Patent number: 8264458Abstract: The present invention provides variable compliance joysticks with mechanical and software customization, and with an integrated control capability, and a method of systematically determining the best mechanical settings and compensatory algorithms to embed in the joysticks to offer an individual with substantial upper extremity motor impairments a personal fit and maximum function. The joysticks may include components for varying the compliance and dampening of the joystick shaft. The method may include providing the user access to operate the joysticks, operatively connecting the joysticks to a driving simulator, displaying an icon on the driving simulator, controlling movement of the icon by the joysticks, evaluating performance of the user based upon the user's ability to control movement of the icon, and modifying hardware settings and software algorithms for the joysticks based upon the evaluation.Type: GrantFiled: January 13, 2009Date of Patent: September 11, 2012Assignees: Dept. of Veterans Affairs, The University of Pittsburgh of the Commonwealth System of Higher EducationInventors: Rory A.

Publication number: 20110245747Abstract: A splint for treatment of a joint including a generally longitudinal body including first and second portions forming inner and outer splint layers, with the second portion being rollable onto the first portion to form the splint. The outer splint layer may include a longitudinal cavity for insertion of a stay, and/or may include a fluted section for permitting insertion of a stay between the inner and outer splint layers. The longitudinal body may be linear or curved. The first and second portions may include areas having different thicknesses for adding rigidity to the splint structure at a predetermined location. The splint may include a cutout for exposing a predetermined portion of a user's finger. The splint may be made of a flexible material such as rubber, silicone and/or urethane. The splint may include a reduced friction surface layer for minimizing sticking of the splint during donning.Type: ApplicationFiled: February 22, 2011Publication date: October 6, 2011Inventors: Ronit Wollstein, Thomas Ogden, Jonathan Pearlman, Rory A.

Publication number: 20110162166Abstract: Caster alignment mechanism having a first component operably connected to a leg of a mobile device and a second component operably connected to a caster of the mobile device. The first and second components are positioned in parallel orientation to each other wherein alignment. of the caster with the leg of the mobile device is achieved by the attractive characteristics of the first component with an upper magnet to the second component with a lower magnet. One embodiment of the caster alignment mechanism includes a fixed gap between the upper magnet and the lower magnet for an always engaged or “on” mode. The fixed gap can be adjusted to vary magnetic field strength depending on user specifications for ease of turning. Another embodiment of the caster alignment mechanism includes a switching mechanism to change modes between engaged or “on” mode and disengaged or “off” mode.Type: ApplicationFiled: November 30, 2010Publication date: July 7, 2011Inventors: Rory A. Cooper, Andrew M. Kwarciak, Mark A. McCartney, Jonathan Lee Pearlman

Publication number: 20110162905Abstract: Steering mechanism that increases adjustability. The steering mechanism can have different gear ratios between the input rotation from the user and the output rotation on the drive wheel. The steering device will allow users to employ a pushing or pulling motion for steering instead of pushing to turn in one direction and pulling to turn in the opposite direction. Users with weaker torso strength may not be able to maintain their balance when they pull on a steering tiller. Allowing users to choose the type of motion for steering, and to supplement one motion with the other, creating flexibility and support for users with various abilities. Lastly, the steering system should not impede a user transferring into and out of the personal vehicle.Type: ApplicationFiled: February 8, 2011Publication date: July 7, 2011Inventors: Jonathan L. Pearlman, Rory Cooper

Patent number: 7497456Abstract: A pushrim with increased surface area and an insert between the wheel and the pushrim. In the preferred embodiment, the cross-section of the pushrim is an elongated circle and the insert is a concave trough made of an elastic material which compressibly fits between the wheel and the rim for convenient installation. Improved pushing is provided by texturing the surface of the insert to provide increased friction. Improved braking is provided by providing a smoother and wider surface on the pushrim.Type: GrantFiled: October 29, 2003Date of Patent: March 3, 2009Inventors: Christopher J. Willems, Mark Baldwin, Michael L. Boninger, Rory A. Cooper

Publication number: 20080209673Abstract: An improved caster comprising a caster mount attachable to a frame of a mobile device, caster stem attached to the caster mount and operable to attach to a caster fork and wheel assembly, and a biasing means operable to restrict the rotation of the caster stem and thereby to prevent caster drift and flutter and to promote tracking of the mobile device. The biasing means can be in manner whereby the caster stem has at least one vertical notch defined therein and the biasing means comprises a spring plunger located in the caster mount. The spring plunger has an internal spring and a movable ball member attached to the spring and which faces the caster stem whereby the ball is biased against the caster stem and situated within the caster stem notch when the caster stem is in a desired rotational position. The biasing means can also employ magnets located in the caster stem and caster mount which align at opposite attracting poles when the caster is in a desired position.Type: ApplicationFiled: February 22, 2008Publication date: September 4, 2008Inventors: Rory A. Cooper, Andrew M. Kwarciak, Mark A. McCartney
