Abstract: Systems and methods for providing hemodynamic support to a patient with an intravascular blood pump are disclosed. In some implementations, the blood pump includes a motor and an improved motor cable for delivering electrical power to the motor. The motor includes a stator with one or more coils. The motor cable includes one or more electrical conduits. The motor cable also includes a tail portion and a head portion. In some implementations, the head portion may have an O-shape or a C-shape. The motor cable may reduce the complexity of assembling the blood pump. For example, the motor cable may reduce the risk of shorting the one or more coils and/or the one or more electrical conduits.

Abstract: A blood pump with a stator and rotor wherein the rotor is assembled by bonding the stator components with epoxy. The bonding surfaces of the rotor components are primed with a silane-based primer to improve adhesion between the primer and the rotor components by rendering such surfaces hydrophobic. A bonding surface of one of the stator yoke or the stator sleeve, or both, is treated with a primer that improves wettability of the bonding surface and improves bonding of the epoxy to the binding surface. The device has a bonding surface adhered to epoxy in which a primer was applied on such bonding surface prior to introducing epoxy onto the bonding surface. In addition to improved bond strength, hydrophobic surface would control moister ingress.

Abstract: Systems, methods and components of a joint actuating gait training system are provided. The gait training system includes a base support frame and an upper flexion actuation assembly movably coupled to the base support frame and a lower flexion actuation assembly movably coupled to the base support frame.

Abstract: A balanced planetary gearbox including an assembly having an input stage and an output stage. The assembly includes two grounds, each with ground rollers and ground rings. The two grounds are fixedly attached to one another. The assembly includes a sun gear and planet sub-assemblies between the two grounds. The planet sub-assemblies include at least one input planet gear and one output planet gear. The sun gear and the input planet gears include rollers. An abutment of rollers in the gearbox keeps the sun gear and the planet gears in alignment. The output gear meshes with an output ring disposed in between the two ground rings, such that a combination of the at least one input planet gears from each of the plurality of planet sub-assemblies provides a structural symmetry to the planetary gearbox.

Abstract: In some embodiments, systems and methods are described for a gear contact system configured to support radial, thrust, and moment loads, the system comprising a first gear comprising a first roller having a first roller bearing surface, the first roller bearing surface having a convex curvature defined by a first radius of curvature; and a second gear comprising a second roller having a second roller bearing surface, the second roller bearing surface having a concave curvature defined by a second radius of curvature.

Abstract: The present application is directed towards methods and systems for an interactive cyclist monitoring and crash prevention system. The methods include creating, by a safety sensor, a virtual smart lane around a bike operated by a rider during a cycling session. The virtual smart lane may indicates a safe zone around the bike. The method further includes the safety sensor detecting an object approaching the virtual smart lane during the cycling session and generating an alert to the rider of the bike to notify the rider of the approaching object.

Abstract: The present application is directed towards methods and systems for an add-on smart pedal and computer based application to provide cyclist monitoring and recommendations. The methods include displaying, by a virtual coach, characteristics of a bike in a first virtual cycling session, the characteristics measured by a pedal sensor during a cycling session. The virtual coach may assess a performance of a rider during the cycling session and generate recommendations the first virtual cycling session based on the performance of the rider. Further, the virtual coach may create a second virtual cycling session based on the rider performance and the recommendations.

Abstract: The Navigator is multiple degree of freedom neuro rehabilitation system. The Navigator simultaneously exercises both pronation and supination of the wrist (rotation) and flexion and extension of the fingers (grasp and release) for rehabilitation and monitoring of patients with motor control deficits due to a neurological ailment, such as stroke. In addition, the Navigator provides a visual, interactive environment for performing therapeutic exercises. The interactive environment provides motivation to the patient and can provide real-time feedback to the patient about the quality of the movements being performed.
