Abstract: Weave is a process for fabrication of freeform shells, proceeding from a formal definition of desired final shape(s), to an optimized parametric mesh of said shape(s), to physical battens which, once fastened at calculated crossings, realize the final object of use. This initially iso-parametric mesh is triangulated for self-shaping and rigidity, and optionally spiralized for economy, integrity of raw material, and surface smoothness The mesh's density and topology is controlled by Weave such that the constructed object automatically takes on, as it is fastened, the shape and dimensions of the designed fabrication without explicit registration, alignment or ambiguity. Essential is the precise adjustment of batten length between intersections to accomodate interweaving. Weave's calculations also accomodate all other necessary geometrical and material factors. Weave does not constrain shape type, complexity, scale or material.

Abstract: A measurement operation, such as a calorimetry measurement, is performed using a measurement array and a replaceable passivation membrane (e.g., a parylene membrane). The passivation membrane is used to cover the measurement array to provide temporary electrical and chemical passivation, while still allowing measurement of the parameter of interest (e.g., temperature, in a calorimetry measurement). By only replacing the membrane instead of the entire measurement array between measurement operations, the cost of the measurements can be significantly reduced over conventional methods. The passivation membrane can be mounted on a frame to simplify handling of the membrane.
