Abstract:
A multisensor, comprising, in combination:a) a substantially planar mounting base having a floor;b) an upper and a lower rotor, including a central rotor hub having a bore therethrough and at least one radially-directed arm fixed to said hub and having a distal end;c) said rotors being aligned along a common central axis;d) an accelerometer fixed adjacent to said distal end of each said arm;e) means coupled to each said rotor for rotationally oscillating said rotor about said common central axis, said rotors being arranged to counter-oscillate with respect to one another about said axis;f) said means for oscillating each said rotor including at least one radially-directed planar spring fixed to said hub of said rotor, each said spring having a distal end;g) means for inducing flexure of said spring in response to an electrical signal;h) a ring fixed to said distal ends of said radially-directed springs; andg) means for coupling said means for oscillating said rotors to said mounting base.
