  • Patent number: 9563740
    Abstract: Systems and methods to simulate activity that would be recorded using an interface to nerve fibers are provided. Signals, such as motor intent signals, can be converted to neural recordings, such as neural recordings by longitudinal intrafascicular electrodes (LIFEs). Spinal cord motor pools and neural interfaces can be jointly simulated. Realistic simulated neural recordings, such as from electrodes such as LIFEs, can be provided and can be used for the evaluation of decoding algorithms. Systems and methods described herein provide a framework for developing neural interface devices.

  • Publication number: 20160287877
    Abstract: Adaptive systems and methods for automatically determining and continuously updating stimulation parameters for adjusting ventilation to accommodate a patient's specific physiology, metabolic needs, and muscle state are disclosed herein. Having a closed loop implementation, the system may comprise a controller including a neuromorphic controlled adaptive feed-forward Pattern Generator/Pattern Shaper (PG/PS) assembly, which controls respiratory muscle movement using electrical stimulation. This PG/PS assembly comprises a biomimetic design where the pattern generator includes a neural network mimicking the simplified connectivity pattern of respiratory related neurons in the brain stem to produce a rhythmic breathing pattern frequency and the pattern shaper includes a neural network mimicking the simplified connectivity pattern of neurons to produce a stimulus control signal.

  • Publication number: 20150025653
    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.

  • Publication number: 20140330404
    Abstract: Systems and methods for decoding neural and/or electromyographic signals are provided. A system can include at least one single channel decoder. Optionally, the system can include a demixer in operable communication with the single channel decoders. Each single channel decoder can include a filter to attenuate noise and sharpen spikes in the neural and/or electromyographic signals, a detection function to identify spikes, and a demodulator to get a real-time estimate of motor intent.

  • Publication number: 20140277583
    Abstract: Fitting systems and fitting methods for prostheses are provided. An instrumented prosthesis (IP), such as an instrumented prosthetic hand (IPH), can include sensors and can be connected to a neural stimulation system (NSS) or neural recording system (NRS), which includes an implanted system having electrodes. The NSS/NRS can also be connected to a software module, which can assist in calibrating the electrodes and mapping sensor values to stimulation parameters and/or mapping motor intent from recorded neural activity to control of prostheses.

  • Publication number: 20140236176
    Abstract: A method for mapping sensor signals to stimulation values and a device using the same are disclosed. The method includes the steps of receiving sensor signal from sensors, mapping the sensor signals to stimulation values, and delivering stimulation signals based on the stimulation values. The mapping may be performed using a linear, piecewise linear, or non-linear function. The method may be incorporated in an advanced prosthetic system that activates sensory neurons in a residual limb to provide an amputee with sensations related to grip force and hand opening. The method for implementing sensory feedback may also be incorporated into mechanical or robotic devices such as those used for surgery, games, and/or tele-manipulation.
