Patent CA-2227957-A1 (CA)
Title: Display systems with multiple view optics
Inventor: GELARDI JOHN A
IPC: G02B30/27
Filed: 1996-07-23
Abstract: Optical arrangements are provided by which observers of flat containers or display boxes, such as compact disc (CD) jewel boxes (100), can be presented with different information when looking at one of the box's surfaces from different angular perspectives. Advantageously, parallax effects are compensated where the size of the observable images and the viewing distance create undesirable visual artifacts. Horizontally and vertically oriented lenticulated panels (112) are used in combination with interlaced images (146, 148) to convey the differently coded views without the need for physically manipulating such boxes as in the past to see equivalent information. Printed informational inserts (140) are provided with interlaced images (146, 148). These arrangements enhance the possibilities for displaying more and different kinds of information on a given box or display surface area.

IPC: H04N5/913
Filed: 1992-11-12
Abstract: L'invention est un système de brouillage vidéo qui produit une fluctuation aléatoire, par exemple un décalage temporel, de la position de la partie active d'une trame vidéo sans perturber le signal de synchronisation horizontale et la salve couleur dans chaque ligne vidéo, ce qui en fait un système de protection et de camouflage. On accentue la protection en remplissant l'intervalle entre le début nominal de la partie active de la trame vidéo et le début réel de celle-ci par un signal vidéo synthétisé qui reproduit la partie active adjacente de la trame vidéo au moyen d'une configuration de remplissage engendrée numériquement. De plus, l'emplacement de cet intervalle est camouflé au moyen d'un bruit aléatoire superposé. On accentue le camouflage en produisant une fluctuation temporelle du signal de synchronisation horizontale au moyen d'une ou deux fréquences et en modifiant de façon aléatoire la position du signal de synchronisation verticale. Le codage numérique NTSC de l'invention est simplifié par l'utilisation de deux canaux seulement,  le canal de chrominance et le canal de luminance, et par l'utilisation d'un circuit hétérodyne pour stabiliser la chrominance. On accentue ce codage en fournissant, au moyen du canal de chrominance, des détails qui sont perdus normalement. De plus, un signal vidéo non standard peut être incorporé a une partie de la salve couleur du palier avant de la suppression de ligne, ce qui permet d'utiliser un décodeur relativement simple.

Title: Method of accessing an ip in an isdn network with partial release
Inventor: BAKER NIGEL H
IPC: H04Q11/04
Filed: 1998-07-16
Abstract: A method and system in an ISDN network for exchanging call control information between a switch and an IP, and for call set-up and call clearing for intermediate access to an IP. The invention utilizes the User-User Information (UUI) element of the Q.931 messages to exchange call information between a switch and an IP. A subscriber call results in a connection being established to an IP. A request to the IP is encoded in the UUI element of a SETUP message, and call routing information is encoded in the UUI element of a returned DISCONNECT message. The DISCONNECT message causes a partial call release of only the circuit segments from the IP back to the switch. The circuit segments from the calling party to the switch are maintained. The switch then routes the user call to a final destination based on information contained in the UUI element of the DISCONNECT message.
Patent CA-2245389-A1 (CA)
Inventor: GOLUB ILYA
IPC: G02B6/34
Filed: 1998-08-24
Abstract: In a wavelength-division multiplexer/demultiplexer, which may be of the free-space kind, which uses a diffraction grating or other such angularly-dispersive element, a substantially flat spectral response is obtained by spatially-shaping the light beam(s) to modify the passband response in the dispersion plane. The spatial shaping may be obtained by means of a plurality of microlenses disposed adjacent a plurality of ports through which pass a corresponding plurality of angularly-dispersed light beams having different centre frequencies/wavelengths. Each microlens may be a cylindrical lens arranged with its cylindrical axis normal to the dispersion plane so as to shape the light beam in only one direction, i.e. that of the dispersion plane. The spatial shaping may be obtained by means of a single lens, conveniently a microlens, disposed adjacent a WDM port through which the wavelength division multiplexed light beam passes. Alternatively, a plurality of microlenses may be provided adjacent the plurality of ports and a single microlens may then be provided adjacent the single WDM port. The plurality of microlenses and the single microlens cooperate to provide a very small loss multiplexer/demultiplexer with a broad gaussian-type spectral response. The diffraction grating may be reflective or transmissive and may be a concave one so as to combine the functions of a grating and a lens. The microlenses could be spherical lenses, diffractive-type elements, and so on. Other dispersive elements, such as prisms, etc., may be used instead of the diffraction grating. By reversing the light ray direction, the demultiplexer can act as a multiplexer. One-dimensional spatial-shaping may be implemented in waveguide WDM devices.
