Abstract: An apparatus and method for forming a film hole in an outer wall of an airfoil. The film hole includes a blind opening adjacent the interior of the airfoil and a hole adjacent the exterior of the airfoil. The blind opening fluidly couples to the hole to form the film hole for providing a volume of fluid as a surface cooling film along the exterior of the outer wall.

Abstract: A weldless thru wall fitting that provides a leak free connection to a vessel that can easily be installed and removed. The fitting also provides an integrated, removable, and repositionable dip tube to allow the liquid stored in the vessel to the drained via gravity to a level below the entry point of the fitting.

Abstract: An engine component assembly includes a first engine component having a hot surface in thermal communication with a hot combustion gas flow and a cooling surface, and a second engine component having a first surface in fluid communication with a cooling fluid flow and a second surface spaced from the cooling surface to define a space. A cooling aperture extends through the second engine component. A cooling feature extends from the cooling surface of the first engine component, and is oriented relative to the cooling aperture such that the cooling fluid flow is orthogonal and non-orthogonal to different portions of the cooling feature.

Abstract: A component for a gas turbine engine comprises an airfoil having an outer surface. One or more cooling passages can be disposed within the airfoil, having a cooling passage extending along a trailing edge. A plurality of cooling channels can extend from the cooling passage through the trailing edge. At least one flow element and at least one film hole can be disposed in the cooling channel or the trailing edge passage adjacent the cooling channel. The flow element and the film hole can be in a predetermined relationship with one another providing improved flow to the film hole.

Abstract: Systems, methods, and non-transitory computer-readable media can determine a predicted bandwidth value for communications between a first computing system and a second computing system associated with a user of the first computing system. The first computing system can categorize the predicted bandwidth value into a connection quality class of a plurality of connection quality classes. The first computing system can customize provision of information from the first computing system to the second computing system based on the connection quality class.

Abstract: A single system may provide to a patient: temperature change, remote ischemic conditioning, and sometimes both concurrently. The system may include a patient unit that includes an inflatable bladder, and a duct having a cavity. The patient unit is intended to be applied around a patient's limb. A temperature subsystem can force a flow of a first fluid through the cavity so that the first fluid can exchange heat with the patient's limb. The pressure subsystem may force a fluid into the bladder, to establish pressure against the limb. A controller may control both the temperature subsystem and the pressure subsystem, so as to control the treatment received by the patient.

Abstract: The invention is an oral appliance for prevention of sleeping problems including snoring, sleep apnea and bruxism, and may also be used to protect the teeth and gums from surgical instruments during surgery. Specifically, the appliance alters the position of the user's mandible, which is known as a method for reducing the restriction of the flow of air through the pharyngeal passageway. The appliance is a one-piece device molded from a flexible polymer. It includes an upper maxillary tray and a lower mandibulary tray. Both upper and lower trays include inner and outer walls which increase contact area with the teeth. The hinge mechanism of the device includes a positive positioning system comprised of opposed interlocking ridges. The ridges serve to create offset between the position of the upper tray and lower tray relative to each other, therefore advancing the user's mandible.

Abstract: A process challenge device tailored to mimic the resistance of a particular product to a particular biological inactivation, disinfection, or sterilization process, and used to challenge the process, thus providing a means to validate the efficacy of the process. The process challenge device is used by subjecting the device containing indicator organisms to an inactivation or sterilization process, and culturing any surviving indicator organisms as a means to assess the efficacy of procedures for the inactivation of microorganisms. The device uses a self-containing biological indicator (SCBI) with a biological indicator and media ampule located within a plastic vial. By altering the materials and/or configuration of the SCBI a wide range of resistances to sterilant gas processes may be achieved.

Specifically, the appliance alters the position of the user's mandible, which is known as a method for reducing the restriction of the flow of air through the pharyngeal passageway. The appliance is a one-piece device molded from a flexible polymer such as Kraton®. It includes an upper maxillary tray and a lower mandibulary tray. Both upper and lower trays include inner and outer walls which increase contact area with the teeth. The hinge mechanism of the device includes a positive positioning system comprised of opposed interlocking ridges. The ridges serve to create offset between the position of the upper tray and lower tray relative to each other, therefore advancing the user's mandible. Additional features include airflow posts to keep the mouthpiece from sealing completely, a cleft contour, and a tooth retention tab.

Abstract: A feline teething and teeth cleaning toy in which the combination of elements functions as a natural complete dental care device in a manner consistent with that of a toothbrush and dental floss while assisting the natural digestive process of cats. The combination of elements, a bone ring wound with natural hemp, natural feather(s) and natural dried catnip leaves utilizes a cat's natural instincts to promote its overall effectiveness. As cats instinctively enjoy playing with the toy, the chewing of the ring and hemp gently brushes and scraps the teeth and stimulates the gums. The chewing and pulling of the extended feather(s) and hemp through the teeth flosses the teeth and the consumption of the natural dried catnip leaves assists the cat's natural digestive process.

Abstract: A process challenge device tailored to mimic the resistance of a particular product-package combination to a particular biological inactivation, disinfection, or sterilization process. The device is used to challenge the process, thus providing a means to validate the efficacy of the process. In one embodiment, the process indicator includes a biological indicator organism stored on a carrier enclosed within a chamber formed by a barrier film material. The specific indicator organism and carrier substrate are chosen for their appropriateness for a given process. The materials comprising the barrier film material of the process challenge device are chosen for the materials' specific resistance to the given process. The process challenge device may also comprise a separate second chamber filled with an appropriate culture medium or enzyme substrate that is separated from the chamber containing the process indicator by a separation means, such as a valve, a clip, or a frangible separation.

Abstract: An offset butterfly valve with a valve body, air flow conduit extending there through, and an offset rotatably mounted valve plate. The air flow conduit has with no interruptions to impede air flow there through. Cross sections along any location of the conduit are essentially round and of equal diameter while the valve plate is the shape of an oblique cross section of the conduit and rotatably mounted therein. The valve plate axis of rotation is offset with respect to the center of the valve plate and further offset with respect to a center of the conduit. Rotation of the valve plate within the conduit is accomplished by providing two opposing indentations on the interior of the conduit which accommodate the maximum diameter dimension of the valve plate when the valve plate is rotated to an open position. The indentations do not interrupt air flow through the conduit or the sealing of the valve plate periphery which may be easily machined to seal with a sealing surface of the interior of the conduit.
