Patent CA-2194219-C (CA)
Title: Procede, emetteur et recepteur de transmission et de selection de programmes radiophoniques locaux dans un reseau de transmission sur onde commune
Inventor: ZUMKELLER MARKUS
IPC: H04L5/02
Filed: 1995-07-13
Granted: 2006-07-04
Abstract: Selon des procédés connus, on transmet des programmes radiophoniques par l'intermédiaire d'un réseau de transmission sur onde commune, ce qui permet d'assurer une utilisation particulièrement bonne de la largeur disponible de la bande de transmission, par exemple lors de l'exploitation sur onde commune d'émetteurs de radiodiffusion à l'échelle nationale. Un nouveau procédé permet de diviser un canal de transmission stéréo d'une émission radiophonique en deux canaux de transmission monophoniques et de transmettre par ceux-ci des programmes qui ne sont émis que par quelques émetteurs déterminés. L'information sur la division du canal de transmission stéréo en deux canaux de transmission monophoniques est en outre transmise à tout le réseau sur onde commune et permet à des récepteurs syntonisés sur ce canal de transmission de commuter automatiquement sur un mode d'évaluation monophonique du signal de réception. A un niveau régional, on peut également transmettre des informations supplémentaires qui indiquent quel canal de transmission monophonique peut être reçu. Alternativement, le récepteur ou l'utilisateur lui-même peut sélectionner le canal de transmission monophonique qu'il veut recevoir. Ce procédé peut être mis en oeuvre avec tous les modes de transmission sur onde commune.

Abstract: An electrical outlet box constituted of a plastic material and having wall structure including a hexagonal recess extending into a portion of the thickness of a wall. A through-hole is drillable within the recess to facilitate passage therethrough of a screw-threaded leading end of a cord grip into the outlet box. As a lock nut is torqued down onto the leading end of the cord grip within the outlet box, a hexagonal flange of the cord grip engages within the hexagonal recess so as to inhibit relative rotation between the cord grip and electrical outlet box to obviate the need for a wrench during the torquing down of the lock nut. This structure avoids the need for a custom designed cord grip and facilitates the use of existing cord grips normally designed for utilization with metallic electrical outlet boxes.

Granted: 2006-04-04
Abstract: L'invention a pour objet un cache-oreilles antibruit et un procédé pour modifier la caractéristique d'atténuation du bruit d'un cache-oreilles. Pour effectuer cette modification, l'anneau d'étanchéité (3) garni de mousse du cache-oreilles est placé dans le couvercle annulaire (5, 6) de ce dernier, avec un grand nombre d'ouvertures de ventilation (11) réparties avec uniformité le long de l'anneau d'étanchéité, ce qui modifie l'action de ressort pneumatique de l'anneau d'étanchéité. Les ouvertures de communication communiquent avec l'environnement sans communiquer avec l'intérieur du cache-oreilles. En réduisant fortement l'action de ressort pneumatique, on améliore l'atténuation des basses fréquences. La communication avec l'environnement constitue des "conduits acoustiques" (12) qui peuvent être dimensionnés pour assurer, en fonction de la résonance du conduit, une transmission sélective du bruit dans l'anneau d'étanchéité, ce qui modifie ainsi, de manière sélective, la caractéristique d'atténuation du bruit.

Title: Digital tv receivers with poly-phase analog-to-digital conversion of baseband symbol coding
Inventor: LIMBERG ALLEN LEROY
IPC: H04N5/44
Filed: 1998-06-23
Granted: 2002-03-05
Abstract: A digital television signal receiver includes, instead of a single flash converter as in the prior art, MN analog-to-digital converters of successive binary approximation type sampling baseband symbol coded signal on an MN-phase basis toprovide a respective digital output signal, each of which sampling phases is of one-M th symbol time duration, M being a positive integer at least one and N being a positive integer more than one. In a digital television signal receiver for ATSCstandard signals, N is twelve. Equalization filtering is carried forward on an MN-phase basis, with output signals from N of the phases being supplied to N trellis decoders as their respective input signals. Selecting M to be two facilitates symbol synchronization using first and second N-phase match filters for a prescribed pseudo-noise sequence in the data field synchronization codes. The first match filter responds to the digital output signals of the oddly ordinally numbered ones of the 2N analog-to-digital converters as equalized by the 2N-phase equalization filter; and the second match filter responds to the digital output signals of the evenly ordinally numbered ones of the 2N analog-to-digital converters as equalized by the 2N-phase equalization filter. A symbol synchronizer responds to differences in those match filter responses for adjusting the phase of sampling by the 2N analog-to-digitalconverters of successive binary approximation type.
