  • Publication number: 20250009566
    Abstract: A customized external cranioplasty includes a rigid section and a rim at least one of attached to or integral with the rigid section and extending at least partially around a periphery of the rigid section. The rigid section has a size and shape to substantially match a cranial defect and includes an impact-resistant material to provide protection and support to a user due to the cranial defect. The rim facilitates secure and comfortable contact of the customized external cranioplasty to the user's head. A method of producing a customized external cranioplasty includes receiving three-dimensional imaging data for at least a portion of a subject's skull that has a cranial defect: segmenting the cranial defect region from a surrounding portion of the subject's skull to obtain a surface requiring support by the customized external cranioplasty; and producing a rigid section of the customized external cranioplasty using said surface requiring support obtained from the segmenting.

  • Patent number: 11629594
    Abstract: A cutting head for a mining machine includes a drum, a vane, and a cutting bit assembly positioned adjacent a surface of the vane. The drum includes a first end, a second end, and an outer surface, and the drum is rotatable about a drum axis. The vane is coupled to the outer surface of the drum and protrudes radially away from the drum axis. In some aspects, the vane includes a planar member extending at least partially around the drum axis and at least partially between the first end of the drum and the second end of the drum. In some aspects, the drum includes a plurality of planar walls extending between the first end and the second end.

  • Patent number: 7899805
    Abstract: Computer-readable media, systems, and methods for augmenting URL queries are described. In embodiments, a URL query is received from a user and it is determined whether the URL query is a simple URL query. Further, if the URL query is a simple URL query, an augmented query is created by word-breaking at least a portion of the URL query and the augmented query is associated with one or more ranking preferences. In various other embodiments, a URL query is received from a user and it is determined whether the URL query is a complex URL query. Further, if the URL query is a complex URL query, an augmented query is created that is identical to the URL query and the augmented query is associated with one or more ranking preferences.

  • Publication number: 20050132744
    Abstract: A flat-tube evaporator and a refrigeration system including a flat-tube evaporator. The flat-tube evaporator can include an inlet manifold, an outlet manifold separated a distance from the inlet manifold, a distributor tube positioned within the inlet manifold and fluidly connected to the common distributor, and a plurality of flat tubes positioned to fluidly connect the inlet manifold and the outlet manifold. The distributor tube can include a plurality of orifices, each of the plurality of orifices positioned to direct the refrigerant into the inlet manifold in a first direction. Each of the plurality of flat tubes can be positioned to direct the refrigerant from the inlet manifold to the outlet manifold in a second direction, the second direction being substantially opposite the first direction.
