20120112710 | Electric machine to regulate work output rotational speed from infinitely variable transmissions by the creation of electrical energy - The present application relates to an electric machine to regulate the rotational work output speed from an Infinitely Variable Transmission, hereafter noted as IVT, or a Continuously Variable Transmission, hereafter noted as CVT. This application to regulate the work output rotational speed from an IVT or CVT by creating electrical energy may, for explanatory purposes, apply to mechanical gear boxes where it is possible, while holding the input rotational speed constant, to change the work output rotational speed by changing the rotational speed and/or direction of a second rotating shaft.

These descriptions are not to limit the scope of this application, but to provide the reader with a sense of what is intended. Since the most common application relating to this device will result in the generation of electrical energy, this energy may be directed, for example, to power the electric supercharger as in patent application Ser. No. 12/802,348, or, in another example, to supply electrical energy to the electric side of a hybrid type of application, and/or power other engine accessories. | 05-10-2012 |

20120194142 | POWER GENERATING DEVICE AND BRAKING DEVICE - Power generation efficiency is improved with a simple configuration. A braking device is provided with a brake rotor which rotates on a central axis, and friction portions which are in frictional contact with the brake rotor. A coil is wound around the outer peripheral portion of the brake rotor. A friction portion has the north pole of a magnet, and a friction portion has the south pole of a magnet. The braking device generates electricity by using an electromagnetic induction phenomenon and an electrostatic phenomenon that are caused by the interaction between the outer peripheral portion and the friction portion, for example, at the time of braking. As a result, the configuration can be simplified and the amount of power generation is not likely to be limited by a motor capability because there is very little need to use the motor as a generator. Furthermore, the friction energy itself converted from the kinetic energy of the brake rotor can be converted into electrical energy to suppress the friction energy from being lost as heat energy. | 08-02-2012 |
