Title: Ccm calculating system, ccm calculating method and recording medium
Inventor: KOBAYASHI OSAMU
IPC: H04N1/60
Filed: 2001-06-13
Abstract: The object of the invention is to provide a CCM calculating system being relatively inexpensive and alleviating the necessity of a spectrophotometer, a CCM calculating method and a recording medium. A CCM calculating system according to the invention calculates a blending ratio of colorants based on stored color data 16. The system has an input device 5(20b) for inputting data of color specification values corresponding to a desired target color and a data operation unit 1(20c) for calculating a blending ratio of colorants for reproducing the target color, based on the input data of color specification values and stored color data. Since the blending ratio of colorants for reproducing the desired target color may be calculated based on the input color specification value data and stored color data, such CCM calculation may be performed without the necessity of a spectrophotometer.

IPC: H04B10/275
Filed: 2001-10-19
Abstract: A method and apparatus are disclosed for terminating optical links in an optical network based on performance requirements. The present invention forces the termination of the received optical signals at each node only on the protection ring and does not force termination on the working ring, unless necessary to satisfy performance requirements. A signal on an end-to-end light path on the working ring is terminated only when required by engineering rules, such as signal-to-noise requirements. Specifically, the present invention does not force terminate an end-to-end light path on the working ring at a given node (or on a link between two nodes) unless the signal will fail to meet certain criteria, such as a minimum optical signal-to-noise ratio, at the next node.

Abstract: A system and method for laser light amplification provides amplification of a laser light emitted from a laser light source as low-amplification seed laser light signal. The low-amplification seed laser light signal is transmitted to an amplification component. The amplification component amplifies the low-amplification seed laser light signal by stimulating emissions of the population inversion provided by a pumping diode to generate an amplified laser light signal. The system and method further directs the amplified laser light signal to an output destination. The result of the present invention is a system and method of operation providing higher pulse rates, improved pointing stability, and optionally variable pulse rates for a variety of uses, including for non-destructive laser ultrasonic testing of materials.

Title: Method for compensating the digital watermarking distortion on a multimedia signal
Inventor: WORNELL GREGORY W
IPC: G06T1/00
Filed: 2000-04-26
Abstract: A system provides distortion compensation when watermarking a host signal (101). A system includes an ensemble designator (320) that designates a plurality of embedding generators, each corresponding to a single watermark-signal value of a co-processed group of one or more watermark-signal components. Also included is an embedding value generator that generates embedding values by each embedding generator (750). The system also has a point coder (330) that sets at least one host-signal value of one or more selected host-signal components to a first embedding value to form a composite-signal value. A distortion compensator (333) modifies at least one composite signal value. The distortion compensator includes a difference signal generator (910) that generates a difference signal component having a first difference-signal value that is the difference between a host-signal value and its corresponding composite-signal value. The distortion compensator also includes a difference signal processor (920) that scales the difference-signal value by a scaling factor. A distortion compensation combiner (930) then generates a distortion-compensated composite signal based on the scaled difference-signal value and the composite-signal value.
