Title: Single lumen access deployable ring for intralumenal anastomosis
Inventor: ORTIZ MARK S
IPC: A61B17/11
Filed: 2004-09-29
Granted: 2012-08-14
Abstract: Creating an anastomosis, or the surgical formation of a passage between two normally distinct vessels or lumens, is enhanced by an applier that introduces a ring device without the need for a separate anvil to form a hollow rivet shaped attachment. Moreover, the ring device may be advantageously formed in a cylindrical shape from molded polymer material or stamped from sheet metal with proximal and distal rings connected by proximal and distal arms that respectively form hinged, ring shaped so appose tissue walls. A center ring or portion sits in the attachment site. The applier causes actuating by moving the rings relative to one another. A latching mechanism locks the rings in the actuating state.

Abstract: An apparatus and method for use with a railroad dragging equipment detecting (DED) system (102) that detects objects hanging from and dragged beneath a train as the train travels along rails (108) of a railroad track (109). A generator (202) supplies a first signal and is coupled to a magnetic amplifier coil (132) to form a magnetically variable impedance circuit (200). The magnetic amplifier coil (132) is responsive to the first signal to create a circuit impedance in series with a detection circuit (210). A magnet (205) is mechanically connected to the cam/follower system (208) and is positioned near the magnetic amplifier core (206) for varying a circuit impedance of the detection circuit (210). A detection circuit (210) generates a second signal as a function of variations in circuit impedance. A controller (206) is responsive to the second signal for activating an alarm (128) when the magnet (205) moves relative to the magnetic amplifier coil (132).

IPC: H01Q5/35
Filed: 1999-12-01
Granted: 2007-02-13
Abstract: A monitoring system incorporates antennas that transmit signals at predetermined frequencies; the transmitted signals are received by tags located in the active monitoring area of the antenna which then transmit signals back to the antenna. The antennas are tuned to each desired frequency prior to driving the antennas to transmit at the desired frequency. The system transmits a range of frequencies in a sequence that uses overlapping frequency steps and incorporates an antenna system that employs digitally controlled, differentially driven, scanning transceivers, and walk through magnetic induction antennas positionable in various configurations to maximize detection of tags being transported through the antenna system. A carrier may be used to transport several frequency identification devices. The carrier includes at least one circuit having an antenna and a series capacitor for tuning the antenna. Enhanced interrogation and communication operations are provided when the tag carrying devices are placed in the carrier as the energy received in a first carrier pattern is re-radiated in a second pattern to improve transceiver communication without collision.

Title: Improved method for reverse transcription
Inventor: HAYASHIZAKI YOSHIHIDE
IPC: C12N15/10
Filed: 1997-07-24
Granted: 2010-11-23
Abstract: A method for preparing a cDNA from a mRNA using a reverse transcriptase wherein reverse transcription is performed at a temperature at which the mRNA does not take a secondary structure, for example, at a temperature of 45°C or more. The method is performed, for example, using a heat-labile reverse transcriptase in the presence of a substance exhibiting chaperone function having chaperone function such as saccharides. The method is performed, for example, in the presence of metal ions necessary for activation of the reverse transcriptase and a chelating agent for the metal ions such as a deoxynucleotide triphosphate. The method is capable of reverse transcription over the full length of mRNA template even if the mRNA is a long chain mRNA and, as a result, producing a full length cDNA.
