The results of the query are displayed on two regions of the user's screen. On a first region of the user's display screen a list of information relating to the plurality of retrieved web sites is displayed. On a second region of said display screen, information from said at least one content module associated with the query is displayed.

Abstract: A medical chair provides a radiolucent backrest pivotally secured to a seat section. A pivoting push bar on the backrest pivots between an operative position, where it can be used to maneuver the chair, and a storage position where it does not compromise the radiolucent property of the backrest. The chair includes a leg support section, and the backrest and leg support section pivot between a chair structure and a stretcher structure. The pivoting of the backrest and legs support section are controlled by actuators that are positioned so as not to interfere with the radiolucent property of the backrest. A foot platform on the leg support section is connected to remain substantially parallel to the seat section as the leg support section is pivoted. A remote control allows for adjusting the configuration of the chair from points distant from the medical chair.

Abstract: A mobile patient stretcher is provided and particularly adapted for additional use as a pain clinic treatment table designed to accommodate a C-arm of a fluoroscopic or like imaging apparatus. The stretcher litter top or patient support surface is radiolucent and includes selectively removable lateral side rail sections so that the litter top can be selectively converted into an hourglass shape without side rails as required for treatment procedures and/or C-arm access and imaging. On the other hand, with the lateral side rail sections in place, the stretcher includes a full-width patient support surface, and also includes a radiolucent fowler back rest, selectively deployable side rails, and a hydraulically or otherwise controlled conventional wheeled stretcher base that is adapted to place the patient support surface in a raised, lowered, Trendelenburg, or reverse Trendelenburg orientation.

Abstract: The invention disclosed and taught herein teaches method and apparatus for restricting the ingress of hot combustion gases into the turbine disc plenum of a gas turbine engine as the hot gases flow from a turbine nozzle assembly and into the turbine blades. A jet of engine cooling air is injected into the wake region immediately behind and down stream of the nozzle assembly's stator vanes thereby reducing the static pressure recovery otherwise occurring within the wake region. Thus, a lessor amount of buffering air is required within the turbine disc plenum to prevent the ingress of hot gases thereby resulting in an increased efficiency of the engine's cooling air delivery system and over all engine performance.
