Abstract: Embodiments can provide interactivity to one or more components (e.g., windows, dialog boxes, tool bar, etc.) in a visual analyzer application while blocking interactivity for other components displayed on a GUI of the application. A contribution mechanism can be leveraged where a broadcast message can be sent to various components displayed on the GUI of the application. The various components within the application can then indicate whether they would like to be kept interactive during a triggering event (e.g., upon selection of a certain component). Upon receiving the indication that the components would like to remain interactive, the application allows those components to remain interactive while preventing access to other components in the GUI.

Abstract: An ink-cooled thermal ink jet printhead has an efficient heat exchanger located on the back side of the printhead that eliminates the need for heat sinks. All ink flowing to the firing chamber goes through the heat exchanger. The geometry of the heat exchanger is chosen so that almost all the residual heat absorbed by the printhead substrate is transferred to the ink as it flows to the firing chamber. Additionally, the pressure drop of the ink flowing through the heat exchanger is low enough so that it does not significantly reduce the refill rate of the firing chambers. The heat exchanger can have one or more active heat exchanger sides. The heat exchanger has little thermal mass itself and significantly reduces the thermal mass of printhead by eliminating the need for a heat sink. This reduces the warm-up time of the printhead to a fraction of a second.
