Abstract
A completely self-contained replaceable cartridge for micro jet dispensing assemblies is thinner than the spacing between a standard 'DIP' socket. Each cartridge body contains a preferably embedded digitally operated micro jet piezoelectric ejector, a tubular capillary reservoir and fixed connecting pins spaced to removably plug into a standard dual in line packaging (DIP) socket strip or board to receive digital ejection signals. A plurality of the individual replaceable cartridges can be closely positioned together in 'banks' which plug into standard DIP sockets. One or more 'banks' can be plugged into sockets on a housing containing a chamber into which the micro-droplets are deposited. An air movement device may be included with the housing to disperse volatile material that has been ejected into the chamber. The chamber preferably contains a heatable surface onto which the volatile fluids are ejected from the orifices and whereby instantaneous volatilization of the fluid will take place. In an alternate embodiment, each self-contained replaceable cartridge has its own individual heatable surface in the form of a heater mounted adjacent the ejection orifice and one or more additional connecting pins to provide power to operate the heater. A multiplicity of different volatile fluids may be dispensed from a compact assembly in response to command signals from a controller connected to the dispensing assembly.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
