Patent number: 6371067Abstract: A starter circuit provides capacitor-assisted energization of a vehicle's starter motor and prevents damage to capacitors in the circuit. The circuit includes a battery, a capacitor pack and a power control switch in the line connecting the pack to the motor and battery. The starter circuit includes a regulator for limiting current flow from the battery to the pack to a selected rate, the regulator being connected between the battery and the pack in parallel with the power control switch. A regulator switch is between the regulator and the capacitor pack. The starter circuit has a control circuit for selectively opening and closing the switches in response to a voltage level of the pack. The control circuit detects the voltage level of the pack, opens the power control switch when the voltage level falls below a predetermined threshold and simultaneously closes the regulator switch.Type: GrantFiled: October 26, 2000Date of Patent: April 16, 2002Assignee: The United States of America as represented by the Secretary of the ArmyInventors: John J.

Patent number: 6215310Abstract: A mechanism for testing electrical components in an ignition system of a diesel engine includes a metal jacket having receptacles passing through the jacket and also includes glow plugs fitting in the receptacles. The jacket has an inlet to admit water or other fluid from a pressurized source and also has an outlet to permit the fluid to escape from the jacket. The fluid flows through the jacket and thereby cools the receptacles, jacket and glow plugs. The testing mechanism includes a valve for metering the rate of flow of fluid into the jacket, the rate of flow being kept at a rate sufficient to prevent the jacket's temperature from exceeding a predetermined level. The glow plugs are connected to an electrical power source such as a battery, and a control circuit connected to the electrical power source and the plugs governs the cycle during which the plugs are electrically heated and then permitted to cool.Type: GrantFiled: June 18, 1999Date of Patent: April 10, 2001Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Paul A. Petrovich, John J. Schmitz, A. David Stormer

Patent number: 6164258Abstract: A starting controller for a diesel engine. The controller has a microprocor that will provide a current to the glow plugs until they are heated to the desired operating temperature and will then distribute sequential pulses to the individual plugs until the engine reaches the desired operating temperature. The system can have a latching circuit that will prevent the preglow cycle from being reinitiated until the glow plugs have been allowed to cool to a level where reinitiation will not represent a substantial degrading effect on the glow plugs.Type: GrantFiled: June 18, 1999Date of Patent: December 26, 2000Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Paul A. Petrovich, John J. Schmitz, A. David Stormer, Jack G. Rodgers

Patent number: 5715902Abstract: A retrofit mechanism adapts a pre-existing manually steered vehicle for b manual and powered remote steering control. The mechanism's steering control subassembly mounts to a bridge of a rigid adaptor assembly fixed to the vehicle's frame. A control subassembly post passes rotatably through a web of the adaptor's bridge. The post is rotated by a motorized steering actuator mounted to a side of the bridge. A symmetric wing fixed to the post pivotally connects with two rods, which themselves pivotally connect an adapter element on the steering column. The rods lie on opposite sides of, and equidistantly from, a line extending from the central axis to the steering column axis. The wing, rods and adapter element cooperate to achieve nonbinding rotation of the vehicle's steering column within a sleeve surounding the column.Type: GrantFiled: January 29, 1996Date of Patent: February 10, 1998Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Paul A.

Patent number: 5644952Abstract: A manual braking mechanism is adapted for manually overridable remote conl. The mechanism is disposed in a generally planar region forward of a vehicle's handle bar that does not interfere with the vehicle body or a human vehicle driver. The mechanism includes a base plate releasably clamped to the vehicle's handle bar and a housing fixed on the base plate. A brake cylinder in the housing connects to a control lever swingable on the base plate about a lever axis, and the cylinder's reaction force biases the lever toward a brake releasing position. A link pivots on the plate at the lever axis, has a hinge connection remote from the lever axis and has a carrier closer to the lever axis to the hinge connection. The carrier cammingly rotates the lever as the link swings on the lever axis. The mechanism has a frame whose first leg connects to the base plate at the lever axis and the frame's second leg is releasably clamped to the handle bar.Type: GrantFiled: January 29, 1996Date of Patent: July 8, 1997Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Paul A.

Patent number: 5632500Abstract: An adapter mechanism converts a manual throttle control to a powered manuy overidable throttle control. The manual control has a housing element, a post rotatable in the housing element and a control lever connected to the post. A first rotor plate engaged by the lever swings on the post to rotate a second rotor plate in one direction so as to translate a cable. The manual control has a return spring biassing the second plate in another direction toward a position where the cable closes the throttle. The adapter mechanism has a block-like cap on the housing element and the cap has a cavity open to the housing element. An actuator motor on the cap rotates a paddle in the first and second directions. A flange of the paddle engages a tab of the first rotor plate such that the paddle's rotation in the first direction moves the rotor elements but the paddle's rotation in the second direction exerts no force on the rotor elements.Type: GrantFiled: January 29, 1996Date of Patent: May 27, 1997Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Paul A.
