20150238081 | WIRELESS COMMUNICATION OF PHYSIOLOGICAL VARIABLES USING SPREAD SPECTRUM - The present invention relates to a system and a method of measuring a physiological variable in a body. A basic idea of the present invention is to measure a physiological variable in a body by means of employing a sensor which is arranged to be disposed in the body for measuring the physiological variable. The sensor must be provided with a supply voltage in order to be operable. Therefore, a control unit disposed outside the body provides this supply voltage to the sensor. The control unit also receives, from the sensor, via a wired connection, signals that represent the physiological variables that are measured. The control unit is arranged with a communication interface and a modulator for wireless spread spectrum communication of the measured physiological variables for presentation purposes. | 08-27-2015 |

20100111685 | GAS TURBINE ENGINE COMPONENT, A TURBOJET ENGINE PROVIDED THEREWITH, AND AN AIRCRAFT PROVIDED THEREWITH - A gas turbine engine component is provided including at least one ring element, and a plurality of circumferentially spaced load carrying vanes extending in a radial direction of the ring element. The load carrying vanes have an internal structure with an anisotropic load carrying property, and the internal structure is configured so that a main load carrying direction is in parallel with the extension direction of the load carrying vane. The component includes a stiffening structure bridging the distance between at least two adjacent load carrying vanes in the circumferential direction of the ring element, and the at least two adjacent load carrying vanes are attached to the stiffening structure. | 05-06-2010 |
20110299917 | COMPONENT AND A GAS TURBINE ENGINE COMPRISING THE COMPONENT - A component includes a first member, a second member and a device for fastening the first member to the second member. A first hole extends through a portion of the first member and a second hole extends through a portion of the second member. The first member and the second member are positioned such that the first hole and the second hole coincide. The fastening device includes an elongated fastening element arranged in the coinciding holes and a bushing arrangement arranged around the fastening element and adapted to establish a load transmission path between the first member and the second member. A first part of the bushing arrangement is arranged such that an inner surface thereof is positioned at a distance from an exterior surface of the fastening element for establishing a first load transmission path via the bushing arrangement and bypassing the fastening element in a first load condition. Further, the fastening device is adapted to allow the first member to move relative to the fastening element in a second load condition such that the first part of the bushing arrangement can be brought into contact with the fastening element for establishing a second load transmission path between the first member and the second member via the fastening element. | 12-08-2011 |
20120213633 | GAS TURBINE ENGINE COMPONENT - A gas turbine engine component includes a ring element and a plurality of circumferentially spaced load carrying vanes extending in a radial direction of the ring element.
