A wireless power transfer system including a driver coil array, a hexagonally-packed transmitter mat, a receiver coil, and a load coil for powering a medical implant. The magnetically coupled resonance between two isolated parts is established by an array of primary coils and a single small secondary coil to create a transcutaneous power link for implanted devices as moving targets. The primary isolated part includes a driver coil array magnetically coupled to a mat of hexagonally packed primary coils. Power is injected by the driver coils into the transmitter coils in the transmitter mat to maintain resonance in the presence of losses and power drawn by the receiver coil from the magnetic field. The implanted secondary isolated part includes a receiver coil magnetically coupled to a load coil. A rectification/filter system is connected to the load coil supplying DC power to the electronic circuits of the implant.

A repetitive motion therapy apparatus has a frame structure. An orthotic is adapted for securing to a part of a body. A pneumatic muscle is coupled between the frame structure and the orthotic for moving the orthotic. A control mechanism controls the pneumatic muscle. The pneumatic muscle contracts to impart movement to the orthotic. A winding spool and retractable cord is attached to the pneumatic muscle. The pneumatic muscle is operated by an electric mechanism, hydraulic mechanism, or spring mechanism to impart movement to the orthotic. The control mechanism has a variable airflow controller to control the movement of the orthotic. A feedback sensor is disposed on the body for providing data to the control mechanism. A treadmill imparts motion to the part of the body.

Apparatus and method for repetitive motion therapy

A method for restoring functional ambulation in subjects with incomplete spinal cord injuries which includes partial weight bearing therapy followed by epidural spinal cord stimulation (ESCS) to facilitate partial weight bearing therapy and over-ground walking. Electrical epidural stimulation (EES) is generated by an implanted device during partial weight bearing therapy on a treadmill. The subject is then transitioned to full weight bearing gait training on a treadmill with EES to over-ground gait training with EES and a walker, and finally to full weight bearing independent stepping over-ground with EES with or without an assistive device.

An ultrasonic path guidance system and method for the visually impaired uses an array of ultrasound transmitters that are directional and aimed at distinct locations forward of the user. The transmitters are positioned on the torso of the individual user and one or more receivers detect echoes from obstacles upon which the transmitted ultrasound sound impinges. Audible tone is generated each time an echo is received. The tone's frequency is dependent on which transmitter transmitted the original ultrasound pulse that resulted in the detected echo. This gives an easy to understand indication of the location of detected obstacles. The elapsed time from emission of an ultrasound pulse to reception of its echo is used to arrive at the distance to the obstacle.
