Inventor: BACUS JAMES W
IPC: G01N15/14
Filed: 1990-02-23
Abstract: An image processing method and apparatus (10) determines a proliferation index of a cell sample by staining the cells with a chromogen for a proliferation substance and a counterstain for the cell nuclei. The chromogen is activated by an antibody-enzyme conjugate which binds to the proliferation substance to produce a stained cell sample. The stained cell sample is examined with an optical microscope (12), forming a portion of the apparatus, which produces a magnified cell sample image. The apparatus optically filters (18) the cell sample image and produces a pair of optically enhanced proliferation substance and cell nuclei images. The enhanced images are electronically analyzed to determine the amounts of cell nuclei and proliferation substance appearing in the images, respectively. The amounts are then compared to yield a proliferation index for the portion of the cell sample appearing in the cell sample image.

Title: Method of controlling turn-off current-converter switches of a bridge arm of a voltage-source converter
Inventor: MARQUARDT RAINER
IPC: H02M7/521
Filed: 1991-07-08
Abstract: ABSTRACT OF THE DISCLOSURE      A method and device control turn-off current-converter switches (V1, V2) of a bridge arm (6) of a voltage source converter (4).  The turn-off current-converter switches alternately turn on and off in response to control signals (AV1', AV2') generated by a controller (14, 16).  In accordance with the invention, portions of the generated control signals (AV1', AV2') standing by are cut out as a function of the load-current actual value (iLx) in relation to two load-current limiting values (I1, I2), which results in new control signals (AV1, AV2) for the turn-off current-converter switches (V1, V2).  A failure of the turn-off current-converter switches (V1 or V2) to turn off due to excessively high junction temperatures thus cannot cause a short circuit of the converter (4) on its dc voltage side.

Title: Twist and tuck freezer bag
Inventor: IELMINI ANGELO
IPC: B65D33/24
Filed: 1991-07-26
Abstract: TWIST AND TUCK FREEZER BAG                   ABSTRACT OF THE DISCLOSURE         A reusable bag for storing items.  The bag has a band located over at least part of the bag's outer surface.  The band is detachably secured to the bag with an adhesive.  To reseal the bag after opening, the band is partially lifted away from the bag.  A space is thus created between the band and the bag into which the twisted end of the bag may be inserted and secured.  The band contains adhesive on only a center region of the band to permit the band to be easily separated from the bag and so that user contact with the band does leave adhesive on the user's fingers or wear adhesive from the band.

Title: Test system viewer for fluorescence evaluation
Inventor: CHADWICK DAVID E
IPC: G01N21/64
Filed: 1991-09-17
Abstract: ABSTRACT    A test system viewer for fluorescence evaluation has been designed to facilitate the simultaneous evaluation of multiple test samples,  to provide  consistency  in the process for the evaluation of the fluorescence and to protect the operator from the harmful effects of the ultraviolet radiation associated with the viewer.    The viewer contains a base and a viewing shield, with the base having the  fluorescent  light  source  and  an internal  fluorescent  standard.    The  viewing  shield contains an internal ledge and a viewing area with a fixed viewing angle to the internal fluorescent standard.  The internal ledge and the viewing angle cooperate to block ultraviolet rays from the fluorescent light source and to prevent the  operator  from directly viewing the light source during operation of the viewer.  The use of a fixed light source, internal standard, viewing area and viewing angle   insures   observation   consistency   during  the evaluation procedure.

Abstract: P.F. 1690                                      PATENT                      ABSTRACT    A multilumen catheter having a distal portion with a soft tip and reduced cross-section.  The multilumen catheter of the present invention includes a flexible, elongated first catheter tube and a flexible,  elongated,  dual-lumen catheter tube which has  first  and second lumens  integrally formed and is disposed within  the  first  catheter  tube.   The  cross-section  of  the dual-lumen  catheter  tube  is  smaller  than  that  of  the  first catheter  tube  and  therefore,  an  independent,  single  lumen  is defined  in  the space between the first catheter  tube and  the dual-lumen catheter tube.  The dual-lumen catheter tube extends beyond  the  distal  end  of  the  first catheter  tube  thereby providing an overall reduced cross-section of the distal portion of the present multilumen catheter.  Furthermore, the dual-lumen catheter tube may be formed from a softer material than that of the  first  catheter tube  thereby  providing  a  softer  distal portion of  the present multilumen catheter.   A protective hub encapsulates  and  secures  the  proximal  ends  of  the  first  and dual-lumen catheter  tubes,  and  facilitates  fluid communication between each of the lumens and fluid transfer devices.

Title: Method and apparatus for high-speed bi-cmos differential amplifier with controlled output voltage swing
Inventor: REED JOHN A
IPC: H03F3/72
Filed: 1991-12-12
Abstract: The present invention provides apparatus and methods to achieve a high speed bi-CMOS differential amplifier with controlled output voltage swing for use in amplifying low level complementary logic signals.  The differential amplifier iscomprised of a load current controller and a sense amplifier. The load current controller compares a desired reference voltage to the voltage drop across a simulated load. The load current controller then produces therefrom a bias voltage corresponding to the current which results in a voltage drop equal to the reference voltage. The bias voltage, when applied to the sense amplifier, limits the output of the sense amplifier to a controlled voltage swing of magnitude equal to the reference voltage.

Patent CA-2065972-A1 (CA)
Inventor: CHIRIFE RAUL
IPC: A61N1/365
Filed: 1992-04-14
Abstract: A novel rate responsive pacemaker using isovolumic contraction time (IVCT) as a control signal responsive to metabolic demands is disclosed. This control signal is injected into the timing circuit of a standard rate adaptive pacemaker to enhance the pacer's ability to respond in direct relation to the patient's changing metabolic needs as he performs his daily activities.      A typical configuration using either right or left heart IVCT for rate control is described, in which the pacing rate is determined by the duration of IVCT. Since pacing rate and IVCT are linearly related, a simple conversion factor can be used to transform the duration of IVCT into the duration of the pacemaker escape interval (pacing rate). Although both right and left heart IVCT could be used for rate control, for the sake of simplicity only the right heart parameters are described herein.      The device is capable of operating in most of the available modes (WIR, DDDR, DDIR, AAIR), and has provisions for multiprogrammability, data storage, bidirectional telemetry, among other standard functions. The device has two inputs to measure IVCT: one, signaling the onset of mechanical activation of the ventricle (start of IVCT), and another, signaling the onset of ejection (end of IVCT). The time interval between these two signals is the duration of IVCT, which is processed by the pacemaker to determine the escape interval, through a simple conversion algorithm, analogous to what is available in the prior art. Onset and end points of IVCT are detected by any combination of biological sensors in the form of pressure, volume or flow transducers.
