  • Patent number: 8636007
    Abstract: A patient interface system for delivery of a supply of air at positive pressure to the entrance of a patient's airways for treatment of sleep disordered breathing includes an air delivery tube connected to a flexible portion of a plenum; a vent structure having sufficient rigidity to support its own weight under gravity and/or not to block or fold under tube movement or tube drag; and a patient interface structure. The patient interface structure includes a seal forming structure arranged on a top portion of the plenum; and a seal positioning and stabilizing structure connected to a flexible portion of the plenum. The seal-forming structure is substantially decoupled from a tube drag force.

  • Patent number: 8573201
    Abstract: A headgear for use with a patient interface for delivering a flow of breathable gas to a patient includes at least a strap (741) adapted to position the patient interface in sealing engagement with the patient's airways. The strap is constructed from an elastomer and a first side of the strap includes a first region (215) on a portion of its surface that is textured to reduce friction with objects contacting the strap. A textured surface coating for a portion of an elastomer strap included in a headgear system is adapted to contact the skin of a patient, when in use, and the coating has a Ra value greater than zero. A vent (500) for use with a patient interface for delivering a flow of breathable gas to a patient includes a plurality of rises (580) and runs (570) in a stepped arrangement; and a plurality of holes (510) in the stepped arrangement for the venting of gas.

  • Publication number: 20110011762
    Abstract: Disclosed herein is a moving device in the form of a bag having an aperture allowing furniture to be placed therein, a closure for the aperture (such as a “hook and loop” fastener, buttons, a zipper, or other suitable device), and at least one tensioning strap to tighten the bag around the furniture. The bag can be made of a flexible and/or waterproof material, and can include additional padding. In some embodiments, the bag can be shaped as a prism, but can also take other shapes. The tensioning strap(s) can extend partially or entirely around the bag, and can be fastened using a hook and loop fastener, bucket or other suitable device. In some embodiments, at least one longitudinal tensioning strap and at least one lateral tensioning strap are provided. The bag can also include one or more handles, one or more transparent viewing windows, and a document pouch.

  • Publication number: 20100229868
    Abstract: A headgear for positioning a patient interface structure for delivering a pressurized flow of breathable gas to the airways of a patient includes at least one flexible strap loop which is attachable to the patient interface structure by a forked region of the at least one strap loop that is mountable on the patient interface structure. The at least one strap loop positions the patient interface structure on the face of the patient. The forked region includes two forks adapted to be attached to an upper and lower portion on the patient interface structure. The two forks are connected by a bridge so that the forked region is divided into a first region and a second region, and the first region is mountable on the patient interface structure.

  • Publication number: 20070183898
    Abstract: The present invention provides an airfoil a second stage nozzle guide vane having an external surface with first and second sides. The external surface extends spanwise between a hub and a tip and streamwise between a leading edge and a trailing edge of the airfoil. The external surface includes a contour substantially defined by Table 1 as listed in the specification.

  • Publication number: 20050206890
    Abstract: The present invention relates to a method and device for ascertaining characteristics relating to porosity and grain size in rock sample. Four illuminators A, B, C and D direct collimated illuminating beams to a point O at the centre of a sample 40 and have projections onto the plane of the surface of the sample 40 at points A1, B1, C1, and D1. Angles <AOA1, <BOB1, <COC1, and <DOD1 have the same value of 45°. A camera (41) located directly above the point (O) acquires four images as the illuminators are individually illuminated. A processing section receives the acquired image data on line (42) and, after filtering, a common point distribution is evaluated based on the common points in the light intensity distribution data of two pairs of images with opposite illumination directions is found (A & C, B & D). At the same time, an edge enhancing distribution is evaluated based on the opposing value points in the light intensity distribution data for the opposing directions.

  • Patent number: 5811947
    Abstract: A vehicle anti-lock braking (ABS) system having a motor-driven pump (10) for providing a hydraulic supply to the ABS system. The pump motor (10) is controlled by a series device in the form of an electronic switch (16), such as a MOSFET, to enable frequent testing of the motor circuit by short pulses which produce no significant noise. Feedback to control motor speed is obtained by measuring the e.m.f. generated by the motor (16) after it has been switched off and after a delay to allow the back e.m.f., caused by switching off the motor, to decay (preferably to zero) before the measurement operation begins. The generated voltage is integrated during a motor switch-off period, the motor speed being established in this period by subtracting the measured integrated voltage when acting as a generator from the main supply voltage (B+) .

  • Patent number: 5762245
    Abstract: An automobile accessory to be attached to the inside of the trunk lid. When the trunk lid is open, it provides a horizontal shelf in its operative position. The horizontal shelf provides space and support for various items, such as food and beverages. The device has two planar elements hingedly attached to each other along one edge, respectively. The two opposite edges of the planar elements are attached to each other by flexible adjustable straps. One planar element is fabricated with a uniform pattern of aperatures to cooperate with the trunk lid structure and provide different attachment points necessary for different automobiles. Fasteners, extending through the selected aperatures, are attached to the appropriate points on the inside of the trunk lid by bracket, magnet or otherwise adhered thereto, affixing the planar element to the trunk lid.
