resulting from inherently air-porous EGR valves are compensated for by an EGR compensating unit, which provides pressurized air to an intake side of the EGR valve. The flow of pressurized air through the EGR compensating unit is monitored to determine whether there is a problem with the EGR valve.Type: GrantFiled: January 10, 2006Date of Patent: March 25, 2008Assignee: Honda Motor Co., Ltd.Inventors: Brent C. Rankin, Heather W. Thomas, Chuck Hoke

Patent number: 6492900Abstract: A sensor device is used for sensing position of a movable component. The sensor device can be applied to multiple applications. For example, proper alignment between a shifter spline and a shifter position sensor of a transmission assembly can be confirmed by applying the sensor device of the present invention to confirm alignment of the transmission shifter with a transmission shifter position sensor during transmission assembly. A rotary sensor converts angular movement to a proportional electrical output. A converter then converts the proportional electrical output to an input which can be read. The location of the movable component is then determined, and displayed.Type: GrantFiled: February 19, 2002Date of Patent: December 10, 2002Assignee: Honda of America Manufacturing, Inc.Inventor: Brent C.

Patent number: 6448778Abstract: The present invention is an assembly line testing apparatus and method for automatically verifying proper connectivity of a plurality of components to a wiring harness within an article of manufacture, such as a vehicle engine, by electrically determining whether a closed circuit loop is formed with each component through two respective nodes of the wiring harness. A micro-controller controls application of a test voltage signal at a first node of the wiring harness to be coupled to one node of a component. The micro-controller then determines whether such a test voltage signal appears on a second node of the wiring harness to be coupled to the other node of the component to determine whether the component is properly connected to the wiring harness. In addition, the micro-controller determines and outputs an identification of any of the plurality of components that is not properly connected to the wiring harness.Type: GrantFiled: January 29, 2001Date of Patent: September 10, 2002Assignee: Honda of America Mfg., Inc.Inventor: Brent C.

Patent number: 6274829Abstract: A device is provided for allowing detection of a switch closure across an air gap between components. The device comprises a wireless inductive coupled switch designed for use with any suitable proximity sensor. The switch and sensor transmit a switch closure at a closable switch across the air gap. When the wireless inductive coupled switch is moved into the sensing range of the inductive proximity sensor, the ferrite core portion of the inductive coupled switch and the coil surrounding the ferrite portion are inductively coupled by the alternating field generated by the inductive proximity sensor. The alternating magnetic flux lines of the inductive proximity sensor move back and forth through the ferrite core portion and the coil. As long as the closable switch is open, no current is induced into the coil.Type: GrantFiled: March 2, 2000Date of Patent: August 14, 2001Assignee: Honda of America Manufacturing, Inc.Inventor: Brent C.
