Abstract: Provided are methods, compositions, kits and the like, for diagnosing and differentiating patients with systemic juvenile idiopathic arthritis (sJIA) from patients with Kawasaki disease (KD) and other febrile illnesses.

Abstract: The present disclosure is directed toward methods for obtaining and processing ocular fluid samples from a subject in preparation for further analysis for diagnostic purposes. Ocular fluid provides a superior sample medium for biomarker analysis as compared to other biological media such as blood, serum, saliva, urine or bodily secretions. Proper sample collection and processing is critical for further use as a diagnostic medium as studies have shown that biomarkers found in ocular fluid can degrade quickly if mishandled.

Abstract: The present disclosure is directed toward methods for detecting brain related maladies in a subject by measuring levels of at least one of the identified biomarkers, as compared to a control. Brain related maladies include physical trauma to the brain, neurodegenerative disorders, and mental illness. The detection of the target biomarkers in ocular fluid provides a simpler and more effective sample matrix as compared to other biological matrices.

Abstract: A photographic system involves the collection of data from a scene, e.g., a visitor attraction site, that is capable of interactive communication with a user. The attraction site stores content data related to the site, and the user communicates with the attraction site through a camera capable of communication with the site. Besides capturing an image associated with the site, the camera stores predetermined personality data that relates an interest of the user to at least a portion of the content data and includes means for transferring the personality data to the attraction site. The camera further includes means for receiving and displaying the portion of the content data from the attraction site, and a user interface for selecting from the displayed content data that part which the user wants to keep. In this manner, information relevant to a user's interests about a photographed item can be easily requested, accessed and stored with the specific pictures that the user has captured.

Abstract: Apparatus for separating a receiver from a micro-fluidic contact print head after ink image pixels have been printed by the print head on the receiver, including a print head having a plurality of ink channels for delivering ink to the receiver when the receiver is in ink transfer contact with the print head; including an air supply device and air plenum which are associated with each ink channel and defining an air channel for conducting air to the air plenum; and the apparatus is effective after the ink has been transferred from the plurality of ink channels to the receiver for causing air to be delivered from the air supply device to the air channel and into the air plenum to exert a pressure which causes the separation of the receiver from the print head.

Abstract: An ink jet printer and method capable of forming a plurality of registration marks on a receiver and sensing the marks formed thereby. The method includes a print head for printing an image of predetermined length on the receiver. The receiver has an image area for receiving the image therein and a border area adjacent to the image area. A marker forms the plurality of registration marks in the border area, so that the marks extend the length of the image. In addition, a sensor is disposed in sensing relationship to the marks for sensing the marks. The invention provides a combination marker for marking a receiver and a sensor for sensing the marks so that each image line is in registration with other lines of the image. Also, use of the invention avoids need for costly precision motors to advance the receiver during printing of image lines.

Abstract: An apparatus for removing foam from an ink container of a printer including a nozzle disposed within the ink container such that the nozzle floats upon a surface of the ink located within the container. The nozzle contains a plurality of inlet channels located therein and an outlet communicating with the inlet channels. A vacuum source is coupled with the outlet of the nozzle to create a suction force within the inlet channels of the nozzle to remove foam located on the surface of the ink. As the level of the ink is depleted or added to the container, the nozzle remains on the surface of the ink and the foam is actively removed from the surface through the inlet channels.

Abstract: An imaging apparatus capable of inhibiting inadvertent ejection of a satellite ink droplet and method of assembling same. The imaging apparatus comprises a print head transducer including a pair of sidewalls defining a chamber therebetween, the channel having the ink body disposed therein. The transducer is in fluid communication with the ink body for inducing a first pressure wave in the ink body in order to eject an ink droplet. A waveform generator is connected to the transducer for supplying voltage waveforms to the transducer, so that the transducer induces pressure waves in the ink body. However, the first pressure wave has a reflected portion formed by the first pressure wave reflecting from the sidewalls. The reflected portion is sufficient to otherwise inadvertently eject unintended satellite ink droplets. Thus, a sensor is in fluid communication with the ink body for sensing the reflected portion and is connected to the transducer for inducing a second pressure wave in the ink body.

The method comprises a piston for pressurizing an ink body so that an ink meniscus extends from the ink body. An ink droplet separator is also provided for lowering surface tension of the meniscus as the meniscus extends from the ink body. The extended meniscus severs from the ink body to form an ink droplet as the droplet separator lowers the surface tension to a predetermined value.

Abstract: Pagewidth image forming system and method. The system features a plurality of mechanically isolated transducers capable of pressurizing an ink body associated with each of plural nozzle so that an ink meniscus extends from the ink body. The transducers are operated such that the ink bodies are uniformily intermittently pressurized. An ink droplet separator is also provided for lowering surface tension of the meniscus. In this regard, the droplet separator lowers the surface tension of the meniscus at a selected nozzle as the meniscus extends from the ink body, so that the meniscus forms a neck portion thereof. The extended meniscus severs from the ink body at the neck portion as the droplet separator lowers the surface tension to a predetermined value so as to form an ink droplet.

To avoid formation of satellite ink droplets, a sensor is in fluid communication with the ink body for sensing the reflected portion.

Abstract: Self-cleaning printer system with reverse fluid flow and method of assembling the printer system. The printer system comprises a print head defining a plurality of ink channels therein, each ink channel terminating in an ink ejection orifice. The print head also has a surface thereon surrounding all the orifices. Contaminant may reside on the surface and also may completely or partially obstruct the orifice. Therefore, a cleaning assembly is disposed relative to the surface and/or orifice for directing a flow of fluid along the surface and/or across the orifice to clean the contaminant from the surface and/or orifice. The cleaning assembly includes a septum disposed opposite the surface or orifice for defining a gap therebetween. Presence of the septum accelerates the flow of fluid through the gap to induce a hydrodynamic shearing force in the fluid. This shearing force acts against the contaminant to clean the contaminant from the surface and/or orifice.
