Abstract:
A system includes a vibration unit that provides independent adjustability of vibration characteristics such as frequency and amplitude and may provide a first motor that rotates an eccentric and can adjust vibration frequency and a second motor that that may move the eccentric within the vibration unit in a manner that adjusts amplitude of the vibration.
Abstract:
Examples of a motion system are disclosed. The motion system comprises a plurality of Stewart platform based actuators connected one to each another forming a desired modular configuration. Each of the plurality of actuators is controlled by a central controller that is configured to independently control the plurality actuators and adjust in real time their position, orientation and motion trajectory. The plurality of actuators are arranged in the desired configuration, shape and size to provide motion system that can mimic a natural motion/gait of human or animal body.
Abstract:
Techniques and devices for extending a piston, for example connected to a medical device such as a mechanical CPR device, to accommodate different sized patients, are described herein. In some cases, a piston of a mechanical CPR device may include an inner piston at least partially slidable into an external piston sleeve. In one aspect, an external piston spacer may be attached to an outward surface of the inner piston to extend the length of the piston. In another aspect an internal bayonet sleeve may contact one or more locking rods at various positions, enabling adjustment of the length of the inner piston. In yet another aspect, a piston adapter may be removably attached to the end of the piston. In all aspects, the change in length of the piston may be detected and used to modify movement of the piston, for example to more safely perform mechanical CPR.

Applicator (1) and capsule (17) for such applicator. A capsule (17) for distributing, on a surface of a living body, a product containing an active component or forming a cosmetic product, the capsule having a product distribution zone and comprising: —in a body, a supply of product which is in communication with the product distribution zone, and —first linking means (150, 511a, 511b) for removably securing the capsule to second linking means of a housing (15) in which is disposed a light source (9).
Abstract:
In at least one aspect, there is provided a system for generating force about one or more joints including a soft exosuit having a plurality of anchor elements and at least one connection element disposed between the plurality of anchor elements. The system also includes at least one sensor to determine a force the at least one connection element or at least one of the plurality of anchor elements and to output signals relating to the force, at least one actuator configured to change a tension in the soft exosuit and at least one controller configured to receive the signals output from the at least one sensor and actuate the at least one actuator responsive to the received signals.
Abstract:
A gait rehabilitation machine and a method of using the same for lower-limb rehabilitation. The gait rehabilitation machine includes: a frame; a rear supporting member provided at the frame so that the back side of a human body can lean against the rear supporting member; a thigh supporting member corresponding to a thigh of the human body and pivotally connected to the frame; a shank supporting member corresponding to the corresponding shank of the human body, pivotally connected to the thigh supporting member, and having a pedal to be stepped on by the human body; a knee supporting member corresponding to the corresponding knee of the human body and provided at the thigh supporting member or the shank supporting member; and a transmission device for driving the shank supporting member to move. Thus, a patient can do lower-limb gait rehabilitation exercise without using a suspension system.
Abstract:
An adjustable support apparatus for a user includes a cover defining a user-facing surface, at least a portion of the user-facing surface defining a plurality of raised members each defining a distal end, wherein the distal end of each raised member defines a planar surface. The apparatus includes an adjustment mechanism at least partially enclosed by the cover. The adjustment mechanism is structured to be urged toward or away from the user so as to urge the user-facing surface and plurality of raised members toward or away from the user, respectively, so as to increase or decrease, respectively, the spacing between the distal ends of the raised members to thereby increase or decrease, respectively, the force exerted by the raised members against the user so as to impart a stretching or lengthening effect or contraction effect, respectively, on the vertebral column and intervertebral discs of the user.
Abstract:
An apparatus (1) for assisting cardiopulmonary resuscitation by applying compression to the chest of a patient to stimulate blood circulation. The apparatus (1) comprises a pressurized gas container (70), preferably storing a gas in liquid form, a turbine (90), an electrical power generator (91) and a defibrillator (80). The turbine is actuated by the pressurized gas and adapted for powering the electric power generator (91), and the electric power generator (91) is adapted for energizing the defibrillator (80). The apparatus may further comprise a pneumatic compressor assembly (10) operably connected to the pressurized gas container (70).
Abstract:
The invention is directed to controlling a hydraulic actuation system having at least one degree of freedom, a prime mover, at least one actuation module and a controller, with each actuation module including: an over-center variable displacement pump having a power input connection configured to power the pump from the prime mover and a displacement varying input for varying the displacement of the pump; a displacement varying actuator configured to modulate the displacement varying input of the pump; an output actuator in direct communication with the pump, the output actuator configured to drive a corresponding degree of freedom; and at least one sensor establishing a feedback measurement that represents a force or motion of the output actuator. Based on a value of each feedback measurement, the force or motion of the output actuator is regulated by controlling the prime mover and the displacement actuator for the output actuator.
Abstract:
A walking assistant device may calculate a walking cycle by measuring only motion of a specific joint without a force/torque sensor (F/T sensor) of a foot, and a method of controlling the walking assistant device. The method may include measuring motion of a hinge to which different support frames are connected; overlapping a reference trajectory corresponding to the measured motion and modulation trajectories that have been modulated from the reference trajectory; correcting the overlapping trajectory to correspond to the measured motion; determining assistant torque corresponding to a phase of the corrected trajectory; and providing the determined assistant torque to the support frame.
