  • Publication number: 20220031479
    Abstract: Proprioceptive feedback is provided in a residual limb of a person that includes forming a linkage between a pair of agonist and antagonist muscles, forming a sliding surface over which the agonist and antagonist muscles slide. The sliding surface can include a synovial sleeve, a bridge formed between the distal ends of bones, or a fixture that is osseointegrated into the bone. The invention also includes a system for transdermal electrical communication in a person that includes a percutaneous access device, a sensory device that communicates signals between a muscle and the percutaneous device, and a stimulation device in communication with the percutaneous access device. In another embodiment, a closed-loop functional stimulation system restores lost functionality to a person that suffers from impairment of a neurological control system or at least partial loss of a limb.

  • Publication number: 20220031552
    Abstract: Systems and methods for communicating between multiple lower limb exoskeletons are provided. A first exoskeleton boot can receive, responsive to transmitting a first packet, a second packet from a second exoskeleton boot through a wireless connection between the first exoskeleton boot and the second exoskeleton boot. The first exoskeleton boot can determine a latency for communication between the first exoskeleton boot and the second exoskeleton boot based on a time difference between transmission of the first packet and receipt of the second packet and update, responsive to the comparison, a model indicating data weighted based on the latency for controlling the first exoskeleton boot and the second exoskeleton boot. The first exoskeleton boot can generate, using data from the model, a command to cause an electric motor of the first exoskeleton boot to generate torque to aid a limb of a user in performing a movement.

  • Publication number: 20210378903
    Abstract: Systems and methods for determining a level of collaboration between a user and an exoskeleton boot are provided. A device, using an exoskeleton boot, can provide a level of force to a limb of a user to aide movement of the limb. The device can measure one or more parameters of the exoskeleton boot during the movement of the limb using the exoskeleton boot. The device can determine one or more biometrics of the user during the movement of the limb using the exoskeleton boot. The device can determine, based on the one or more biometrics and the one or more parameters of the device, a metric indicative of a collaboration between the user and the exoskeleton boot during the movement.

  • Publication number: 20210369536
    Abstract: A system to augment motion via a battery-powered active exoskeleton boot is provided. The system can include a controller and an electric motor that generates torque about an axis of rotation of an ankle joint of the user. The controller can receive sensor data associated with activity of the exoskeleton boot during a first time interval. The controller can determine, based on the sensor data input into a model trained via a machine learning technique associated with one or more users performing one or more physical activities, one or more commands for a second time interval. The controller can transmit the one or more commands generated based on the model to the electric motor to cause the electric motor to generate torque about the axis of rotation of the ankle joint of the user in the second time interval.

  • Patent number: 11173093
    Abstract: An apparatus for a battery-powered active exoskeleton boot includes a shin pad and one or more housings. The one or more housings enclose electronic circuitry and an electric motor. The apparatus includes a battery holder coupled to the shin pad and located below the knee of the user and above the one or more housings enclosing the electronic circuitry. The apparatus includes a battery module removably affixed to the battery holder and comprising a first power connector that electrically couples to a second power connector located in the battery holder while attached to the battery holder to provide electric power to the electronic circuitry and the electric motor. The apparatus includes an output shaft coupled to the electric motor. The electronic circuitry controls delivery of power from the battery module to the electric motor to generate torque about the axis of rotation of the ankle joint of the user.

  • Patent number: 11148279
    Abstract: Systems and methods for providing a customized configuration for a controller of an exoskeleton device. A device can receive, via a user interface, feedback from a user indicative of a performance of the user during a movement event. The device can determine characteristics of the user for performing the movement event using a first exoskeleton boot and a second exoskeleton boot and identify properties of a route for the movement event. The device can determine using the characteristics of the user, the feedback and the properties of the route, control parameters for the first exoskeleton boot and the second exoskeleton boot to execute the movement event. The device can apply the control parameters to the first exoskeleton boot and the second exoskeleton boot for the user to operate the first exoskeleton boot and the second exoskeleton boot during the movement event.

  • Patent number: 10765581
    Abstract: A spool assembly and method of use is disclosed having generally a first and a second mating portions which can mate along a longitudinal axis of the spool to retain a belt therein. The mating surfaces of the first and second mating portions can take a variety of geometries or splines which can efficiently retain the belt while maintaining a suitable transmission ratio. In an exemplary embodiment, the spool exit curve for the retained belt can be radially inward of a majority of the spool to reduce the overall diameter of the spool. In some exemplary embodiments, the spool can be mounted within a motor and rotated thereby to spool and unspool the belt.
