Patent ID: 7886451

Claim:
An electrolytic tilt sensor which comprises: a) a containment envelope defining an interior space, said containment envelope comprising a tubular member extending between first and second annular ends and defining a longitudinal direction therebetween, said interior space being arcuately configured in the longitudinal direction between said first and second annular ends; b) at least first and second electrodes disposed along, and in contact with, a curved first interior surface portion of the containment envelope, said first interior surface portion being concave in the longitudinal direction, and said first and second electrodes being longitudinally spaced apart from each other to define a gap between respective opposing edges of the first and second electrodes; c) at least a third electrode disposed along and in contact with a curved second interior surface portion of the containment envelope opposite said first interior surface portion, said second interior surface portion being convex in the longitudinal direction; d) an electrolyte solution at least partially filling the interior space of the containment envelope to provide a bubble; wherein said containment envelope is hermetically sealed.
