Patent CA-2243648-A1 (CA)
Inventor: CHRISTOPOULOS CHARILAOS
IPC: H04N7/26
Filed: 1997-03-05
Abstract: A method and a transmission system for use in coding and Progressive Image Transmission (PIT), in which the transmitter at the initial stages of the transmission uses a Region Based Coding (RBC) scheme (905) in order to provide the receiver with an image of good visual quality at a high compression ratio, which the RBC is known to be able to provide. At a later stage of the transmission, when the visual quality of the RBC image is no longer superior to other compression techniques such as JPEG, the PIT switches (903) use a continuous tone compressor (907) for the further transmission, without losing the information contained in the RBC image already transmitted. Also a hybrid RBC-DCT (Discrete Cosine Transform) is used for further improving the performance of the transmission scheme, in which the image segmented by the RBC algorithm is divided into rectangular blocks, and those blocs that are fully contained inside a region of the segmented image are transmitted using predefined base functions such as DCT  base functions. Also a method for video coding using a similar scheme is disclosed.

Title: Method of distributing data packets of system software
Inventor: CESAR BOZO
IPC: G06F8/65
Filed: 1998-09-22
Abstract: In a point-to-multipoint system (SYS), particularly a video-on-demand system, comprising a send unit (SERVER) in the form of a server and a plurality of receive units (DEC) in the form of decoders, a new version of the system software for the decoders is to be transferred to the latter. This is done by taking the following steps: 1. An announce signal containing the information that the new system software or part thereof will subsequently be transferred is transmitted from the server to all decoders simultaneously. 2. The system software or part thereof is transferred in the form of data packets from the server to all decoders simultaneously. By the advance information in the form of an announce signal which is transmitted to all decoders by the broadcast method, the decoders are notified of the forthcoming transmission of the current version of the system software, whereupon they can prepare for the reception of the new version. The new version is also transmitted by the broadcast method, and ideally only once.

Abstract: A fastener system for use with personal care articles includes a substrate formed by a bodyside liner and an outer cover.  Fastening tabs are secured to the substrate at opposing sides of the rear portion of the article.  The fastening tabs include friction zones that, when the tabs are mounted to the article. provide substantially no securement to the article. and securing zones that secure the respective fastening tabs to the outer cover at a front portion of the article. The friction zones prevent surface-to-surface radial shifting or bending of the front portion with respect to the fastening tabs of the article during regular usage.  In one embodiment. a tab substrate provides a mounting surface for a friction element and a securing element which form the respective friction zone and securing zone.  In another embodiment. the friction element functions as a substrate supporting the securing element.  The friction element resists relative movement of the front portion of the article with respect to the rear portion and thus stabilizes the article on the wearer

Title: Acoustic horn for use in cellular flip phones
Inventor: RABE KARL W
IPC: H04M1/03
Filed: 1997-05-02
Abstract: A pivotable flip element for use with hand-held radiophone units is specially configured to provide highly efficient coupling of acoustic energy into and out of the radiophone by virtue or an acoustic horn precisely formed as an interior cavity of the planar pivotable element. When arranged as a device for coupling acoustic energy into a microphone fixedly mounted to the radiophone housing, incident sound is directed from the horn mouth to its throat section, and thereafter through a rotary acoustic joint to an input channel to the microphone. The continuously rotatable rotary joint accommodates flip element rotations, allowing for the dual-purpose operations of protecting and covering the radiophone keyboard when not in use, and efficient input sound coupling when deployed.

Patent CA-2266168-A1 (CA)
Inventor: SCHMITZER HEIDRUN
IPC: H04B10/2569
Filed: 1999-03-18
Abstract: The present invention relates to a method and an apparatus for compensating for polarization mode dispersion in an optical transmission line (9, 9') with transmission characteristics that are dependent on polarization, in particular in optical fibres and cables with not only random but also with preferred double refraction. A compensation element(1, 1', 1"), preferably a double refracting fibre that contains polarization is incorporated ahead of or after the transmission line (9,9'), and the length of this is balanced by non-destructive means using an interference device (2, 2', 2"), in particular a pressure mechanism. Because of the interference, the polarization states P L and P S are mixed and this defines the length of the compensation fibre on which a delay time difference between the partial waves with polarizations P L and P S is built up or broken down, this compensating for the delay time difference T within the transmission line (9, 9')

Inventor: OKADA HIROHARU

Filed: 1997-12-22
Abstract: In the processing circuit layer (106) of a card mounted with circuit chip, a processing section which is incorporated with a nonvolatile memory, MODEM  circuit, and capacitor, and performs communication processing is constituted.  In the constitution of the layer (106), in addition, a coil (44) constituted by forming a metallic wire in a loop-like shape is provided. Since a communicating function is obtained by only using one IC chip (104) in which the processing section and an antenna function are integrated, no wiring is required on the outside of the chip (104). Therefore, no wiring disconnection, etc., occurs. In addition, the assemblage of a card mounted with circuit chip becomes extremely easier. As a result, a highly reliable and inexpensive card mounted with circuit chip can be obtained.

Title: Bir-4-s2 adiabatic rf pulses, use therefor and method of creating the same
Inventor: COTE JEAN-CHARLES
IPC: G01R33/48
Filed: 1999-06-29
Abstract: Adiabatic RF pulses are very useful in MRI when precise flip angles are needed. Unfortunately, adiabatic pulses suffer from a long application time and a high SAR. In this article, we introduce a new concept to modify the usual adiabatic pulse into a "pseudo-adiabatic" pulse having a shorter application time and lower SAR. For example, a BIR-4 of 32 ms of application time and a relative SAR of 20 will be transformed into a BIR-4-S1 of 1 ms and relative SAR of 1. The new pulse obtained stays insensitive for a large B1 range but loses its slice selectivity to become a 3D pulse. Experimental results are presented to illustrate the sensitivity to B1 and B0.

Patent CA-2285128-A1 (CA)
Title: Switch for optical signals
Inventor: BAKER NIGEL
IPC: G02B6/43
Filed: 1999-10-06
Abstract: A cross-connect switch for switching optical signals, in particular, Dense Wavelength Division Multiplexed (DWDM) signals is disclosed. The switch includes a switching matrix for each of the predetermined wavelengths of the DWDM signals. The switching matrices include Micro-Electro-Mechanical (MEM) systems which have optically reflective elements, typically mirrors, arranged in rows and columns for switching an incoming optical signal travelling along a row of such elements to an output port aligned with a column of the elements. The switch has input demultiplexers to split an incoming DWDM signal into its component channel wavelengths, each of which is directed to a switching matrix where it is switched to an output port and recombined into an outgoing DWDM signal by a mutliplexer before being transmitted out of the switch. A wavelength-converting switch, connected across the switching matrices, is also included for switching channels between wavelengths. Thus, the switch provides port switching by virtue of the switching matrices and channel switching by virtue of the wavelength--converting switch, as well as a combination of both port and channel switching.
