Abstract: A method analyzes image data of a test pattern printed on an image receiving member by a printer to identify split inkjets in the printheads of the printer. The test pattern is formed by operating each inkjet of a printhead to form a dash and the areas of the dashes are compared to an average dash area to identify split inkjets. Firing signal parameters for the split inkjets are adjusted and subsequent firing signals are generated using the adjusted parameters. Image data of the pixels formed by the split inkjets are analyzed after the split inkjets have been operated using the adjusted firing signal parameters. If the pixel size for a split inkjets indicates that the split inkjet has been remediated, then the firing signal parameters are returned to their nominal values.

Abstract: A three-dimensional (3D) metal object manufacturing apparatus is equipped with two solid metal moving mechanisms that are independently operated to move two different metals into the receptacle of a vessel in a melted metal drop ejecting apparatus. The ejector is operated to form object features with melted metal drops of one of the two different metals and to form support features with melted metal drops of the other of the two different metals. The thermal expansion coefficients of the two metals are sufficiently different that the support features easily separate from the object features after the object and support features cool.

Abstract: A personalized packaging production system includes an in-feed tray, an out-feed tray, a cutting table disposed intermediate the in-feed tray and the out-feed tray and an interchangeable cutting/creasing assembly. A sheet feeder is positioned between the in-feed tray and the cutting table to feed media sheets from the in-feed tray to the cutting table, and an exit nip is positioned between the out-feed tray and the cutting table to remove media sheets from the cutting table to the out-feed tray.

Abstract: Methods and systems for preventing collisions between vehicles and moving hazards include the use of active signs, a network of sensors, and a controller. Such sensors can be placed adjacent to a roadway and are used to detect the presence of animals. The active signs display a local speed limit. The controller accepts the sensor signals as input and outputs display commands to the active signs. The controller maintains a rolling window of recent detections in histogram form. The recent data, together with a control law specified by the municipal authority, can be used to specify updated local speed limits to influence driver behavior.
