Abstract: L'invention concerne un procédé permettant d'immobiliser en même temps au moins deux biomolécules sur un substrat dans une proportion définie. Le procédé consiste à utiliser un copolymère conjugué à un nombre N de différents types d'oligonucléotides. Le copolymère peut être absorbé par la surface du substrat. N types d'oligonucléotides complémentaires des oligonucléotides liés aux copolymères peuvent être conjugués à N types de biomolécules. Les types d'oligonucléotides liés aux copolymères peuvent être mélangés dans une proportion définie, puis absorbés par la surface. Les oligonucléotides complémentaires liés aux biomolécules peuvent être conjugués aux oligonucléotides liés aux copolymères afin de créer un substrat sur lequel les biomolécules sont immobilisées en même temps dans une proportion définie. Cette invention concerne également un substrat préparé selon le procédé susmentionné.

Abstract: The end-plate assembly clamps an electrochemical cell or a stack of electrochemical cells with a polymer electrolyte membrane construction, in addition to forming the contact. An end plate (1) consisting of a synthetic material or metal, which is used to introduce the compressive forces into the cells or the cell stack, is provided. The end plate (1) is provided with a compensation layer (5) in the vicinity of the cell, which evens out the force introduction into the cell or the stack over the surface. The compensation layer (5) is covered with an electrically conductive layer (6), in order to form the electric connection (7) to the cell. The electrically conductive layer (6) is coupled to a connection (7) that is externally accessible. The compensation layer is formed by a material that is free-flowing under pressure, in such a way that it can be manipulated like a solid or pasty material during assembly, but takes on substantially liquid and thus excellent pressure distribution properties after the application of the clamping forces to the cell stack.

Abstract: A process is described in which an elastic fluid is contacted with a particulate solid. This comprises providing a substantially vertical elongate tubular containment zone (1) containing a charge of the particulate solid (5), the volume of the containment zone (1) being greater than the settled volume of the particulate solid (5). An upper retainer means (3) is mounted at the upper end of the containment zone (1), the upper retainer means (3) being permeable to the fluid but adapted to retain particulate solid (5) in the containment zone (1). A follower means (4) is movably mounted in the containment zone (1) beneath the charge of particulate solid (5) for movement upwardly from the lower end of the containment zone (1) upon upward flow of elastic fluid through the containment zone (1) at a rate beyond a threshold rate. In the process the elastic fluid is caused to flow upwardly through the containment zone (1) at a rate which is sufficient to cause particulate solid (5) to rise up towards the upper end of the containment zone and form a cushion of particulate solid (5) against the underside of the upper retainer means (3). The is rate is in excess of the threshold rate so as to cause the follower means (4) to move upwardly until it abuts against the underside of the cushion of particulate solid (5). The invention also provides an apparatus suitable for carrying out such a process and a method of loading a particulate solid into a substantially vertical tube.

IPC: H04B7/26
Filed: 2002-11-15
Abstract: A Wireless Communication Device (WCD) inter-operates with a Code Division Multiple Access (CDMA) communication system. The WCD operates in an idle mode wherein the WCD transitions between a sleep state to conserve power and an awake state to receive one or more paging signals. The WCD attempts to reacquire a first pilot signal associated with a first paging signal that was previously being demodulated, and a second pilot signal that was previously being tracked. The WCD performs a handoff from the first paging signal to a second paging signal associated with the second pilot signal when the attempt to reacquire the first pilot signal fails and the attempt to reacquire the second pilot signal is successful.

Abstract: Cette invention concerne un procédé de récupération de trames perdues transmises entre une unité d'émission de paquets de données et une unité de réception de paquets de données au sein d'un réseau de communication de données. Lorsqu'une trame est bien reçue par l'unité réceptrice de paquets de données, elle identifie des trames antérieures qui n'ont pas été reçues, soit au moins une trame avant la trame bien reçue. L'unité de réception de paquets de données entame une durée d'attente de rejet sélectif et détermine si le nombre de trames manquées jusqu'ici est supérieur ou égal à une valeur de seuil préétablie. Si tel est le cas, l'unité réceptrice de paquets de données génère un message de rejet sélectif avec charge utile indiquant la première trame manquée et les trames manquées ultérieurement. Si le nombre de trames manquées est inférieur à la valeur de seuil préétablie, l'unité réceptrice de paquets de données attend jusqu'à expiration de la durée d'attente de rejet sélectif, ou jusqu'au moment où le nombre de trames manquées est égal ou supérieur à la valeur de seuil préétablie. Elle envoie ensuite un message de rejet sélectif à l'unité émettrice de paquets de données. Après réception concluante des trames manquées retransmises par l'unité émettrice, l'unité réceptrice de paquets de données génère un message indiquant qu'elle est prête pour réception et transmet ledit message à l'unité émettrice.

Abstract: A method and system for an early warning detection of bioterrorism events is a website (40) along with associated database server (50) and a database (60) that includes obtaining temperature readings from a statistical sample of individuals in a community, and comparing the individual readings to one or more detection thresholds spaced apart by predetermined values with at least one of the thresholds being below the normally accepted temperature range defined as a low-grade fever. The comparison is then used to identify and evaluate a community's potential infection by a biological warfare agent so that early therapeutic action may be taken.
