Abstract: A pump arrangement includes an axial-flow machine and a drive to convey fluid mounted in a housing. The axial-flow machine is formed by at least one first rotor having permanent magnets, a shaft connected to the first rotor and a stator arrangement with stator teeth distributed concentrically around the shaft axis circumferentially and axially separated from the first rotor by an air gap. The stator teeth have axially-opposite end portions and a tooth core therebetween wound with at least one coil winding. The second end portion, turned away from the first rotor, of each stator tooth forms a tooth root joined to a back plate. The first rotor is an eccentric disk and on the side away from the stator arrangement has an eccentric cam, radially spaced from the shaft axis, and rotatably and torque-transmittingly connected to the drive. An axial-flow machine and a compressor includes the pump arrangement.

Abstract: Aspects of the subject disclosure may include, for example, receiving, by a receiver through a medium from a transmitter, signals over an acoustic channel, where the receiving over the acoustic channel utilizes a high center frequency and provides for a high data rate, and where the medium is a fluid or a semi-solid medium. The device can receive power from the transmitter over the acoustic channel. Other embodiments are disclosed.

Abstract: A stator arrangement for an axial-flow machine includes a stator having stator teeth circumferentially distributed concentrically and axially separated from a rotor by an air gap. The stator teeth have two axially-opposite end portions and a tooth core therebetween. Each tooth core is wound with at least one coil winding. The first end portion facing the rotor forms a tooth tip having a tip cross-sectional area larger than the core cross-sectional area. The second end portion, turned away from the rotor, forms a tooth root, having a root cross-sectional area, which is joined to a reflux plate. The tooth tip of each stator tooth as well as the reflux plate respectively has at least one recess for at least one tooth securing device, and each stator tooth is securely joined by the at least one tooth securing device to the reflex plate in at least axial direction.

Abstract: The invention relates to a dry construction system for making partition walls (1), suspended ceilings or the like, with a support structure (2), a cladding (3) arranged on at least one side of this, and an insulation layer (4), wherein the support structure (2) comprises a plurality of carrier profiles (22), to which at least one cladding (3) is secured, and wherein the carrier profiles (22) are formed from a sheet material and exhibit in cross-section a basic section and two limb sections arranged perpendicular thereto, and comprise an embossing with regularly distributed elevations and depressions. In this situation, the centre-to-centre distance between two adjacent elevations of the embossing on one side of the sheet material is less than six times the rated sheet thickness, and the base section is connected to the adjacent limb section in each case by a curved section with an outer radius which amounts to at least three times the rated sheet thickness.

Abstract: A system and method includes a receiver configured to receive a communication signal from a transmitter. A motion determining unit connected with the receiver is configured to provide information about a motion of the receiver relative to the transmitter. An adaptive equalizer is connected with the receiver, the adaptive equalizer is configured to use the information about the motion to undo effects of time variation in the communication signal.
