The emergency stop device is coupled to the switch and arranged to move the switch from the closed position to the open position. The reset actuator is coupled to the switch and arranged to move the switch from the open position to the closed position, wherein the reset actuator is controllable to move the switch from the open position to the closed position.

Overhead lift systems and methods

An overhead lift system may include a motor and a lift strap connected to the motor. The motor raises and lowers the lift strap. A hand controller may be communicatively connected to the motor. The hand controller includes a force sensor associated with the body of the hand controller such that force applied to the body is detected with the force sensor. An orientation sensor may also be arranged within the body and determines an orientation of the hand controller. A control unit may be communicatively connected with the motor, the force sensor, and the orientation sensor. The control unit detects a force applied to the hand controller with the force sensor, determines a direction of motion of the hand controller with the orientation sensor, and provides a signal to the motor to raise or lower the lift strap based on the force and orientation of the hand controller.

A person lifting apparatus includes a strap movement system. The person lifting device includes a housing and a lifting strap feeding device located in the housing. The lifting strap feeding device includes a motor connected to a drum and a lifting strap wound on the drum. A sensor provides a signal indicative of force on the lifting strap. A controller receives the signal from the sensor. The controller controls operation of the motor based on the signal. A user input is used to place the strap movement system in a fast mode during which the controller speeds up operation of the motor from a normal operating speed.

Apparatus for unloading a user's body weight during a physical activity of said user, particularly for gait training of said user

The invention relates to an apparatus (1) for unloading a user's body weight during a physical activity of said user (4), particularly for gait training of said user (4), comprising: a plurality of ropes (41, 42, 43, 44), wherein each rope (41, 42, 43, 44) extends from an associated drive unit (510, 520, 530, 540), is deflected by a passively displaceable deflection device, e.g. a device that is displaceable by means of the forces in the deflected ropes, and then runs to a first free end (41 a, 42a, 43a, 44a) of the respective rope (41, 42, 43, 44), and a node (60) being coupled to said first free ends (41 a, 42a, 43a, 44a) and being designed to be coupled to said user (4), wherein the drive units (510, 520, 530, 540) are designed to retract and release the respective rope (41, 42, 43, 44) so as to adjust a current rope force (FR) along the respective rope (41, 42, 43, 44), which current rope forces add up to a current resulting force (F) exerted on said user (4) via said node (60) in order to unload the user (4) upon said physical activity. Further, the invention relates to a method for controlling such a system.
