  • Publication number: 20240125546
    Abstract: The present invention is directed to a method, device and system to efficiently liquefy and isolate a gas from a gaseous mixture. In an embodiment of the present invention, separation of gasses from the atmosphere can be carried out using a cooled surface to separate the gasses from the atmosphere. In an alternative embodiment of the present invention, removal of CO2 from the atmosphere can be carried out by using the method, device and system to efficiently cryogenically separate CO2 from air and capture the CO2 from a gaseous mixture using a surface and release the ‘CO2 lean air’ into the atmosphere and store the captured liquefied CO2.

  • Patent number: 10589466
    Abstract: A system and method are provided for implementing adjustable curing of layers of deposition materials, including ultraviolet (UV) light or photo curable ink layers, used in the formation and/or manufacture of three-dimensional (3D) printed parts, objects and components, particularly those parts, objects and components formed in 3D printers and additive material manufacturing systems such as 3D jetted ink printing systems. A multi-layer (or layer-by-layer) history of the deposited materials is developed by which to adjust an intensity of an addressable curing unit to provide complete curing to a particular layer without introducing damaging effects that may be caused by over curing the particular layer. The applied curing energy will differently penetrate a number of layers based on constitutions and/or colors of the individual layers in the number of layers to be penetrated. Discrete addressable curing of the individual layered components provides correct curing to the individual layers.

  • Patent number: 10160194
    Abstract: A system and method are provided for implementing a comparatively higher speed process for surface curing of finished three-dimensional (3D) printed parts, objects and/or components, formed and/or otherwise manufactured in 3D printing systems and/or in additive material manufacturing processes. A vacuum finish curing chamber is provided within, or associated with one or more 3D printers to provide a locally-generated substantially oxygen depleted curing environment to support effective and efficient surface curing of one or more formed 3D printed parts. The vacuum finish curing system includes at least one device for emitting curing radiation and at least one object transport system for transporting formed 3D objects to the vacuum finish curing chamber without requiring user handling that would be hazardous to handling individuals.

  • Patent number: 6978441
    Abstract: A method of rating a bug, including reporting the bug to a business entity by an interested party, entering information regarding the bug into a database, assigning a priority number for the bug, calculating a sigma number for the bug using the priority number, evaluating the bug to be fixed using the sigma number, and escalating the bug. A bug council rating apparatus, including a database to store the information entered using a graphical user interface, a priority number module configured to generate a priority number, and a sigma number module configured to generate a sigma number.

  • Publication number: 20030177417
    Abstract: A server has a memory and an analyzer. The memory stores a library of symptom descriptions, a library of corresponding diagnoses, a library of corresponding remedies, and a library of corresponding probes. The analyzer is coupled to the memory and has an identifier, a comparator, and a reiterater. The identifier identifies at least one symptom of an application to be probed based on an input. That input can either be a user input describing the symptoms of the application or symptoms previously already identified. The comparator compares the symptoms of the application with the library of symptom descriptions. The reiterator reiteravely operates the identifier on the comparator until the symptoms correspond with a diagnosis from the library of corresponding diagnoses.
