Patent number: 11623683Abstract: In an exemplary embodiment, a test system is provided for testing a power steering system for a vehicle, the test system including a motor, one or more sensors, and a processor. The one or more sensors are configured to obtain sensor data pertaining to the motor. The processor is coupled to the one or more sensors and to the motor, and is configured to: determine, using the sensor data, a desired position of the motor for providing a desired amount of torque to the power steering system in order to reach one or more target behaviors: an inertia target, a spring target, a damper target, or a friction target for the power steering system; and provide instructions for the motor to move to the desired position for providing torque to the power steering system.Type: GrantFiled: June 25, 2021Date of Patent: April 11, 2023Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Jarred James Versical, Bo Yu, Ian Y.

Publication number: 20110219544Abstract: An oscillating bed includes a stand or base with spaced apart, head and foot upright members. A body supporting member generally defines the length and width of the bed and has a foot end and a head end defining a longitudinal axis and longitudinally extending rims along opposed sides with a curved surface extending lateral to the longitudinal axis between the foot end and the head end. The head upright member is pivotally attached to the head end and the foot upright member is pivotally attached to the foot end and supports the body supporting member relative to the stand for oscillatory movement. A rotary motor and drive apparatus are coupled to the body supporting member and convert rotary motion of the motor to oscillatory movement of the body supporting member about the longitudinal axis.Type: ApplicationFiled: February 16, 2011Publication date: September 15, 2011Inventors: Howard Johnston, Willard R.

Publication number: 20080305027Abstract: This invention relates to the preparation, functionalisation and use of a novel nano structured silicate, generally a calcium silicate which may be hydrated. It also relates to novel methods of producing nano structured silicates. The novel nano-structured silicate material comprises a calcium silicate in the form of platelets of about 5-10 nm thick and about 50-500 nm wide or wider stacked together in a poorly ordered framework type structure as illustrated in FIG. 1. The novel material can be prepared by reacting a calcium ion containing solution with a silicate containing solution under controlled conditions and then allowing the calcium silicate to age. The novel silicate has pores of a high volume and which are readily accessible. This provides a high oil absorption capacity and high surface area. Novel nano-structured silicate materials are produced by the invention having an oil absorption capacity up to 700 g.oil.100 g?1 silicate and a surface area up to 600 m2g?1.Type: ApplicationFiled: January 17, 2006Publication date: December 11, 2008Inventors: James Howard Johnston, Andrew James McFarlane, Thomas Borrmann

Patent number: 7332095Abstract: An oxidation process is described which involves subjecting a feedstock which contains oxidizable material to temperature, pressure and contact with an oxidant. Excess water and volatile oxidation products, such as carbon dioxide, formic acid and acetic acid, are removed in the vapor phase. A catalyst may be employed to increase the rate of reaction. Preferred catalysts include the transition metal ions. Advantageously, the process may be operated in a continuous manner wherein the feedstock is continuously introduced into a reactor and a vapor phase containing volatile oxidation products continuously removed. The process is particularly applicable to the treatment of consumer and industrial waste.Type: GrantFiled: June 24, 2003Date of Patent: February 19, 2008Assignee: Victoria Link LimitedInventors: James Howard Johnston, Peter Thomas Northcote, Michael James Richardson

Patent number: 7261327Abstract: Fishing hook tying apparatus includes a housing with a shaft mounted therein for rotation about the longitudinal axis. An end of the shaft protrudes from one end of the housing to form a chuck including resilient jaws and a longitudinally movable collar. The chuck is formed to grasp the shank of a fishing hook in a closed-jaws position and to release the fishing hook in an open-jaws position. A lanyard with a free end and an end attached to the shaft has a wound-position and an unwound-position. A spring is attached to the shaft and to the housing so as to produce a winding bias on the shaft when the lanyard is moved from the wound-position to the unwound-position. The winding bias tends to rotate the shaft from the unwound position of the lanyard to the wound position of the lanyard.Type: GrantFiled: February 3, 2006Date of Patent: August 28, 2007Inventor: Howard Johnston
