  • Patent number: 11497429
    Abstract: The subject of the invention is a method for calibrating a direct neural interface. The calibration is performed by considering a so-called input calibration tensor, formed on the basis of measured electrophysiological signals and so-called output calibration tensor, formed on the basis of measured output signals. The method comprises the application of a least squares multivariate regression implemented by considering a covariance tensor and a cross-covariance tensor which are established on the basis of input and output calibration tensors corresponding to a current calibration period. The method takes into account covariance and cross-covariance tensors established during an earlier calibration period prior to the current calibration period, these tensors being weighted by a forget factor.

  • Patent number: 10610099
    Abstract: Systems and methods for simultaneous position and impedance control for myoelectric interfaces are disclosed herein. Properties such as control refinement, retention, generalization, and transfer allow users to learn simultaneous and proportional motion simply by interacting with a myoelectric interface, regardless of its initial intuitiveness. The presently disclosed technology expands on these motor learning approaches by implementing a multidirectional impedance controller in this framework. Using sEMG inputs from upper limb muscles, users simultaneously control both the stiffness and set-point of 3-DOFs. Users stabilize control in the presence of external forces in an analogous way to natural limb movements. Despite having no haptic feedback, subjects learn to tune the stiffness of the object being controlled to stabilize movement along desired paths.

A finite state machine utilizes the current position of the prosthetic hand and the identified input class to identify the coordinates of a lookup table to determine the next state or position of the prosthetic device. As a result, the biomimetic controller is able to simultaneously control two or more degrees of freedom (DOFs) or functions of the prosthetic hand using only two EGM input signals.

The method also includes, based on real-time sensor information, transitioning the device between different states in the finite state model when pre-defined criteria for transitioning among the different states are met. In the method, the finite state model for stair ascent includes lifting and swing phases, where the lifting phase includes a powered knee extension and a powered ankle push-off. The finite state model for stair descent includes yielding and swing states, where the swing states include providing a powered plantarflexion of the powered ankle joint and the yielding states include providing a resistive and passive plantarflexion of the powered ankle joint.

  • Patent number: 10369022
    Abstract: A control system for control of a prosthetic device having a plurality of actuators receives an orientation signal indicative of a desired movement. The control system evaluates whether the prosthetic device may move as desired with a current angle of rotation and commands at least one actuator to move the prosthetic device as desired by maintaining the current angle of rotation or by adjusting the angle of rotation if the prosthetic device cannot move as desired with the current angle. The control system may alternate between commanding a first subset of actuators and a second subset of actuators each time the orientation signal is indicative of a neutral position. The control system may include a position sensor and a compliance sensor and may command at least one actuator based on a combination of positional control using the position sensor and force control using the compliance sensor.

    Abstract: Electrical feedback is provided to a user who cannot receive full sensation from a body part due to amputation, neuropathy or other condition. A sensor array includes an array of capacitive force-sensing elements operative to sense axial and shear forces applied to that element. Temperature may also be sensed at each force-sensor location. An electrode matrix, adapted for external placement in an area on a user of the sensor array, includes an array of electrodes in physical correspondence to the array of capacitive sensing elements of the sensor array. An electronic controller is configured to receive electrical signals representative of the axial and shear forces applied to the sensor array and drive the electrode matrix with electrical stimulation signals corresponding to the electrical signals received from the sensor array, thereby enabling the user to experience force and/or temperature sensations experienced by the body part through the electrode matrix.

  • Patent number: 10166394
    Abstract: Described is a system for automatically tuning the sensor feedback of a prosthetic device. The system comprises an electrode or plurality of electrodes in contact with a peripheral nerve of a user wearing a prosthetic device for administering the sensory feedback and an additional stimulus that evokes a muscle response in the user. A sensor is used to measure the muscle response. One or more processors generate a current stimulation pattern that encodes a posture of the prosthetic device. The current stimulation pattern is used in a spinal cord simulation to produce predicted muscle activations. Using the muscle response and the predicted muscle activations, an adjusted stimulation pattern is determined.
