Patent number: 11761698Abstract: A defrost cycle control assembly includes a first sensor that is configured to measure a temperature adjacent a top portion of an outdoor heat exchanger of a heat pump, a second sensor that is configured to measure a temperature adjacent a bottom portion of the outdoor heat exchanger, and a third sensor that is configured to measure an ambient temperature. Further, the defrost cycle control assembly includes a controller that is configured to initiate a defrost cycle of the heat pump based on the temperature adjacent the top portion and the ambient temperature when said temperatures indicate formation of frost at the top portion of the outdoor heat exchanger where the first sensor is disposed. The controller is configured to terminate the defrost cycle when the temperature at the bottom portion reaches a termination temperature which indicates that the frost on the outdoor heat exchanger has melted.Type: GrantFiled: June 28, 2021Date of Patent: September 19, 2023Assignee: RHEEM MANUFACTURING COMPANYInventors: Aniket R. Kalambe, Walter R. Lowrimore, Neil D. Hurt, Michael Andrews, Randy Foster

Publication number: 20150058195Abstract: A system and method for monitoring an equity rights transaction for strategic investors in a securities exchange. More specifically, a technological infrastructure which monitors an equity rights program in which units representing the right to acquire equity in an exchange or an exchange's parent holding company are issued to a participating member in exchange for a cash payment and the achievement of certain volume thresholds on the exchange over a specified period.Type: ApplicationFiled: August 21, 2014Publication date: February 26, 2015Applicant: Miami International Securities Exchange, LLCInventors: Barbara J. COMLY, Thomas P. Gallagher, Douglas M. Schafer, JR., Shelly Brown, Randy Foster

Publication number: 20070142148Abstract: A belt tensioner includes a support housing at least in part defining a spring cavity and an arm pivotally attached to the support housing. A spring is located in the spring cavity and is operatively connected to the arm and the support housing to bias the arm about a pivot axis toward an unloaded position relative to the support housing. A damping member includes a hub and deflectable, force-applying elements that are connected to and spaced apart about a periphery of the hub. The force-applying elements are biased toward a contact surface of the arm to apply a frictional force between the contact surface and the force-applying elements to impede rotation of the arm relative to the support housing.Type: ApplicationFiled: November 22, 2005Publication date: June 21, 2007Inventors: Robert Joslyn, James Quintus, Randy Foster

Publication number: 20070102227Abstract: A first vehicle power steering system includes a twistable steering torsion bar, a magnet, a Hall sensor, and a valve. The steering torsion bar has a first end fixedly connected to a vehicle steering wheel. The magnet is movable in a first and an opposite second longitudinal direction with respect to the steering torsion bar and is constrained to move in the first longitudinal direction when the steering wheel is turned to the right by a driver and is constrained to move in the second longitudinal direction when the steering wheel is turned to the left by the driver. The Hall sensor has an output and is positioned proximate the magnet. The valve is operatively connected to the output. A second vehicle power steering system includes a twistable steering torsion bar, a ring-magnet support cylinder, a ring-magnet assembly, a ball-and-ramp assembly, a spring, a Hall sensor, and a valve.Type: ApplicationFiled: November 7, 2005Publication date: May 10, 2007Inventors: Joey Edson, Klaus Engel, Randy Foster, Richard Meckstroth

Publication number: 20070017733Abstract: A vehicle power steering system includes a sweep magnet, at least one Hall sensor, and at least one hydraulic-power-steering-system valve. The sweep magnet is fixedly connected to a first end of a twistable steering torsion bar wherein the first end is fixedly connected to a vehicle steering wheel. The at-least-one Hall sensor is fixedly connected to a second end of the steering torsion bar. The at-least-one Hall sensor has an output and is positioned proximate the sweep magnet such that the output is a function of steering wheel torque when the vehicle steering wheel is turned by a driver. The at-least-one hydraulic-power-steering-system valve is operatively connected to the output.Type: ApplicationFiled: June 13, 2005Publication date: January 25, 2007Inventors: Joey Edson, Klaus Engel, Randy Foster, Aleksandar Jankovic, Richard Meckstroth

Publication number: 20060053790Abstract: An automotive starting system includes an accumulator, a hydraulic motor, and an engine controller. The accumulator is adapted for holding a charge of pressurized fluid. The hydraulic motor has a fluid input operatively connected to the accumulator and has an output shaft operatively connected to an internal combustion engine of an automotive vehicle. The engine controller shuts off the engine if an idle engine condition exists and restarts the engine using the hydraulic motor following an idle engine shut-off if a predetermined engine-start condition exists. A method for starting an internal combustion engine of an automotive vehicle includes having the engine controller shut off the engine if an idle engine condition exists and thereafter having the engine controller restart the engine using the hydraulic motor if a predetermined engine-start condition exists.Type: ApplicationFiled: September 13, 2004Publication date: March 16, 2006Inventor: Randy Foster

Publication number: 20050261094Abstract: A tensioner for a power transmitting belt is provided having a base, an arm pivotably attached to the base, a pulley rotatably attached to the arm and a spring operatively connected to the arm and the base for urging the arm in direction to tension the belt. A hydraulic strut is pivotably attached to the base and the arm to restrict the movement of the arm through asymmetric fluid damping. The hydraulic strut includes a hydraulic cylinder filled with magnetorheological fluid, a piston rod axially mounted through the cylinder and a piston mounted on the piston rod to divide the cylinder into first and second fluid chambers. The strut further includes a fluid flow path between the first and second fluid chambers, a check valve in the fluid flow path to provide asymmetric fluid flow and a coil that is operable to generate a magnetic field across the fluid flow path when energized.Type: ApplicationFiled: May 18, 2004Publication date: November 24, 2005Inventors: Randy Foster, Richard Meckstroth
