Title: Computer telephony integration

IPC: H04M3/533
Filed: 2002-03-18
Granted: 2007-10-09
Abstract: In a CTI system an incoming call is alerted to the called user's list of users who have expressed a primary level of interest in that called user's incoming calls, and the call is routed by the PBX to a Voicemail system if, for example the call is not answered within a predetermined time. The Voicemail system plays an announcement inviting the caller to key "one" to have the call re-presented, and if that digit is keyed by the caller, the Voicemail system makes a call to a predetermined extension of the PBX. The PBX recognises, e.g.  by using call ID or DNIS, that the call received on that extension is a re-presented call, and alerts the called user's list of users who have expressed a secondary level of interest, with or without alerting the "primary" list users. A tertiary list of users who have expressed a tertiary level of interest in that called user's incoming calls may be used in the event that the call is routed to the Voicemail system for a second time and the caller again keys "one".

Abstract: A movable barrier operator (10) can have at least two automatic modes of operation. These modes of operation can differ from one another at least with respect to their respective utilized maximum-applied-force thresholds, such that one of the modes of operation correlates to a reduced maximum-applied-force threshold. Selection between these available maximum-applied-force thresholds can be based, at least in part, upon whether an obstacle detector is operably coupled to the movable barrier operator. In one embodiment, a primary controller (30) and a secondary controller (31) can be utilized to effect the controlled selection and usage of the available maximum-applied-force thresholds. In another embodiment, maximum permitted speed of travel for the movable barrier can also be determined, at least in part, as a function of whether an obstacle detector is available to the movable barrier operator.

Abstract: On connaît depuis longtemps déjà les installations d'énergie éolienne comprenant des pales de rotor de tous types. On sait également que, dans certaines situations, les installations d'énergie éolienne doivent être équipées d'un phare de danger, afin d'informer à temps la circulation aérienne dans la zone de l'installation d'énergie éolienne de l'existence de cette installation d'énergie éolienne. A cette fin, on peut également appliquer de la peinture de signalisation sur les pales de rotor de façon à éviter la collision d'un avion, notamment d'un avion militaire, avec une installation d'énergie éolienne ou avec son rotor. L'objectif de la présente invention est d'utiliser un éclairage des bouts de pale de rotor plus fiable que jusqu'à présent et de pouvoir supprimer dans la mesure du possible les éventuelles détériorations de manière extrêmement rapide et plus simple qu'auparavant. Cette invention concerne une pale de rotor pour installation d'énergie éolienne comprenant un raccord de pale de rotor sur un moyeu de l'installation d'énergie éolienne et un bout de pale de rotor sur l'extrémité de la pale de rotor qui est opposée au raccord de pale de rotor, caractérisée en ce qu'au moins un guide d'ondes optiques est installé depuis le raccord de pale de rotor jusqu'au bout de pale de rotor.

Abstract: L'invention porte sur des techniques de programmation de terminaux pour la transmission de données sur la liaison descendante et/ou montante d'un système MIMO-OFDM en fonction des "signatures" spatiales et ou de fréquence des terminaux. Un programmateur forme un ou plusieurs ensembles de terminaux pour une éventuelle transmission de données (liaison descendante ou montante) pour chaque bande d'un nombre de bandes de fréquence. Une ou plusieurs sous-hypothèses peuvent également être établies pour chaque hypothèse, chaque sous-hypothèse correspondant à (1) des affectations spécifiques d'antennes de transmission aux terminaux de l'hypothèse (pour la liaison descendante) ou (2) un ordre spécifique pour le traitement des transmissions de données par liaison montante depuis le ou les terminaux (pour la liaison montante). La performance de chaque sous-hypothèse est ensuite évaluée (par exemple, sur la base d'une ou plusieurs mesures de performance). Une sous-hypothèse est ensuite sélectionnée pour chaque bande de fréquence sur la base de la performance évaluée, et le ou les terminaux de chaque sous-hypothèse évaluée sont ensuite programmés pour la transmission de données sur la bande de fréquence correspondante.
