Abstract: According to an example, printing on a media web may include outputting a first instruction to print a first frame on the media web. A first encoder count of an encoder may be determined between a first alignment mark and an end of frame for the first frame. Additionally, a second encoder count of the encoder may be determined between the first alignment mark for the first frame and a second alignment mark for a second frame. A difference value may then be calculated between the first encoder count and the second encoder count. Based on the difference value, a scaling factor of the encoder may be determined. Accordingly, another instruction may be output to print another frame on the media web based on the scaling factor.

Abstract: An image forming system includes a substrate transport unit, an image forming module, an event sensing module, a heartbeat generation module, a signal detection module, and a repositioning module. The substrate transport unit may transport substrate including at least one splice along a transport path. The image forming module may form an image on the substrate. The event sensing module may detect an event and provide an event signal along a signal path in response to the event. The heartbeat generation module may provide a heartbeat signal different than the event signal along the signal path. The signal detection module may determine a presence of the event signal and an absence of the heartbeat signal. The repositioning module may move the image forming module from a first position to a second position in response to a determination of the presence of the event signal.

Abstract: An integrated fuel system unit (10) comprises a two-stage fuel pump (16) and fuel filter (34). The fuel filter is interposed between the first and second pump stages (S1,S2) so fuel flowing between the stages is drawn through the filter. A spiral-wound fuel line (44) delivers fuel from a fuel inlet (18) to the first pump stage. Water is circulated about the fuel line to cool the fuel flowing therethrough. A fuel pressure regulator (60) in an outlet (20) of the unit diverts fuel from the engine back to a cavity (36) in which the filter is housed if an overpressure condition occurs. This fuel is then mixed with the fuel flowing between pump stages. Water also collects in the cavity and a solenoid (74) controlled water passage (72) allows this water to be entrained with fuel flowing to the second pump stage for the water and fuel to be mixed together and pumped to an internal combustion engine to be combusted therein.

Abstract: In a calculating device, a method to allow a user to enter fractions in the form "b/c", where "b" and "c" are integers; "b/c" is a fraction; and the denominator "c" is within a prespecified range. The method to enter real number fractions includes activating one or more digit keys and the successive pressing of a primary function key to distinguish the previously entered numerator value from a subsequently entered denominator value.
