1) Emitter coupled logic 
[data-centric programming language] ECL is a declarative, data centric programming language designed in 2000 to allow a team of programmers to process big data across a high performance computing cluster without the programmer being involved in many of the lower level, imperative decisions. == History == ECL was initially designed and devel...
(1) Electrochemiluminescence. production of light during an electrochemical reaction, now being applied to various bioassay systems. (2) Enhanced chemiluminescence. Method for enhancing detection of proteins on blots. Involves the use of luminol that is oxidized by peroxidase-coupled antibody used to detect the protein of interest, and the light produced is then detected on film.
...Emitter Coupled Logic
Emitter Coupled Logic - a style of extremely high speed logic (now superceded for most applications). The signals for ECL are normally constrained to be a single long trace starting at the driving pin, through input pins, and finally terminating resistors
