Abstract: Various examples are directed to systems and methods for generating improved autonomous vehicle (AV) navigation route data and estimated time of arrival (ETA) data. A system may receive delivery data from an AV delivering a passenger or product, where the delivery data includes a delivery origin, a delivery destination, and an ETA and navigation route generated by the AV. The AV may have accurate short-term information, such as the next few navigation maneuvers planned by the AV. The system may be able to provide more accurate longer-term information, such as generating an overall calculated route and calculated completion time based a current location and the delivery destination. The system may receive updated short-term information and combine this information with the calculated route and calculated completion to generate a more accurate set of route data and ETA data.

Abstract: The present invention introduces a capillary distillation method comprising the following steps: heating wastewater, subsequently directing the heated wastewater to one end of a water-diversion fiber material. Through capillary action, the heated wastewater permeates the water-diversion fiber material, diffusing downward along microchannel pathways within the material. Upon reaching the surface of the water-diversion fiber material, the wastewater evaporates. Water vapor is then directed to a condensation module, where it undergoes condensation and collection, resulting in the production of fresh water.

Abstract: Multi-state switchability is highly desirable in optoelectronic devices. For liquid crystal (LC) based devices, the stability of any configuration is achieved through a balance between imposed interactions and the LC's orientational elasticity. In most cases, the latter acts to resist deformation. By combining surface topography and chemical patterning, provided here are the effects of saddle-splay orientational elasticity, a property that, despite being intrinsic to all LCs, is routinely suppressed. Utilizing theory and continuum elastic calculations, provided here are example conditions for which, even using generic, achiral LC materials, spontaneously broken surface symmetries develop. Also provided are multi-stable devices in which a weak, but directional, applied field switches between spontaneously-polar surface state domains. The disclosed approach is useful in low-field and fast-switching optoelectronic devices, beyond those attainable by current technologies.
