  • Publication number: 20240122555
    Abstract: A framework for troubleshooting medical imaging equipment. Log event data and state data of one or more components of the medical imaging equipment are received. One or more calculations are performed based on the log event data and state data to generate processed data. One or more representations of the one or more components of the medical imaging equipment may then be generated based on the processed data, the log event data, the state data, or a combination thereof.

  • Patent number: 11951683
    Abstract: A method for improving z-axis strength of a 3D printed object is disclosed. For example, the method includes printing a three-dimensional (3D) object with a polymer and magnetic particles, heating the 3D object to a temperature at approximately a melting temperature of the polymer, and applying a magnetic field to the 3D object to locally move the magnetic particles in the polymer to generate heat and fuse the polymer around the magnetic particles to improve a z-axis strength of the 3D object.

  • Publication number: 20070246193
    Abstract: The invention provides a heat exchanger assembly for cooling an electronic device wherein the upper portion of the housing includes a plurality of condensing tubes extending upwardly from the lower portion of the housing. A plurality of air heat transfer fins zigzag transversely to a primary axis (A) between adjacent ones of the condensing tubes for dissipating heat from vapor boiled off of the refrigerant. At least two next adjacent condensing tubes of the plurality diverge upwardly from the bottom ends toward the top distal ends thereof. Accordingly, the space containing the air heat transfer fins between the two next adjacent condensing tubes is greater at the top distal ends than at the bottom ends of the condensing tubes. The condensing tubes can either have a constant cross-section with diverging tube axes or can have a decreasing cross-section from bottom to top with parallel tube axes.

  • Publication number: 20070141485
    Abstract: This invention relates to a method of coating multiple layers on a support comprising a) taking a support; b) simultaneously coating on said support a chill settable layer and a non-chill settable layer; c) lowering the temperature of the layers to immobilize said layers; and d) drying said layers. It further relates to imaging elements made by this process.

  • Patent number: 7201110
    Abstract: A portable hatch-mounted fan that is removably mounted to an existing hatch of a boat or a recreational vehicle by a pair of fast action spring-type vertically adjustable clamps, which adjust to fit various hatch frame thicknesses. The clamps, clamp guide plates and guides are also horizontally adjustable on the fan frame to fit various sizes of hatch openings.

  • Publication number: 20060065389
    Abstract: The subject invention provides a heat transfer device (24) for controlling the temperature of an instrument panel (18) extending from and under a windshield (16) of a vehicle (10). Sunlight (22) passes through the windshield (16), thereby heating the surface of the instrument panel (18). The instrument panel (18) then transfers the heat to an interior compartment (14) of the vehicle (10) affecting the thermal comfort of a passenger. The heat transfer device (24) directly removes the heat stored in the instrument panel (18) to limit the transfer of heat from the instrument panel (18) to the interior compartment (14). Preferably, the heat transfer device (24) circulates a flow of cooling air (40) over the surface of the instrument panel (18) to remove the heat stored therein. As such, the heat transfer device (24) limits the heat transfer into and thereby cools the interior compartment (14) of the vehicle (10) to meet the desired thermal comfort level of the passenger in less time and with less energy.

  • Patent number: 4828709
    Abstract: A recirculating shower is especially adapted for showering a person's body with a relatively small supply of water. Before it is directed into the shower stall, the water is first recirculated through an alternate series loop pathway and concurrently cleaned and filtered as well as being heated to a desired temperature level. During the showering of the person's body the water continues to be recirculated, cleaned, filtered, and heated. When the showering is completed, the water is again directed through the alternate pathway for further cleaning and filtering, in preparation for a subsequent re-usage.
