Patent CA-2218980-A1 (CA)
Title: Time division demultiplexing using selective raman amplification
Inventor: STOLEN ROGERS HALL
IPC: H04J14/08
Filed: 1997-10-21
Abstract: An optical transmission system utilizing a nonlinear fiber demultiplexer. A timedivision multiplexed optical signal is transmitted via a first optical signal path. An optical pump pulse is transmitted via a second optical signal path. The optical pump pulses are synchronized to correspond to the pulses in the multiplexed optical signal for which extraction is desired. The first and second optical signal paths are coupled such that the portions of the multiplexed signals which are synchronized with the optical pump pulses are amplified through Raman gain. The resulting signal is detected and passed through a threshold detector which filters out pulses below an intensity threshold. The desired demultiplexed signal, which was amplified by the pump pulses, passes through the optical threshold detector as an electronic pulse.

Title: Method for an automated visual range measurement by means of a lidar system
Inventor: STREICHER JUERGEN
IPC: G01S17/95
Filed: 1997-10-17
Abstract: For automated visual range measurement by a LIDAR system, a distance measuring range is first determined through repeated evaluation of a voltage level U(R) which indicates the intensity of a threshold value. After random initialization of a start value, the start value is then replaced each time with a new mean visual range, resulting in iterative improvements, and the mean visual range in the determined range is then displayed automatically as soon as the visual range lies within the measuring range of the LIDAR system. Using the Klett method, the accuracy can be determined with the aid of a breaking-off criterion in the form of a threshold value with respect to a deviation percentage between a new and a previous calculation. With this method the deviation can be identified to an order of magnitude of about 10%.

Un sous-système de programme du ADCS reçoit une programmation à partir de fournisseurs de contenus et traite les signaux reçus pour le canal ainsi que le service VoD ou NVoD, puis il envoie le signal composite à un sous-système de transmission lequel module, canalise, amplifie, filtre et diffuse les signaux UHF numériques par la voie des ondes. Les spectateurs abonnés sont équipés d'une boîte de commande intelligente (ICB) configurée de manière appropriée pour recevoir, démoduler et décoder la diffusion UHF numérique et pour transmettre le signal résultant à un ou à plusieurs écrans ou autres dispositifs terminaux. L'ICB constitue également un commutateur matriciel ou passerelle destiné à recevoir des signaux par n'importe quelle voie de transmission disponible. En plus des ICB des spectateurs abonnés, un sous-système de voie de retour du système ADCS comprend une commande de cession ainsi qu'une unité administrative auquelle les ICB sont reliées par le réseau téléphonique public commuté ou autre système sans fil adapté de sorte que des données de transaction et de visualisation peuvent être reçues par les spectateurs abonnés. Le sous-système de voie de retour, à son tour, est relié au sous-système de programme afin d'acheminer vers ce sous-système toute information nécessaire ou utile à la fourniture de programmation.

The text is converted into a prosodic parameter string through synthesis-by-rule. The prosodic parameters corresponding to characters or character string to be corrected are corrected by the prosodic feature control commands of the I layer, and speech is synthesized from a parameter string containing the corrected prosodic parameters.

Abstract: In a receiver system (100) embodying the invention, the amplitude of the input signal (134) is sensed so that when it exceeds a predetermined level (202) the adaptation of adaptive filters (145, DFE) employed in the receiver is inhibited. In one embodiment of the invention the adaptation is inhibited for the extent of time that the sensed signal exceeds the predetermined level. In another embodiment of the invention, the adaptation is inhibited for a fixed period of time whenever the sensed signal exceeds the predetermined level. In still another embodiment of the invention, where the noise impulse has some repetitive pattern, an inhibiting signal is generated in anticipation of a repetitive noise impulse to inhibit adaptation of the adaptive filters during the period of time ("window") the noise impulse occurs.
