Abstract: A method, system, and computer program by which a logical network connection can be maintained in the presence of disruption or failure of the underlying physical network connection. The technique defines a virtual connection between the client and gateway, which is not dependent upon continuous connectivity in the underlying physical connection, and can resume operation transparently even though the physical connection may be established on a different media type. Additionallv, the technique of the present invention enables the physical medium to be changed even though the physical connection was not disrupted. This change in medium may be based on a number of factors, such as quality of service or transmission speed, which can be monitored. A graphical user interface ("GUI") is defined whereby the human user may observe a depiction of the available physical connections and their status, information regarding the physical connection currently in use, etc. The user may initiate changes to the current physical connection from this GUI, without disrupting the logical connection.

IPC: G01S19/11
Filed: 1998-03-20
Abstract: Disclosed herein is a system for rapidly resolving position with centimeter-level accuracy for a mobile or stationary receiver (4).      This is achieved by estimating a set of parameters that are related to the integer cycle ambiguities which arise in tracking the carrier phase of satellite downlinks (5, 6). In the preferred embodiment, the technique involves a navigation receiver (4) simultaneously tracking transmissions (6) from Low Earth Orbit Satellites (LEOS) (2) together with transmissions (5) from GPS navigation satellites (1). The rapid change in the line-of-sight vectors from the receiver (4) to the LEO signal sources (2), due to the orbital motion of the LEOS, enables the resolution with integrity of the integer cycle ambiguities of the GPS signals (5) as well as parameters related to the integer cycle ambiguity on the LEOS signals (6). These parameters, once identified, enable real-time centimeter-level positioning of the receiver (4).

Title: Dispositif de soudage multi-faisceaux double intensite
Inventor: HSU CHEN-JEN REY
IPC: B23K26/03
Filed: 1998-05-13
Abstract: Cette invention se rapporte à un dispositif de soudage conçu pour souder l'une à l'autre une première et une seconde feuille de matière, lesdites feuilles possédant des profils différents les uns des autres. Ledit dispositif met en oeuvre une source d'énergie, par exemple un laser, pour produire un faisceau primaire d'énergie qui se propage en direction d'un élément de focalisation et d'un diviseur de faisceau. Ce dernier est composé de miroirs à échelons qui facilitent le réglage de la distance entre les faisceaux. On peut régler cette distance en fonction de la largeur de l'espace existant entre les feuilles à souder. Les faisceaux de soudage qui frappent respectivement l'une des feuilles à souder présentent une intensité caractéristique qui est sensible à l'épaisseur des feuilles. La feuille la plus épaisse est par conséquent soumise à un faisceau d'intensité supérieure de façon à assurer une pénétration suffisante pour effectuer un bon soudage en continu. On dispose d'une ou de plusieurs sources de chaleur pour préchauffer les feuilles de matière et pour provoquer une dilatation thermique qui permet de combler l'espace entre les feuilles. On peut en outre disposer d'un dispositif de contrôle qui permet de commander la mise au point des faisceaux d'énergie sur les matières à souder ainsi que les distances entre les faisceaux, en fonction de la largeur de l'espace existant entre les matières à souder.

Abstract: A towed body yaw angle sensor arrangement used to sense the angle between the axis of a tow fish and the flow of water. The water flow vector is used as the reference for correcting towed body yaw so that a magnetic compass in the towed body is aligned with the towed arrays streaming in the water flow. A yaw angle in the towed body with respect to the flow will cause errors for target bearing and skew the arrays relative to each other which will also cause errors. The flow sensor must be in the free flow off the towed body and ideally the sensing part is aligned with water current flow.      Also provided is a method for sensing and correcting a yaw angle.
