Patent number: 8761967Abstract: Methods, systems, and devices for determining system/device configuration and setting a mode of operation based on the determined configuration. An air vehicle processor: (a) receives a component information set of at least one external component; (b) determine a mode of operation, by the processor having a current mode of operation setting, based on the received component information and at least one of: an initial mode of operation setting and the current mode of operation setting; (c) determines whether all of the one or more received component information sets match a configuration requirement; (d) transitions to a flight-ready status if the determination is a conjunctive match; and (e) transition to a reset status if the determination is not a conjunctive match.Type: GrantFiled: May 23, 2012Date of Patent: June 24, 2014Assignee: Aerovironment, Inc.Inventors: Christopher E. Fisher, Marc L. Schmalzel, Steven Chambers, Justin B. McAllister

Patent number: 7244119Abstract: Compact low NOx gas burner apparatus and methods for discharging fuel gas and air mixtures into furnace spaces wherein the mixture is burned in folded flame patterns and flue gases having low NOx content are formed are provided. A burner apparatus of the invention is basically comprised of a housing having a burner tile attached thereto and means for introducing air therein. The burner tile has an opening therein with a wall surrounding the opening which extends into a furnace space. The exterior sides of the wall are divided into sections by radially positioned baffles with alternate sections having the same or different heights and slanting towards the opening at the same or different angles. Primary fuel gas mixed with flue gases and air is discharged through the burner tile. Secondary fuel gas is discharged adjacent to the external slanted wall sections whereby the secondary fuel gas mixes with flue gases in the furnace space.Type: GrantFiled: February 10, 2004Date of Patent: July 17, 2007Assignee: John Zink Company, LLCInventors: I-Ping Chung, Jesse Steven Chambers, Carol Ann Schnepper, Roger L. Poe, Jaiwant D. Jayakaran, Richard T. Waibel, Michael G. Claxton, Marianne Zimola, Darin Robert Foote

Publication number: 20070007051Abstract: An advanced control for a powered hand truck. The powered hand truck includes an electric motor, a power source, a programable motor controller, and a transaxle, which are adaptable to existing hand trucks, or may be integrated into a new powered hand truck. The motor controller controls the motor to provide consistent speed independent of load weight or incline, and further provides regenerative braking. The advanced control may be wired or wireless and provides a touch sensitive circuit to command stop if the operator is not holding the handle, and an electronic potentiometer. The wireless control further includes a unique code for validating speed commands and initiates deceleration if the control signal is lost.Type: ApplicationFiled: August 28, 2006Publication date: January 11, 2007Inventor: Steven Chambers

Publication number: 20050155799Abstract: A powered hand truck for assisting in the movement of objects. The powered hand truck includes an electric motor, a power source, a programable motor controller, and a transaxle, which are adaptable to existing hand trucks, or may be integrated into a new powered hand truck. The transaxle includes a differential allowing easy maneuvering of the hand truck. Power is provided by replaceable/rechargeable batteries. The motor controller controls the motor to provide consistent speed independent of load weight or incline, and further provides regenerative braking. The motor controller also includes diagnostics communicated through a display mounted to the hand truck.Type: ApplicationFiled: January 20, 2004Publication date: July 21, 2005Inventor: Steven Chambers
