Abstract: An atmospheric moisture harvesting system, in which water vapor is separated from the air using a liquid desiccant subsystem. The moisture charged liquid desiccant enters a desorber and condensation system, where the moisture is extracted. Cooling and condensation are performed on the extracted water vapor only, thereby saving the energy for cooling air containing the water vapor, as is done in direct cooling systems. The system thus operates as a single stage vapor separation system since the vapor concentration remains in the liquid desiccant which is circulated to the separation and condensation subsystems without air laden with the moisture. Low grade or solar heat can be used as the energy source for the vapor desorption. A heat exchanger utilizes unwanted heat from regenerated desiccant to heat up charged desiccant entering the regenerating stage. The system has substantial energy savings over prior art systems using direct cooling of air.

Abstract: Single bulk unimorph piezoelectric elements, with interdigitated electrodes aligned obliquely relative to the direction perpendicular to the axis of the element, such that a torsional response is induced into the element. When such elements are used as a beam structure, with angularly oriented electrodes on both opposite surfaces of the beam, and with their orientations at mutually opposite angles, motion ranging from pure torsional rotation to pure bending can be obtained, depending on the comparative level and polarity of the voltages applied to each of the two electrode sets. If such elements are used as the spiral support arms of a central platform, a large displacement of the stage can be achieved. Due to the oblique orientation of the IDE's, the piezoelectric transduction induces torsional deformation in the spirals, and this torsion is converted by the spiral arms to a parallel out-of-plane platform motion.
