Methods and apparatus enable calibration of a display for a particular user thereof. An image displayed such as by an interactive system is adjusted based on physical attributes associated with the user or other characteristics of the user in order to customize the image being displayed. For some embodiments, change to the image includes dynamically resizing and/or repositioning a projected display based on the size and reach of the user to make items shown in the display such as menus or hyperlinks more easily accessible to the user. Input from a camera of the interactive system can be utilized to detect the attribute such as a height of the user for correlation to a typical reach of the user. In operation, the interactive system can therefore dynamically adapt to each unique user as different users approach and interact with the interactive system by automatic calibration of the image being displayed.

This disclosure generally concerns x-ray device cooling systems and related components. One example of such a component is a coolant pump that includes an casing with a pair of fluid interfaces and an electrical interface. The casing includes a body with first and second ends. A motor is disposed within the casing and includes a shaft to which an impeller is attached. A first end cover is attached to the first end of the casing body, and a second end cover includes an electrical interface and is attached to the second end of the casing. Each of the end covers cooperates with a corresponding sealing element to aid in sealing the casing. One or both of the end covers is removably attached to the body of the casing to permit removal and repair/replacement of components disposed within the casing.

A method for forming a metallic fabric includes forming a composite yarn having a metallic wire core, and a cover yarn including a fluid-soluble strand such as co-nylon or polylactic acid. The composite yarn can be knitted into an intermediate fabric product. The soluble element is dissolved to leave a use fabric suitable for other processing, such as coating with materials such as latex. The non-fluid-soluble strand may be either a single strand or multi-filaments of steel wire.

An antimicrobial, cut-resistant composite yarn has a core including at least one cut-resistant strand, and a cover including at least one strand wrapped around and enclosing the core. At least one strand in either the core or the cover is treated with and incorporates an antimicrobial compound. In addition, the yarn can include one or more channel fibers to facilitate movement of moisture within the composite yarn so that the moisture contacts the antimicrobial compound, thereby enhancing the efficacy of the antimicrobial compound. The yarn can be used to fabricate cut-resistant garments, such as gloves, worn by meat cutters and others who work with knives, saws and other sharp implements. The antimicrobial effect reduces bacteria, mold and fungi growth on the garments between washings.

A fluid connection assembly is provided for use with x-ray devices. The fluid connection assembly includes an adapter block configured to be attached about an opening in a housing of an x-ray device. The adapter block defines a fluid port and a cylinder in fluid communication with each other. In addition, the fluid connection assembly includes a flow adapter received in a passageway collectively defined by the cylinder of the adapter block and the opening in the housing wall. The flow adapter defines a fluid passageway configured for communication with the fluid port and the interior of the housing of the x-ray device. A sealing element is interposed between the flow adapter and the housing wall. Finally, a resilient element disposed within the cylinder of the adapter block proximate the flow adapter biases the flow adapter into contact with a shield structure inside the housing.

A graphite-backed metallic x-ray tube target assembly has a rotary shaft which passes through the central opening of the annular graphite substrate and is secured to the metallic disk-shaped target. In order to protect the shaft from heat radiated from the graphite substrate, at least one tubular heat shield is brazed to the target and disposed between and separate from the inner wall of the annular graphite substrate and the outer peripheral surface of the shaft. For further protection, a tubular heat shielding member may be disposed inside the other heat shield, between the outer heat shield and the shaft. In order to minimize the heat conduction from the outer heat shield to the inner heat shielding member, they are mostly separated and attached to each other only along their bottom edges where they are tack-welded together at mutually separated positions such that the inner heat shielding member is supported entirely by the outer heat shield.

An x-ray tube electron shield is disclosed for interposition between an electron emitter and an anode configured to receive the emitted electrons. The electron shield is configured to withstand the elevated levels of heat produced by electrons backscattered from the anode and incident on the electron shield. This in turn equates to a reduced incidence of failure in the electron shield. In one embodiment the electron shield includes a body that defines a bowl-shaped aperture having a narrowed throat segment. The body of the electron shield includes a first body portion, a second body portion, and a disk portion. These portions cooperate to define the bowl and the throat segment. The throat segment and the lower portion of the bowl are composed of a refractory material and correspond with the regions of the electron shield that are impacted by relatively more backscattered electrons from the anode surface.

An integrated fluid pump for use in circulating a coolant in an x-ray tube is disclosed. The pump includes a pump body, a pump head, and a motor. The pump head defines a pump volume and further includes a fluid inlet, a fluid outlet, and an impeller positioned in the pump volume that is rotatably driven by the motor to receive coolant from the fluid inlet and eject the fluid via the fluid outlet. The pump is structurally integrated with an outer housing of the x-ray tube, the outer housing containing the coolant. In one embodiment, the fluid inlet and a portion of the pump volume are defined by a portion of the outer housing of the x-ray tube. This integration makes the structural completeness of the fluid pump dependent on the outer housing or other suitable x-ray tube component.

A shield structure and focal spot control assembly is provided for use in connection with an x-ray device that includes an anode and cathode disposed in a vacuum enclosure in a spaced apart arrangement so that a target surface of the anode is positioned to receive electrons emitted by the cathode. The shield structure is configured to be interposed between the anode and the cathode and includes an interior surface that defines an aperture or other opening through which the electrons are passed from the cathode to the target surface of the anode. Additionally, fluid passageways defined in connection with the shield structure enable cooling of the shield structure. Finally, a magnetic device disposed proximate the cathode facilitates control of the location of the focal spot on the target surface of the anode.
