A LED–LED-based photoplethysmography sensor
Physiological Measurement, 2007A high sensitivity, low power and low cost sensor has been developed for photoplethysmography (PPG) measurement. It uses standard light emitting diodes (LEDs) as both light emitter and detector, pulse-based signal conversion techniques instead of the classical analogue-to-digital convertors (ADCs) and a general purpose microcontroller for the ...

Imagine an LED that turns itself on and off in response to light levels, or one that you can blow out like a candle. These are circuits you can build with just an Arduino, a resistor, an LED and a little code. In this workshop, we examine some surprising properties of LEDs to create systems that sense light, temperature and wind.

LEDs and Use of White LED for Lighting
2014LED is an acronym for “light emitting diode.” The first important fact is that LED is an electronic component, a diode, a component that can conduct current in one direction and not the other. As many other electronics components, controlling a LED is an easy topic, in order to obtain different behavior. Due to the fact that a LED must produce light, a

Not “wage-led” versus “profit-led,” but investment-led versus consumption-led growth
Journal of Post Keynesian Economics, 2015Abstract:This paper offers a critique of the concepts of “wage-led” and “profit-led” growth based on an application of the circuit of capital macroeconomic framework. Wages are shares of capital outlays sustaining production and circulation of goods; profits are shares of sales.

LED-to-LED visible light communication networks
Proceedings of the fourteenth ACM international symposium on Mobile ad hoc networking and computing, 2013Visible Light Communication (VLC) with Light Emitting Diodes (LEDs) as transmitters and receivers enables low bitrate wireless adhoc networking. LED-to-LED VLC adhoc networks with VLC devices communicating with each other over free-space optical links typically achieve a throughput of less than a megabit per second at distances of no more than a few ...

In pre-war Japan, kimonos were encoded with clues indicating gender, caste, age, class, and social ranking. Geographical location defined the colors, as certain plants that produced particular colors only grow in certain regions. Silk techniques are also regional, and the difference between fine and rough silk indicated relative wealth.
