Abstract:
A walking training apparatus includes a first wire winding mechanism configured to pull a wire connected to a leg upward and forward, and control means. The control means performs at least one of control, in a leg-idling period, so as to make the first wire winding mechanism generate a driving force obtained by adding a second driving force for reducing a loss of the pulling force of the first wire winding mechanism caused by mechanical friction in the first wire winding mechanism to the first driving force, and control, in a leg-standing period, so as to make the first wire winding mechanism generate a driving force obtained by subtracting the second driving force for reducing the loss of the pulling force of the first wire winding mechanism caused by the mechanical friction in the first wire winding mechanism from the first driving force.
Abstract:
Embodiments disclosed herein relate to a garment system including at least one sensor, and at least one actuator that operates responsive to sensing feedback from the at least one sensor to selectively constrict or selectively dilate at least one flexible compression garment. Such selective constriction or dilation of the at least one flexible compression garment against at least one body part can improve muscle functioning or joint functioning during an activity, such as a sport or other activity.
Abstract:
A frame assembly including a first longitudinal member, a second longitudinal member spaced apart from the first longitudinal member, a third longitudinal member configured to diagonally connect the first longitudinal member and the second longitudinal member, a plurality of first distance maintaining members configured to connect the first longitudinal member and the second longitudinal member, and a plurality of second distance maintaining members configured to connect the second longitudinal member and the third longitudinal member is disclosed.
Abstract:
A power transmission device (100) comprising a first transmission (110) configured to receive a power from an input device (200); a second transmission (130) configured to deliver the power to an output device (500); and connecting unit (120) configured to connect the first power transmission unit and the second power transmission unit, and to deliver a pressure of a transfer fluid occurring due to the first power transmission unit to the second power transmission unit. A motion assistance device (10) comprising a driver (210) configured to mount to a user at a position corresponding to a proximal part of the user, and to generate a power; a joint assembly (400, 600) corresponding to a distal part of the user, the joint assembly configured to provide an assistance force to the user based on the power; and a power transmission device (100).
Abstract:
Provided is a pelvis fixing device including a rear fixing module (110) including a driving module mounting portion, the rear fixing portion (110) configured to enclose a side surface and a rear surface of a waist of a user, and a front fixing module (120) including a soft layer and a hard layer configured to enclose a front surface of the waist of the user, wherein the hard layer is connected to the rear fixing module to form a closed loop around the waist of the user.
Abstract:
A method and apparatus for protecting a circuit are provided. The method and apparatus may measure a physical quantity of a motor by an external physical stimulus, may calculate the related counter electromotive voltage generated by the motor, based on the physical quantity, may compare the counter electromotive voltage to an output voltage, and may open a circuit connected to the motor to be open when the counter electromotive voltage is greater than the output voltage. The protection method and apparatus is applied to a walking assistance apparatus.
Abstract:
A wearable action-assistance device is provided that can be fitted to and worn by various wearers who have different body types and sizes. A wearable action-assistance device (10) has a hip frame (11) that is to be worn on the hips of a wearer, a lower limb frame (12) that is to be worn on lower limbs of the wearer, and drive portions (13R, 13L, 14R, 14L) that are provided on the lower limb frame (12) in correspondence with joints of the wearer. The lower limb frame (12) has variable shape portions (41L, 41R, 42L, 42R, 43L, 43R, 44L, 44R, 45L and 45R) that can cause a plurality of places including portions in the vicinity of the drive portions (13R, 13L, 14R, 14L) to bend to the left and right to adjust flexion angles thereof. By being able to bend a plurality of places on the lower limb frame (12) to the left and right, the shape of the lower limb frame (12) can be adjusted so as to fit the leg shapes of even knock-kneed or bowlegged wearers.
Abstract:
In one exemplary embodiment of the present invention, an adjustable joint actuator assembly (60) for a medical assist device is provided. The assembly includes a support arm (24, 28) extending along a longitudinal axis (32), a gearbox (16) rotatably coupled to the support arm (24, 28) about the longitudinal axis (32) and slidable along the longitudinal axis (32), and a locking mechanism inserted over a portion of the support arm (24, 28) and the gearbox (16) to facilitate preventing movement of the gearbox (16) relative to the support arm (24, 28) along the longitudinal axis (32). The locking mechanism is configured for removal to enable movement of the gearbox (16) relative to the support arm (24, 28) along the longitudinal axis (32).
