An electronic motion-based input device and method for correcting errors in acceleration due to a deviation from a horizontal plane of motion by correcting for gravitational acceleration components due to the deviation in the plane of motion. The probe includes a hollow, sealant-releasing section, for insertion into the hole in the upper member into at least a portion of the sealant-receiving region. For example, in various embodiments, the cell enclosure includes one or more corrugations descending from the top wall, which, upon contact with the bottom wall, contribute to impact absorption.
