  • Publication number: 20230399597
    Abstract: The 3D printing method disclosed here for the production of vascularized tissues and organs requires a droplet printer to produce photorealistic high-resolution prints and a device for applying non-directional or directional electromagnetic waves. The process uses a new type of capillary ink that crosslinks or undergoes a layer-forming reaction only in the edge area of the ink drops. Unbound capillary ink components are removed. The resulting cavities form a capillary network with diameters of up to approx. 10 ?m. Also disclosed is a novel printer table for supplying the printed tissue with medium during printing and a printer head supply unit for individually mixing the bio-inks from cell concentrate and various ink concentrates.

  • Patent number: 11799704
    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.
