  • Patent number: 11040492
    Abstract: A system (100) and method for monitoring a recoating mechanism (415A, 415B) in an additive manufacturing environment is provided. Various embodiments involve the use of a control computer (102a-102d) to receive data based on a thermal image of a recoating mechanism (415A, 415B) from an imaging device (436) configured to capture thermal image. The control computer (102a-102d) further determines a value of a property of the thermal image, wherein the property is related to an amount of powder in the recoating mechanism. The control computer (102a-102d) further determines at least one of if the value indicates an error related to the amount of powder in the recoating mechanism (415A, 415B), and an action to take with respect to the recoating mechanism (415A, 415B) that is based on the value.

  • Patent number: 10846921
    Abstract: A method and system for archiving 3D geometry information for a plurality of subjects, and on a particular part of the body (which may also be the whole body) is described. The method and system allow an organizing and an analyzing step, resulting in scalable characteristic components for the particular part of the body, and an approximation of the geometry of that particular part of the body for a specific subject by a combination of a subset of those characteristic components with corresponding scale factors, which are then stored.

  • Patent number: 7238647
    Abstract: The present invention relates to a method and to a fluid for drilling or workover in a well running through a porous permeable formation, wherein a water-based well fluid circulates in said well. In the method, at most 3% by weight of a composition obtained from fat, or an oil, and an alcohol, is added to the fluid in addition to the conventional constituents for such a fluid, the chain lengths of the acid and alcohol parts being chosen such that the ester thus obtained has sufficient dispersion in water, compatibility with said constituents, does not form an emulsion with the reservoir oil and adsorbs sufficiently on the porous formation.

  • Patent number: 5849356
    Abstract: The invention hereof is a new highway deicing additive and a method for deicing asphalt highways. It has been discovered that a small amount of starch added to the salt/water sprayed on highways provides the unexpected property of retaining salt particles in the top portion of the "voids" in the asphalt roads for a period of 2 to 4 hours. The starch can be incorporated into water by mixing; biocides can be added if the starch/water mixture is to be stored more than 2 days. Salt is added to the water/starch mixture prior to deposition on the road. The new treatment works by increasing the viscosity of the aqueous fluid sprayed on the highway to form a water gel structure on the road providing a "platform" for the salt particles in the top portion of the asphalt. The new additive also reduces the need and cost of "follow-up" salt treatments.The additive and method are particularly useful for the new type of asphalt being used on highways in Europe which has a super-porous structure when laid as a road-bed.
