  • TRAINING DEVICE
    Publication number: 20160074271
    Abstract: A training device for training a limb includes target parts to be touched with the limb and a force generator that generates a lifting force acting upward on the limb by electricity in a manner allowing the limb to move upward and downward.

  • TRAINING DEVICE
    Publication number: 20160074270
    Abstract: A training device is for training a limb. The training device includes switches that are manipulated with the limb and a load reliever that generates a counter force against the weight of the limb in a manner allowing the limb to move upward and downward.

  • Apparatus for controlling magnetic levitation system
    Patent number: 6359767
    Abstract: A control apparatus in a magnetic levitation system for controlling attraction and/or repulsion forces created from a pair of electromagnets to levitate an object therebetween at a predetermined target position in a contactless manner, in response to a displacement of the object from the target position. The control apparatus includes a start/stop detector, a phase compensation circuit, an integrator, and a switching circuit. The start/stop detector detects a start and stop of a levitation control procedure and generates a control signal having a predetermined time duration when either of the start and stop of the levitation control procedure is detected. The compensation circuit provides a compensation signal to compensate AC currents flowing through the electromagnet so that the displacement of the object from the target position becomes zero. The integrator integrates the compensation signal.
