| 20090315465 | METHOD FOR PROTECTING A LAMP CIRCUIT AND RELATED WIRING - A method for controlling a lamp circuit that includes: setting a first voltage threshold and a first time window within a control circuit corresponding to a characteristic of a first lamp type; providing a first signal through the lamp circuit to start a first time interval and create a first test voltage; comparing the first test voltage to the first voltage threshold; and operating a switch to couple an output of the lamp circuit to a source of electrical power if the first test voltage is greater than or equal to the first voltage threshold before the first time interval exceeds the first time window. | 12-24-2009 |
| 20090015066 | CLOSE-LOOP RELAY DRIVER WITH EQUAL-PHASE INTERVAL - A power distribution system generally includes at least two relays. An equal-phase pulse generator generates pulse signals in equal phase intervals. At least two drivers, one for each of the at least two relays, control current flow to the at least two relays based on the pulse signals. | 01-15-2009 |
