  • Patent number: 11943340
    Abstract: In some examples, for process-to-process communication, such as in function linking, a virtual channel can be provisioned to provide virtual machine to virtual machine communications. In response to a transmit request from a source virtual machine, the virtual channel can cause a data copy from a source buffer associated with the source virtual machine without decryption or encryption. The virtual channel provisions a key identifier for the copied data. The destination virtual machine can receive an indication data is available and can cause the data to be decrypted using a key accessed using the key identifier and source address of the copied data. In addition, the data can be encrypted using a second, different key for storage in a destination buffer associated with the destination virtual machine. In some examples, the key identifier and source address is managed by the virtual channel and is not visible to virtual machine or hypervisor.

  • Publication number: 20230322953
    Abstract: Disclosed is a binding protein having at least two protein functional regions, the binding protein comprising a protein functional region A and a protein functional region B; the protein functional region A and the protein functional region B target different antigens or epitopes, the protein functional region A is a Fab or a scFv structure, the protein functional region B is a VH structure, and there are one or more of each of the protein functional region A and the protein functional region B. A multi-specific binding protein has a smaller molecular weight, fewer polypeptide chains, and a simpler structure. By means of different structure types, relative positions, binding valence and other parameters, the functional activities for different targets can be adjusted, and then different combinations of activities can be designed so as to meet the needs of different dose combinations of clinical combinations.

  • Patent number: 9059767
    Abstract: Embodiments of the present invention disclose a microwave transmission method, apparatus, and system using CCDP and XPIC, and relate to the field of mobile communication technologies. The microwave transmission method includes: sending two channels of service that are corresponding to the same frequency and have different polarization directions, where the two channels of service are paired into one logical group; and when receiving, through a feedback channel, a failure signal sent by another end, closing sending of a channel of service that is indicated by the failure signal. In the embodiments of the present invention, after the failure signal sent by the another end is received, the sending of a channel of the service that is indicated by the failure signal is closed, so that no interference is caused to another channel of service, thus ensuring that another channel of service is received correctly.

  • Patent number: 8885785
    Abstract: Embodiments of the present invention disclose a CDR circuit and a terminal, where the CDR circuit is configured to perform clock synchronization in a terminal with EEE function, and the CDR circuit includes: a phase detector, a first phase signal selector, a loop filter, a numerical controlled oscillator, a second phase signal selector, a phase signal generator, and a state machine. In the embodiments of the present invention, after the terminal enters a REFRESH state from a QUIET state, the CDR circuit can implement clock synchronization with a peer end without waiting for the loop filter and the numerical controlled oscillator to be converged, but the phase signal generator generates a phase signal satisfying a preset clock synchronization condition, and the second phase signal selector selects the phase signal satisfying the preset clock synchronization condition as the phase selection signal of the CDR.
