The present invention provides a safety training device capable of being attached to an existing front-wheeled walker. The safety training device a modified ski unit, a braking mechanism, a brake cable and hose. When improper transfer techniques are utilized by a patient, the modified ski unit engages the brake and cable hose to exert a force to the braking mechanism. The braking mechanism activates a braking member on the wheel of the walker, halting further movement of the patient and walker. Simultaneously, a striking member of the braking mechanism makes contact with the frame of the walker, producing an audible cue, alerting the patient and any healthcare professionals present that improper technique is being used in a transfer.

An overspeed brake system for use in an elevator powerhead is provided. A brake rotor is attachable to a cable drum to rotate with a cable drum. A brake member selectively engages the brake rotor upon transition of an actuation lever from a first position to a second position. A biasing member acts on the actuation lever to bias the actuation lever from the first position towards the second position. A latch arrangement has a first orientation maintaining the actuation lever in the first position and a second orientation releasing the actuation lever for transitioning from the first position to the second position. The latch arrangement transitions from the first orientation to the second orientation when a speed sensing arrangement senses that the rotational speed of the cable drum is at least a predetermined rotational speed.

A braking mechanism for an electric motor includes an electromagnet configured to be selectively energized in response to a control signal. The braking mechanism also includes a first braking member coupled for co-rotation with an output shaft of the electric motor. The first braking member is configured to movable relative to the output shaft between a first position and a second position. The braking mechanism also includes a second braking member rotationally fixed relative to the first braking member. When the electromagnet is energized, the electromagnet causes the first braking member to move from the first position to the second position. The first braking member engages the second braking member to brake the electric motor in one of the first position or the second position.

Methods and corresponding control devices for releasing an electric actuator in a reliable manner, such as an electric parking brake in particular, in a motor vehicle brake system. The aim of the invention is to provide an improved function and architecture which helps prevent the disadvantages of open-loop control systems when using a rationalized sensor system, thereby obviating closed-loop control systems. This is achieved by a release method and a corresponding electronic control unit which obtains an especially modulated change in the power requirement during the release process upon impacting the quasi-elastic release end stop of the electric actuating unit such that the change is fed back, the change being detected in order to be used as information for a power interruption or a termination of the power supply to the electric actuating unit.
