Patent CA-2275892-A1 (CA)
Inventor: DAVIS BRIAN
IPC: C12N5/10
Filed: 1997-12-20
Abstract: Disclosed are compositions for incorporating nucleic acid into a cell.  Transgene constructs that include a desired nucleic acid sequence of interest may be injected into a cell together with a protein to provide site specific or random incorporation of the nucleic acid sequence into the chromosomal DNA  of the cell. The transgene construct and the protein are included in the described compositions together, with the protein facilitating the incorporation of the nucleic acid sequence of interest within the transgene construct, directly into the nucleic acid of a cell in a site-specific manner.  In other embodiments, the compositions include a transgene construct and an expression construct, the expression construct including a nucleic acid sequence that encodes an enzyme capable of facilitating the incorporation of the transgene sequence of interest into a cell. The invention further includes methods for incorporating a foreign nucleic acid into a cell employing a microinjection method. In particular embodiments, the method may be employed to introduce foreign nucleic acid into cells that grow in a non-adherent state. In these applications, the cells are immobilized onto a substrate surface that includes an adherent molecule, such as fibronectin.  Alternatively, the cells may be stabilized sufficiently to permit microinjection using holding pipettes or through the stimulation of the cells themselves to express molecules on their surface which bind chemical entities included at the surface of a culture plate.

Title: Communications module based repeater
Inventor: YORK TED H
IPC: H04L12/56
Filed: 1998-03-26
Abstract: A repeater communications module (RCM) (12) that enhances signals in a communications network comprises a processor (12-8) coupled to a communications medium and optionally to a host application ( 10).  The RCM (12) operates in one of two modes: (1) interface or host application controlled, and (2) standalone. In the interface mode, the RCM (12) receives packets from a host application (10), modifies the packets and transmits message packets in accordance with a transmit role table (TRT). In standalone mode, the RCM (12) initiates packets and transmits message packets in accordance with the TRT. All RCMs can be configured to repeat message packets which are received from the communications medium in accordance with a repeater role table (RRT). The RCM (12) includes a memory that stores the TRT and RRT. The TRT comprises a plurality of entries, and each entry comprises a destination house code, a destination device address, and a transmit repeater role identifier (TRRI). The processor (12-8) is programmed to compare a first field within a packet to the destination house codes in the TRT, and to compare a second field within the packet to the destination device addresses in the TRT, and to copy the TRRI corresponding to the TRT entry having a matching destination house code and destination device address to an RRI field in the packet, and then to transmit the packet onto the communications medium. The message packet will either be received and re-transmitted by a repeater (12) or received directly by the destination device (14).

Patent CA-2295990-A1 (CA)
Inventor: NORSTROEM HANS
IPC: H01L21/331
Filed: 1998-07-13
Abstract: L'invention concerne un transistor bipolaire du type NPN ayant une région active à la surface du composant, autour duquel on voit, le long de la surface, une configuration classique de zones à couche d'oxyde épais (18). La région active est partiellement recouverte d'une couche d'isolement en surface, comprenant de préférence une couche de nitrure (34). Une région tenant lieu de base dans la région active est matérialisée par une ouverture en forme de caisson, réalisée en procédé lithographique, dans la couche d'isolement en surface. S'agissant d'un transistor latéral bipolaire du type NPN sur lequel ce sont plutôt les régions émetteur et collecteur que l'on entoure de telles zones à couche d'oxyde épais, il est possible de définir lesdites régions d'une manière correspondante, en procédé lithographique, sous la forme d'ouvertures dans une couche d'isolement en surface. Dans les cas considérés, la présence d'ouvertures en forme de caisson permet de réduire la capacité de la jonction base-collecteur et celle de la jonction émetteur-collecteur, ce qui améliore les caractéristiques haute fréquence des transistors. Parallèlement, on utilise une région de la couche de nitrure de silicium (34) comme diélectrique efficace dans un condensateur fabriqué simulltanément. Il est possible d'ajouter au transistor du type NPN un fin cordon latéral d'isolement en nitrure entre une connexion de l'émetteur et une connexion de la base. Sur la même plaquette en semiconducteur, il est possible de réaliser des bornes de connexion au substrat, de type spécial, profond et étroit, de manière à assurer l'isolement des régions du composant. Pour isoler ces composants, on peut utiliser des tranchées (22), lesquelles peuvent avoir au niveau de leurs parois latérales un laminé dont le fond est un oxyde (23) et la partie supérieure un nitrure (25), de manière à faciliter l'attaque liée au procédé planar et pour constituer une barrière de diffusion.

Title: Improvements relating to injection devices
Inventor: WEEKES STUART
IPC: A61M5/20
Filed: 1998-08-20
Abstract: An injection device is disposable, and is designed to have a re-usable firing mechanism (37) fitted to its rear end. A syringe carrier (25) within the barrel (1) of the device is initially locked in a position with the needle (23A) of the syringe (21) retracted by a locking element (34) inserted laterally through the barrel (1). This element (34) also holds an axially movable connector (4) to which the firing mechanism connects. The device is made operable by removal of the locking element (34), and after use a return spring (30) ensures that neither the syringe carrier (25) nor the connector (4) assume positions where the locking element (34) can be re-inserted. An adaptor (40) may provided to facilitate preparing a syringe (22) with a two component dose, and for disposal after use the adaptor with an empty vial (41) still attached can be fitted to the rear end of the injection device in place of the firing mechanism (37).
