IPC: H04B10/272
Filed: 1996-09-20
Abstract: The optical amplifier combiner arrangement is used in a tree-like optical network (APON) consisting of the cascade connection of dedicated branches of the arrangement and of a common branch. The arrangement is coupled between a plurality of optical network users and on optical line terminator, viathe dedicated branches and the common branch respectively. The network enables upstream transmission of information signals from the optical network users to the optical line terminator. The optical amplifier combiner arrangementincludes for each branch of the dedicated branches: - an optical amplifier to amplify an information signal with a gain value and tothereby generate an amplified information signal with a predetermined power level, - an optical switch on/off coupled between the optical amplifier and an optical combiner to pass the amplified information signal when the information signal ispresent and to interrupt the branch when the information signal is not present The optical combiner is included in the arrangement to combine all amplified information signals according to a multiple access technique and to thereby generate an outgoing optical signal for application to the optical line terminator.

Inventor: VENKATESWAR VADLAMANNATI
IPC: H04N1/41
Filed: 1996-11-14
Abstract: A method for compressing screened image data for printing. The data is generated by tiling an image with multi-pixel cells. The pixels within any one cell may or may not be rescanned to be better fit for compression. The method allows for selection between two compression paths, one which has no loss (24), the other which is lossy (26). Once the data is compressed, the information is stored in a buffer (16), then sent to the exposure module. If the lossy scheme is selected, a quantization factor (14) is used in compression that may be adjusted, depending upon feedback signals (18,20), to increase or decrease the compression.

Title: Method and apparatus for testing a digital communication channel at variable or fixed data rates
Inventor: BAYLEY GWAIN
IPC: H04L69/40
Filed: 1995-11-29
Abstract: The invention provides a system and method for testing signal transmission quality wihin a digital communication system and may be incorporated within a digital cellular communication system in which information is exchanged over spread spectrum communication channels. A test sequence of digital data transmitted over the communication channel is received at a receiving station, within which is also generated a replica of the test sequence of digital data. The accuracy of transmission over the communication channel is then determined by comparing the replica of the test sequence of digital data to the test sequence of data received over the communication channel. The invention allows the test sequence of digital data to be transmitted at one of a set of known data rates, with the received station being disposed to identify the data rate associated with each test sequence of digital data. In order to simulate the transmission of, for example, voice data, the system may be configured such that each test sequence of digital data is generated in accordance with a pseudorandom process.

Abstract: L'heure est générée dans un radiotéléphone cellulaire par contrôle des changements du champ d'identification de concordance (REGID) des messages de service lorsque le champ REGID est incrémenté. L'utilisateur du radiotéléphone cellulaire doit indiquer l'heure et une valeur correspondante du champ REGID est obtenue, puis l'intervalle entre les mises à jour du champ REGID est déterminé. Lorsque l'on a besoin de savoir l'heure, une valeur actuelle du champ REGID est calculée et l'heure est calculée sur la base de l'heure indiquée par l'utilisateur, la différence entre les valeurs du champ REGID et l'intervalle entre les mises à jour. L'heure peut ainsi être générée dans des systèmes de radiotéléphones cellulaires qui ne transmettent pas l'heure sans qu'il soit nécessaire d'installer des puces d'horloge en temps réel dans le radiotéléphone cellulaire.

Abstract: The self-standing pallet stacking and dispensing unit has a U-shaped frame defining a pair of side walls and a rear wall.  A stack of empty article-carrying pallets is vertically installed between the frame walls.   A pair of fingers are pivoted on a carriage member vertically movable along the outer surface of each side wall.  The fingers can be pivoted between an inner pallet engaging position, in which they project inside the frame wall through slots located therein,  and an outer pallet clearing position, in which they are located entirely outside the frame wall.   The carriage member, along with the fingers, is movable between an upper and a lower position.  In use, the stack of pallets can be engaged by the fingers, either at its lowermost pallet or its second lowermost pallet, and lifted slightly above ground by the carriage members lifting the fingers in their common vertical displacement.  If the lowermost pallet is engaged, then an additional pallet may be inserted under the stack of pallets.  If the second lowermost pallet is engaged, then the lowermost pallet may be removed, free from the load of the overlying, spaced stack of pallets.

Abstract: A transceiver (5) for an asymmetric communication system such as asymmetric digital subscriber line (ADSL) includes a configuration register (71) defining operation at either a central office (CO) or a remote terminal (RT). The configuration register (71) includes a control bit (72) for selecting either CO or RT mode. The transceiver (5) includes a signal processing module (70) configured according to the state of the control bit (72). For example, a digital interface (70) converts transmit data into transmit symbols and converts received symbols into receive data. The digital interface (70) uses a large memory (158) as a buffer in the transmit path and a small memory (160) as a buffer in the receive path in CO mode. In RT mode, the digital interface (70) uses the small memory (160) in the transmit path and the large memory (158) in the receive path. The selective configuration allows a single integrated circuit to be used in both CO and RT equipment.

Abstract: L'invention se rapporte à un procédé de préparation d'un vaccin antigrippal de recombinaison par génie génétique. Le vaccin obtenu est un vaccin antigrippal polyvalent, de préférence trivalent, basé sur un mélange d'antigènes d'hémagglutinine de recombinaison clonés à partir de virus de la grippe ayant un potentiel épidémique. Les antigènes d'hémagglutinine de recombinaison sont des glycoprotéines (HA0) non clivées, entières, obtenues à partir de vecteurs d'expression du baculovirus dans des cultures cellulaires d'insectes et purifiées dans des conditions de non dénaturation. Selon le mode préféré de réalisation, les gènes clonés de l'hémagglutinine (HA) sont ensuite modifiés par délétion des séquences de peptides signaux hydrophobes naturels et sont remplacés par un nouveau peptide signal chitinase du baculovirus. L'invention se rapporte également de manière générale à l'extraction et à la purification effectives de la protéine de recombinaison de HA obtenue dans des cellules d'insectes ainsi qu'à la purification des protéines de rHA issues des virus de la grippe de sous-type A et de type B.
