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.

A method for measuring physical properties or characteristics of liquids uses an acoustic transfer system that utilizes Rayleigh waves. A wave guide with at least one test section formed from a solid surface made from non-piezo-electric material, contacts the liquid medium to be measured and/or a transfer system. A sender sends acoustic wave energy that includes at least one Rayleigh wave, and at least part of the acoustic wave energy leaving the sender passes at least once through a mode converter on its way to the receiver, whereby this part of its wave energy is converted at least partly from a Rayleigh wave (RW) into a volume sound wave (VW) or vice versa. The physical characteristics or physical properties of the liquid are then determined using changes of at least a parameter of the Rayleigh wave.
