Active control for street lights to minimize light pollution
RPI ID: 2018-053-401 Innovation Summary: This system reduces sky glow by monitoring cloud coverage and adjusting outdoor lighting output when clouds are at or below a set threshold. A control unit receives sensor data, decides against a policy whether to dim and shift spectra, and commands light sources capable of variable intensity and wavelength....

Use of Integrating Sphere Technology To Provide Uniform, High-intensity Light and Wavelength Mixing from Light Emitting Diodes
Current State of the Art: Since 2000, photoactive composites material used in fillings have become widespread in restorative dentistry. Cosmetically appealing, these white fillings have become the standard, increasing from approximately 68 million composite fillings in 1999 to close to an estimated 100 million procedures in 2011. Crowns remain...
