20140277581 | PROSTHETIC WITH VOICE COIL VALVE - A prosthetic includes a pair of prosthetic members movably coupled together to allow movement of the pair of prosthetic members with respect to one another. A hydraulic actuator or damper including hydraulic fluid in a hydraulic chamber is coupled to one of the pair of prosthetic members. A hydraulic piston is movably disposed in the hydraulic chamber and coupled to another of the pair of prosthetic members. A hydraulic flow channel is fluidly coupled between opposite sides of the chamber to allow hydraulic fluid to move between the opposite sides of the chamber as the hydraulic piston moves therein. A voice coil valve is coupled to the hydraulic flow channel to vary resistance to flow of hydraulic fluid through the flow channel, and thus movement of the piston in the chamber, and thus influencing a rate of movement of the pair of prosthetic members with respect to one another. | 09-18-2014 |
20140245840 | COMPACT AND ROBUST LOAD AND MOMENT SENSOR - The present invention relates to a load and moment sensor for a prosthetic device detecting load in a single direction and moment in a single plane. The load and moment sensor includes a sensing element, and a plurality of strain gauges placed in specific locations of the sensing element. The plurality of strain gauges is part of a plurality of resistor circuits such as Wheatstone bridges. While the strain gauges can be located on a single sensing element, some resistive elements of the Wheatstone bridges can be located elsewhere on the prosthetic device. The combination of the location of the strain gauges and the use of the Wheatstone bridges allows for good side load rejection which is load and moment not in the single direction or the single plane. | 09-04-2014 |
20140222167 | HYDRAULIC PROSTHETIC ANKLE - A range of motion (ROM) prosthetic foot and passive dampening ankle joint have limited dorsiflexion-plantarflexion (up and down) pivoting to accommodate different environments, and a spring to provide resilient resistance to plantarflexion (or lowering of the toe), and to bias the foot in dorsiflexion (or raising the toe). The ankle joint has a rear pivot rearward of a hydraulic link for a smooth feel. The ankle joint has an internal bumper in a hydraulic cylinder for a smooth feel. The ankle joint has an internal hydraulic compensator disposed in the cylinder and carried by the piston to equalize volume. | 08-07-2014 |
20140172120 | METHOD AND SYSTEM FOR A PROSTHETIC DEVICE WITH MULTIPLE LEVELS OF FUNCTIONALITY ENABLED THROUGH MULTIPLE CONTROL SYSTEMS - Systems and methods for a prosthetic device with multiple levels of functionality enabled through multiple control systems. The microprocessor-controlled prosthetic device stores a plurality of programmable control systems, such as a beginner control system, an intermediate control system, and an advanced control system. Based on a medical professional's assessment, the prosthetic device is programmed to operate under a programmable control system suitable to the capability level of the amputee. The microprocessor-controlled prosthetic device can be re-programmed to operate under another programmable control system as the capability level of the amputee changes. A new amputee should operate under a beginner control system, which provides high stability and low functionality. The high stability, low functionality combination provides high predictability, which helps the new amputee build confidence and trust in the prosthetic. As the amputee's capability progresses, increased functionality is provided in the intermediate and advanced control systems. | 06-19-2014 |
20140081423 | NOVEL ENHANCED METHODS FOR MIMICKING HUMAN GAIT WITH PROSTHETIC KNEE DEVICES - The present invention relates to a prosthetic device including a prosthetic joint which accurately transitions between a loose mode and a stiff mode to more accurately mimic a human gait. The prosthetic joint includes a state controller which utilizes a sensor to detect prosthetic joint movement data, and compares it with prosthetic joint movement decision values to determine when a solenoid should be energized to place the prosthetic joint in the loose mode. An optimization unit connects to the prosthetic joint in a prosthetic joint system. The optimization unit generates a plurality of data files containing prosthetic joint movement data corresponding to an amputee walking without stumbling. By iteratively analyzing the prosthetic joint movement data, the optimization unit adjusts the prosthetic joint movement decision values to ensure that the prosthetic joint does not prematurely enter a stumble recovery state. | 03-20-2014 |
