Abstract: The invention relates to a bloom retarding fat composition comprising a component A and a component B; said component A being present in an amount of 40-95% (w/w) of said bloom retarding fat composition, and said component B being present in an amount of 5-60% (w/w) of said bloom retarding fat composition; wherein said component A comprising a fat composition having a content of SatOSat TAGs of 60% (w/w) or higher; and wherein said component B comprising a fat composition having a content of saturated fatty acids of 30% (w/w) or less, and a total content of Sat2U TAGs of 18% (w/w) or less, and a content Sat3 TAGs of 8% (w/w) or less; with the proviso that if the content of SatSatU TAGs in component B is 1% (w/w) or more, then the molar ratio of SatSatU: SatUSat TAGs is 1 or higher; and wherein Sat is a CI 6-20 saturated fatty acid, and wherein O stands for oleic acids; U stands for unsaturated fatty acids, including oleic acid.

Abstract: This invention relates to a system for measuring solid particles, e.g. sand, in a fluid flow in a pipe, comprising at least one acoustic sensor for registering acoustic signals generated from collisions between particles and a surface. The pipe comprises a constriction through which the fluid flow passes, and that at least one of said acoustic sensors are positioned in relation to said constriction, and on a surface facing toward the flow so as to receive acoustic signals resulting from collisions between particles and the surface.

Abstract: The present invention relates to a miniature electro-acoustic transducer comprising a magnetic circuit comprising a permanent magnet assembly adapted to generate a magnetic flux in an air gap, the magnetic circuit comprising a magnetically permeable yoke having one or more air flow passages arranged therein, the one or more air flow passages being in fluidic communication with the air gap to allow pressurised and/or heated air trapped below a diaphragm of the transducer to be guided to the exterior of the magnetic circuit via said one or more air flow passages. The transducer further comprises a voice coil positioned in the air gap. The voice coil is operatively connected to the diaphragm. The one or more air flow passages are arranged in the yoke so as to guide pressurised and/or heated air in a plane being substantially perpendicular to the direction of movement of the diaphragm.

Abstract: A suspension member for a diaphragm, the suspension member comprising an inner portion being adapted to be attached to a substantially stiff piston part, a outer portion arranged on or integrated with a substantially stiff support member so as to mechanically stabilise the suspension member, and a flexible member connecting the inner and outer portions. The present invention further relates to an electro-acoustic transducer, preferably a miniature electro-acoustic transducer, applying such suspension member.

Abstract: The present invention relates to a suspension member for a diaphragm and to an electro-acoustic transducer applying such suspension member. The suspension member comprises an inner portion being adapted to be attached to a piston, an outer portion being adapted to be coupled to a substantially stationary portion of an associated electro-acoustic transducer, and a flexible member connecting the inner and outer portions. The flexible member comprises at least one electrically conducting element adapted to transport electrical signals across the suspension member.

Abstract: A miniature multi-loudspeaker module comprising a housing including a magnetic circuit having magnetic means and a magnetically conducting body defining a magnetic field, and first and second coplanar diaphragm and coil assemblies, which are separately movable. The housing is attached to a front cover, which includes first and second sound outlet openings leading to the first and second diaphragms. Preferably, parts of the magnetic circuit can be shared by the two diaphragm and coil assemblies. Preferred embodiments have two diaphragm and coil assemblies that can be separately electrically terminated to enable stereo sound reproduction and can be operated out of phase to serve as a vibration source. Such modules may be utilized for providing stereo sound in, e.g. mobile phones. The front cover may also comprise a sound outlet opening. The receiver signal can be generated by the two diaphragms or by a separately movable third diaphragm and coil assembly.

Abstract: A method and apparatus for displaying an advertising or promotional image or message provides the projection of one or more light patterns, and still or motion pictures within the light patterns, onto a visible surface or screen. The outline of the surface or screen may be identical to the outline of the projected light pattern.
