Transducer

A multi-directional transducer comprising at least two transducers, each said transducer comprising:

• a deflectable seismic mass supported on a frame by support structure, said seismic mass having a surface, a plane of said surface being disposed in a first orientation when said seismic mass is disposed in a rest position, wherein the support structure comprises a plurality of parallel beams each extending at an angle .alpha. relative to said plane of said surface whereby when the seismic mass is deflected by a force, irrespective of a direction of the force, the plane of said surface will be disposed in an orientation substantially parallel to said first orientation,
• wherein the seismic mass of each said transducer deflects along a single axis, and
• wherein the transducers are arranged such that said axes of deflection are not parallel to one another.

A single axis accelerometer including a force transducer comprising:

• a deflectable seismic mass supported on a frame by support structure, said seismic mass having a surface, a plane of said surface being disposed in a first orientation when said seismic mass is disposed in a rest position, wherein the support structure comprises a plurality of parallel beams each extending at an angle .alpha. relative to said plane of said surface whereby when the seismic mass is deflected by a force, irrespective of a direction of the force, the plane of said surface will be disposed in an orientation substantially parallel to said first orientation.

A three dimensional accelerometer including three force transducers each comprising:

• a deflect able seismic mass supported on a frame by support structure, said seismic mass having a surface, a plane of said surface being disposed in a first orientation when said seismic mass is disposed in a rest position, wherein the support structure comprises a plurality of parallel beams each extending at an angle .alpha. relative to said plane of said surface whereby when the seismic mass is deflected by a force, irrespective of a direction of the force, the plane of said surface will be disposed in an orientation substantially parallel to said first orientation.
