Abstract: In a telecommunications network (10), a platform (34) is provided to perform authorization, routing, gathering, and delivery of transmissions between multiple remote units (12) and host locations (14). In a controlled environment, remote units (12) are authorized to initiate transmissions to and receive transmissions from a limited number of locations. The platform (34) stores profile information for remote units in a database (38), including services authorized for remote units (12) based on timing events. The platform (34) determines the appropriate destination for a transmission from a remote unit (12) based on the profile information stored in the dabase (38) and identifiers associated with the remote unit (12) and telecommunications router (16) serving the remote unit (12). The platform (34) authorizes a transmission to the destination based on the profile information, determines a routing number associated with the destination, and transmits the routing number to an appropriate point in the network (10) to enable completion of the transmission.

Abstract: A terrestrial repeater is disclosed for use in a satellite transmission system that may also include a plurality of satellites. The terrestrial repeaters are implemented as OFDM transmitters to minimize the channel impairments caused by multi-path propagation. The OFDM terrestrial repeaters differentially encode the transmitted signal over frequency, as opposed to time, in order to avoid channel phase distortion. The OFDM receiver allocates two unmodulated sub-carriers as pilot bins and thereby provides two sub-carriers as a reference within each OFDM symbol. At the OFDM  receiver, the two unmodulated pilot bins contain no phase information and provide a reference for the differential demodulation performed by the OFDM receiver.  The OFDM transmitter operates in two modes, namely, a normal mode and a transmitter identifier information (TII) mode. The TII mode contains all of the functions of the normal mode, and also transmits a repeater identification signal with the customer data, using the inactive OFDM sub-carriers (bins). In a normal mode, the OFDM  transmitter optionally fills unused (inactive) sub-carriers with zeroes and in a TII mode, the OFDM  transmitter uses at least some of the unused (inactive) sub-carriers to transmit the transmitter identifier information (TII). The predefined TII value is mapped onto a set of complex symbols. The TII signal facilitates the receiver test equipment in associating the received signal with the terrestrial repeater(s) that generate the TII signal.

Abstract: A method and apparatus for steering saw blades which includes an arbor rotatable about a rotation axis. Saw blades are mounted on the arbor in such a manner that the saw blades rotate with the arbor and are angularly adjustable in relation to the rotation axis of the arbor. A rigid guide assembly is provided having a plurality of guides each of which accommodate one the saw blades, such that movement of the guide assembly angularly adjusts the saw blades in unison. A leading edge of each of the saw blades is positioned along a common alignment plane. A support is provided for the guide assembly. The support has an underlying pivot axis spaced from, and substantially perpendicular to the rotational axis of the arbor. This pivot axis is on the alignment plane such that the leading edge of each of the saw blades remain positioned along the alignment plane as the guide assembly is pivoted to move the guide assembly to alter the angular positioning of the saw blades. The method and apparatus avoids having to accommodate lateral offset when the saw blades are in. an angular position.

Abstract: Cette invention se rapporte à un procédé et à un système de régulation de l'épaisseur d'une paire de dendrites dans un processus de croissance dendritique de membranes de silicium, en vue d'améliorer la production de membranes de silicium de type dendritique. A cet effet, une image de chaque dendrite d'une membrane sortant d'un bain de silicium fondu dans un four est produite par une paire de caméras focalisées sur la paire de dendrites. Les images des dendrites sont ensuite numérisées, l'épaisseur moyenne des dendrites est calculée et comparée à des paramètres servant de valeurs de consigne. La différence moyenne entre les épaisseurs des dendrites et les paramètres des valeurs de référence sert à réguler la température globale du four, alors que les différences entre l'épaisseur de chaque paire servent à réguler la distribution de température latérale du four, afin de maintenir l'épaisseur des dendrites à l'intérieur de limites prédéterminées. Ce procédé peut être utilisé dans une configuration en boucle fermée, en vue de réguler automatiquement la température du four et la distribution de température latérale, ou dans une configuration en boucle ouverte, en vue de fournir un retour d'information visible à l'opérateur qui règle manuellement les conditions de température du four.
