redundancy · engineering
A second system whose parameter has a window that overlaps the first, so that drift in the parameter can leave one window while remaining in the other.
Examples
- The Hubble Space Telescope's gyroscopes include backup units that activate when primary gyro drift exceeds operational thresholds. engineering
- The human body maintains blood pH between 7.35 and 7.45, with kidneys and lungs providing overlapping regulatory mechanisms. biology
- Amazon Web Services routes traffic through multiple availability zones, each with independent power and cooling systems. computing
Emergence
through: Two organized systems maintain function through parameter drift because a parameter can leave the range of the first but remain within the range of the second, enabled by temporal succession and overlapping windows in time.
- overlapping tolerance bands
- continuous functionality despite drift
- temporal system succession
