  • Patent number: 6994938
    Abstract: Methods for producing a hologram mask approximating the exposure produced by a non-holographic phase shifting photo mask are disclosed. One such method exposes a hologram recording material to a first object light, having passed through a first original mask and a first reference light having a difference in phase with the first object light, and further exposing the hologram recording material to a second object light, having passed through a second original mask and a second reference light having a difference in phase with the second object light, wherein first and second phase differences are not the same and wherein the exposed hologram material can be replayed to produce an exposed pattern that approximates an exposed pattern of a non-holographic phase shifting photomask.

  • Patent number: 6991457
    Abstract: An endodontic obturator includes a body and a disposable cartridge containing gutta percha that is couplable with the body. By containing the gutta percha in a disposable cartridge, a dentist or other medical technician does not have to clean the body or other components of the obturator, thus reducing the amount of time required to clean the obturator after use. The obturator also includes a heater operable to heat the gutta percha in the disposable cartridge and a thermal barrier operable to resist the flow of heat from the heater to the rest of the body. In addition, the obturator includes a mechanism operable to generate pressure in the disposable cartridge to dispense the gutta percha. With the thermal barrier, a portion of the obturator's body that a dentist or other medical technician might hold while injecting gutta percha into a patient's tooth may be kept relatively cool.

  • Patent number: 6990241
    Abstract: An image processing circuit includes a processor that receives an encoded portion of a first version of an image. The processor decodes this encoded portion directly into a decoded portion of a second version of the image, the second version having a resolution that is different than the resolution of the first version. Therefore, such an image processing circuit can decode an encoded hi-res version of an image directly into a decoded lo-res version of the image. Alternatively, the image processing circuit includes a processor that modifies a motion vector associated with a portion of a first version of a first image. The processor then identifies a portion of a second image to which the modified motion vector points, the second image having a different resolution than the first version of the first image.

  • Patent number: 6980458
    Abstract: A circuit for sensing a ferroelectric non-volatile information storage unit comprises a pre-charge circuit for applying a prescribed pre-charge voltage to a storage capacitor of the information storage unit. The pre-charge voltage causes a variation in a polarization charge of the storage capacitor, depending on an initial polarization state of the storage capacitor. A charge integration circuit integrates an electric charge proportional to the variation in polarization charge experienced by the storage capacitor. The charge integration circuit thus provides an output voltage depending on the polarization state of the storage capacitor.

  • Patent number: 6976216
    Abstract: Computer software allowing enhanced control of the playout of audio/video works on a computer system. In various embodiments, the software allows key events from dedicated audio/video keys, whether part of a full sized keyboard or on a hand held remote, to control the actions of an audio/video playout program without requiring the user to direct the key event focus of the operating system to the audio/video playout program. Also, the invention distinguishes between key presses from a local, full sized keyboard and key presses from a remote keyboard so that the audio/video playout program can enlarge its screen display when a key event is received from the remote keyboard. In one embodiment, the invention constantly instructs the operating system to move the focus to the audio/video playout program. In another embodiment, if the focus is received by any of various windows in a display, software associated with the window forwards to the audio/video playout program any key events received from audio/video keys.

  • Patent number: 6975559
    Abstract: The invention relates to a method for testing non-volatile memory devices that have at least one parallel communication interface, and a conventional matrix of non-volatile memory cells with respective reading, changing and erasing circuits, wherein during the testing procedure, a reading mode is entered for reading a memory location upon the rise edge of a control signal producing a corresponding ATD signal. Advantageously in the invention, a subsequent reading step is started also upon the fall edge of the control signal. In this way, at each cycle of the control signal two memory locations, instead of one as in the prior art, are read.

  • Patent number: 6966837
    Abstract: A video game system that includes a console and hand-held controllers with LCD screens. Each game operates in a simulated world populated with animated characters and static objects which are displayed on a TV screen, and are also displayed on the LCD screens of the hand-held controllers. While one part of the simulated world is displayed on the TV screen, different parts of the simulated world may appear on the LCD screens in a natural pictorial setting. Alternatively, some of the pictures displayed on LCD screens and TV screens may represent the same part of the simulated world at different times, or the same part at the same time. Pictures displayed on an LCD screen may appear concurrently or later on the TV screen. Objects and characters can be selected, moved, constructed, changed, or deleted by a player without revealing to other players these objects of interest or their disposition.
