Simultaneous transmission of audio and video signals using visible light communications

, 2013
A visible light communication system for parallel transmission of high-quality audio and video signals using illumination white and red light-emitting diodes (LEDs) is presented in this paper. For video transmission, we adopts the pulse width modulation (

Sensitivity of Hands to Visible Light [PDF]

Nature, 1964
RECENTLY, reports have appeared in the press of experiments demonstrating the existence of a dermal sensitivity to intensities and wave-lengths of visible light. Many of the experiments do not appear to have precluded thermal effects, and B. Konstantinov has suggested1 that the results may be explained by the perception of reflected infra-red radiation

Nanocouplers for Infrared and Visible Light [PDF]

Advances in OptoElectronics, 2012
An efficient and compact coupler—a device that matches a microwaveguide and a nanowaveguide—is an essential component for practical applications of nanophotonic systems. The number of coupling approaches has been rapidly increasing in the past ten years with the help of plasmonic structures and metamaterials. In this paper we overview recent as well as

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
