Abstract: A build plate assembly for a three-dimensional printer includes: a lighting panel having individually addressable pixels configured to selectively emit light and/or transmit light from illumination below the pixels to a top surface top surface of the lighting panel; a rigid, optically transparent, gas-impermeable planar screen or base having an upper surface having an uneven surface topology and a lower surface that is affixed to the top surface of the lighting panel; and a flexible, optically transparent, gas-permeable sheet having upper and lower surfaces, the upper surface comprising a build surface for forming a three-dimensional object, the sheet lower surface positioned opposite the base, wherein the build plate is configured to permit gas flow to the build surface.

Abstract: A computer system and method for obtaining electronic signatures is disclosed for paperless processing of electronic employment documents, and for automating employment authorization verification. After substantial completion of the fillable fields of an electronic document by a user, the system displays an affirmation screen with affirmation language necessary to meet a statutory requirement for a valid electronic signature and an interface element affirming such language. Only after the interface element has been actuated is a file containing the completed fillable fields marked with an indication that the file has been electronically signed. The employment eligibility verification aspects disclosed utilize a database and server architecture to receive information provided on an electronic employment eligibility form and to perform computerized employment eligibility verification queries with the Federal Government.
