HIGH TEMPERATURE PRESSURE SENSOR ELEMENT, PARTICULARLY FOR MEASURING PRESSURES INSIDE JET ENGINES, METHOD FOR THE PRODUCTION THEREOF AND COMPONENT FOR JET ENGINES
The invention relates to a high temperature pressure sensor element (10; 20), in particular for jet engines, comprising a substrate (11) with an inner region (12) configured therein, a defomable membrane (13) which separates the inner region (12) from the outer region and deforms during operation in the event of a change of pressure, and a strain gauge element (14a, 14b, 14c) disposed on the membrane (13) for measuring the deformation of said membrane (13). The substrate (11), the membrane (13) and the strain gauge element (14a, 14b, 14c) are all made of the same high temperature stable material, particularly an alloy, such as a nickel-based alloy. A component for a jet engine, such as for example a turbine blade for an aircraft or a rocket engine, comprises such an integrated high temperature pressure sensor element (10; 20).

GLOBAL INFORMATION AND HAZARD WARNING SYSTEM USING SATELLITE NAVIGATION SYSTEMS AND USER TERMINALS
The invention relates to a method and devices for a global information and early warning system, based on satellite navigation systems and user terminals, comprising the following steps and devices for carrying out said steps: transmission of at least one warning message about one or more danger zones via a satellite navigation system to user terminals in at least one information coverage region, reception of the at least one warning message by a user terminal in the at least one information coverage region and checking by the user terminal whether the user terminal is affected by the warning message.

HIGH-RESOLUTION SYNTHETIC APERTURE RADAR DEVICE AND ANTENNA FOR ONE SUCH RADAR DEVICE
The invention relates to a high-resolution synthetic aperture radar device (10) comprising: at least one emission antenna (TX1-TX3) for generating and emitting radar pulses for scanning an object (12), and a reception antenna (14) for receiving the emitted radar pulse beams (20, 22, 24) reflected off an object, the reception antenna (14) comprising a plurality of sub-apertures (RX1-RX17) which are arranged along the elevation and form a minimum number of azimuthal apertures. The high-resolution synthetic aperture radar device is embodied in such a way that pulse signals (18) are emitted at irregular time intervals.
Disclosed is a high-frequency measuring hall for measuring large test objects. Said measuring hall is composed of an air-supported membrane structure or textile structure which has a spherical or elliptic contour and is largely permeable to electromagnetic radiation and in which the floor is covered with absorber material in order to absorb the electromagnetic radiation reflected by the inner side of the surface. The structure and the material used, which is largely permeable to electromagnetic waves, make it possible to create a structure that is less expensive than conventional hall structures, allowing a substantial reduction of the amount of absorber material used.
The invention relates to an assembly for determining the position and orientation of a flying object (12, 14), in particular a flying object in space. Said assembly comprises a ground segment (16), which has at least one pseudolite station (18) that is located on the earth's surface and transmits a navigation signal (20), uniquely identifying said pseudolite station, into space and a user segment that comprises at least one sensor (46) that is situated in the flying object (12, 14). The sensor is configured to receive the navigation signal (20) of the pseudolite station or stations (18) and to determine its absolute position and orientation in space using the received navigation signal (20).
