Title: Method and apparatus for the management of data files
Inventor: BESSETTE LUC
IPC: G16H40/67
Filed: 1998-05-29
Granted: 2005-12-20
Abstract: The present invention provides a network system for storage of medical records. The records are stored in a database on a server. Each record includes two main parts, namely a collection of data elements containing information of medical nature for the certain individual, and a plurality of pointers providing addresses or remote locations where reside other medical data for that particular individual. Each record also includes a data element indicative of the basic type of medical data found at the location pointed to by a particular pointer. This arrangement permits a client workstation to download the record along with the set of pointers which link the client to the remotely stored files. The identification of the basic type of information that each pointer points to allows the physician to select the ones of interest and thus avoid downloading massive amounts of data where only part of that data is needed at that time. In addition, this record structure allows statistical queries to be effected without the necessity of accessing the data behind the pointers. For instance, a query can be built based on keys, one of which is the type of data that a pointer points to. The query can thus be performed solely on the basis of the pointers and the remaining information held in the record.

Abstract: A method and apparatus are provided for connection-oriented switching in a communications network wherein a pre-established path is established between a select pair of an ingress switch and an egress switch. The use of pre-established paths enables a reduction in the total number of connections required inside the switch cloud, reduces the CPU load on trunk switches, and shortens the time for connection setup. In the embodiment described, the DA/SA  fields of a MAC frame data packet are replaced with a "virtual path", which identifies the pre-established path between the ingress and egress switches. A  "virtual circuit" is provided in another field of the modified packet which specifies the out-port and out-header on the egress switch for demultiplexing the modified packet upon receipt at the egress switch. The virtual circuit is exchanged between the ingress and egress switches at connection setup. The virtual path is assumed to already be in place, and known to both switches, prior to connection setup.

Abstract: La présente invention se rapporte à un réseau ATM point à multipoint efficace, fonctionnant en hyperfréquences, qui comporte une station de base (BS 205) diffusant en continu par l'intermédiaire d'une antenne sectorielle (200). Ce réseau met en oeuvre un multiplexage temporel (TDM time division multiplexing) pour la transmission descendante et un accès multiple à répartition dans le temps (AMRT) pour la transmission ascendante. La transmission descendante est constituée de cellules ATM encapsulées dans des unités de données du protocole (PDU protocol data unit) de contrôle d'accès au support (MAC media access control) destinées à la correction des erreurs sans voie de retour (FEC forward error correction) et à la synchronisation. Les petits terminaux d'abonnés (ST small terminals), et notamment les unités radios des abonnés (SRU subscriber radio unit, 202), reçoivent la diffusion et la transmette à un système d'accès aux abonnés (SAS subscriber access system, 204) qui supprime les cellules ATM qui ne sont adressées qu'à ces petits terminaux. De façon à assurer une forte protection FEC et à maintenir le même débit de symboles que sur la transmission descendante sans sacrifier la largeur de bande, on utilise pour la transmission ascendante un procédé de modulation à code en treillis modifié, qui incorpore le codage Reed Solomon.
