20080094039 - Control apparatus for automotive alternator with function of initialization state detection: A control apparatus controls power generation of an electric generator and communicates with an external control apparatus. The control apparatus includes a receiver, a controller, an initialization state detector, and a transmitter. The receiver receives a command signal transmitted by the external control apparatus. The controller controls power generation of... Agent: Oliff & Berridge, PLC

20080088282 - Control system for controlling output of power generator: In a control system for controlling a power generator based on a command value associated with a control parameter, a receiver receives the command signal, a detector detects the command value included in the received command signal, and a determiner determines whether a duration of the detected command value being... Agent: Oliff & Berridge, PLC

20080084192 - Method for amplifying energy temperature-sensitive fluid and converting it into power generating energy: Into a temperature-sensutive magnetic fluid in a mixture layer state, 0.01-5 vol % of argon gas based on the volume of the structure of the temperature-senstive magnetic fluid is injected, and the mixture is irradiated with microwave or high frequency millimeter wave and placed in an external magnetic field by... Agent: Buhei Kono

20080084190 - Method and system for communicating voltage regulator switching information to a vehicle computer: A method for communicating voltage regulator switching information to a vehicle computer includes generating a first output signal from a voltage regulator, the first output signal configured to regulate a field current of a generating device associated therewith. A second output signal is generated from the voltage regulator, the second... Agent: Cantor Colburn, LLP

20080084191 - Method and system for protecting voltage regulator driver circuitry during field coil short circuit condition: A method for protecting voltage regulator driver circuitry during a short circuit condition of an alternator field coil includes passively detecting a drop in field coil voltage during an on-portion of a duty cycle of the field coil voltage, wherein the passive detection of the drop in field coil voltage... Agent: Cantor Colburn, LLP
