20110043112 | POWER CONTROL - An apparatus for driving a voltage source such as a discharge or LED lamp using a power booster receiving an AC voltage source configured through an inductor to turn on and off periodically in response to a duty cycle of a dimming control signal or a transformer starting a new cycle, for regulating a low voltage AC signal. The booster control circuitry adjusting the current feed to a determined target boost voltage according to sensed input from primarily a single comparator which compares any one of (but not limited to) a) the output boosted voltage, b) the globe current, or c) the inductor input current. | 02-24-2011 |

20150145582 | PULSE GENERATING CIRCUIT FOR AUDIO-FREQUENCY AMPLIFIERS AND REGULATED POWER SUPPLIES - A circuit for generating a series of pulses in response to a first signal, the circuit comprising: a lossy integrator which receives a second signal as its input; and a comparator which: receives the output of the lossy integrator at one of its inputs; and receives the first signal at the other of its inputs. This circuit can be incorporated into, for example, audio-frequency amplifiers and regulated power supplies. | 05-28-2015 |
