Abstract: A method of adjusting an audio signal equalizer setting. A first and a second equalizer setting are selected from a population of equalizer settings for undergoing a binary comparing decision. The two equalizer settings are presented to a user by consecutively replaying an audio signal filtered by an equalizing unit according to the first or to the second equalizer setting respectively. The user's binary comparing decision between the first and the second equalizer setting according to his preferences is acquired. Further binary comparing decisions are performed until all members of the settings population have been part of a binary comparing decision. A score for the each presented equalizer settings is adapted based on the user's binary comparing decisions results. A weighted averaging is performed, based on the scores, in the frequency domain between the equalizer settings that received a high score, to obtain the result of the equalizer adjustment method.

Abstract: A microphone unit is provided which includes a microphone for picking up sound of a unit which sound is to be picked up, a clamping unit having a first end configured to clamp to the unit and a second end for holding the microphone, a contactless vibration sensor configured to detect vibrations of the unit, and an audio gate unit coupled to the output of the microphone and to the output of the contactless vibration sensor as a trigger signal to allow the output of the microphone to be forwarded to an output terminal.

Abstract: A micro-reactor (10) is formed from a first glass block (11) having first and second grooves (14,17) formed in an upper surface (13) and a second glass block (12) having a lower surface (26) that closes the first groove (14) and parts of the second groove (17) to form corresponding channels. An aperture (31) extends through the second block (12) to a part of the upper surface (13) of the first block (11). This part (called the inner surface 32) has a number of parts (called the inner surface grooves) of the second groove (17) formed in it. The inner surface grooves can be closed by an end surface of a cylindrical insert (37) to form corresponding channel parts. A first chemical species can be bound to the end surface of the cylindrical insert (37) so that the first chemical species lies within the channel parts corresponding to the inner surface grooves. A second chemical species can now be passed through the channels of the micro-reactor for binding between the first and second chemical species.
