Abstract: A controller emulator, coupled to an interface that exposes the controller emulator to inputs from external sources, provides one or more control signals to a process simulator and a deep learning process. In response, the process simulator simulates response data that is provided to the deep learning processor. The deep learning processor generates expected response data and expected behavioral pattern data for the one or more control signals, as well as actual behavioral pattern data for the simulated response data. A comparison of at least one of the simulated response data to the expected response data and the actual behavioral pattern data to the expected behavioral pattern data is performed to determine whether anomalous activity is detected. As a result of detecting anomalous activity, one or more operations are performed to address the anomalous activity.

Abstract: An enclosure for an ink reservoir bag in an ink delivery system for an ink cartridge comprises a tray and a cover for the tray. The tray includes a bottom wall having opposite ends and opposite sides, end walls extending upwardly from said bottom wall at the opposite ends and side walls extending upwardly from the bottom wall along the opposite sides. One of the end walls of the tray has a pair of openings therethrough between the side walls to receive fill and exit ports of the reservoir bag.

Abstract: An ink reservoir bag of flexible, plastic sheet material for an ink delivery system for an ink cartridge is constructed of two sheets of plastic material having peripheral edges bonded together to provide an ink chamber therebetween and has separate fill and exit ports opening into the chamber and respectively defined by a fill tube and an exit tube bonded to the bag between the peripheral edges thereof. Flexible tubing is connected to the exit port through a check valve interposed between the port and tubing, and a lure lock is interconnected with the fill tube to provide an injection sight for filling the bag. The bag is filled by connecting the tubing to a vacuum source, evacuating air from the bag and tubing, connecting the fill port to a source of ink and using the negative pressure to draw ink into the bag and tubing.

Abstract: An ink jet cartridge comprising an outer housing and an inner ink chamber has adjacent housing and chamber wall portions, and a coupling member for communicating the ink chamber with an external source of ink has an inner end extending through an oversized opening in the housing wall portion and into threaded interengagement with an opening through the chamber wall portion. The outer end of the coupling is outside the housing wall portion for connection to a source of ink.

Abstract: An ink jet cartridge for use in a continuous cartridge refill system has a top side, a front side, and a handle at the juncture therebetween. A flexible ink supply tube for connecting the cartridge with an ink reservoir extends through openings in the handle of the cartridge and is connected to a fitting on the top side of the cartridge which communicates the supply tube with the ink chamber of the cartridge. Routing of the tube through the handle provides strain relief for restraining the application of a pulling force on the tubing at the point of connection thereof with the coupling.

Abstract: An ink jet cartridge lid has a body having a first planar side and a second planar side opposite the first side. The first planar side has a raised portion having a first angled end wall and a second angled end wall. A third, side wall and a fourth, side wall each connect the first end wall to the second end wall of the lid. The second planar side has a recess therein with projections for compressing a foam insert. The lid is installed onto an ink jet cartridge having an open-ended cavity and a foam insert disposed therein.

Abstract: An ink cartridge for insertion into a cartridge holder has an ink supply tube coupled therewith for delivering ink to the cartridge from a remote source, and a clamping device on said cartridge is operable to open the supply tube when the cartridge is introduced into the holder and to close the tube when the cartridge is removed from the holder.

Abstract: A device for protecting and sealing ink nozzles of an ink jet cartridge includes a sealing member having a contact portion with a curvilinear contact face for sealing against the nozzles. The cartridge nozzle includes a nozzle plate surrounding the associated ink nozzles which may be in rows. A transport clip for attachment to the ink jet cartridge supports the sealing member for compressional engagement with the nozzle portion thereof when the clip and cartridge are interengaged.

Abstract: An ink delivery system for an ink cartridge comprises an ink reservoir bag of flexible, plastic sheet material, an ink cartridge and flexible tubing connecting the bag and cartridge in flow communication with one another. The bag is constructed of two sheets of plastic material having peripheral edges bonded together to provide an ink chamber therebetween and has separate fill and exit ports opening into the chamber and respectively defined by a fill tube and an exit tube bonded to the bag between the peripheral edges thereof. The flexible tubing is connected to the exit port through a check valve interposed between the port and tubing, and a lure lock is interconnected with the fill tube to provide an injection sight for filling the bag. The bag is enclosed in a container having openings through which the fill and exit ports extend.

Abstract: A method of filling ink into a dual chamber ink-jet cartridge for use with an ink-jet printer includes applying a vacuum to the cartridge through a fill hole of the cartridge to substantially eliminate air within an ink absorbing member of the cartridge. The fill hole is sealed and then ink is pressure filled into the cartridge through the fill hole. A vacuum is again applied to the cartridge to substantially eliminate any residual air in the cartridge due to the pressure filling of the ink. The fill hole may be positioned over a free ink chamber or over the ink absorbing member of the cartridge. The vacuum includes applying a negative pressure of about 27.5 in/Hg. The negative pressure is applied at a cycle rate of 5-30 seconds.

Abstract: An aperture provided in a bottom wall of an ink cartridge is designed to break the surface tension of the ink as the ink proceeds toward an outlet port. For example, serrated edges, tapering conformations, cruciform dividing walls, different diameter regions in the outlet passage, etc. are all designed to prevent the formation of large bubbles or preclude the migration of air bubbles to the region of the outlet passage where the print needle of an associated printer extends.

Abstract: An ink tank cartridge includes a housing with a bottom wall and a plurality of side walls forming a cavity. An ink supply member having a port extends from the housing. A seal member is inserted into the ink supply member for sealing the port. A retaining capis used to hold the seal member in place. The retaining cap has an opening to provide access to the seal member. An ink supply needle passes through the cap opening to pierce the seam member. The retaining cap has slots to receive ribs located on the outlet port.
