Abstract

A night vision goggle adapter including: a goggle mount assembly; a primary magnet generating a magnetic flux; a magnetic flux conducting unit having a first end and a second end; a first plurality of shunts; and a second plurality of shunts disposed about the goggle mount assembly; wherein the magnetic flux conducting unit may overlap the primary magnet and form a magnetic circuit for conducting the magnetic flux towards the second end of the magnetic flux conducting unit when none of the first plurality of shunts and none of the second plurality of shunts are overlapped by the magnetic flux conducting unit; and wherein the magnetic flux is shorted through one of the first plurality of shunts or the second plurality of shunts when the magnetic flux conducting unit is positioned to overlap one of the first plurality of shunts or one of the second plurality of shunts.

Dependent claims

A flux switching helmet mount assembly, comprising:

a mounting base comprising:
a central axis;
a booster magnet positioned about the central axis and having a first polar orientation;
and
a suppressor magnet positioned about the central axis and displaced from the booster magnet and having a second polar orientation;
a magnetic flux conducting rail assembly;
and
a mounting point coupled to the mounting base;
wherein the magnetic flux conducting rail assembly is configured to be rotatably coupled to the central axis and is further configured to overlap the booster magnet in a first position and conduct a magnetic flux according to the first polar orientation along the magnetic flux conducting rail assembly;
and
wherein the magnetic flux conducting rail assembly is configured to overlap the suppressor magnet in a second position and conduct a magnetic flux according to the second polar orientation along the magnetic flux conducting rail assembly.
