A device for determining properties of a medium, comprising a carrier which can be brought in contact with the medium; at least one transmitter arranged on the carrier for exciting acoustic waves in the carrier; at least one receiver arranged on the carrier for receiving acoustic waves which originate from waves excited in the carrier by means of the transmitter; and first and second material regions arranged on the carrier, wherein the second material region absorbs sound waves with the frequency of the acoustic waves excited in the carrier more strongly than the first material region. The carrier has a first surface with which it is to be brought in con-tact with the medium and a second surface which faces away from the first surface, wherein the transmitter as well as the first and the second material region are arranged on the second surface.

Device and method for determining properties of a medium

An apparatus determines the properties of a medium in the form of a fluid or soft material. An acoustic waveguide has two opposing guide elements delimiting an interior space to be filled with a medium. The guide elements, upon filling the interior space with a medium, form an interface with the medium with an inner surface. A transmitter generates acoustic surface waves in the waveguide, which are received by a receiver. The waveguide can be coupled with an evaluation unit for determining physical properties of the medium based on a signal generated by the receiver. A housing accommodates the guide elements, transmitter and receiver. On the respective inner surface, at least a part of the acoustic surface waves can be converted into volumetric sound waves of the medium and at least a part of the volumetric sound waves can be converted into acoustic surface waves of the waveguide.

Apparatus for determining the properties of a medium in the form of a fluid or a soft material

An apparatus for determining a distance includes a converter element that generates n acoustic surface wave, a surface that feeds over at least part of the acoustic surface wave to a surface having a reflection point, and a processor that determines a distance between the apparatus and the reflection point from the propagation time of the acoustic surface wave. The converter element registers the acoustic surface wave reflected at the reflection point.

Apparatus and method for position determination

A bearing including a first and a second bearing element that are movable relative to one another, a lubricant arranged between the first and the second bearing element for reducing the friction between the first and the second bearing element, at least one transmitter for exciting acoustic waves in the first or the second bearing element, the transmitter being arranged on the first or the second bearing element; at least one receiver for receiving acoustic waves evoked by the transmitter, the receiver being arranged on the first or the second bearing element, wherein information related to properties of the lubricant can be determined using a signal generated by the receiver upon receipt of acoustic waves evoked by the transmitter. The invention is also related to a method for determining properties of a lubricant in a bearing.
