Abstract: A portable system for dynamometry, exercise, and rehabilitation comprises a base, a detachable servomotor assembly, an embedded control system, and a physical human-machine interface for securing a human limb into a stabilized position for use in a repeatable and ambidextrous manner. In another embodiment, the portable system includes a power source and a user interface subsystem for selecting operative modes and input parameters and for real-time processing, display, and storage of the values collected by the system during operation. In another embodiment, a method for determining strength of an isolated muscle group of a human joint is disclosed. The method includes the steps of mounting and securing a detachable servomotor assembly of a portable dynamometer upon a surface and securing the human joint to be tested into a stable position with an adjustable, ambidextrous distal limb attachment assembly for use of the portable dynamometer in a readily repeatable manner.

Abstract: A system and method is provided for a wearable robotic upper body garment. In an embodiment, an upper body garment or apparatus comprises a shoulder saddle, one or more actuators, one or more flexible tendons, back torso section, front, torso section, torso wrap, and upper arm cuff. The shoulder saddle may be comprised of a yoke and one or more elevated shoulder sections. The one or more elevated should sections may be comprised of a first elevated shoulder section. In an embodiment, the back torso and front torso sections may be structurally connected to the yoke. In an embodiment, the one or more actuators may be structurally connected to either said back torso section or front torso section. In an embodiment, the one or more flexible tendons may be operationally connected to a predetermined one or more actuators and an upper arm cuff.

Abstract: In an embodiment, a relative deflection detector may include at least two structural arcs, and a predetermined number of means for measuring position capable of determining the relative deflection in a first component. The at least two structural arcs may be for example, comprised of a first and second structural arc whereby the first and second structural arcs are attached to the first component at respective first and second predetermined locations and whereby each arc is comprised of a respective sequence of indicators, such as, for example, codes inscribed on the outer circumference of each arc. The first and second structural arcs may be positioned in concentric and coplanar relationship with each other.

Abstract: A tendon actuator unit comprises a housing; a pulley disposed within the housing, the pulley comprising a screw-like groove about a predetermined portion of an outer surface of the pulley configured to accept a predetermined length of a cable; a motor disposed in or proximate to the housing and operatively in communication with the pulley; one or more online cable sensors; one or more sensor rollers; and one or more conduit force sensors.
