An automated coordinate measuring system comprising a measuring arm used for acquisition of geometry data that incorporates an exoskeletal structure resilient to physical perturbations including thermal changes and vibrations which may affect coordinate data acquisition. The alignment of liquid crystal layer LQ is also controlled by circuit array and counter substrates AR and CT. One embodiment of the drug delivery device includes an osmotic engine internal to the device for creating fluid flow through the device. The first dielectric layer is disposed on a surface of the substrate.
