A system including a power source, one or more stimulating devices for stimulating the visual cortex of a user to present a perceived virtual image responsive to the stimulating, one or more sensing devices for sensing electrical signals in the motor and/or pre-motor cortex of the user and a processor/controller connected to the stimulating and sensing devices and programmed to sense signals from the motor and/or pre-motor cortex of the user. The sensed signals result from the user performing a movement and/or intending to perform a movement and/or imagining the performing of a movement and are used to interact with the presented virtual image. The processor/controller processes the sensed signals to obtain computed data indicative of a user's interaction with the virtual image, and performs a general computing task responsive to the computed data.

Lower-limb exoskeletons used to improve free-living mobility for individuals with neuromuscular impairment must be controlled to prescribe assistance that adapts to the diverse locomotor conditions encountered during daily life, including walking at different speeds and across varied terrain. This system employs an ankle exoskeleton control strategy that instantly and appropriately adjusts assistance to the changing biomechanical demand during variable walking. Specifically, this system utilizes a proportional joint-moment control strategy that prescribes assistance as a function of the instantaneous estimate of the ankle joint moment.

A shielding component may separate the wireless power transmitter from the wireless data receiver. An interface may be configured to communicate with a prosthesis and configured to cause the prosthesis to implement a voluntary motion based on the plurality of digital presentations of the biopotential signals.

An orthopedic device for supporting a lower limb and/or a lower back of a user includes at least one upper joint element, at least one lower joint element which can be pivoted relative to the upper joint element, and at least one actuator configured to apply a torque to the upper joint element and/or the lower joint element. Application of a torque pivots the upper joint element and the lower joint element relative to each other. The orthopedic device also includes at least one ground contact element which is connected to the lower joint element such that when the orthopedicdevice is in the mounted state, the torque applied by the at least one passive actuator is transmitted by the ground contact element to a ground on which the user is located.

The conformable convection liner is for use with a prosthetic system and configured to be donned over a residual limb of an amputee. The conformable convection liner includes a tubular body formed from an elastomeric limb-conforming material and including an outer surface and inner surface extending between a proximal end and a distal end thereof. A seal area is defined at the proximal end of the tubular body on the inner surface thereof. An outlet port is positioned at the distal end of the tubular body between the inner and outer surfaces thereof. An inner regulated environment is defined between the inner surface of the tubular body and the residual limb, the inner regulated environment extending between the proximal end of the tubular body with the seal area and the distal end of the tubular body with the outlet port. One or more internal convection guides are formed in the elastomeric limb-conforming material on the internal surface of the tubular body below the seal area and configured to promote the flow of fluid within the inner regulated environment towards the outlet port at the distal end of the tubular body.
