  • Patent number: 5915003
    Abstract: A sketching system sketches first notes to be transmitted over a telephone line receives second notes from another sketching system. The sketching system includes a signal de-combiner device, receiving the second notes from the another sketching system and voice data as a combined signal via the telephone line and de-combining the combined signal into the second notes and the voice data. In addition, the sketching system includes a sketching unit connected to the signal de-combiner. The sketching unit includes a note displaying device displaying the first and second notes, a note generating device generating the first notes, and a processor connected to the note displaying and generating devices and to the signal de-combiner, receiving the first notes from the note generating device, receiving the second notes to the note displaying device.

  • Patent number: 5550646
    Abstract: An image communication system and method includes an image capture device which utilizes CCD technology to "take a picture", i.e., to capture an image, and then to generate a digital representation of that image which may be applied to a fax modem and then transmitted to a remote facsimile machine via a telephone communication link. The digital image is processed, such as by dithering, to enhance its presentability, so that shades of gray present in a conventional black and white photograph are converted to a pattern of black and white dots which retains the character of the original image in spite of subsequent facsimile transmission. The image capture device may include a printer and a memory for storing multiple images as well as the destination numbers of facsimile machines which are intended to receive copies of the images.
