Abstract: A hearing system is disclosed comprising a support unit, and at least one abutment unit, wherein the support unit supports the at least one abutment unit. The at least one abutment unit has a contact surface. The support unit is configured to be placed at a user's head such that the contact surface of the at least one abutment unit contacts the user's head in an area surrounding one of the user's ears, in particular, in an area of one of the user's mastoid bones. The at least one abutment unit comprises a contact element, the contact element being configured to transmit vibrations generated by a vibration generating unit towards the contact surface. The contact element is made of a fiber-reinforced plastic material.

Abstract: Method and device for measuring the content of a fluid flow, the fluid containing a combination of at least two of gas, oil and/or water. The method comprising the steps of:—repeatedly measuring the electrical properties of a cross section of the fluid and detecting time sequences identified by low gas content, especially characterized in that a gas bubble is not present,—in said periods of low gas content measuring the density of the fluid in the flow, wherein the density measurements are performed in at least one period of low gas content and the a fluid density is calculated based on the measured densities over said period or periods.

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.
