Patent 7759826 was granted and assigned to Yazaki North America on July, 2010 by the United States Patent and Trademark Office.
A connector state control module includes a sensing module that determines a state of a pulse width modulation (PWM) signal. A charge switching module selectively provides a voltage based on the state of the PWM signal. A charge storage module stores a charge based on the voltage. A power supply switching module selectively outputs a power signal based on the charge.
