Title: Procede d'emission de donnees sur la partie visible d'un signal video
Inventor: CHUPP CHRISTOPHER ERIC
IPC: H04B15/00
Filed: 1999-07-14
Abstract: L'invention concerne un procédé permettant de coder des données (21) dans la partie visible d'un signal vidéo émis (11), sans toutefois altérer l'affichage d'un signal vidéo reçu. Ce procédé permet également de décoder (11) les données contenues dans ce signal vidéo reçu (13). Ce procédé consiste tout d'abord à associer chaque groupe de bits utiles destiné à être émis, correspondant à un symbole de données (21), à une séquence d'éléments faisant partie de plusieurs séquences d'éléments plus longues prédéfinies (23), chacune de ces séquences étant divisée en une multiplicité de lignes d'éléments (23). Ce procédé consiste ensuite à imbriquer chaque ligne d'éléments et son opposé, par paires, de manière à former plusieurs paires de lignes et ainsi à détecter les lignes d'éléments que celles-ci représentent. Le procédé de cette invention consiste en outre à mettre en corrélation chaque séquence d'éléments avec une ligne d'éléments détectée, afin de calculer une magnitude de corrélation, la séquence d'éléments présentant la magnitude de corrélation la plus élevée étant finalement désignée comme la séquence d'éléments dont le symbole de données a été émis.

Title: Preserving consistency of passively-replicated non-deterministic objects
Inventor: HALLMARK GARY
IPC: G06F11/14
Filed: 2000-12-21
Abstract: Techniques are provided for executing an operation in which a client invokes a replicated object. According to one technique, a primary replica of a replicated object receives a first request from a client, wherein the first request includes a request identifier. Rather than immediately attempting to process the request, the primary replica determines whether a record exists that corresponds to the request identifier. If a record exists that corresponds to the request identifier, then the primary replica responds to the first request with a reply associated with the record. If no record exists that corresponds to the request identifier, then the primary replica performs the steps of: starting a transaction; as part of the transaction, processing the request; as part of the transaction, storing a record associated with the request identifier and a reply to the request; committing the transaction; and delivering the reply to the client. The client may itself be a replicated object. If the client is nondeterministic, then the transaction initiated by the primary replica may be a nested transaction relative to a transaction executed by the client, or be executed as part of the same transaction as the client. If the transaction executed by the primary replica is executed as part of the same transaction as the client, then a savepoint may be established before the primary replica processes the request, so that a failure will not necessarily require all processing performed by the client to be rolled back.

Title: Method of surface treatment for stainless steel product for fuel cell
Inventor: OHTANI TERUYUKI
IPC: C23C26/00
Filed: 2001-11-06
Abstract: A method for treating the surface of a stainless steel product for a fuel cell containing, in wt%, 0.15% or less of C,17 to 36% of Cr, 0.005 to 3.5% of B, which comprises the first step of forming in advance a passive film with an oxidizing acid on the surface of the stainless steel product, the second step of allowing an aqueous acid solution to corrode the passive film, to thereby project one or more of a M23C6 type carbide, a M23(C, B)6 type borocarbide and M2B type boride, which are inclusions having good electroconductivity, the third step of forming a passive coating film with an oxidizing acid on the surface of the steel product except that of the inclusion above projected, and the fourth step of washing with water and drying. The method of treatment allows, without the use of a method requiring a high cost such as gold plating, the improvement in the contact resistance of the stainless steel product for a fuel cell, which results in the retention of excellent characteristics of a stainless steel product over a long period of time.

Abstract: L'invention concerne un article d'absorption de menstrues, tel qu'une serviette hygiénique, conçu pour être porté avec un sous-vêtement du type string ou g-string et fixé à celui-ci. En général, les articles absorbants destinés à être portés avec un sous vêtement et fixés à celui-ci devraient être conçus de manière à suivre la forme dudit sous-vêtement auquel ils sont fixés. Dans le cas d'un string, la serviette hygiénique ou le protège-slip possède une extrémité avant plus large, et une extrémité arrière plus étroite, ou peut être de forme triangulaire ou trapézoïdale. Selon l'invention, l'article absorbant en forme de lanière présente une construction dans laquelle le type et la quantité de matériau d'absorption de menstrues en forme de lanière, en particulier pour la partie centrale absorbante et la construction de l'article, est sélectionné de sorte que la résistance de l'article en flexion reste en dessous d'une valeur critique. Du fait des conditions d'utilisation intimes d'un string, la serviette hygiénique de l'invention se porte à proximité immédiate du contour du corps de la femme, ce qui permet une absorption à la source, et laisse peu d'espace, le cas échéant, pour une fuite de liquide. Les articles construits conformément à cette invention présentent une performance d'absorption et de fuite, lorsqu'on les utilise, qui surpasse même celle des articles possédant une quantité de matériau absorbant sensiblement plus élevée.
