Abstract: Low acoustic solid wave attenuation structures are formed with an electroformed nickel mold, and are incorporated within acoustic ink emitters, between the focusing lens and surface of an ink layer. The structures have characteristics of low attenuation of acoustic waves to increase the efficiency of acoustic wave transmission within the acoustic ink emitter. Using the described structures, acoustic ink printers can accurately emit materials having high viscosity, including hot melt inks.

Abstract: In a printing system with multiple printheads, a spot of ink is created on a recording medium using up to N drops of ink fired from an ejector of one of the printheads. Each printhead has an array of ejectors. A single power supply drives the ejectors of the multiple printheads. Each of the printheads delivers a single color such as cyan, magenta, yellow, or black. A memory, which is coupled to the multiple printheads, records a printfile. Values in the printfile record channel values. Each channel value specifies how many drops of ink to deliver onto the recording medium over a spot cycle. The spot cycles of the multiple printheads, which consist of one to N actuation intervals, are desynchronized by operating the spot cycles out of phase with each other. The spot cycles of two printheads, for example, are desynchronized by beginning the spot cycle of one printhead a non-multiple of N drops prior to beginning the spot cycle of the other printhead.

Abstract: An out-of-plane micro-structure which can be used for on-chip integration of high-Q inductors and transformers places the magnetic field direction parallel to the substrate plane without requiring high aspect ratio processing. The photolithographically patterned coil structure includes an elastic member having an intrinsic stress profile. The intrinsic stress profile biases a free portion away from the substrate forming a loop winding. An anchor portion remains fixed to the substrate. The free portion end becomes a second anchor portion which may be connected to the substrate via soldering or plating. Alternately, the loop winding can be formed of two elastic members in which the free ends are joined in mid-air. A series of individual coil structures can be joined via their anchor portions to form inductors and transformers.

Abstract: In a photosensitive device wherein a photodiode is operated by placing an initial fat zero charge thereon before the integration of a light-induced signal, the actual dark level signal created by the fat zero charge is sampled with each readout from the photodiode, and then retransferred to the photodiode. After integration, the sampled dark level is subtracted from the total signal level on the photodiode. In this way both fixed-pattern and thermally-induced noise is obviated.

Abstract: A method for scanning a document includes: acquiring scanned image data from a first region of the document; determining an initial estimate of a document attribute using pixels in the first region; acquiring scanned image data from a second region of the document; processing pixels in the second region in accordance with the initial estimate; determining a second estimate of the document attribute using selected pixels in the second region; determining if the initial estimate is valid and if not, processing pixels within the image in accordance with the second estimate.

Abstract: Systems and methods to enable real-time and near real-time storyboarding on the World Wide Web in addition to a graphical user interface for video parsing and browsing the of the storyboard. Specifically, storyboarding can be accomplished on the World Wide Web by parsing an input video into representative or key frames. These frames then can be posted to a web document, or the like, for subsequent viewing by a user. This allows a video to be distilled down to the essential frames thus eliminating storage and bandwidth problems as well as eliminating the need for a user to view the entirety of the video. Furthermore, the graphical user interface allows a user to visually interact with an input video signal to determine the key or representative frames, or to retrieve video segments associated with already determined key frames.

Abstract: In a computer system comprising a screen, a screen saver determines if a predetermined time period lapses and, saves a screen when the predetermined time period has elapsed. When the screen saver runs, messages can be left, and, when a user is identified, he can gain access to the left messages.

Abstract: A thermal ink jet printhead for a printer has a temperature sensor attached thereto for monitoring the operating temperature thereof. A maximum printhead operating temperature is stored in a memory of the printer's control circuitry and, if the printhead temperature sensed by the temperature sensor during a printing operation exceeds the maximum operating temperature stored is the memory, a signal is generated indicating that the printhead has stopped ejecting ink droplets and must be checked for depriming or a depleted ink supply.

Abstract: A method and apparatus for facilitating communication about a document between two users creates autonomous, animated computer characters, or avatars, which are then attached to the document under discussion. The avatar is created by one user, who need not be the author of the document, and is attached to the document to represent a point of view. The avatar represents the physical likeness of its creator. The avatar is animated, using an avatar scripting language, to perform specified behaviors including pointing, walking and changing facial expressions. The avatar includes audio files that are synchronized with movement of the avatar's mouth to provide an audio message.

Abstract: A system is provided for improving security during data transfer. A transmitter side transfer controller (12) divides data to be transferred into a plurality of pieces, removes a portion of data from each piece and encrypts the piece, and uploads each encrypted piece to different relay servers (22) on the Internet (20). The transmitter side transfer controller (12) also provides a receiver side transfer controller (12) information indicating which piece is uploaded to which relay server (22) using a secure communication protocol. The data of the fragment removed from each piece is transmitted to the receiver side transfer controller (12) separately from the encrypted pieces. The receiver side transfer controller (12) downloads the encrypted pieces each uploaded to the relay server (22), decodes the encrypted pieces, complements the decoded data with the data of the fragment to restore the state before the removal, and assembles the restored pieces to obtain the original data to be transferred.

A request to use a digital work in accordance with usage rights associated with the digital work is received. The usage rights specify a manner of use and an access specification indicating a security class. A security level of a repository controlling the requested use is determined. The request is granted and the user is permitted to exercise the manner of use specified in the usage rights associated with the digital work if the security level of the repository corresponds to the security class of the access specification specified in the usage rights associated with the digital work.

Abstract: A method for neutral pixel detection using color space feature vectors wherein one color space coordinate represents lightness is provided. The method includes the following steps: a) receiving an input image represented in a first color space; b) converting the input image to a second color space wherein one coordinate represents lightness; c) selecting a pixel in the second color space representation to be classified; d) computing second color space feature vectors associated with the selected pixel; and e) classifying the selected pixel between neutral and color classes based on the values computed for the second color space feature vectors. Typically, the input image is processed using a smoothing filter to create a smoothed input image prior to the conversion to the second color space. The method can be adapted to page processing or strip processing schemes with respect to the input image.
