Claim 1
Independent Claim
156 words
A capacitive accelerometer comprising a first substrate, a second substrate having a metallization thereon defining a fixed capacitor plate, a conductive metal disc, a pair of conductive epoxy supports secured to central portions of the metal disc at respective opposite disc sides securing the disc to respective substrates to disposed the disc in selected spaced relation to the substrates and the fixed capacitor plate to mount a disc rim for movement relative to the fixed capacitor plate in response to acceleration, sealing ring means secured to the substrates around the disc rim for sealing the accelerometer, and electronic means connected to the fixed capacitor plate and to a conductive epoxy support so that the disc rim and plate form a capacitor, the disc rim moves in response to acceleration to provide a change in capacitance of the capacitor corresponding to the acceleration, and the electronic means provide an output signal corresponding to the change of capacitance.

Claim 3
Dependent Claim
35 words
An accelerometer according to claim 1 wherein the central portion of the disc is connected to the disc rim by a plurality of arms extending from the central disc portion in a plurality of directions.
Claim 4
Dependent Claim
23 words
An accelerometer according to claim 1 having three arms spaced around the periphery of the central disc portion connected to the disc rim.
Claim 5
Dependent Claim
143 words
A capacitive accelerometer unit comprising a mass formed of a sintered metal powder, a support of sintered metal powder surrounding the mass, a plurality of integral tabs interconnecting the mass and support to be substantially coplanar, and a spring metal beam secured to the mass and support ring by low-stress attachment means selected from the group consisting of solders, brazing materials, welds and adhesives to retain the mass substantially coplanar to be response to acceleration to move relative to the support, whereby the support is adapted to be secured in selected spaced relation to a fixed capacitor plate and to have the tabs removed to disposed the mass in selected spaced relation to the plate to form a capacitor and to permit movement of the mass in response to acceleration to produce a change in capacitance of the capacitor corresponding to the acceleration.
