Patent number: 11981196Abstract: Ride-on equipment includes a pair of front wheels, a pair of rear wheels, a main frame, a subframe pivotally coupled to the main frame about a pivot axis, a power source, and a transaxle assembly. The power source is coupled to and supported by the main frame and includes a drive pulley. The transaxle assembly is configured to pivot with respect to the power source, is operably coupled to the pair of rear drive wheels, and includes at least one driven pulley. The drive pulley and the at least one driven pulley are operably coupled by a belt such that the at least one driven pulley of the transaxle assembly is configured to be driven by the drive pulley of the source via the belt.Type: GrantFiled: December 31, 2020Date of Patent: May 14, 2024Assignee: Briggs & Stratton, LLCInventors: Mark J. Melone, James F. Marshall, Richard Smith, Mark Lynch, Travis Rasch, Erik Slegelis, Steven J. Weber, Denis Oswald

Patent number: 10752190Abstract: The present invention is a power window sync switch for the windows of a vehicle that permits controlling all windows by a single active home or main control window switch. It permits the driver to move all window panels in the vehicle to the same position at the same time. The power window sync switch sends a signal to a micro-processor within the switch to indicate that the window position selected via the actuated switch is to be applied to all window panels simultaneously. The micro-processor within the switch may then proceed to actuate all window lift motors within the vehicle, causing movement of all window panels to the appropriate positions.Type: GrantFiled: August 6, 2019Date of Patent: August 25, 2020Inventor: Richard Oswald Neville Buckley

Patent number: 9718410Abstract: An assembly for releasably connecting a roof bar to a roof of a vehicle. The assembly includes a body which is affixed to the roof bar, a base which is affixed to the roof and has a receiving portion for receiving a portion of the body, a locking pin slidably engaged with the body and the base, and slidable along an axis between a locked position and an unlocked position. In the locked position, the locking in engages the body and the base. In the unlocked position, the locking pin engages the body or the base. The assembly also has an actuator movable along the axis to slide the locking pin between the locked position and the unlocked position, thereby selectively engaging the body with the base.Type: GrantFiled: November 4, 2015Date of Patent: August 1, 2017Assignee: Rhino Rack Australia Pty LimitedInventors: Richard Oswald Cropley, Christopher John Murty, Michael John Laybourne Hort

Patent number: 7502205Abstract: A control source and drivers for a thermal actuator fly height controlled heads in a disk drive system includes provisions for driving a heater element to dissipate various levels of power, and thus actuate the head by a desired amount, depending on whether the head is in a write mode or a read mode. Further, overshoot and undershoot are achieved as desired by providing initial values and equilibrium values and through the use of a control capacitor to provide a time constant to the drive signal to the heater element.Type: GrantFiled: June 3, 2004Date of Patent: March 10, 2009Assignee: Maxtor CorporationInventors: Tony Hurtado, Wentao Yan, Lin Guo, Chris Hawks, Don Brunnett, Thao Nguyen, Richard Oswald, Erhard Schreck
