Patent CA-2221546-A1 (CA)
Title: A telephony system and method of signalling
Inventor: CONSTANTINOF CRISTIAN M
IPC: H04L47/2466
Filed: 1997-11-19
Abstract: A telecommunication system and method of signalling are disclosed which enable service providers to integrate broadband network capability into their existing narrow band networks while being substantially transparent to existing narrow band signalling infrastructures such as the Common Channel Signalling System Number 7 (CCS7), currently in use. Significant advantages are realized through such a network system. Service providers, for example incumbent local exchange carriers (ILECs) now have access to BB connectivity while retaining the use of their extensive CCS7 signalling networks and Advanced Intelligent Network (AIN) resources. Investment in the CCS7 signalling infrastructure is hence not lost and the proven robustness and reliability of these networks is retained. Service providers can continue to take advantage of Intelligent Network capabilities in providing a large variety of voice services, but also to make available some of the current service features for future BB services. Furthermore each network is virtually independent of the other and can evolve as such. Telephony service call related signalling is able to be kept separate from the broadband network connectivity signalling thus allowing service providers to evolve their service specific signalling requirements independently of whatever BB networks are used now or in the future.

Abstract: A blank for producing a container which contains individual compartments. The object of the invention is to provide a blank from which scrap free production of containers is possible. The blank according to the invention has at least five rectangular plate parts which are joined by parallel longitudinal folding lines. In a finished container, they form bottom, first side wall, second side wall all of the same width, and intermediate plate parts being located between the side walls. In accordance with the invention, each transversely running section (18) on its tow ends within the width of intermediate plate part (3) intersects longitudinally running additional section (17). The two ends of the section are adjoined by a single obliquely running second additional section (19) extending to folding line (7) or (8) which borders intermediate plate part (3). A third transversely running additional section (15) connects, and on its outer end point (15a) coincides with one of the end points of the folding lines (16). The opposite end points (15a) are connected to one another through an additional folding line (20) disposed between them and running parallel to additional sections (17) in plate part (2) or (4) to form hexagonal fields (21).

Title: Process for correcting geometric errors in the transfer of information to a printing stock
Inventor: WEICHMANN ARMIN
IPC: H04N1/40
Filed: 1998-06-05
Abstract: A process corrects geometric errors in the transfer of information without mechanical intervention on the printing form, to compensate for the errors that occur and thus attain optimized print quality prior to imaging.  The corrections are visually indiscernible, so that the artifacts created in the printed result by the corrections do not stand out in the image. A device-independent description of the page information to be printed is converted by a Raster Imaging Process into at least one device-dependent digital matrix. Each matrix with m rows and n columns contains the information for a certain color to be printed. After the individual matrices are produced, they are supplied to a matrix manipulation device, which subjects each matrix to a correction transformation using specific parameters. After the matrices are adjusted, they are supplied by a matrix transfer device to the digital imaging devices in the printing mechanisms.

Inventor: OZAKI MASAYOSHI
IPC: G02F1/1335
Filed: 1999-01-18
Abstract: A liquid crystal display device of the present invention comprises a device substrate having a principal planar surface (hereafter referred to as a "first principal planar surface"), an opposed substrate having a principal planar surface (hereafter referred to as a "second principal planar surface"), and a liquid crystal layer and a sealing material sealed between the device substrate and the opposed substrate. The device substrate has TFT pixels on the first principal planar surface. On the other hand, the opposed substrate has microlenses formed on the second principal planar surface, spacers that are formed on the second principal planar surface and are arranged around the microlenses, and a cover glass (a cover body) provided on the microlenses and the spacers. Thus, a difference in level at the boundary between the display screen area and the other area is avoided, and the spacers can support the cover glass against the stress in the thickness direction, thus lessening swelling or distortion produced in the cover glass.      As a result, a liquid crystal display device in which less image-display irregularity can be found throughout a screen can be obtained.

Abstract: An infrared laser beam (B1) is applied from a transmitter (100) to a window pane (410) of a building (400), and a reflected beam (B2) is received by a receiver (200). On each of the target displays (113, 213), a laser spot (Q) picked up by a CCD camera is displayed. The receiver is provided therein with a photocell adapted to output an electric signal in accordance with the luminous energy of the reflected beam, and a knife edge for shielding a part of the reflected beam, and a component of vibration of the window pane due to an interior voice is detected as positional fluctuation of the reflected beam.  When a place of installation of the receiver is to be determined, the reflected beam is detected by using a beam detector (300) comprising a plurality of light receiving elements. The transmitter scans an object with the laser beam (B1) modulated by an audio-frequency so that the reflected beam (B) is easily detected. When the reflected beam hits the beam detector, the detector beeps vibratorily with an audio-frequency. The XY coordinates showing an actual scanning position are transmitted from the transmitter to the receiver, and shown on a coordinates display (212).

Title: Process for parametering a fuzzy automaton that compares a measurement system to a pattern signal
Inventor: LORENZ STEFFEN
IPC: B22D11/16
Filed: 1997-11-18
Abstract: The disclosed process enables a fuzzy automaton to be automatically parametered by generating transformation rules which include transition, stop, return and reset rules for the individual states of the fuzzy automaton which represent recognition probabilities. The advantage of the disclosed process is that it allows transformation rules for parametering the fuzzy automaton to be generated by the computer in a totally automatic manner. Even when the pattern signals change frequently, the parameters of the fuzzy automaton can be quickly, easily and flexibly altered.
