20120316475 | ACTUATOR SYSTEM WITH A MOTOR ASSEMBLY AND LATCH FOR EXTENDING AND FLEXING A JOINT - An actuator system for assisting extension of a biological joint is provided with a motor assembly, a rotary-to-linear mechanism, and an extension stop. The rotary-to-linear mechanism includes a screw that accepts rotational output of the motor assembly, and a nut that cooperates with the screw to convert rotational movement of the screw to linear movement of the nut. The extension stop is driven by linear movement of the nut in an extension direction to cause extension of the biological joint. The motor assembly, the rotary-to-linear mechanism and the extension stop cooperate to allow unpowered flexion of the joint. The system is configured without a flexion stop, and is configured such that the nut cannot drive the joint in a flexion direction. Methods of use are also disclosed. | 12-13-2012 |
20090204038 | MULTI-FIT ORTHOTIC AND MOBILITY ASSISTANCE APPARATUS - A multi-fit orthotic structure including an attachment system for coupling the orthotic structure to a wide variety of subjects without requiring a custom fit. In one embodiment, active mobility assistance is provided via an orthotic system capable of integrating a linear actuator and linkage system to deliver torque to the lower leg of a subject to facilitate flexion and/or extension motion of the subject's leg. The orthotic structure is attached to the subject using a textile suspension system which does not require the orthotic structure to interface directly in the knee region or at the lateral areas of the thigh and calf of the subject, thus providing an ideal fit for the widest possible range of subjects with the minimum number of required sizes. | 08-13-2009 |
20080203841 | HIGH-TORQUE MOTOR - A motor that delivers high force linear motion or high torque rotary motion to a moving element. The motor may include a driving brake, a driver, a holding brake and a flexible moving element. Operation of the motor may involve activating the holding brake, activating the driver to flex the moving element, activating the holding brake to maintain the position of a portion of the moving element, releasing the driving brake, and restoring the moving element to an unflexed position. The elements are arranged to provide linear motion, belt-driven rotary motion, or directly-coupled rotary motion using brakes and drivers arranged in linear or circular fashion. Drivers may be linear or rotary actuators or motors based on electrostatic, piezoelectric, magnetic, or electrostrictive properties. The brakes may be applied through electrostatic forces, magnetic forces, or mechanical gears engaged with a linear or rotary driving mechanism. | 08-28-2008 |
