Patent CA-2189754-A1 (CA)
Inventor: BRAIG JAMES R
IPC: A61B5/00
Filed: 1995-05-22
Abstract: A method and apparatus for monitoring glucose, ethyl alcohol and other blood constituents in a noninvasive manner. The measurements are made by monitoring infrared absorption of the desired blood constituent in the long infrared wavelength range where the blood constituent has a strong and distinguishable absorption spectrum. The long wavelength infrared energy emitted by the person as heat is monitored and the infrared absorption of particular constituents in the blood (such as glucose or blood alcohol) is measured by infrared detector (412) at characteristic infrared absorption wavelengths for those constituents. The measurements are preferably synchronized with systole and diastole of the cardiac cycle monitored by cardiac monitor (718) so that the signal contribution caused by veins and tissues (which do not pulse) may be cancelled by (418) when a ratio of the detected signals is taken. The concentration of the blood constituents is then determined in accordance with a polynomial equation.

IPC: C12N15/87
Filed: 1995-06-05
Abstract: Methods for increasing the efficiency of transduction of cells, including non-dividing cells, by recombinant AAV vectors. The methods utilize agents that alter certain aspects of DNA metabolism, more specifically, that affect DNA synthesis and or affect repair, that impact on maintenance of chromosomal integrity and or that cause damage to the cellular DNA. Agents and vectors can now also be preselected and screened for transducing ability and or transducing agents for their effect on DNA metabolism.

Patent CA-2195159-A1 (CA)
Inventor: FORNO JOANN
IPC: A61L2/26
Filed: 1997-01-15
Abstract: A system and method for handling contaminated operating room surgical instruments includes a rectangular porous strainer which is sufficiently large to fully contain a variety of surgical tools and instruments and a waterproof rectangular basin, sized to receive the strainer.  The basin is adapted to fit stably onto a conventional surgical ring stand either alone, or with a separate adapter.  The system replaces conventional round surgical basins which are not capable of safely containing the larger or longer surgical instruments typical of many modern surgical procedures.          Utilizing the system eliminates the current practice of manually transferring contaminated instruments  from the  round surgical basins  into  larger  soaking  trays  for  transportation  to  the decontamination area.

Particulièrement, dans l'une des concrétisations de la présente invention, une première partie d'un signal est codée avec un premier code pour produire une première partie de signal codé. Cette première partie de signal codé est ensuite transmise à un premier niveau de puissance. Ensuite, des données paramétriques sont reçues, ces données représentant une ou plusieurs caractéristiques d'une portion de signal reçu par le récepteur, cette portion de signal reçu ayant été basée sur la première portion de signal codé émise. Un second code et un second niveau de puissance sont ensuite déterminés d'après les données paramétriques reçues et une seconde portion du signal est codée avec le second code pour produire une seconde partie de signal codé. Finalement, la seconde partie de signal codé est transmise au second niveau de puissance.

Inventor: SMITH GARY A
IPC: G05B13/02
Filed: 1995-09-28
Abstract: A control system and method for providing a non-linear response for a single input-single output system. A system output is measured and compared against a predetermined set point. An error signal from this measurement is used to identify an entry in a lookup table. The entry is a control signal used to vary the input to the system so as to reach a desired output. The lookup table entries are configured so that as the output reaches the desired set point, smaller and smaller incremental steps are taken in varying the input.

Patent CA-2208482-A1 (CA)
Title: Transverse flux machine
Inventor: HILL WOLFGANG
IPC: H02K1/02
Filed: 1995-12-16
Abstract: In known transverse flux machines, the losses in the soft magnetic body prevent an increase in efficiency.  While the production of the winding is remarkable owing to its simplicity, the production of the laminated iron body conveying the magnetic flux incurs high costs.  In addition to the saturation in the iron, the use of air gaps restricts any increase in power density.  In accordance with the invention, the two air gaps (21) are arranged radially externally of the winding (15) and the magnetically hard and/or soft magnetic rotor parts (19, 20) which periodically close the magnetic circuit are arranged axially within the ends of the soft magnetic stator body (18).  This air gap arrangement gives rise to an air gap surface which is large relative to the external dimensions and the mass of the machine, and also relieves the load on the housing.  Owing to the segmentation of this u-shaped stator body, material waste during production is minimized and grain-oriented metal sheets can be used which, owing to their favorable properties, enable the efficiency and power density to be increased.  Segments of identical construction can be used in machines having different dimensions and power data. The type of construction according to the invention simultaneously reduces costs, weight, and losses in transverse flux machines.

Title: Compact laser apparatus and method
Inventor: DAVIS STEPHEN E
IPC: H01S3/113
Filed: 1996-03-29
Abstract: A laser system includes an apparatus and method having a primary laser resonator having a laser medium therein for producing a laser beam of a first wavelength and a second laser resonator optically connected to the primary resonator to allow a portion of the laser energy from the primary laser resonator to pass into the secondary laser resonator. An optical parametric oscillator is located intracavity of the secondary laser resonator and includes a non-linear crystal for producing a laser beam of a second wavelength therefrom. The dual resonators combine a secondary laser cavity and an optical parametric oscillator to produce a predetermined output wavelength. The compact multiple resonator laser system has a substrate mirror system having four mirror surfaces thereon positioned to form two laser resonators. A multi-pass corner cube is mounted to fold the light beams between a pair of substrate mirrored surfaces while a transfer corner cube is positioned to transfer a laser beam from one resonator to the second resonator to form a very compact pair of laser resonators. A method of producing a coherent light beam of a predetermined output wavelength uses the compact laser system apparatus.
