Abstract: A device (10) for determining a parameter of a fluid flow includes an elastically deformable boom (23, 28, 33, 42, 47), with an inflow area (29, 31, 32, 37, 38, 39, 40, 44, 45, 46, 49, 50) for fluid and a measurement apparatus (16) measuring deformation of the boom. A section of the inflow area is aligned askew and/or curved to a main fluid inflow direction (25). The boom has an inflow structure (24, 30, 34, 43, 48) on one free end. The inflow structure has the fluid inflow area. To determine the parameter of the fluid flow at high resolution, in particular a high angle resolution, the boom has a reflection surface (27) on a side facing away from the inflow structure and the measurement apparatus (16) has a laser (17). A beam axis (26) of the laser (17) is directed to the reflection surface (27) of the boom.

Abstract: A method for operating an electro-acoustic system (11) arranges an electro-acoustic device (10), for occluding an ear canal on an ear and uses a signal processing device (16) for processing a signal incoming at the device (10). A correction unit (17) of the signal processing device (16) modifies the signal incoming at the device (10). To reduce, to avoid or to compensate for an interfering or undesired change in a perception of ambient noises during the use of an electro-acoustic device occluding the ear canal, with the correction unit (17), a signal outgoing from the device (10) is generated in order to achieve acoustic transparency, in which, on the basis of the outgoing signal, a received signal is generated at the eardrum which is adapted so as to correspond to a free-ear received signal at the eardrum in the case of a free ear canal without the device (10).

Abstract: According to an embodiment, a method for producing stimulation pulses in a bilateral cochlear implant (CI) is disclosed. The method includes receiving a sound at a first microphone or a first microphone array positioned at or in the vicinity of a first ear of a user of the bilateral CI and receiving the sound at a second microphone or a second microphone array positioned at or in the vicinity of a second ear of the user of the bilateral CI. Furthermore, generating, using the first microphone or first microphone array, a first microphone signal in response to the sound received at the first microphone or first microphone array and generating, using the second microphone or second microphone array, a second microphone signal in response to the sound received at the second microphone or second microphone array.

Abstract: A process is described for the production of one or more of linear nitriles, amides and formamides which includes reacting a nitrogen containing compound, such as ammonia or NOx, and a synthesis gas over a catalyst at a temperature of between 160° C. and 400° C. and a pressure of between 1 bar and 50 bar. A further process for the production of one or more of linear phosphorous containing compounds is also described, which includes reacting a phosphorous containing compound, such as a phosphine, and a synthesis gas over a catalyst at a temperature of between 160° C. and 400° C. and a pressure of between 1 bar and 50 bar. A supported cobalt, iron, ruthenium or rhodium catalyst or an unsupported (bulk) promoted iron catalyst, modified with a promoter is used. The synthesis gas is a mixture of hydrogen and carbon monoxide, in a ratio from 0.5:1 to 5:1; or a mixture of hydrogen and carbon dioxide; or a mixture of water and carbon monoxide.
