| 20110257924 | SELF-MONITORING AND COMMUNICATING TRANSFORMER - A self-monitoring transformer is disclosed. The transformer uses sensors embedded in the coils to determine the expected lifespan of the insulation, as well as other operating parameters, and communicates that information to an external system. | 10-20-2011 |
| 20110187484 | Power Input Device with Current Pulse Multiplier Transformer to Reduce Harmonic Currents in Converter/Inverter Circuits and Devices, and Method of Making the Same - A power supply device comprising an advanced harmonic current quashing (AHQ) and current pulse multiplier (CPM) (AHQ/CPM) three-phase transformer having: a primary winding placed around a magnetic core and having three primary winding input leads to connect a three phase power supply; and a plurality of secondary windings placed around the magnetic core in a predetermined winding turns configuration to generate a plurality of three phase outputs, where each three phase output of the plurality of three phase outputs has a different phase angle from all other three phase outputs, with each unique phase angle associated with a three phase output of a corresponding secondary winding being determined based on the winding turns configuration utilized for the corresponding secondary winding. A variable frequency drive (VFD) having 3N converters/inverters coupled to the secondary windings outputs exhibit substantially reduced harmonic currents and a current pulse number of greater than 6N. | 08-04-2011 |
| 20100188026 | Starter Stopper for High Intensity Discharge Lighting - A starter stopper for use with a high intensity discharge (HID) lighting source includes a timer and switch. The timer controls the durations of on-time and off-time periods during an energizing period. The starter stopper connects the HID lighting source to power to start the HID lighting source during on-time periods, and disconnects the HID lighting source from the power to start the HID lighting source during off-time periods. A method of starting and stopping an HID lighting source includes initiating an energizing period in response to application of power to a starter stopper, enabling the HID lighting source to be connected to power to start the HID lighting source during on-time periods by the starter stopper, enabling the HID lighting source to be disconnected from the power to start the HID lighting source during off-time periods by the starter stopper, and stopping the energizing period in response to removal of the power to the starter stopper. | 07-29-2010 |
