Method and apparatus for controlling an externally powered prosthesis

摘要: The present invention relates to improved controllers for externally powered prosthetic limb devices or similar extension such as orthotic a sensor probe device. controller operates highly-efficient, compact, reliable and low-maintenance tactile force feedback system translating sensed pressure from prosthesis contacting an object surface into sensory the user. comprises at least one contact-responsive transducer which translates contact portion of device contacts corresponding electrical signal. signal is received by microprocessor processed proportional output voltage producing torque motor. motor connected backdrivable planetary gearbox having rotatable shaft end lever that causes move in arc segment. opposite has attached tip member positioned contact, slightly depress, user's skin when forwardly rotated. is, thus, applied with transducer. In addition, may permit user initiate self-calibration various selected user-dependent operating parameters whenever desired adaptive filter permitting control rate movement smooth steady either slow more rapid achieved. also recognize multiple trigger patterns input generated single sites effect switching between modes operation, i.e., degrees freedom, and/or functions.
