Pictures taken with most camera flashlights are often considered unnatural looking due to a mismatch of the illuminance and color temperature between the flash light and the ambient light in the scene. Subsequently, image rendering software is used to enhance the picture to a desirable look or several pictures must be taken attempting a better capture. A smart light system has been developed, incorporating LED sources and a sensor, that studies the lighting environment and decides optimal light for specific applications.

Tunable photocapacitive optical radiation sensor enabled radio transmitter and applications thereof

This technology relates to highly sensitive and large area optical sensor arrays with smart control that feature wireless operation. The optical sensors convert sensed illumination into a corresponding impedance (e.g., capacitance, inductance, etc.). The resulting impedance can then be easily integrated into a wireless signal generator (e.g., an LC or tank circuit), such that a characteristic of the illumination (e.g., intensity, wavelength, etc.) can be translated into a wireless output.


Laboratory courses are a vital part of engineering and scientific education and training, but so far, lab courses have been considered impractical for remote education. Lab courses are traditionally conducted at a central location, with student, instructor, and experiment in close proximity to each other. As versatility of communications over the Internet increases, it is desirable to have a method to remotely conduct a lab experiment that allows a student to easily access the experiment from a remote location.
