  • Linear actuator
    Patent number: 9017419
    Abstract: Linear actuators that allow for improved self-locking properties without sacrificing axial response are provided. A linear actuator can have two screws extending from opposite ends of the actuator. The screws are joined by and threadably coupled to an elongate rotating nut. An elongate magnet is disposed around and coupled to the nut, and a stator including coils surrounds the magnet and nut. The magnet and nut are not axially fixed with respect to the stator. Rotation of the nut causes axial displacement of both screws, causing the screws to move closer together or farther apart. A pitch of the screw threads can be selected to enhance self-locking properties.

  • Control systems and methods for prosthetic or orthotic devices
    Patent number: 9017418
    Abstract: Geomagnetic methods and systems are used for monitoring the directionality of a prosthetic or orthotic device. Certain methods may include measuring multiple data points over a particular time interval to identify orientation information with respect to a prosthetic or orthotic device and/or used in the real-time control of the prosthetic or orthotic device. In certain examples, multiple points may be further compared with stored orientation data associated with predefined unsafe gait patterns. Control instructions and/or alerts based on the geomagnetic measurements can then be generated for the prosthetic or orthotic device, such as if the orientation data information matches one of the predefined unsafe gait patterns.

  • Prosthetic foot with resilient heel
    Patent number: 8961618
    Abstract: A prosthetic foot can include a resilient heel member that can be removably coupled to the bottom of a plate-like foot member of the prosthetic foot. The heel member can be made of a resilient material, such as foam. The heel member can have a shape that corresponds to a foot cover and allows the prosthetic foot to fit within a foot cover. A lip may be provided to engage with a corresponding portion of the foot cover to secure the heel member within the foot cover. A rib can be located on the bottom of the heel member to create horizontal or vertical displacement of the foot at heel strike. A recess can be created in the heel member to removably receive an insert, which can alter the stiffness of the heel member.

    Patent number: 8915968
    Abstract: Prosthetic and/or orthotic devices (PODS), control systems for PODS and methods for controlling PODS are provided. As part of the control system, an inference layer collects data regarding a vertical and horizontal displacement of the POD, as well as an angle of the POD with respect to gravity during a gait cycle of a user of the POD.
