"It is my heart-warmed and world-embracing Christmas hope and aspiration that all of us, the high, the low, the rich, the poor, the admired, the despised, the loved, the hated, the civilized, the savage (every man and brother of us all throughout the whole earth), may eventually be gathered together in a heaven of everlasting rest and peace and bliss, except the inventor of the telephone. "
Mark Twain ; Christmas greetings, 1890

| Number | Title | Issue Date |
| 7388347 | Method and inverter for controlling a direct current motor A three-phase direct-current motor is controlled by cyclically repeating three first switching states. In each of the three first switching states, one of the three phases of the direct-current motor is periodically switched over between a first and a second input v... | 06/17/2008 |
| 7276831 | Split-pole field-match motor An electric motor having a plurality of rotor and stator poles, the poles of one element being alternately polarized and neutralized due to the use of direct current and alternating current windings on each pole. The poles of like current are connected in series, an... | 10/02/2007 |
| 7078872 | System and method for conditioning a signal A method of conditioning a signal being communicated between a system to be controlled and a controller may include monitoring an actual output signal and conditioning the actual output signal. The method also includes determining the difference between the actual o... | 07/18/2006 |
| 6756763 | Sensorless induction motor control A method for controlling an induction motor using an equivalent circuit model, the equivalent circuit having a real component and an imaginary component, is disclosed. The method instead of measuring a plurality of induction motor parameters, the real and the imagin... | 06/29/2004 |
| 5796233 | Multiple-stator induction synchronous motor An induction synchronous motor comprises: a unitary rotor having a first and a second rotor core; a first and a second stator mounted surroundingly facing the first and the second rotor core; a voltage phase shifting means for producing a first and a seco... | 08/18/1998 |
| 4928051 | Electric motor An electric motor has a rotor and a stator each of which is provided with a polyphase winding. The rotor and stator have the same number of poles but the number of phases in the winding of the rotor differs from that in the winding of the stator. The moto... | 05/22/1990 |
| 4742288 | Control system for AC motor/generator of secondary AC excitation type A control system for controlling the load of an AC motor/generator of secondary AC excitation type connected to a power system in parallel to at least a synchronous machine. The AC motor/generator has the secondary excitation winding thereof controlled in... | 05/03/1988 |
| 4500826 | Variable speed electric induction motors without brushes A variable speed induction motor includes a photo-electric cell which controls the current delivered the rotor induction coils. The control is effectuated by the use of controlled diodes, the control electrodes of which are electrically connected to the p... | 02/19/1985 |
