Title: A maneuverable electrophysiology catheter for percutaneous or intraoperative ablation of cardiac arrhythmias
Inventor: WARE DAVID L
IPC: A61B17/00
Filed: 1996-08-19
Abstract: A catheter (22) capable of both sensing myocardial electrical activity and delivering ablating energy within myocardial tissue, is disclosed. The catheter (22) comprises electrodes (38, 39) on the outer sheath and contains a movable fiber optic cable (42) that can be percutaneously advanced beyond the catheter body (22), and into the myocardium for myocardial heating and coagulation, or modification of tissues responsible for cardiac arrhythmias.  The fiber optic tip (42) is designed to diffuse ablating energy radially to ablate a larger volume of tissue than is possible with a bare fiber optic tip.  In addition, the tip is treated so that energy is not propagated in a forward direction, thus helping to prevent unwanted perforation of the heart tissue.  Also disclosed is a method of cardio-protection from ischemia comprising inducing local hyperthermia in heart tissue.

Patent CA-2230644-A1 (CA)
Inventor: MACIOSZEK JERZY A
IPC: G01N33/569
Filed: 1996-08-09
Abstract: La présente invention concerne un procédé de traitement d'échantillons biologiques, par exemple des sérums ou des plasmas humains, soupçonnés de contenir des facteurs rhumatoïdes, procédé servant à éliminer la réactivité croisée et les faux résultats positifs de dosages immunologiques d'IgM provoqués par la présence de facteurs rhumatoïdes dans ces échantillons biologiques. Selon un aspect de l'invention, le procédé comprend la dilution d'un échantillon biologique avec une quantité suffisante de tampon de neutralisation des facteurs rhumatoïdes pour obtenir que le pH des mélanges de réaction qui en résultent, contenant cet échantillon et une matière en phase solide, soit suffisamment bas pour qu'il en résulte une baisse d'affinité des facteurs rhumatoïdes de ces mélanges pour les anticorps d'IgG dans une mesure telle qu'ils ne forment pas de complexe avec des anticorps d'IgG liés à la matière en phase solide, ce qui facilite l'élimination de ces facteurs rhumatoïdes dans les mélanges avant la phase de détection d'un dosage diagnostique. Selon un autre aspect de l'invention, le procédé comprend l'introduction, dans une matière en phase solide contenant un complexe d'un élément liant et d'un anticorps, d'une quantité suffisante d'un tampon de neutralisation des facteurs rhumatoïdes dont le pH est assez bas pour que les facteurs rhumatoïdes liés à des anticorps d'IgG liés à la matière en phase solide réduisent leur affinité pour les anticorps d'IgG dans une mesure telle que les facteurs rhumatoïdes puissent être éliminés de la matière en phase solide par lavage, avant la phase de détection d'un dosage diagnostique. Pour ces deux aspects de l'invention, les classes de tampons qui conviennent pour le procédé selon l'invention comprennent des tampons ioniques, non ioniques et zwitterioniques dont le pKa ne dépasse pas environ 6,5. Comme exemples représentatifs de tampons qui conviennent pour le procédé de l'invention figurent, mais sans que l'invention se limite à eux, les acides acétique, citrique et formique et la glycine.

Title: Dynamic extension of static device drivers
Inventor: SWANBERG RANDAL CRAIG
IPC: G06F13/10
Filed: 1998-03-13
Abstract: A method of changing the functionality of a statically bound device driver, by dynamically extending the static device driver using a registered driver extension. The static device driver has a plurality of handlers or functions (such as input/output functions) used to control a device that is connected to or part of the computer system, and the driver extension modifies at least one of these functions, although it can be used to change several, or even all, of the functions. In the embodiment wherein the computer system is a UNIX-type workstation having a kernel residing in the memory, the static device driver is loaded in the kernel and is dynamically extended by providing at least one entry point for the driver extension.

Title: Pre-assembled electrical panel bonding screw
Inventor: BOZZONE CHRISTOPHER J
IPC: H02B1/16
Filed: 1998-03-25
Abstract: A bonding screw is pre-assembled in a distribution panel in a non-bonding position that does not bond a neutral bar within the panel enclosure to the enclosure wall. This allows an installer of the panel to select between the option of maintaining the bonding screw in the pre-assembled non-bonding position and the option of positioning the bonding screw from non-bonding position to a bonding position. A basepan is disposed within the enclosure between the neutral bar and the enclosure's back wall. The non-bonding position is defined by the screw shank thread having a threaded engagement with a through-hole in a basepan, the head of the bonding screw being spaced from the neutral bar, and the shank of the bonding screw being spaced from the enclosure's back wall. The bonding position is defined by the head of the electrically conductive part being disposed against the neutral bar and the shank being threaded into an extruded hole in the enclosure's back wall.

Abstract: A variable bore ram packer designed for use in a standard ram-type blowout preventer used in oil and gas drilling operations is disclosed. The variable bore ram packer includes top and bottom second plates having a central semi-circular opening which is sized to fit closely about the largest diameter pipe the variable bore ram packer will seal against. Anti-extrusion plates having a smaller central arcuate opening sized to fit closely the smallest diameter pipe the variable bore ram packer will seal are attached to the underside of the top plate by guide screws. The guide screws extend through slots in the top plates which control the motion of the guide screws and hence the anti-extrusion plates as the anti-extrusion plates move and seat against different diameter tubular members. A packer member of elastomeric material having a central semi-circular opening sized to fit closely the smallest diameter pipe the variable bore ram packer will seal is molded between the top plate and anti-extrusion plates and lower plate to form a unitary structure. A radially disposed cavity is molded in the packer adjacent the anti-extrusion plates to minimize damage to the packer as it moves radially and seals against different diameter tubular members.

Title: Razor with in situ sensor
Inventor: ORLOFF GLENNIS J
IPC: B26B21/22
Filed: 1998-09-04
Abstract: A wet shave shaving system which contains an in situ sensor within the razor cartridge or razor handle. The sensor preferably comprises either a piezoelectric or a piezoresistive material which produces an electrical signal or resistance change when it is strained. In an active feedback system, the signal would be transferred from the cartridge to the razor handle where an electronically-active actuator would extend or retract as necessary to position the cartridge to produce a shave with a constant shave force. In a passive feedback system, the signal would be transferred from the cartridge to the handle where an electronically-activated element, such as an indicator light, would be activated to produce an indication to the user that he or she should reposition the razor to produce a constant shave force. In an alternative embodiment, the passive feedback system signal would provide an indication to the user that the blades are worn and the cartridge or razor should be replaced.

Filed: 1997-06-17
Abstract: A request for call forwarding activation along with forward-to-number is received from a mobile station via one of the data channels such as a Stand-alone Dedicated Control Channel (SDCCH). The activation request itself is transported by an Unstructured Supplementary Service Data (USSD) message. The serving mobile switching center (MSC) analyzes the forward-to-number and establishes a speech connection with the mobile station by calling back the mobile station. Next, the MSC originates an outgoing call towards the forward-to-number and, as a result, establishes a speech connection between the mobile station and the telephone terminal associated with the forward-to-number. By establishing a speech connection between the two parties, the mobile subscriber requesting the call forwarding activation can verbally verify the forward-to-number. As an alternative, TCAP messages can be communicated between the serving MSC and the local exchange serving the forward-to-number to request the local exchange to verify the validity of the forward-to-number.
