Title: Recepteur pour systeme de positionnement par satellites en presence de trajets d'ondes radioelectriques parasites
Inventor: SOUBIELLE JEROME
IPC: H04B1/707
Filed: 2000-11-17
Abstract: La présente invention concerne un récepteur pour système de positionnement par satellites en présence de trajets d'ondes radioélectriques parasites. Un satellite émettant une onde codée, le code formant le signal utile étant du type pseudo-aléatoire répétitif et modulant une onde porteuse, la distance du récepteur au satellite est déterminée par le temps de propagation (~) de l'onde du satellite au récepteur. Le récepteur mémorise et déroule une réplique du code selon un modèle. Le temps de propagation est estimé dans une boucle de poursuite de code comme étant le retard qui maximise une fonction d'intercorrélation entre le signal utile reçu par le récepteur selon un trajet direct depuis le satellite et la réplique du code du signal concerné. Le modèle du signal utile s(t) en entrée du récepteur est défini en fonction du temps t par: s(t)=A(t)c(t-~)e2.pi.jf d t + z(t)c(t - .theta.)e2.pi.jf d t + b(t) où: - A(t)c(t-~)e2.pi.jf d t modélise le signal direct du satellite au récepteur ; - z(t)c(t-.theta.)e2.pi.jf d t modélise un signal équivalent à des signaux parasites réfléchis par une surface ; - b(t) représente un bruit gaussien ; c(t) représentant le code et A(t) et z(t) ses amplitudes respectives pour le signal direct et pour le signal équivalent, f d représentant la fréquence Doppler du signal direct, ~ représentant le retard du signal direct et .theta. le retard du signal équivalent. L'invention s'applique notamment aux systèmes de type GPS ou équivalent lorsqu'un signal radioélectrique émis par un satellite se réfléchit sur une surface proche de l'antenne du récepteur, par exemple sur la surface terrestre, entraînant des erreurs de positionnement.

Inventor: OLIN THOMAS
IPC: C12Q1/48
Filed: 1999-04-16
Abstract: The present invention relates to methods for screening for substances which are activators or inhibitors of Protein kinase B (PKB) and can be used as a kinase substrate for PKB by the use of peptides comprising a specific sequence which do not include a large hydrophobic residue at the C-terminal end. These peptides can be used in assays measuring the activity of PKB, in screening for substances which are activators or inhibitors of gene transcriptional regulation of forkhead proteins through the catalytic activities of PKB and for discrimination between the effects of compounds which mediate insulin action through transcription from those which modulate activity of enzymes involved in metabolism by phosphorylation. The substrate peptide sequence comprises the sequence 1 ArgXaaArgXaaXaaSerXaa or sequence 2, in which, Xaa in position 2 is any amino acid, preferably chosen from Pro and Gly, Xaa in positions 4 and 5 are any amino acid, preferably chosen from Thr and Ser and Xaa in position 7 is any amino acid, preferably chosen from Asn, Gln, Thr, Ser and with the proviso that the sequence does not include a large hydrophobic residue directly C-terminal to the phosphorylation site.

Abstract: An information terminal incorporates a network interface and an extension interface, and in the case of outside call, an audio send signal is modulated into an audio signal frequency band, and sent to the exchange through a private telephone line and a subscriber's line by way of the network interface. An audio receive signal sent from the exchange through the subscriber's line and private telephone line is demodulated into an ordinary audio frequency band through the network interface.      On the other hand, in the case of extension service, an audio send signal is converted into a packetized digital signal by an extension interface circuit, and is further modulated into a higher frequency band so as not to overlap with the audio signal frequency band, and is transmitted through the private telephone line.

Abstract: A switching node (3) for providing admission control in a network comprises a number of separate priority queues (6) for receiving packets having differen t priority levels. Priority levels (1) to n provide guaranteed delay services,  priority levels n+1 to m provide guaranteed loss services, and priority leve l Pm+1 provides best effort service. Measuring means 51 to 5m continually measure the average bit rate entering each priority level buffer P1 to Pm, except the lowest Pm+1. When a request arrives with a kth priority level, th e network capacities for priority levels l=k..Pm are calculated. For all choic es of l, the measurements of traffic loads of levels l and higher are taken int o account. These capacity requirements are necessary to guarantee the quality of service for all flows already admitted to the lower priority queues. These capacities are compared to the network capacity, and if there is sufficient capacity, the request is accepted. Otherwise, the request is rejected.</SDOA B>

Abstract: An optical fiber communications system uses spread spectrum code division multiple access techniques to achieve better bandwidth utilization. A single  encoding mask having a first code is used to encode the optical signal. Ligh t, spatially encoded by the mask and temporally modulated with data, is transmitted over a fiber link and received by a decoder. A polarization insensitive separator splits the received light into two equal power components which are provided to two decoding masks used to decode the signa l. One of the masks has a second code identical to the first code and the other  mask has a third code complementary to the first code. The output light beam s filtered by the masks are differentially detected to generate an output signal, which is further processed for data recovery. The electrical signal is low pass filtered and electrically square law detected. The first codes are selected from a set of unipolar codes derived from a set of balanced bipolar  orthogonal codes. The codes may be either binary or analog.
