Title: System og fremgangsmåte for posisjonsovervåkning ved bruk av ultralydsensor
Inventor: COONROD DONALD SCOTT
IPC: G01S15/88
Filed: 2014-09-19
Abstract: Det er beskrevet et ultrasonisk posisjonsavfølingssystem. I en utførelsesform innbefatter systemet en ultralydsensor innrettet for å overvåke posisjonen til en anordning. Systemet innbefatter også avstandsbestemmelseslogikk. Sensoren blir styrt av logikken for å rette en ultralydpuls mot anordningen. Logikken er innrettet for å beregne overføringstiden og hastigheten til ultralydpulsen. Basert på disse parameterne beregner logikken banelengden mellom sensoren og anordningen, som svarer til posisjonen av anordningen i forhold til sensoren. I ytterligere utførelsesformer, kan det ultrasoniske posisjonssystemet innbefatte flere sensorer i kommunikasjon med avstandsbestemmelseslogikken for å overvåke flere anordninger.

Title: Apparatus for closing wounds and/or aspirating their secretion or similar fluids by means of vacuum
Inventor: KILIAN FRANK
IPC: A61M1/00
Filed: 1995-03-10
Abstract: PCT No. PCT/EP95/00903 Sec. 371 Date Jan. 6, 1997 Sec. 102(e) Date Jan. 6, 1997 PCT Filed Mar. 10, 1995 PCT Pub. No. WO95/24230 PCT Pub. Date Sep. 14, 1995The subject of the invention is a suction draw off device which permits a drawing off by suction of secretion, blood or the like and a closure of a wound by means of vacuum. Thereby, the suction draw off device has a container (1) closable by means of a lid (2), a bag (3) with a tube (4) which can be placed in the container (1), a passage for the tube in the upper part of the container wall or in the lid for drawing of the secretion or the like into the bag (3) and an opening in the container wall or in the lid for generating a vacuum in the container (3). Thereby, the suction draw off device is so configured that it is closed in a vacuum-tight manner in the closed condition of the container (1), so that the secretion suction draw off device is operable independently of a vacuum pump unit after a vacuum has once been generated in the container (1). For the case of the drawing off of blood during an operation, the bag (3) advantageously has a membrane (28) by means of which air drawn into the bag (3) in the container (1) can be released.

Title: Method of and apparatus for obtaining an injectable preparation
Inventor: CHERIF CHEIKH ROLAND
IPC: A61M5/28
Filed: 1997-06-04
Abstract: A method comprising the following steps: preparing in a vacuum a dry form (18) of an active principle, as well as a liquid (22), and drawing this liquid into the dry form, by the action of the vacuum to obtain an injectable preparation. The device comprises a gastight syringe (19) to condition under vacuum the dry form, a reservoir (12) containing the liquid (22) and a cap (29) forming a connector between the syringe and the liquid reservoir, the injection needle (25) of the syringe being driven into the septum (24) of the cap (29). The invention enables a preparation which is directly injectable by an automatic rehydration step to be obtained; indeed, after activation, the extemporaneous preparation is automatic since the device elements move by themselves under the action of the liquid which is drawn by suction into the volume under vacuum containing the solid formulation (18).

Title: Verifiable electronic journal for a point of sale device and methods for using the same
Inventor: CONDE ALBERTO
IPC: G07G1/12
Filed: 1999-09-17
Abstract: A point of sale device having a verifiable electronic journal system which maintains an electronic journal file in lieu of using a journal print station. Transaction information is first stored in a non-volatile random access memory. A data signature is determined based on the contents of the random access memory for a journal. Both the transaction information and the data signature are transferred to the separate journal memory. The journal memory may, for example, reside on the point of sale terminal and tampering with the journal transaction information may be detected by reference to the data signature which is also transferred and maintained in the electronic journal file. Preferably, the data signature is encrypted such as by a shared key encryption scheme and the associated public key is also transferred and stored in the electronic journal file from the device, such as a fiscal base, which is tracking the transaction information as it is created. A hashing technique is preferably used so that a comparatively small NVRAM may be utilized to support generation of a transaction information set for an electronic journal file for a journal period. Accordingly, the data signature is an encrypted version of a message digest which is a running value reflecting the total of transaction information passed to the electronic journal file during a journal period.

Title: Process for making microcellular polyurethane elastomers
Inventor: HO DAVID J
IPC: C08G18/00
Filed: 1999-07-27
Abstract: Microcellular elastomers and a process for making them are disclosed. The process comprises reacting a resin component ("B" side) with an isocyanate-terminated prepolymer ("A" side). Pre-reacting the right proportion of chain extender into an "A" side that also includes a high-primary, low-unsaturation polyol is the key to making low-density (less than 0.5 g/cm3) microcellular elastomers while avoiding problems with poor processing or inferior physical properties. The process is easy to practice, and provides lighter, high-quality polyurethane products, including protective sports equipment, arm rests or steering wheels for the auto industry, and midsoles or shoe soles for footwear.

Title: Rejuvenation of refractory metal products
Inventor: AIMONE PAUL
IPC: H01L21/285
Filed: 2002-02-14
Abstract: Refractory metal products, such as tantalum on non-refractory conductive metal backings, e.g. copper, can be rejuvenated after metal consumption in selected zones by powder filling the zones and high energy heating at high scan speed to sinter the added powder, without complete melting of the powder fill, thus establishing a microstructure consistent with the balance of the reclaimed product and avoiding the separation of the copper backing and tantalum sputter plate. The rejuvenation method can be applied to non-mounted refractory metal products that are subject to non-uniform erosion, etching, chipping or other metal loss. The form of such refractory metal products can be as plate, rod, cylinder, block or other forms apart from sputter targets. The process can be applied to, for example, x-ray disks or targets (molybdenum plate on carbon backing).
