Abstract:
An actuator system for extending and flexing a joint, including a multi-motor assembly for providing a rotational output, a rotary-to-linear mechanism for converting the rotational output from the multi-motor assembly into an extension and flexion of the joint, and a controller for operating the actuator system in several operational modes. The multi-motor assembly preferably combines power from two different sources, such that the multi-motor assembly can supply larger forces at slower speeds (“Low Gear”) and smaller forces at higher speeds (“High Gear”). The actuator has been specifically designed for extending and flexing a joint (such as an ankle, a knee, an elbow, or a shoulder) of a human. The actuator system may, however, be used to move any suitable object through any suitable movement (linear, rotational, or otherwise).
Abstract:
A bathtub 12 is supported by a movable unit 14 that vertically moves by the driving power of a motor and by rollers 13 running on a guide slope 15. When not used, the bathtub 12 is stored under a tank 11 in a close to upright position, so that the bathing aid occupies only a small space when not used. To use the bathing aid, the movable unit 14 is lowered and, accordingly, the rollers 13 roll down the guide slope 15. With this motion, the bathtub 12 changes its orientation from a position where the open top of the bathtub 12 is directed obliquely forward to a position where the open top is directed almost upward. The bathtub 12 is automatically driven by the electrical driving power of the motor; the caregiver has only to make some key operations. Thus, the workload on the caregiver is significantly reduced.

PROBLEM TO BE SOLVED: To provide an actuator system capable of minimizing or avoiding extra costs and mechanical complexity.SOLUTION: An actuator system 100 for extending and flexing a joint 110 includes a multi-motor assembly for providing a rotational output, a rotary-to-linear mechanism for converting the rotational output from the multi-motor assembly into an extension and flexion of the joint, and a controller for operating the actuator system in plural operational modes. The multi-motor assembly combines power from two different sources so that the multi-motor assembly can supply larger forces at slower speeds (Low Gear) and smaller forces at higher speeds (High Gear). The actuator is specifically designed for extending and flexing a joint 110 (such as an ankle, a knee, an elbow, or a shoulder) of a human. The actuator system 100 may be used to move any suitable object through any suitable movement (linear, rotational, or otherwise).
Abstract:
An apparatus for applying traction force to a spine of a user has a chassis with an upper surface. A user lies on the upper surface with the spine extending generally parallel to a longitudinal axis of the chassis. Two members extend from the chassis on opposing sides of the longitudinal axis, each member being positioned to engage an armpit. A lever is pivotally attached to the chassis for rotation about a lateral axis, and a pad coupled to the lever contacts a proximal portion of each upper leg when the leg is bent forward at a hip joint. A force applied to the lever is transmitted through the pad to each upper leg and opposed by the members, thereby applying traction force for decompressing the spine. The force may be applied by the arms of the user or by a motor.
Abstract:
A method of operating an exoskeleton device includes: receiving sensor information; connecting a clutch system to a pulley system in; determining whether to engage a drive train gear to the clutch system based on the sensor information; engaging the drive train gear through the clutch system when determined to engage the drive train gear; and powering a first motor to drive the drive train gear for controlling a joint or segment of exoskeleton device.
Abstract:
A handheld massage device that may be employed to provide therapeutic massage to a user's backside includes a user-grippable, generally hook-shaped handle and a massage tool mounted at one end thereof. The massage tool has a plurality of body-contacting work elements that may be selectively moved into operative position and locked in place. A releasable, spring-loaded locking mechanism is provided between the handle and the massage tool so that the tool is locked in position when engaged and unlocked and rotatable when disengaged. The handle may be formed as an integral piece or in segments that can be assembled in end-to-end relation or disassembled and compactly folded for storage. In segmented form, a resilient line may extend internally within tubular segments between the respective end segments to securely hold the handle segments together and cooperating parts axially and rotationally align the separable segments when assembled.
Abstract:
A wearable apparatus for the treatment or prevention of osteopenia or osteoporosis, stimulating bone growth, preserving or improving bone mineral density, and inhibiting adipogenesis is disclosed where the apparatus may generally comprise one or more vibrating elements configured for imparting repeated mechanical loads to the hip, femur, and/or spine of an individual at a frequency and acceleration sufficient for therapeutic effect. These vibrating elements may be secured to the upper body of an individual via one or more respective securing mechanisms, where the securing mechanisms are configured to position the one or more vibrating elements in a direction lateral to the individual, and the position, tension, and efficacy of these vibrating elements may be monitored and/or regulated by one or more accelerometers.

Abstract:
An exercise device for simulated swimming strokes is disclosed. A cabinet supported on a frame serves as a base and has a body supporting platform thereabove, one portion supporting the torso and parallel duplicate hinge portions supporting the legs of the user. The user's arms reciprocate cable means and the user's legs reciprocate pivotal push rods extending into the cabinetry for rotating power consuming means comprising independent arm and leg powered fly wheels respectively connected to arm and leg powered means.
Abstract:
Systems and methods for assistive devices for replacing or augmenting the limb of an individual, such devices comprising a joint and a powered system; the powered system having a first configuration in which the powered system rotates the joint by applying power to the joint, and a second configuration that allows for rotation of the joint without actuation of the powered system.
