Abstract: A combined lamp and air purifier system designed to remove odors, germs, and bacteria from the air while providing illumination is disclosed. The system includes a shell, a fan unit with air inlets, an air filter, and an illumination source capable of emitting UV-C light for air disinfection. The air filter captures the airborne pollutants and expels the purified air. The system can be powered by various means, including light sockets, lamp fixtures, and vehicle lighter ports. The system features a control button for manual operation, a wireless transceiver for remote control, and may include an air freshener module in vehicle versions. The system is designed for easy installation and maintenance, offering an efficient solution for air purification and lighting in diverse environments.

Abstract: Near infrared imaging using elastic light scattering and tissue autofluorescence are explored for medical applications. The approach involves imaging using cross-polarized elastic light scattering and tissue autofluorescence in the Near Infra-Red (NIR) coupled with image processing and inter-image operations to differentiate human tissue components.

Abstract: The invention comprises a method for producing optical thin films with a high laser damage threshold and the resulting thin films. The laser damage threshold of the thin films is permanently increased by irradiating the thin films with a fluence below an unconditioned laser damage threshold.
