Abstract: An image is printed with an inkjet-printing device using specialty ink (300). The device can use standard cyan ink, standard magenta ink, standard yellow ink, and standard black ink to print full-color images on media. However, the specialty ink is a type of ink other than the types of the standard cyan ink, the standard magenta ink, the standard yellow ink, and the standard black ink. A replacement color ordinarily printed using the standard cyan ink, the standard magenta ink, the standard yellow ink, and/or the standard black ink is determined (306). An image having one or more pixels having the replacement color is printed on the media (316). The pixels that have the replacement color are printed using the specialty ink instead of using the standard cyan ink, the standard magenta ink, the standard yellow ink, and/or the standard black ink.

Abstract: Systems and methods for determining amount of solid ammonia stored in a canister used in providing ammonia fluid in exhaust gas after-treatment systems. A microcontroller sets an ammonia level based on the data read from an RFID tag associated with the canister. The data may provide the amount of solid ammonia stored in the canister or a tag number that the microcontroller may use to retrieve the quantity of stored solid ammonia.

At predetermined precisions, the amount of depleted ammonia is subtracted from the set ammonia level to determine the remaining amount of solid ammonia in the canister. This determined amount of may be used to reset the ammonia level and be written onto the RFID tag.

Abstract: Electrochemical impedance may be used for accurate and real-time tracking and control of fluid delivery from fluid-filled chambers, such as from drug delivery devices. At least two measurement electrodes may be placed within the chamber in contact with the fluid to be sensed. Application of a small alternating current using these electrodes through the fluid/drug may allow measurement of electrochemical impedance. Volumetric changes of the compressible chamber due to movement of at least one surface within the compressible chamber (such as an actuating bellows or flexible diaphragm), may induce changes in the measured electrochemical impedance. Measuring these changes may allow for tracking of ejected liquid volumes from the compressible chamber. By taking the time-derivative of this signal, the rate of volume change can be tracked and therefore the rate of ejected fluid (flow rate) can be deduced.
