Latest Patents

Benard’s listed patents address two distinct areas of applied physics and engineering.

“Fluorescent Lamp with Improved Efficiency” describes powering a fluorescent lamp with alternating positive and negative current pulses shaped so that the absolute current increases during each pulse. The patent also details a switched-mode drive circuit using transformers, switches, a diode, and a capacitor. A digital control circuit sequences the switches to produce the desired current waveform.

“Method for Generating Electronically Excited NF for Use in a Laser” describes producing electronically excited nitrogen fluoride, or NF*, by dissociating fluoride azide. The disclosed approaches include reacting fluoride azide with vibrationally excited molecules, laser pumping, and detonation. The resulting excited species may support short-wavelength laser operation, either through an NF transition in a resonant chamber or by transferring stored energy to an emitting species such as BiF.
