20120142497 | TRAINING SYSTEM - A training system for training of part of a trainee's body includes a training machine, a control device controlling the training machine, and a display unit displaying a game screen. The training machine imposes a load on the trainee, with an MR-fluid load generating unit using MR fluid, which has viscosity varying with a magnetic field strength. The load is calculated on the basis of a target load and a relationship between the current in the MR-fluid load generating unit and the load generated by the MR-fluid load generating unit. The control device produces the game screen in correspondence with the trainee's training motion detected by a displacement detection sensor, and makes the display unit display the game screen, while controlling the load in the training machine. | 06-07-2012 |

20100295533 | PASSIVE INTERMODULATION DISTORTION MEASURING METHOD AND SYSTEM - According to a reception passive intermodulation measurement method of the present invention, a device under test is set to the mismatching condition, and a standing wave is generated on a transmission line where the sample is connected. Since the tip of the transmission line is short-circuited using the sample, the sample is positioned at the anti-node of the standing wave, and test signals are applied at a high current density. System noise is calibrated with the tip of the transmission line being open. Since impedance matching is not required and terminators are not employed, a large measurement dynamic range is obtained without being affected by passive intermodulation that is generated in terminators. The sample is very small, and an arbitrary shape can be selected. The property measurement is enabled for a wide range of materials, regardless of a conductive material, an insulating material and a magnetic material. | 11-25-2010 |
