Patent number: 9201689Abstract: A method and system for software emulation of hardware support for multi-threaded processing using virtual hardware threads is provided. A software threading system executes on a node that has one or more processors, each with one or more hardware threads. The node has access to local memory and access to remote memory. The software threading system manages the execution of tasks of a user program. The software threading system switches between the virtual hardware threads representing the tasks as the tasks issue remote memory access requests while in user privilege mode. Thus, the software threading system emulates more hardware threads than the underlying hardware supports and switches the virtual hardware threads without the overhead of a context switch to the operating system or change in privilege mode.Type: GrantFiled: April 22, 2011Date of Patent: December 1, 2015Assignee: Cray Inc.Inventors: Steven L. Scott, Gregory B. Titus, Sung-Eun Choi, Troy A. Johnson, David Mizell, Michael F. Ringenburg, Karlon West

Publication number: 20090008901Abstract: Improved handles are provided for a wheelchair brake lever and legrest release lever of a wheelchair. Each handle has a first end with a slot for receiving the respective lever, and a second end extending angularly from the first end so as to be nonplanar and noncoaxial with the respective levers. The handles include ribs or textured surfaces for improved tactile feel, and are made of brightly colored material for high visibility. Increased size, feel and visibility of the handles make them easier to locate for a person sitting in the wheelchair.Type: ApplicationFiled: July 2, 2007Publication date: January 8, 2009Inventors: Bette McCombs Guzman, Troy A.

Patent number: 7412807Abstract: A cabinet dryer door includes a truss attached to the door to establish seal compression for adequate sealing of the door against the drying cabinet. The inner door has spacers molded into the inner door. The truss cooperates with the spacers to bias the door against the seal. The drying cabinet may utilize a pair of doors with at least one having a truss that establishes a seal compression in both of the doors. The truss is joined to the inner door by a screw located in the center of the truss. The method has the step securing a truss member to the door and curving the door to create a biasing force.Type: GrantFiled: July 16, 2004Date of Patent: August 19, 2008Assignee: Whirlpool CorporationInventors: Troy A.

Patent number: 7137211Abstract: A clothes drying cabinet is provided with a shaker assembly including a bar suspended in the cabinet for supporting clothes hangers. A motor is mounted adjacent the bar and has a drive shaft. A drive weight is eccentrically mounted to the drive shaft of the motor so that upon actuation of the motor, the drive weight imparts a shaking motion to the bar so as to facilitate removal of wrinkles from the clothing on the hangers. A ballast weight may also be provided in the shaker assembly so as to evenly distribute the energy from the eccentric weight regardless of the weight of the clothes hanging on the bar.Type: GrantFiled: August 18, 2004Date of Patent: November 21, 2006Assignee: Maytag CorporationInventors: Troy A. Johnson, Dean L. Schaffran

Patent number: 6507967Abstract: A control device for a laundry appliance includes a member which need only be manually shifted through a limited range of travel, from a neutral position to which the control member is biased, in either of first and second opposing directions, to establish a desired cycle and to adjust an operational time for the cycle. The control member is provided with numerous movable contacts which are interposed between fixed contacts. Shifting of the control member a limited amount in either direction will function to engage a single pair of the contacts, while shifting the control member a further amount in the same direction causes another pair of the contacts to become engaged. In this manner, the contacts are paired to slowly increase or decrease the operational time and to also select either the next or previous operational cycle. User feedback of the selected setting is preferably provided through the use of a illuminated indicator that shifts around a track adjacent operational indicia.Type: GrantFiled: March 16, 2001Date of Patent: January 21, 2003Assignee: Maytag CorporationInventor: Troy A.

Patent number: 6481246Abstract: The air pressure sensor of the present invention functions to control the water level in a washing machine tub and to vary the fill volume relative to the clothes load. The sensor or switch is mounted on the drain pump on the base of the washing machine cabinet, so as to be independent from the washing machine tub. An air dome extends between the switch and the water inlet line of the pump. The switch is set to be actuated at a predetermined pressure. As the water level increases in the tub, the air pressure within the air dome increases, until eventually the switch is actuated. The switch is mounted directly to the air dome in an angular orientation, thereby minimizing or eliminating condensation problems in the switch. The switch will also be activated by water pressure, in the event of an air leak in the air dome, so as to preclude water overflow of the tub.Type: GrantFiled: July 19, 2000Date of Patent: November 19, 2002Assignee: Maytag CorporationInventors: Troy A. Johnson, Evan R. VandeHaar, Russell L. VanNorden, Ted L. Hansen

Patent number: 6129768Abstract: According to a method and apparatus for balancing a container using a closed system fluid balance ring for high rotational speed washing machines, the transfer of fluid is pulsed, allowing for a variable overall mass transfer rate while computation of the imbalance continues. Mass transfer continues until any significant imbalance is eliminated. The quasi-constant nature of this method allows for the resulting imbalance tolerances to be significantly lower. As the imbalance decreases, the mass transfer rate is varied accordingly.Type: GrantFiled: November 6, 1998Date of Patent: October 10, 2000Assignee: Maytag CorporationInventors: Troy A. Johnson, John E. Thomas

Patent number: 5979195Abstract: A sealing device is provided to bridge a gap defined between open frontal portions of inner and outer tubs of a horizontal axis washing machine in order to prevent foreign objects from getting into the outer tub from the inner tub through the gap and potentially clogging a pumping system of the machine. In the preferred form of the invention, the sealing device includes a first seal portion fixedly secured to a lower, inner wall portion of a cover attached to the outer tub and a flexible, second seal portion which extends toward and preferably slidably contacts a balance ring provided about the open frontal portion of the inner tub. In accordance with one embodiment, the sealing device is constituted by a brush member, with the second seal portion being defined by bristles of the brush member. In another embodiment, the sealing device is constituted by a plastic film having one longitudinal side secured to the outer tub cover and another longitudinal side in sliding contact with the balance ring.Type: GrantFiled: May 15, 1998Date of Patent: November 9, 1999Assignee: Maytag CorporationInventors: Gary D. Bestell, Troy A. Johnson, Louis R. Smothers, Theodore R. Van Drimmelen, Evan R. Vande Haar, William R. White

Patent number: 5974610Abstract: A counterbalance weight is provided for a laundry washing machine tub. The weight includes a weighted body securable to the tub with a foam impact-absorbing member mounted on the body in a position below the tub so as to absorb impact forces on the tub. The body of the counterbalance weight includes a pair of open slots adapted to receive bolts extending from the tub so as to slidably mount the counterbalance weight onto the tub. In an alternative embodiment, impact-absorbing members are provided on the bottom of a hung strut tub to absorb impact to the tub and to maintain the vibration-absorbing function of the strut springs.Type: GrantFiled: May 25, 1999Date of Patent: November 2, 1999Assignee: Maytag CorporationInventors: Troy A. Johnson, Greg K. Harmelink, Stephen D. Ostdiek
