Abstract: Self calibrating micro-fabricated load cells are disclosed. According to one embodiment, a self calibrating load cell comprises a resonant double ended tuning fork force sensor and a phase locked loop circuit for detection of frequency changes upon external load application to the resonant double ended tuning fork force sensor.

Abstract: In one embodiment, a shape-reconfigurable structure includes a rigid base having first and second ends, a rigid first beam having a lateral end and a central end, the lateral end being connected to the first end of the base, and a rigid second beam having a lateral end and a central end, the lateral end of the second beam being connected to the second end of the base and the central end of the second beam being connected to the central end of the first beam, wherein the structure can be placed in an expanded orientation in which the first and second beams extend outward away from the base and a contracted orientation in which the first and second beams extend inward toward the base.

Abstract: Seismic protection materials are derived from assemblages of unit cells, where each of the cells has a core, one or more shells disposed about the core, and rigid plates bounding the shells. The cores limit relative vertical movement between the plates, and the shell(s) limit relative lateral motion between the plates. Uncompressed cores are preferably substantially spherical or cylindrical, and can be solid or hollow. Unit cells can be aligned in same or different directions, both within a given layer of cells, and in different layers of cells. Assemblages can have any suitable overall shape and size, depending upon application, and for example can support objects ranging from table top equipment to large buildings and bridges.
