  • Patent number: 6850652
    Abstract: A tactile kinesthetic assistant is a device that allows a person to use the senses of sight, touch and hearing to gather information. Tactile kinesthetic assistants can be used, for example, to help a person retrieve information related to a specific word or phrase (e.g., a student learning to read), to allow a person to determine the status of a person or thing (e.g., a nurse retrieving medical records), to allow a person to obtain current information (e.g., a stock broker retrieving stock prices). In one embodiment, a tactile kinesthetic assistant includes a thimble and an ear piece. The thimble includes a scanner that allows the user to scan one or more words. The representations of the one or more words are used to retrieve information via a network and the retrieved information is provided to the user through an ear piece.

  • Patent number: 6801342
    Abstract: An image scanner allows the reflection from the image on the face containing the image data to read of an original to strike on a one-dimensional image sensor and thus scans and reads the entire image on the original's face. The image scanner includes brightness sensing means for sensing ambient brightness and means for varying the reading speed of the one-dimensional image sensor in accordance with the brightness sensed by the brightness sensing means. In light surroundings, the scanner generates relatively fast clock signals, making the original's face scanning faster according to these clock signals, producing image data signals without saturating their output capacity. In dark surroundings, the scanner generates relatively slow clock signals, making the original's face scanning slower according to these signals, producing image data signals with a satisfactory S/N ratio.

The pads include pads through which a voltage or a ground potential is applied to active elements of pixels of a pixel region, pads through which voltages are inputted to amplifiers, and pads through which output signals of the amplifiers are outputted to the outside of the chip.

  • Patent number: 6704461
    Abstract: An image reading apparatus includes a plurality of reading sections (CCD elements) and reads a photographic photosensitive material by pre-set plural reading sections of the plurality of reading sections. In the image reading apparatus, on the basis of a value indicating an amount of deviation between an actual reading position and a predetermined proper reading position, the plural reading sections which read the photographic photosensitive material are suitably shifted from pre-set plural reading sections. Accordingly, even if a reading device deviates from its proper position, an entire range to be read of the photographic photosensitive material can be read. Specifically, first, a position H1, at which a reference position of the photographic photosensitive material is actually imaged on the reading device (a line CCD sensor), is fetched. Next, a proper imaging position H0, at which the reference position of the photographic photosensitive material should be imaged on the reading device, is fetched.

  • Patent number: 6684052
    Abstract: An imaging system includes two sets of cameras: a first set for capturing optical mark or optical character recognition data and a second set for capturing visual images. Full visual images of pages containing answers to open-ended questions are retained and are retrievable by a reader such that an area of interest wherein the answer is expected is displayed, but the remaining area is also available for viewing. The system permits the alignment of a page based upon edge detection if the page contains only an open-ended answer, obviating the need for timing tracks. Hardware and software elements cooperate to store the image temporarily in a server having a response time commensurate with the scanner. The image is then processed with the use of high-performance index imaging for optical storage and retrieval, and then routed to a long-term storage device.
