    Abstract: A method for assessing the status of a piezoelectric sensor of interest 26, comprises the steps of 1) establishing a complex impedance profile expected to be exhibited by an acceptable sensor subjected to a test signal, 2) exciting the sensor of interest with a periodic excitation signal correlatable to the test signal, 3) analyzing the complex impedance of the excited sensor relative to the complex impedance profile, and 4) reaching a conclusion about the status of the sensor of interest based on the analysis. A system for carrying out an assessment of the status of a piezoelectric sensor of interest includes an analog signal source 32, a communication path 34 for placing the signal source in communication with the sensor of interest 26, means for digitizing a complex impedance exhibited by the excited sensor, and a processor 42 having access to a complex impedance profile representing an expected complex impedance of the excited sensor and also having access to an algorithm for analyzing digitized complex impedance relative to the complex impedance profile and for generating a status signal 48 responsive to the analysis.

    Abstract: Techniques are provided for controlling a human-exoskeleton system including an ankle-foot orthosis by receiving system parameters for the human-exoskeleton system, receiving generalized coordinates such as an orientation of the foot, and determining a joint torque for controlling the ankle-foot orthosis to compensate for one or more components of forces acting on the foot. Forces selected for compensation include gravitational forces as well as external forces such as ground reaction forces. Techniques are provided for determining an ankle joint torque for partial or complete compensation of forces acting on the foot about an axis of rotation. The provided techniques mitigate the amount of interference between voluntary control and assist control, thereby allowing humans to quickly humans adapt to an exoskeleton system.

    Abstract: According to a first embodiment of our invention, a monitoring device is placed above, within, or on the bottom of a cast, boot, shoe, or other lower extremity immobilization or protective device, and has one or more single or cluster of pressure sensitive chambers designed to burst at a predetermined force or weight. The pressure sensitive chambers may be filled with air, liquid, semi-liquid, or particulate material. Once properly positioned, the device serves to detect and alert one or more individuals to the fact that weight-bearing has occurred and/or that a certain amount of force has been transmitted across the bottom or other portion of the cast, boot, shoe, mat, sock, insole, or lower extremity immobilization or protective device in a setting where such pressure could be deleterious or harmful (including situations where patients are recovering from a bony fracture, tendon injury, and recent lower extremity surgery).
