Title: Commande de gain pour mecanisme d'entrainement ventilatoire et procede associe
Inventor: SINDERBY CHRISTER
IPC: A61N1/05
Filed: 2000-07-27
Abstract: On utilise une commande de gain et un procédé de contrôle de la valeur d'un gain en conjonction avec un réseau d'électrodes pour détecter un signal représentant la sortie de la pulsion respiratoire d'un patient pendant l'inspiration et un ventilateur prévu pour assister l'inspiration du patient. La commande de gain comprend une entrée qui reçoit le signal représentant la sortie de la pulsion respiratoire ; un comparateur qui détermine si le signal représentant la sortie de la pulsion respiratoire est supérieur ou inférieur à un signal d'entraînement cible; et une unité d'ajustement du gain qui augmente la valeur d'un gain lorsque l'amplitude d'un signal représentant la sortie de la pulsion respiratoire est supérieure à l'amplitude d'un signal d'entraînement cible et qui diminue la valeur de ce gain lorsque l'amplitude du signal représentant la sortie de la pulsion respiratoire est inférieure à l'amplitude du signal d'entraînement cible. Le gain est appliqué au signal représentant la sortie de la pulsion respiratoire pour produire un signal représentant la sortie de la pulsion respiratoire amplifié utilisé pour commander le ventilateur pulmonaire. L'avantage de la ventilation à entraînement cible réside dans le fait que ce mode de ventilation ne dépend pas de la pression, ni des mesures de flux et de volume. Une ligne de ventilation qui fuit a pour effet de modifier l'entraînement respiratoire, ce qui provoque une modification de l'aide ventilatoire qui permet de renvoyer l'entraînement respiratoire à son niveau cible. De même, des changements de l'état métabolique ou patho-physiologique du patient qui provoquent à un entraînement respiratoire altéré seront compensés.

Title: Fluid actuated brake system
Inventor: GRAHAM JOHN M
IPC: B60T13/36
Filed: 1989-12-20
Abstract: IMPROVED FLUID ACTUATED BRAKE SYSTEM   ABSTRACT OF THE DISCLOSURE         An improved fluid actuated vehicle brake system (175), used when pressurized fluid is provided to one or more brakes (54, 56), provides a simple means for preventing a loss of pressure at one brake from affecting the other brake even though both may be fed through the same source line (38) by the same pressure source (4).  A separate vertically positioned closing valve (188, 206) is used between the brakes and the source line.  The closing valve relies on gravity only to bias its sealing element (116) from an upper sealing surface (124) to a lower, normal operating position (184).  The closing valve normally permits free flow of fluid through it.  However, if the fluid flow rate through the closing valve rises substantially above a normal flow rate, which could occur as a result of a rupture of the brake line (46) or a failure of the air or hydraulic brake itself, the sealing element is raised within the valve by the force of the fluid rushing through the valve and engages the upper sealing surface to seal the brake line.

The intravenous administration set includes a container of an IV fluid, a drip chamber, a drug formulation chamber, and an adapter-needle assembly.  The drug formulation chamber has a fluid inlet and a fluid outlet for maintaining a flow of IV fluid through the chamber.  A portion of the chamber wall is comprised of a material which is permeable to the drug but which prevents convective loss of the IV fluid.  A transdermal-type drug delivery device is adhered to the semipermeable/microporous wall portion.  Drug is delivered by the delivery device through the wall portion and into the flowing IV fluid.  The device delivers drug into the IV fluid at a rate that is independent of the flow rate of IV fluid through the formulation chamber.  The rate of drug delivery from the device into the IV fluid is controlled by either the wall portion or a membrane layer in the drug delivery device.  A plurality of drug delivery devices may be adhered to the wall portion to deliver a plurality of drugs or to deliver a single drug at a higher dosage rate.     A1/PATENTS.LGL/1486CIP1

Abstract: ABSTRACT          A process for preparing a fiber-reinforced, glass matrix composite and a composite as made by the process. The process employs forming a dilute aqueous slurry of solids comprising glass fibers, reinforcing fibers and binder material which may be partially or completely fibrous.  The dilute aqueous slurry is destabilized and the solids are collected on a porous support means.  They are then dewatered and dried to form a composite mat which can be hot-pressed into an article of manufacture.  The hot-pressed article of manufacture may then be heated, in the absence of pressure, to a temperature above the softening point of the glass, but below the degradation temperature of the reinforcing fibers, to provide a lofted composite.   34,034C-FF

Abstract: A diagnostic assay module for analytical procedures in which an optical signal developed by interaction between a component in a sample fluid, such as an analyte in a biological fluid, and one or more reagents in a resilient assay element is read by optical means.  The module includes a first member having one open side and a second member adapted to close the open side of the first member against a resilient assay element.  The area of the assay element to which the sample fluid is applied and wherein the optical signal developed by the interaction of the sample component and the reagent(s) in the assay element is read is maintained in a substantially horizontal orientation by flexure developed between complementing ramp surfaces on the respective first and second members. In a preferred embodiment the first member defines a liquid transport surface which, together with the assay element forms a fluid flow zone to provide for the uniform spreading of a sample fluid, introduced through an aperture in the member, across the surface of the assay element.  The volume of fluid in the fluid flow zone is controlled by the precise positioning of the assay element according to the invention.

Title: Projection tv deflection loss protection circuit
Inventor: NORMAN MARVIN N
IPC: G01R13/26
Filed: 1991-04-25
Abstract: ABSTRACT A voltage at a control grid of a cathode ray tube is generated at a blanking level to provide beam current blanking when horizontal deflection loss occurs. The control grid voltage at the blanking level is developed in a capacitor prior to an instant in which the horizontal deflection loss occurs. When the capacitor voltage is applied to the control grid to provide the blanking level, the capacitor is discharged slowly. To maintain the capacitor charged, prior to such instant when horizontal deflection is lost, the capacitor voltage is not applied to the control grid as long as the horizontal deflection is normal, regardless of whether vertical deflection loss occurs. Either horizontal deflection loss or vertical deflection loss will disable a video driver stage that controls the cathode of the cathode ray tube for providing additional beam current blanking capability.
