Ambulating Ankle & Knee Joints With Bidirectional Dampening And Assistance Using Elastomeric Restraint
US Patent:
2007027, Nov 22, 2007
Filed:
Nov 15, 2006
Appl. No.:
11/600362
Inventors:
Mark DeHarde - Pottstown PA, US

Assignee:
Ultraflex Systems, Inc. - Pottstown PA
International Classification:
A61F 2/74, A61F 2/64
US Classification:
623027000, 623042000, 623047000
Abstract:
A hinge or joint assembly includes a first member movably connected to a second member to allow angular displacement of the first member relative to the second member in each of extension and flexion (clockwise and counterclockwise) directions, where one elastomeric spring restrains angular displacement in a flexion position, and another elastomeric spring restrains angular displacement in an extension position. In each direction, the angular movement is dampened through compression of the respective elastomeric spring. After dampening the movement in either direction, returning movement is assisted through decompression of the respective elastomeric spring. Alternatively, one or more elastomeric springs are arranged to both dampen through compression and assist through decompression angular movement in each of the flexion and extension directions. The elastomeric spring can provide a pre-determined force deflection curve in compression and an independent rate of return hysteresis in decompression. The elastomeric springs could be urethane.

International Classification:
H03K 17/78
US Classification:
2502141, 250214 SW
Abstract:
An optical proximity switch includes an optical transmitter for emitting a light signal, a transmitting lens with total internal reflection using the light signal to form and transmit a light beam , a receiver, an imaging receiving lens for receiving and transmitting to the receiver the light signal, and an electronic circuit for evaluating the light signal received by the receiver.
