Title: Multiresolution digital imagery photofinishing system
Inventor: KRISTY STEPHEN HENRY
IPC: H04N1/60
Filed: 1991-09-11
Granted: 1997-04-15
Abstract: A photoprocessing, photofinishing apparatus enables an unskilled consumer to personally customize and obtain high quality prints of photographic images without the intervention of a skilled technician. It also provides for the storage and retrieval of high resolution digitized color still images for playback to a variety of reproduction devices. The apparatus comprises a high resolution film scanner which scans 35mm film and outputs high resolution image signals. These signals are digitized and coupled to a host image data processing unit, which stores each image file in a multiresolution, hierarchical format that facilitates retrieval of images for reproduction by a variety of devices the resolution of which may vary from device to device, such as a low/moderate NTSC television monitor or a very high resolution color thermal printer. The host processor is coupled to an interactive display terminal, through which the customer may manipulate a low resolution version of a selected image file. The apparatus may also be used by a skilled photofinishing minilab operator to produce a permanent record of images that have been digitized from one or more photographic image sources. In this application, the host computer may be coupled to drive an optical compact disc recorder which writes each hierarchical image file and an appended header file to an optical compact disc. The customer may then play back the disc on a CD player modified for display on a home television monitor.

Title: Optical bus transmission method and transmitting-side encoder and receiving-side decoder therefor
Inventor: MAEZAWA KOUSUKI
IPC: H04L25/38
Filed: 1991-06-19
Granted: 1997-09-09
Abstract: The present invention relates to an optical bus transmission method wherein each terminal connected to an optical bus produces a narrow pulse synchronized with the rise of a leading pulse of a second one of first and second Manchester-biphase digital electric signals, a narrow pulse synchronized with the rise of each pulse of the first digital electric signal and a narrow pulse occurring every fixed period of time during the duration of each pulse.  The method is comprised of a step wherein the narrow pulses are converted into optical signals and transmitted as an optical pulse train to the optical bus, and a step wherein each terminal converts an optical pulse received from the optical bus into an electric pulse signal.  The method further includes a step wherein the electric signal is separated into its leading pulse and subsequent pulses. Each of the subsequent pulses is converted into a pulse of a pulse width equal to the fixed period of time to regenerate the first digital electric signal and the second digital electric signal is regenerated from a polarity-inverted version of the regenerated first digital electric signal and the leading pulse.

Filed: 1994-10-25
Granted: 1998-06-16
Abstract: An adjunct processor (16) sends an end-of-address indication, such as a pound sign, along with the address, such as an extension number, to which a call is to be transferred, to a switching system (12, 14). The sent end-of-address indication causes the switching system to not accept further addressing information from the caller (10), thus preventing the caller from modifying the sent address and effecting the transfer of the call to an address different from the sent address, such as a long-distance telephone number. Perpetration of adjunct-assisted toll fraud is prevented thereby.
