Neuromorphic controlled powered orthotic and prosthetic system
First Claim
1. A powered device for assisting a user with walking, comprising:
- a controller for controlling movement of the device;
a fixed ankle assistive device to stabilize an injured lower limb;
an actuated articulated false-foot connected to the fixed ankle assistive device to form an actuated articulated false-foot orthosis;
an actuator for driving the articulated false-foot orthosis; and
a sensor mounted on the articulated false-foot to sense movement of the articulating false-foot.

Abstract
A neuromorphic controlled powered orthotic and prosthetic system and device including a custom or universal fit fixed-ankle orthosis, to stabilize or immobilize an injured lower limb or act as an ankle prosthesis, and an actuated or powered articulated false-foot connected to the fixed-ankle orthosis or the prosthesis to form an actuated articulated false-foot orthosis. Associated with or mounted on the actuated articulated false-foot, or in or on the body, are sensors for sensing the intent of the subject to move, and the movement range of the articulating false-foot or AAFO and an environmental perturbation. An actuator is used to drive the articulated false-foot orthosis. The system and device further include a controller having an electronic circuit with a biomimetic design based on knowledge of connectivity of neurons within the spinal cord of a primitive vertebrate. The system and device include an electronic circuit made from analog very large scale integrated components and discrete electronic components capable of autonomously generating cyclic voltage output. An integral power supply serves the portable controller and AAFO.

10. A portable, powered device for assisting a user with walking, comprising:
-
a controller having an electronic circuit with a biomimetic design for controlling movement of the device and a sensor for detecting intent of the user to move, and communicating such intent to the controller to determine desired movement of the device for controlling movement of the device; a fixed ankle assistive device to stabilize an injured lower limb; an actuated articulated false-foot connected to the fixed ankle assistive device to form an actuated articulated false-foot orthosis; an actuator for driving the articulated false-foot orthosis; and a sensor mounted on the articulated false-foot to sense movement of the articulating false-foot.
