  • Patent number: 11953576
    Abstract: A smart current transformer for determining primary current or power consumption, by stepping down the primary current to a secondary current for subsequent measurement by a connected meter. The current transformer is provided with a connected non-volatile memory for storing calibration data (and optionally identification data) regarding that particular current transformer. The calibration data can include the gain error and/or phase delay for the current transformer, as determined from prior calibration testing of the current transformer. The calibration data may be communicated to or otherwise determined by the meter, and used to calibrate the measurement of the secondary current, in order to determine the primary current or power consumption. Also disclosed is a system and method utilizing such a smart current transformer.

  • Publication number: 20230253782
    Abstract: A modular load management system comprises one or more compact modules designed to fit in the wiring troughs of a standard AC distribution panel of a building. The modules include one or more input terminals to receive electrical power from one or more circuit breakers in the panel and deliver power to load circuits of the building via one or more output terminals. The modules contain at least one disconnect switch for disconnecting circuits from breakers in response to a remote or locally-generated control signal. The modules may also include current sensors on some or all terminals, such that power and energy flow may be monitored on a per-circuit basis.

  • Publication number: 20230199385
    Abstract: An electronic apparatus that includes a first port configured to receive an incoming audio signal, a second port, and a controller configured to be coupled to the first port and the second port. The electronic apparatus further includes a switch configured to selectively decouple the controller from the second port when the first port receives the incoming audio signal. Decoupling the controller prevents an electrostatic discharge occurring on the second port from reaching the controller when the controller is receiving the incoming audio signal from the first port.

  • Publication number: 20220255862
    Abstract: This application provides a packet forwarding method, a device, a storage medium, and a system. A match condition and a path parameter are carried in a control message, and the path parameter includes an address identifier and a path feature identifier, so that when there are a plurality of forwarding paths between two devices in a network and when a first device receives a packet that meets the match condition in the control message, the packet may be forwarded on a forwarding path corresponding to the path parameter. The method provided in this application helps reduce network configuration complexity.

  • Patent number: 11407987
    Abstract: The present invention relates to a mannanase PMan5A mutant having improved heat resistance, a gene encoding the mutant and application thereof. The mutant is obtained by a substitution of histidine with tyrosine at amino acid residue 93, phenylalanine with tyrosine at amino acid residue 94, leucine with histidine at amino acid residue 356, and/or alanine with proline at amino acid residue 389. The thermal tolerance of the single site mutation mutant H93Y, L356H and A389P are greatly improved over that of the wild-type mannanase PMan5A, and the thermal tolerance of the combination mutants shows the stack effect of the single site mutation, demonstrating the amino acids at the sites of 93, 94, 356, and 389 play an important role for the thermal stability of the mannanase of GH5 family.

  • Publication number: 20210388411
    Abstract: The present invention relates to the field of genetic engineering, particularly to a recombinant expression vector for rapidly screening the high expression strains and a method for rapidly screening high expression strains. In the invention, an exogenous red fluorescent protein and Aspergillus fumigatus cell surface protein localization signal are fused and expressed, and the fusion gene (DsRed-AfMP1) is integrated into the genome of Trichoderma reesei, so as to construct a strain displaying red fluorescent protein on the surface of Trichoderma reesei. By sorting Trichoderma reesei strains with red fluorescent protein on the surface by flow cytometry, genes beneficial to the improvement of cellulase activity can be quickly isolated.
