White Papers
Longer papers on error budgets and what a specification costs.
Unlimited Rotation, Finite Electrical Margin
A rotary joint can turn freely while its electrical path still limits the system. Follow the current out and back, see why digital signals need more than continuity, and translate movement into a useful maintenance record.
The Better Stabilisation Ratio Can Give the Worse Result
A strong result at one frequency can hide motion amplification elsewhere. Compare two response curves against the same disturbance spectrum, then learn what evidence to request for a real camera installation.
A Precise Map Pin Can Share the Wrong Reference
A reservoir inspection example shows how bearing and range become a map position, why shared references can conceal offsets, and how correlation and two-dimensional coverage change the uncertainty region.
Why a Repeatable Positioner Can Still Point Wrong
A fine angle readout can hide a stable offset. Follow ten repeated returns to see what averaging improves, why correction uncertainty remains, and which test conditions make positioner specifications useful.
Why an Identical Replacement Can Bind in the Cold
Two housings can share the same dimensions at room temperature and give very different fits in service. Follow one material change through thermal movement, manufacturing tolerances and the evidence needed to release a supported replacement.
It Passed After the Heat. Did It Work During the Heat?
A device can recover at room temperature and still miss its operating requirement when hot. Learn how test timing, mounting and the decision rule change what an environmental report can support.
The Encoder Is Right. The Optics Have Moved.
A joint encoder measures the angle between its own mounting parts. Trace the remaining mechanical path to find hidden flex, changing optical alignment and shared thermal causes before spending on finer feedback.
