  • Patent number: 11032739
    Abstract: A header compression indicator may be used to enable header compression between a device and a gateway and between end devices in a network of constrained devices. The header compression indicator may be used to signal that header compression is in use, along with which context is to be used, and parameters thereof. The header compression indicator may also be used to trigger creation, update, retrieval, or deletion of a header compression context dynamically. A header context data format may be used to convey the encoding of header option information and corresponding data used in the management of the header compression contexts. Header compression contexts may be created, modified, queried, or deleted dynamically via existing messaging frameworks and operations, e.g., by appending a header compression indicator to existing standard messages.

  • Patent number: 11019155
    Abstract: A batch of CRUD operations can be coupled with the resource discovery operation and directly conducted on the matched resources, without initiating new CRUD requests. New functionality at the Originator and Receiver can differentiate the resources for which criteria matching is applied from the resources included in the discovery/filtering results. Enhanced functionality at the Originator and Receiver can combine discovery with RESTful operations targeting a resource set different than but related the discovered resources. Other enhancements may be used to request discovery of resources in a specified relationship to those matching a filter, or to request group formation based on the result.

  • Publication number: 20210149454
    Abstract: The disclosure relates to a biaxial hinge mechanism including a positioning plate, a first main shaft, a second main shaft, a cam, and a linkage assembly. The positioning plate has a first through hole and a second through hole. The first main shaft is movably disposed through the first through hole. The second main shaft is rotatably disposed through the second through hole. The cam is fixed on the second main shaft. The linkage assembly is connected to the first main shaft and movable with the cam. When the second main shaft is rotated in a specific direction, the cam pushes the linkage assembly to force the first main shaft to move away from the second through hole so as to increase an axis distance between the first main shaft and the second main shaft. In addition, the disclosure relates to an electronic device having the biaxial hinge mechanism.

  • Publication number: 20210139553
    Abstract: The present disclosure provides a cytokine-based bioactivatable drug construct (“VitoKine”) platform that aims to reduce systemic mechanism-based toxicities and lead to broader therapeutic utility for proteins and cytokines such as IL-15 and IL-2 for the treatment of cancer, autoimmune diseases, inflammatory diseases, viral infection, transplantation and various other disorders. The novel VitoKine constructs of the present invention comprise: 1) a tissue or disease site targeting moiety D1 domain (“D1”), 2) a bioactivatable moiety D2 domain (“D2”), and a concealing moiety D3 domain (“D3”). Importantly, because the “active moiety” of the VitoKine construct will remain inert until activated locally by proteases that are upregulated in diseased tissues, this will limit binding of the active moiety to the receptors or to the targets in the peripheral or on the cell-surface of non-diseased cells and tissue to prevent over-activation of the pathway and reduce undesirable “on-target” “off tissue” toxicities.

  • Patent number: 11001825
    Abstract: The present disclosure discloses a thermophilic L-asparaginase mutant and screening and fermentation methods thereof, and belongs to the field of gene engineering, enzyme engineering and fermentation engineering. In Bacillus subtilis 168, a Pyrococcus yayanosii CH1-derived L-asparaginase encoding gene is used as a template, and a mutation library is constructed by an error-prone PCR (epPCR) technology. A mutant strain with improved specific enzyme activity is screened through a high-flux screening method of synchronous cell disruption and enzyme activity measurement. Mutated residues included in a positive mutant are analyzed to construct a composite mutant strain S17G/A90S/R156S/K272A with improved specific enzyme activity and specific enzyme activity of 3108 U/mg. An expression quantity of the composite mutant strain in the Bacillus subtilis 168 is increased through measures of a strong promoter P43 and RBS optimization.
