  • Publication number: 20240130392
    Abstract: A soluble cascara powder product with improved compositional and sensory characteristics, for use in food and beverage products is provided, as well as methods of preparing the soluble cascara powder. The soluble cascara powder may be a blend of powders derived from coffee cherry fruit to create a highly palatable and novel soluble cascara powder product, and one with desirable compositional characteristics such as phenolic content and bioactive compound content. Example methods of processing of the coffee fruit to prepare the soluble cascara powder may also result in soluble cascara powder that will result in advantageously low turbidity levels when used in beverage compositions.

  • Patent number: 11826925
    Abstract: In one aspect, inks for use with a three-dimensional printing system are described herein. In some embodiments, an ink described herein comprises a thiol monomer component and an ene monomer component. Moreover, in some cases, an ink described herein further comprises an additional (meth)acrylate monomer component differing from the ene monomer component. In some such cases, the additional (meth)acrylate monomer component can be polymerized separately from the thiol and ene monomers of the ink.

  • Publication number: 20210403733
    Abstract: In one aspect, inks for use with a three-dimensional (3D) printing system are described herein. In some embodiments, an ink described herein comprise 10-70 wt. % or 20-40 wt. % of a cyclopolymerizable monomer, based on the total weight of the ink. The cyclopolymerizable monomer comprises an acrylate moiety and an ethenyl or ethynyl moiety, and the ?-carbon of the acrylate moiety and the ?-carbon of the ethenyl or ethynyl moiety may have a 1,5-, 1,6-, 1,7-, or 1,8-relationship. Additionally, an ink described herein can have a viscosity of 1600 centipoise (cP) or less at 30° C., or of 500 cP or less at 30° C. and can be used to print a desired 3D article having mechanical properties similar to those of articles formed from thermoplastic materials.

  • Patent number: 9544404
    Abstract: Systems and methods are disclosed for optimizing Robust Header Compression (RoHC) to protect against context desynchronization resulting from a burst of lost packets. In one embodiment, a method of operation of a radio node to adapt a RoHC compressor of a radio node based on a transmit channel quality metric is provided. In another embodiment, systems and methods relating to improved RoHC SN decoding are disclosed. In one embodiment, a method of operation of a radio node includes determining a size of a Packet Data Convergence Protocol (PDCP) Sequence Number (SN) gap for a radio link between the radio node and a second radio node, and performing RoHC SN decoding based on the size of the PDCP SN gap.
