Abstract: Le système et le procédé de la présente invention permettent la vérification automatique des données de listages de programmmes dans une base de données de listages de programmation télévisuelle mise en oeuvre dans un système de guidage électronique concernant les programmes de télévision ("EPG"). La présente invention se rapporte à un système et à un procédé permettant la vérification des données EPG avant leur transmission à un système de télévision par câble ou autre système de télévision payante (ou bien avant leur transmission aux spectateurs). Ce système de vérification peut s'utiliser pour rechercher, dans la totalité de la base de donnée ou dans un sous-ensemble de celle-ci, défini par l'utilisateur, l'un ou plusieurs des éléments suivants: absence de stations, temps morts et chevauchements dans la programmmation, absence de titres, absence de copie, absence de rubriques, absence de classement des films, titres trop longs, copie trop longue, erreurs de rédaction, et langue impropre. De cette manière, le serveur EPG garantit l'intégrité des données EPG et réduit notablement le temps nécessaire à la vérification manuelle de toutes les données présentes dans la base de données de listages de programmes. Ce système de vérification peut être aisément intégré à d'autres étapes de traitement effectuées sur les données EPG avant leur transmission aux exploitants de télédiffusion multisystème et par câble.

Abstract: Growth factors and/or angiogenic factors are administered in combination with dissociated cells to be transplanted, preferably in microspheres with the cells on or in a polymeric matrix, to enhance survival and profileration of the transplanted cells. Examples demonstrate that epidermal growth factor (EGF) was incorporated into microspheres fabricated from a copolymer of lactic and glycolic acid using a double emulsion technique, the incorporated EGF was steadily released over one month in vitro, and it remained biologically active, as determined by its ability to stimulate DNA synthesis, division, and long-term survival of cultured hepatocytes. EGF-containing microspheres were mixed with a suspension of hepatocytes, seeded onto porous sponges, and implanted into the mesentery of two groups of Lewis rats, to demonstrate efficacy in vivo. Two weeks after implantation in PCS animals, devices which included EGF-containing microspheres showed a two-fold increase in the number of engrafted hepatocytes, as compared to implants which received blank microspheres.

Abstract: A rate sensor for sending applied rate on at least two and preferably three axes includes a vibrating structure (6).      Means are provided for vibrating the structure (6) in a Cos 2.theta. carrier mode at a Cost 26 frequency. This carrier mode provides the linear momentum components necessary to couple energy into response modes in every geometric plane.      Rotation about one or other of the axes in the plane of the vibrating structure will generate Coriolis forces which cause a rocking motion of the vibrating structure (6) about the same axis at the carrier mode frequency. The vibrating structure (6) has a substantially planar substantially ring or hoop like form shaped and dimensioned to match the frequencies of the Cos 2.theta. mode and rocking mode vibrations in the structure (6) resulting in a resonant amplification of the rocking made vibrations caused by rotations around axes in the plane of the structure (6). Rotation about the third axis normal to the plane of the structure (6) generates Coriolis forces which couple energy into the degenerate Cos 2.theta. response mode. The Cos 2.theta. response and rocking mode vibration amplitudes are proportional to the applied rate and means are provided for detecting the Cos 2.theta. response mode and rocking mode vibration and thereby the applied rate.

Abstract: Method for discriminating between an internal arc and a circuit opening arc detected in a device contained in a metallic envelope having at least a set of busbars(1) and a interrupter switch(2) and fitted with a protection system(4) and a computer(5). The method detects the appearance of the arc(c) by means of a sensor(8) which generates an arc apparition signal(c) and transmits this signal to the computer(5) and determines the time lapse T = t0 - ta between the reception instant t0 of a trigger command(o) for the switch(2) transmitted to the computer(5) and the start instant ta of the acquisition of this signal by the computer(5). If the time lapse T is positive, the arc is deduced to be an internal arc. If the time lapse T is negative and the absolute value is less than or equal to 10ms, the arc is deduced to be an internal arc. If the signal presents a rupture point in the 500ms following its acquisition start, the arc is deduced to be an internal arc. If the signal does not present a rupture point in the 500ms following its acquisition start, the arc is deduced to be an rupturing arc.

Abstract: Power control in a spread-spectrum communication system takes place by determining origination power of a traffic channel based on a number of active demodulators and pilot channel signal quality (610). Once origination transmit power is determined and call origination takes place, the transmit power is reduced at a first rate when a time is less than a time for all active demodulators to be established (615), otherwise the transmit power is reduced at a second rate (621). After all active demodulators have been acquired power control takes place by receiving a Power Measurement Report Message (PMRM) or a Pilot Strength Measurement Message (PSMM), determining a signal quality metric existing at the remote unit based on the PMRM or PSMM, and adjusting transmit power based on the signal quality metric (645).

Title: Apparatus for controlling internetwork communications
Inventor: SWALES ANDREW G
IPC: G05B19/418
Filed: 1998-09-09
Granted: 2007-06-19
Abstract: An interface allows for the transfer of real time control data with guarante ed delivery times between devices on a general purpose network and an industrial control system. A proxy server takes the role of a TCP/IP router and is configured to control the ra te at which messages are forwarded from the non-real time to the real time portion of the network , keeping the loading of the real time portion stable regardless of the external non-real t:ime communication demand. Real time data is preconfigured and exchanged in a regular sequence, with the cyclic update period known. The length of any communication message necessary to transmit this information, plus any sequencing and acknowledgment overhead, is calculated in advance and aggregated. Each device with authority to transmit on the shared medium is given a time budget, calculated so that the total transmission quantity in unit time is deliberately limited to some fraction of the maximum transmission capability of the network. All communications from devices whose traffic loadings cannot be so controlled are arranged to pass through the proxy device in order to gain access to the deterministic network, and the proxy enforces the budget limits by introducing deliberate delays to the request messages if necessary.
