An electromagnetic brake assembly includes a solenoid coil; a fixed ferrous brake stator; a ferrous armature having a braking face, wherein the armature is moveable in a translation direction relative to the brake stator between a disengaged position and an engaged position; and a rotating member including a mating surface and that rotates relative to the armature when the armature is in the disengaged position. When the solenoid coil is energized, the armature translationally moves from the disengaged position to the engaged position, and in the engaged position the braking face of the armature interacts with the mating surface of the rotating member to apply a braking force to the rotating member. The braking face and the mating surface may form a conical interface, and the conical interface further may include a friction O-ring positioned within a slot that permits the O-ring to roll along the braking interface when the armature moves between the disengaged position and the engaged position.

The present invention is directed to an autonomous exoskeleton device that includes one or more actuators, one or more controllers, one or more sensors with one or more unidirectional transmissions. The present invention provides a mechanical joint in parallel with a biological joint. The exoskeleton device preferably includes and electric motor and winch, chain, belt, cam transmission or other mechanism for providing unidirectional force to assist rotation about the biologic joint. Moreover, a controller, a motor angle sensor, joint angle sensor and/or force sensor may be used for additional control and monitoring of the device. The motor may be any type of motor, but is preferably brushless in configuration where its diameter is larger than its length to provide a compact and lightweight exoskeleton device.

Device (100) for assisting with mobilizing a joint (3) comprising a first and a second guiding element, the first flexible guiding element (102) being positioned on one of the segments (4), having a first pair of cable passages arranged on the side of the rear face (52) and on the side of the front face (54), the second flexible guiding element (104) being positioned on the other of the segments (5), having a first pair of cable passages, arranged on the side of the rear face (52) and on the side of the front face (54), the second guiding element further comprising a pair of anchoring points arranged on the side of the front face (52) and on the side of the rear face (54), a flexible support part on which a pair of actuators (M11, M12) associated with a pair of winders are arranged, to cause the associated winder to turn in the winding direction and the unwinding direction, and a pair of cables (C11, C12) extending from the winders, up to the anchoring points of the second guiding element, passing through the cable passages of the first pair of cable passages of the first and second guiding elements.

The present disclosure discloses an exoskeleton for rehabilitation, comprising: a healthy-side exoskeleton, an affected-side exoskeleton, a first sensor, a control unit, and a driving device, wherein the first sensor is configured to detect a pressure received by the shoe sole and generate a first electrical signal, the control unit is configured to judge, according to the first electrical signal, whether to generate the first control signal, and the driving device is configured to drive the affected-side exoskeleton according to the first control signal. When a shoe sole is not landed steadily, the affected-side exoskeleton does not drive the affected side to step out, thereby avoiding the problem that the affected side takes a step when the healthy side does not stand firm. Therefore, the present exoskeleton for rehabilitation has the advantages of better controlling for limb coordination and having higher using safety.

A maintenance system includes: a walking training apparatus including a walking assistance apparatus attached to a leg of a trainee, and to assist the trainee in walking, and first transmission means for transmitting information in which information about the number of times of walking or a time of walking performed in the walking assistance apparatus is associated with a component of the walking assistance apparatus; and a server including determination means for comparing the information about the number of times of the walking or the time of the walking transmitted from the first transmission means with a preset evaluation value for durability of the walking assistance apparatus, and determining a timing for performing maintenance for the walking assistance apparatus, and second transmission means for transmitting maintenance information including the timing of the maintenance determined by the determination means and information about the associated component of the walking assistance apparatus.

A device and a method for reversibly connecting a rehabilitation mechanism to a bed, such as a hospital bed that can be brought to a vertical position. The device has a connection element arranged on the rehabilitation mechanism; a receiving unit, which can be arranged at the side of and/or at the foot end of the bed; the receiving unit corresponds in design to the connection element; and a transport device for transporting the rehabilitation mechanism toward and away from the bed. The transport device and/or the bed is height-adjustable. A method for operating a rehabilitation mechanism connected to a bed by way of the novel device. Easy, fast, reversible connection of a rehabilitation mechanism to a conventional hospital bed is enabled, in particular to a hospital bed that can be brought to a vertical position. Existing beds can be quickly and economically retrofitted with a robot system for kinesiotherapy.

A lower limb training rehabilitation apparatus, comprising a weight reducing device, a pelvis supporting device, an exoskeleton device, a control system for controlling mechanical movements of the rehabilitation apparatus, and a treadmill used for walking of a patient. The rehabilitation apparatus hoists the upper body of the patient by means of the weight reducing device, then fixes the crotch of the patient to the pelvis supporting device, and fixes two legs of the patient to two mechanical legs of the exoskeleton device. A power source drives the pelvis supporting device to move up and down, so that the patient can move in the vertical direction; in addition, a sliding base of the pelvis supporting device can assist the patient in moving left and right, swinging left and right, and twisting. The mechanical legs and the treadmill together implement arbitrary movements in six degrees of freedom of the patient.

Provided is a travel motion assist device capable of assisting a travel motion of a user without causing any discomfort, and has a high level of versatility. A travel motion assist device includes an assist drive unit configured to be worn on a prescribed joint of the user required for the travel motion of the user, and to be driven in a corresponding manner, a torso motion detection unit configured to be worn on a torso of the user, and to detect the displacement of a center of gravity C indicating the movement of the torso, and a control unit configured to control an operation of the assist drive unit, wherein the control unit estimates a phase of the travel motion of the user according to a detection result of the torso motion detection unit, and drives the assist drive unit at a prescribed phase.
