  • Patent number: 11973337
    Abstract: This invention relates to the technical field of harmonic elimination for ferromagnetic resonance for a voltage transformer (abbreviated as PT), in particular, to a harmonic elimination method for ferromagnetic resonance for an active resistance-matching voltage transformer based on PID-adjustment, including compiling a resistance matching algorithm; designing and building a harmonic elimination control system based on the PID control strategy; presetting an active resistance-matching strategy; designing an engineering scheme for placing resistors.
    Type: Grant

  • Patent number: 6725048
    Abstract: Methods, systems, and arrangements facilitate information interexchange between a telecommunications network and an information service provider. For example, a business-to-business (B2B) engine includes one or more logic modules for interfacing with the telecommunications network and with the information service provider. The B2B engine facilitates the reporting of, e.g., realtime information from the telecommunications network to the information service provider. This realtime information may include subscriber unit location that is proactively sent by the subscriber unit to the B2B engine for forwarding to the information service provider. To avoid possibly congesting the telecommunications network, the B2B engine is empowered to monitor the number of proactively-transmitted location messages and to limit them if they exceed a defined threshold.

  • Publication number: 20020037722
    Abstract: Methods, systems, and arrangements facilitate information interexchange between a telecommunications network and an information service provider (InfSP). For example, a business-to-business (B2B) engine includes one or more logic modules for interfacing with the telecommunications network and with the InfSP. The B2B engine facilitates the reporting of, e.g., realtime information from the telecommunications network to the InfSP. This realtime information may include subscriber unit location and may be acquired and/or reported based on a mapping data structure in, e.g., the B2B engine. The data structure maps a service class to one or more parameters that dictate or provide guidance with respect to which parameters are relevant, as well as their respective values, and a mechanism for achieving the stipulated parameters. The mechanism may include specific network nodes/entities as well as frequency of acquisition to thereby enable location-tailored content data and/or services to be provided to a subscriber.
