Equation 5 · Part 4 · How Edge AI Electronics and Sensor Systems Actually Work
Symbol C
What this part means
a contrast threshold set by an analog bias current, and each event carries just an address, a timestamp, and a sign — brighter or darker — streamed out asynchronously on a shared digital bus rather than assembled into frames.
Its job in the formula
C is a part of this expression. Its role is fixed by the surrounding article and by the operations shown in the formula.
Where the article explains it
where C is a contrast threshold set by an analog bias current, and each event carries just an address, a timestamp, and a sign — brighter or darker — streamed out asynchronously on a shared digital bus rather than assembled into frames.
The passage around this formula
…local light intensity and fires an asynchronous digital event only when that log-intensity has moved by more than a threshold since the pixel’s last event. Formally, a pixel emits an event when . where C is a contrast threshold set by an analog bias current, and each event carries just an address, a timestamp, and a sign — brighter or darker — streamed out asynchronously on a shared digital bus rather than assembled into frames. This architecture was demonstrated in a foundational 128×128-pixel…

A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
