摘要： 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 second pressure wave has an amplitude and phase damping the reflected portion of the first pressure wave in order to the inhibit inadvertent ejection of satellite ink droplets.

摘要： 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.

摘要： 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. A pump in fluid communication with the gap is also provided for pumping the fluid through the gap. As the surface and/or orifice is cleaned, the contaminant is entrained in the fluid. A filter is provided to separate the contaminant from the fluid. In addition, a valve system in fluid communication with the gap is operable to direct flow of the fluid through the gap in a first direction and then in a second direction opposite the first direction to enhance cleaning effectiveness. Moreover, the print head itself has integral passageways formed therein for conducting the flow of fluid to the surface of the print head.

摘要： Printhead container and method. The container comprises an enclosure surrounding a printhead body having an ink channel terminating in a nozzle orifice. The ink channel has ink therein. The enclosure is capable of being pressurized to a predetermined internal pressure. The internal pressure acts on the ink to retain the ink in the channel, so that the ink is prevented from flowing along the channel and through the orifice. A one-way valve is in communication with the interior of the enclosure for ingress of a pressurizing medium into the interior of the enclosure, while avoiding reverse flow through the valve in order to allow sustained pressurization of the enclosure. Moreover, a support frame disposed in the enclosure may be provided, the frame defining a well sized to matingly receive the printhead body for constraining movement of the printhead body during transport of the enclosure.

摘要： An electronic camera useful with a peripheral processor comprises an image sensor for producing image data, an output storage section, an electronic control processor for transferring the image data to the storage section, and a mode selector for indicating whether the camera is used for normal format pictures or for panoramic pictures. When the mode selector is set for panoramic pictures, the electronic control processor includes a panoramic mode indicator in a header with the image data. The peripheral processor keys on the mode indicator to process the tagged images into a panoramic picture. By further including alignment indicia in a view finder in the camera to aid the user in aligning adjacent images, the peripheral processor utilizes image addresses corresponding to the indicia locations to process the tagged images.

摘要： A public key encryption system for authenticating an image includes a digital camera having embedded therein a private key unique to the digital camera. A known public key uniquely based upon the private key is used to decrypt digital data encrypted with the private key to establish authenticity of the image. The encryption system further comprises means for generating one or more patterns each composed of at least one individual area that is visible together with the image of the object, means for designating at least one individual area as an active area of the image suitable for authentication and for generating location data identifying the active area, and means for calculating image hash from image data of the active area of the image using a predetermined hash algorithm. The image hash is then encrypted with the embedded private key, thereby producing a digital signature uniquely associated with the active area of the image, and the image data, the digital signature, and the location data of said active area are stored in a digital record. By confining encryption to this selected region of interest, power requirements for subsequent hashing and encryption are reduced, which is an advantage for portable devices such as a digital camera.
