Abstract:
A broad range of brightness in a fluorescent lamp may be achieved by applying low-frequency, pulse-width modulated voltage or current to the lamp for a low level of brightness, or high-frequency voltage or current for a high level of brightness. Switching is provided to select between the two signals.
Device And Method For Controlling The Temperature Of A Thin Film Resistive Heater
A circuit for controlling the temperature of a thin film conductive heater includes a control circuit for applying a voltage to the heater. The control circuit regulates the temperature of the heater element by using a modeling technique which assumes that the thin film coating functions as a single electrical resistor.
Ronald Welch, assistant attorney general for legislative affairs, responded that Justice Department officials were still discussing how to provide any "sensitive law enforcement information" regarding the FBI and DEA to congressional investigators. Without specifically acknowledging that cartel lead
