20140249652 | PROSTHETICS USING CURVED DAMPENING CYLINDERS - Prosthetic joint and limb components utilize a single, curved dampening cylinder to reduce component count and wear. A prosthetic foot/ankle requires only three major components; namely, a housing adapted for coupling to a foot blade, an ankle component adapted for coupling to a pylon, and a piston that moves within a curved cylinder in the housing during ambulation. The ankle component is pivotally attached to the housing at the center of curvature of the cylinder. The piston defines front and rear, variable volume chambers in the cylinder. The chambers are in fluid communication with one another via a port, such that fluid is exchanged between the chambers through one-way check valves as the ankle pivots between plantarflexion and dorsiflexion. Fluid flow is independently adjustable to establish and maintain desired levels of dampening during plantarflexion and dorsiflexion, including different levels of dampening. | 09-04-2014 |
20140076066 | MULTICAPACITOR FORCE/MOMENT SENSOR ARRAYS - A multicapacitor sensor system facilitates the measurement of applied shear and moment forces. In one disclosed configuration, moments may be detectable in x, y and z directions, resulting in a full, 3-axis load cell with 6 degrees of freedom. The system may further include electrical circuitry to generate electrical drive pulses, sense amplify and buffer the voltages induced on the sense plates, and compute applied forces. An array of multicapacitor sensors that can be addressed individually without cross-talk and globally produce a map of forces and moments applied to the whole array. A MEMS implementation enables in vivo application. | 03-20-2014 |
