    • Introducing Asymmetry to Wheelchair Design 

      Kong, Linghua (Georgia Institute of Technology, 2005)
      This paper reports the use of asymmetry in designing the chassis of a power wheelchair. The innovative design uses and tests two kinds of power wheels and a new suspension structure. This design carefully considers features ...
    • Inventor-Driven Product Development 

      Sprigle, Stephen; Maurer, Chris; Kong, Linghua (Georgia Institute of Technology, 2010)
      Inventors of assistive technology often lack resources to support product development and this may hinder their ability to develop useful and commercially viable devices. The purpose of this on‐going project is to support ...
    • Investigation of the Lifespan for Wheelchair Cushions used on a Daily Basis 

      Rivard, David M.; Sprigle, Stephen; Linden, Maureen (Georgia Institute of Technology, 2008)
      Wheelchair cushions function to mediate seating pressures and provide postural stability. For the majority of cushions used on average 12 hours daily, the cover and interior components degrade at varying rates while ...
    • Kangan Roo Project 

      Johanson, Colin; Jowers, Jonathan (Georgia Institute of Technology, 2007)
      The ‘Kangan Roo’ is an innovative electric wheelchair design that can automatically contract and extend its wheelbase while in use. By lengthening the wheelbase it becomes a sturdy outdoor electric wheelchair that can ride ...
    • Kinematics of Lateral Transfers: A Pilot Study 

      Sonenblum, Sharon Eve; Sprigle, Stephen; VanHeil, Leslie; Maurer, Chris (Georgia Institute of Technology, 2005)
      People with spinal cord injuries (SCI) must transfer many times daily. Despite the importance of proper transfers, researchers have not completely described the kinematics of lateral transfers. In this study, 19 male adults ...
    • Kinematics of Lateral Transfers: A Pilot Study 

      Sonenblum, Sharon Eve; Sprigle, Stephen; VanHiel, Leslie; Maurer, Chris; Whittaker, Eric (Georgia Institute of Technology, 2005)
      People with spinal cord injuries (SCI) must transfer many times daily. Despite the importance of proper transfers, researchers have not completely described the kinematics of lateral transfers. Nyland et al identified ...
    • Load Redistribution in Standing, Tilt-in-Space, and Reclining Wheelchairs
