Abstract: Systems and methods are described for merging customer profiles, such as may be implemented by a computer-implemented contact center service. In some aspects, a subset of profiles may be determined that satisfy merging criteria, where individual profiles include a plurality of data fields. At least one value in a first data field that conflicts between at least two profiles may be identified. Next a merged value may be selected for the first data field based on data deduplication criteria, where the data deduplication criteria includes at least one indicator of accuracy of values of the plurality of data fields. As a result of a determination that at least the subset of profiles of the group of profiles meet the merging criteria, at least the subset of profiles may be combined into a combined profile using the merged value.

Abstract: The present disclosure relates to a tensioning system for use in a stereolithography manufacturing application. The system may have a build plate for supporting a three dimensional part being formed using a photo responsive resin, a base plate and a release element extending over the base plate. The release element is configured to receive a quantity of photo responsive resin for forming a new material layer of the three dimensional part. A pair of tensioning components are secured to opposite ends of the release element, and apply a controlled tension force to the release element during peeling of the release element to reduce a separation force required to separate the release element from the new material layer after the new material layer is cured.

Abstract: The present disclosure relates to a liquid crystal display (LCD) system. The system in one example has a light source for generating unpolarized light, and an LCD screen arranged in a path of transmittance of the unpolarized light. First and second wire grid polarizers are arranged adjacent to the LCD screen and each have a plurality of nano-scale wires, with the first and second wire grid polarizers have differing polarizations. A pitch of each of the nano-scale wires is no larger than one-third a wavelength of the unpolarized light from the light source. The wire grid polarizers create, in connection with operation of the LCD screen, a 2D light mask suitable for initiating the polymerization of an optically curable material.

Abstract: An atomizer having an antifouling structure and an electronic cigarette having the same are disclosed. The atomizer includes a device housing and an atomizing unit disposed inside the device housing. The device housing defines therein a liquid storage chamber configured for storing tobacco liquid. The atomizing unit is configured for atomizing the tobacco liquid to produce an aerosol. The device housing further includes an aerosol channel in communication with the atomizing unit and is configured for expelling the aerosol. The antifouling structure mainly includes a hydrophobic oleophobic surface or super oleophobic surface formed on an inner wall of a member forming the aerosol channel or the liquid storage chamber. The antifouling structure prevents condensed droplets from accumulating and adhering to the inner wall of the aerosol channel or the liquid storage chamber, thereby avoiding users inhaling the condensed droplets into their mouths when smoking next time.
