Title: System and method for radar-assisted catheter guidance and control
Inventor: SHACHAR YEHOSHUA
IPC: G01S13/88
Filed: 2004-10-20
Granted: 2012-03-13
Abstract: A Catheter Guidance Control and Imaging (CGCI) system whereby a magnetic tip attached to a surgical tool is detected, displayed and influenced positionally so as to allow diagnostic and therapeutic procedures to be performed is described. The tools that can be so equipped include catheters, guidewires, and secondary tools such as lasers and balloons. The magnetic tip performs two functions. First, it allows the position and orientation of the tip to be determined by using a radar system such as, for example, a radar range finder or radar imaging system. Incorporating the radar system allows the CGCI  apparatus to detect accurately the position, orientation and rotation of the surgical tool embedded in a patient during surgery. In one embodiment, the image generated by the radar is displayed with the operating room imagery equipment such as, for example, X-ray, Fluoroscopy, Ultrasound, MRI, CAT-Scan, PET-Scan, etc. In one embodiment, the image is synchronized with the aid of fiduciary markers located by a 6-Degrees of Freedom (6-DOF) sensor. The CGCI  apparatus combined with the radar and the 6-DOF sensor allows the tool tip to be pulled, pushed, turned, and forcefully held in the desired position by applying an appropriate magnetic field external to the patient's body. A  virtual representation of the magnetic tip serves as an operator control. This control possesses a one-to-one positional relationship with the magnetic tip inside the patient's body. Additionally, this control provides tactile feedback to the operator's hands in the appropriate axis or axes if the magnetic tip encounters an obstacle. The output of this control combined with the magnetic tip position and orientation feedback allows a servo system to control the external magnetic field.

Abstract: The present invention relates to a device (1) and a method for the preparation of data (21) to be sent as a continuous stream via a communication network. The device comprises means for obtainment (11) of the data originating from a database (2), which contains at least two data stream entities (Ej) for data associated respectively with different transmission throughputs (24), means of transfer (12) of these data to a sending system (3), means of connection (13) to one of these entities, and means of switching (14) of the means of connection from one of the entities to another. The preparation device also comprises means of regular addition (15) to the data transferred, of error correction codes (22). The means of switching switch from a first entity to a second entity of greater throughput, when this augmented data stream (DATA) reaches the sum of the sending throughput associated with the second entity and of an additional throughput (possibly zero) associated with an initial input of error correction codes of the second entity, and the means of addition reinitialize the addition of the codes to this initial input upon this switching. Application to streaming over IP network.

Title: Method for renovating a combined blast furnace and air/gas separation unit system
Inventor: DUBETTIER-GRENIER RICHARD
IPC: C21B5/00
Filed: 2005-02-11
Granted: 2012-09-04
Abstract: The invention relates to a method for renovating a combined system consisting of a blast furnace supplied with an oxidant fluid received at least partly from an air/gas separation unit (ASU). The inventive method consists in injecting, before renovation, at least 50 % of the flow rate of the blower feeding the blast furnace into an air/gas cryogenic separation unit in order to produce oxygen whose purity is greater than 90 % by volume of O2 which feeds the blast furnace, in controlling the blower airflow rate and the pressure of the air derived therefrom by means of a regulator which measures said flow rate and/or pressure at the input and/or output of a cleaning stage which is mounted upstream of the separation unit in such a way that the flow rate and pressure of the air derived from the blower is controlled. The fluid feeding the blast furnace consists of pure oxygen or diluted by air produced by the cryogenic separation unit.

Abstract: A process for the recovery of sulfur from an acid gas stream is disclosed. The process includes a Claus sulfur recovery step in combination with a biological sulfur recovery step to provide a sweet gas stream having very low concentrations of hydrogen sulfide and sulfur dioxide. The process includes reacting an acid gas steam with oxygen under such oxidation conditions to yield a combustion gas comprising hydrogen sulfide and sulfur dioxide so as to have a ratio of hydrogen sulfide to sulfur dioxide exceeding 2:1, preferably from 2:1 to 30:1. The combustion gas is reacted under Claus reaction conditions to yield a reaction gas comprising sulfur. Sulfur is recovered from the reaction gas to yield a tail gas comprising a concentration of hydrogen sulfide and less than 1000 ppm sulfur dioxide. The tail gas is contacted with a lean absorbent thereby remove from the tail gas a portion of the hydrogen sulfide contained therein and to yield a sweet gas and a rich solvent comprising dissolved hydrogen sulfide. The dissolved hydrogen sulfide of the rich solvent is biologically oxidized to elemental sulfur by contacting the rich solvent with sulfur bacteria under suitable biological oxidation conditions with the rich solvent.

Abstract: A light-weight display easel assembly for use with photographs and photographic greeting cards is described, wherein the display device is a substantially planar sheet or panel of paperboard or similar cellulose-containing material having a plurality of die-cut flaps thereon, each of the die-cut flaps having one scored edge which allows for the outward folding of the flap. The display easel further comprises a plurality of adhesive strips on the front face of the paperboard, for attachment of a photograph or photographic greeting card thereto. The display easel, once assembled, is lightweight enough such that it can be mailed without the need for excess postage fees. Additionally, due to the attachment of the display easel to substantially the entire back face of a photograph, the entire photograph is fully supported and is therefore resistant to creases, indentations, warping, and other damages which can occur during the mailing process.
