Two-Wheeled In-Line Walker
US Patent:
2009019, Aug 6, 2009
Filed:
Feb 4, 2008
Appl. No.:
12/025137
Inventors:
Paul James Zimmerman - San Jose CA, US
International Classification:
A61H 3/04, B60B 33/00
US Classification:
135 67, 16 47
Abstract:
A supportive medical walking aid for indoor use consisting of two small caster wheels located in-line with adjustable, collapsible seat and handle bars. The invention is viewed as a long term lifestyle enhancing tool rather than a temporary rehabilitative or therapeutic device. Locomotion is provided only by a walking action of the infirmed person. The device is collapsible and light weight for easy transport and storage. Seat and handle bar placement geometry to facilitate comfortable walking, standing and forward leaning as in easy resting. Frame consisting of a front near vertical steering member with caster wheel rotatably attached; a rear member with caster wheel rotatably attached and a horizontal member vertically pivotally attached to the rear member and rotatably and releasably attached to the lower end of the front member. The adjustable, collapsible seat is attached to the rear member and the handlebar assembly is attached to the front member. A hinge connects the top of the rear member to the front member in a manner allowing rotation of the front steering member. Safety brakes are provided on both front and rear casters.

Abstract:
A non-contact system and method for measuring torsional wave propagation along a rotating shaft as well as static angular deflection due to a constant applied torque. The relative twist angle between two cross-sectional portions of the rotating shaft separated by a predetermined distance is detected over time and then the axial variation of torque along the rotating shaft is determined as a function of relative twist angle. Detection is carried out electro-optically using a pair of photodetectors and bands of reflective marks adhered on the circumferential surfaces of the two cross-sectional portions. Axial variation of torque is determined by determining variations in the phase difference between pulse trains output by the photodetectors.
