Abstract
Angular motion sensor for sensing angular velocity components at higher frequencies. A first lower case member open at the top thereof supports a magnet therein for establishing a magnetic field oriented parallel to a central axis of the lower case. An insulating surface covers the magnet and a conductive liquid is disposed in a channel defined by the insulating surface and the lower case sidewalls. An upper case having an insulated inner surface including a sidewall structure complementary to the lower case sidewall structure forms a lid for the channel and is insulated from the lower case. The upper case is insulated from the conductive liquid, except at a hole in the insulation lying along a central axis of the lower case and upper case. Relative motion between the liquid mass and upper and lower case structures generates a voltage potential between the upper and lower cases, representing the relative velocity.
