Intelligent Non-Conventional Applications of LEDs

Neurological and psychological applications of transcranial lasers and LEDs.

Transcranial brain stimulation with low-level light/laser therapy (LLLT) is the use of directional low-power and high-fluency monochromatic or quasimonochromatic light from lasers or LEDs in the red-to-near-infrared wavelengths to modulate a neurobiological function or induce a neurotherapeutic effect in a nondestructive and non-thermal manner. The mechanism of action of LLLT is based on photon...

Conventional and Non-conventional Presupposition

Presuppositions are very important in our understanding of how background and context determine the interpretation of a sentence. However, if we study some of the things that have been claimed to be presuppositions, we find that it is a very miscellaneous collection of things. Here are some examples: (1) Harry saw the man kiss her presupposes that Harry and the man denote uniquely existing, for...

Sensing Light with LEDs: Performance Evaluation for IoT Applications

The Internet of Things includes all the technologies allowing the connection of everyday objects to the Internet, in order to gather measurements of physical quantities and interact with the surrounding environments through telecommunication devices with embedded sensing and actuating units. The measurements carried out with different LEDs demonstrate the possibility of using these devices both...

Double-heterojunction nanorod light-responsive LEDs for display applications.

Dual-functioning displays, which can simultaneously transmit and receive information and energy through visible light, would enable enhanced user interfaces and device-to-device interactivity. We demonstrate that double heterojunctions designed into colloidal semiconductor nanorods allow both efficient photocurrent generation through a photovoltaic response and electroluminescence within a sing...
