  • Patent number: 11009166
    Abstract: The invention relates to a locking coupling including a first coupling unit and a second coupling unit, which in each case extend along a longitudinal axis and are designed to be identical. Each coupling unit includes a valve unit and a locking unit. The first and the second valve unit are designed to form a fluid connection between the first and the second coupling unit, and the first and the second locking unit are designed to connect the first coupling unit and the second coupling unit mechanically to one another. The first coupling unit includes an actuating element, by actuation of which the first and the second coupling unit can be mechanically connected to one another via the first and the second locking unit and can be fluidically connected to one another via the first and the second valve unit.

  • Patent number: 10992353
    Abstract: Communication systems and methods in accordance with various embodiments of the invention utilize modulation on zeros. Carrier frequency offsets (CFO) can result in an unknown rotation of all zeros of a received signal's z-transform. Therefore, a binary MOCZ scheme (BMOCZ) can be utilized in which the modulated binary data is encoded using a cycling register code (e.g. CPC or ACPC), enabling receivers to determine cyclic shifts in the BMOCZ symbol resulting from a CFO. Receivers in accordance with several embodiments of the invention include decoders capable of decoding information bits from received discrete-time baseband signals by: estimating a timing offset for the received signal; determining a plurality of zeros of a z-transform of the received symbol; identifying zeros from the plurality of zeros that encode received bits by correcting fractional rotations resulting from the CFO; and decoding information bits based upon the received bits using a cycling register code.

  • Publication number: 20210072013
    Abstract: The invention relates to a boundary layer probe for determining a fluid flow, comprising a measuring surface which is formed on a probe wall and with which a fluid flow to be determined is in contact during a measuring operation. The boundary layer probe also comprises an assembly of measuring obstacles that are formed in the region of the measuring surface as obstacles which disrupt the fluid flow in a flow region adjacent to the measuring surface, each of which has an elongated obstacle course extending over a particular obstacle length, and which are arranged at substantially equidistant angular distances in the circumferential direction. The boundary layer probe additionally has pressure measuring points, each of which is radially adjacent to an associated obstacle in order to detect a local pressure in the region of the measuring surface. The invention additionally relates to a measuring assembly and to a method for determining a fluid flow. (FIG.
