Abstract: Systems and methods are provided for evaluating a quality of an OCT image. The system includes a processor and a non-transitory computer readable medium that stores instructions executable by a processor to evaluate the quality of the OCT image. The executable instructions include an imager interface that receives an OCT image from an associated OCT imager and a feature extractor that generates at least one feature from the OCT image. An image evaluator determines an image quality metric from the at least one feature, and a user interface provides an output representing the image quality metric to a display.

Abstract: Systems and methods for extensible distributed configuration management of computer resources are described. Examples include a computer system including a processing unit and a storage device that stores a model definition and one or more asset plug-ins (each of the one or more asset plug-ins configured to expose at least one asset object that represents a computer resource). The computer system further includes memory that stores an asset model created based at least in part on the model definition, and a network interface configured to deploy to at least one managed system a compatible asset plug-in (the model definition including at least one conditional reference to the compatible asset plug-in). If a condition specified within the asset model is satisfied the processing unit selects the compatible asset plug-in for deployment, the condition being defined within the model definition and designated as applicable to the at least one conditional reference.

Abstract: A method of assembling a print head that includes the steps of: (a) providing a print head base including a nozzle and at least one ink channel; (b) mounting in fluid communication with the at least one ink channel of the print head base an ink regulator that includes: (i) a pressurized chamber including an ink inlet in fluid communication with an ink source, an ink outlet in fluid communication with the at least one ink channel of the print head base, and an exterior flexible wall having an inner surface facing an interior of the pressurized chamber, (ii) a valve biased to restrict fluid communication between the ink source and the pressurized chamber, where the exterior flexible wall actuates the valve to overcome the bias in response to a predetermined pressure differential across the exterior flexible wall to provide fluid communication between the ink source and the pressurized chamber, where the fluid communication between the pressurized chamber and the ink source decreases the pressure differential ac

Abstract: A method of welding a first material of an apparatus to a second, semi-crystalline material of the apparatus. The method includes the acts of heating a weld area with a first power intensity for one time period and heating the weld area with a second power intensity (not equivalent to the first power intensity) for another time period. The method also includes applying pressure to the weld area and producing a collapse distance within at least a portion of the weld area.

Abstract: A printing cartridge including a body, the body having a base and a tower defining a passageway. The tower is made from a first polymer material, and has a proximal end and a distal end. The proximal end is attached to the base. The distal end includes a surface. A frame, made of a second polymer material different from the first polymer material, is attached to the surface of the tower. A filter is attached to the frame and positioned to extend over the passageway.

Abstract: In a system for laser welding work pieces along a collapsing weld interface, methods and apparatus include providing welding pads and/or stop projections on either or both of the work pieces to control the manner or amount of collapse. Preferably, the stop projections exist a separation distance from the weld interface while the welding pads exist at and form a portion of the weld interface. Buffers are taught between the weld interface and stop projection. The work pieces may comprise inkjet printhead lids and bodies. In another aspect, the invention teaches methods of laser welding inkjet printhead lids and bodies according to whether the inkjet printhead body embodies a mono or color ink body type and especially includes selective control of one or more laser light sources to illuminate the inkjet printhead lid in a specific pattern of light.

Abstract: An apparatus for a laser transmission welding process for attaching a synthetic filter material to a filter tower frame in an ink jet printer cartridge. The apparatus includes a laser beam source and a filter clamping fixture containing a base, slide rods attached on first ends thereof to the base, an optics support plate attached to second ends of the slide rods, a movable platform for holding an ink cartridge slidably disposed on the slide rods between the base and the optics support plate, a platform moving device for translating the platform to and from a laser welding position, a laser beam transparent plate suspended by support legs from the optics support plate to a position between the movable platform and the optics support plate. The apparatus greatly improves synthetic filter attachment to a filter tower frame in an ink cartridge.
