Abstract: A memory module, a printer assembly, and a method for storing a computer code for a printer-controller application specific integrated circuit (ASIC) having a non-ROM memory control. The memory module has ROM memory cells and a non-ROM to ROM interface operatively connected to the ROM memory cells. The printer assembly has the above-described ASIC, the above-described memory module, and a transmission cable operatively connected to the non-ROM memory control of the ASIC and the non-ROM to ROM interface of the memory module. The method stores non-final versions of the computer code in a memory module having non-ROM memory cells, which allows the code to be changed during development, and stores the final version of the computer code in the above-described memory module having the ROM memory cells.

Abstract: A calibration resistor and a capacitance load are placed in parallel across the output of a voltage source and a first decay time is determined for the voltage to reach a second voltage from a first voltage after the voltage source is disconnected. With the calibration resistor electrically removed, N printheads of a printer and the capacitance load are placed in parallel across the voltage source output. In a first example, the voltage across the capacitance load at a second decay time, which is shorter than the first decay time, is determined and indicates at least one possibly shorted printhead when less than the second voltage. In a second example, the voltage across the capacitance load at the first decay time is determined and indicates at least one possibly shorted printhead when less than a third voltage which is less than the second voltage.

Abstract: A brush seal, which may be used in gas or steam turbine rotor applications, includes a packet of bristles attached to a seal housing. A seal member is slideably-attached to the seal housing, has a planar first surface portion parallel to, and slideably in contact with, a first surface of the seal housing, and has a planar second surface portion which is parallel to, and slideably in contact with, a first side of the bristle packet. A mechanical spring is positioned in compression between the seal housing and the seal member.
