Patent ID: 8011247

Claim:
A micro-electromechanical systems (MEMS) device comprising: a substrate comprising at least one anchor; a proof mass comprising first and second deceleration extensions extending from said proof mass; a motor drive comb; a motor sense comb; a plurality of suspensions configured to suspend said proof mass over said substrate and between said motor drive comb and said motor sense comb, said suspensions anchored to said substrate; a body attached to said substrate; and at least one first deceleration beam extending from a first side of said body, said at least one first deceleration beam configured to engage at least one of said first and second deceleration extensions and slow or stop said proof mass before said proof mass contacts said motor drive comb and said motor sense comb; and at least one second deceleration beam extending from a second side of said body, said at least one second deceleration beam configured to engage at least one deceleration extension extending from at least one crossbeam and slow or stop said proof mass before said proof mass contacts said motor drive comb and said motor sense comb.
