Abstract: The present invention provides a system for implementing a purchaser incentive program on a network-wide level. The system associates SKU and UPC data on a network level to provide consumers with a purchasing environment that is both convenient and cost-efficient. The association of SKU and UPC data at a network level also provides consumers with the ability to analyze their own purchase data for a variety of purposes, including analyses relating to the consumer's spending behaviors or patterns for example. In accordance with one aspect of the invention, the association of UPC and SKU data by the system facilitates a network-wide search for an item that a consumer desires to purchase under terms or conditions that are selected by the consumer and are therefore perceived to be optimal by that consumer.

Abstract: A method of supplying liquid ink to a printhead assembly including a carrier, a printhead die mounted on the carrier, and a fluid delivery assembly communicated with the carrier includes communicating a fluid manifold of the carrier with the printhead die, communicating the fluid delivery assembly with the fluid manifold of the carrier, and filling the fluid delivery assembly with a quantity of the liquid ink, including purging air from the fluid delivery assembly through a filter, wherein the filter includes a frame having an opening and a fluid passage communicated with the opening formed therein, filter material enclosing the opening and the fluid passage of the frame, first and second fluid ports communicated with the fluid passage, and a permeable material communicated with the first fluid port.

Abstract: A check valve includes two opposing sheets surfaces that are coupled together to form a flow channel there between. The flow channel has a first end, a second end and at least one direction-changing portion in between the first and second ends. A first opening is provided at the first end of the flow channel and a second opening is provided at the second end of the flow channel.

Abstract: An inkjet pen is disclosed having an interior chamber containing a pressure regulator. A filter within the interior chamber substantially surrounds the pressure regulator, providing a large filter surface area, and hence a low resistance to ink flow. The filter may be formed of a pleated filter material; the filter material may be retained by a rigid ink passage flange and a filter cap.

Abstract: A printhead assembly includes a carrier having a fluid manifold defined therein, a plurality of printhead dies each mounted on the carrier and communicating with the fluid manifold, and a fluid delivery assembly coupled with the carrier and communicating with the fluid manifold.

Abstract: A filter for a printhead assembly includes a frame having an opening formed therein, filter material enclosing the opening of the frame, and a fluid fitting associated with the frame, the fluid fitting including a fluid port offset from the frame and a fluid passage communicated with the opening of the frame and the fluid port.

Abstract: A printhead assembly includes a carrier having a fluid manifold defined therein, and a plurality of printhead dies each mounted on the carrier and including a first nozzle set and a second nozzle set. The fluid manifold includes a first chamber and a second chamber such that the first nozzle set of each of the printhead dies communicates with the first chamber of the fluid manifold and the second nozzle set of each of the printhead dies communicates with the second chamber of the fluid manifold.

Abstract: The present invention provides for a filter for an ink jet pen, comprising a filter material configured to attach to the pen, wherein a flow of ink through the filter material is substantially multidirectional. In a preferred aspect, an effective filtration surface area of the filter is substantially greater than any projection surface area of the filter. In another preferred aspect, the filter comprises a chamber at least partially bounded by the filter material, and a flow direction of ink into the chamber is substantially different than a flow direction of ink from the chamber.

Abstract: A printhead assembly includes a substrate having a first side and a second side opposite the first side, at least one electrical component mounted on the second side of the substrate, a substructure having a fluid manifold and at least one well isolated from the fluid manifold defined therein, and a plurality of printhead dies each mounted on the first side of the substrate. The substructure is disposed on the second side of the substrate such that the at least one electrical component is confined within the at least one well.
