  • Patent number: 8877211
    Abstract: A BHV-1 mutant virus has been made that incorporates into a single virus two or more deletions in one or more of three genes—glycoprotein N, glycoprotein E and Us9. Specifically, a BHV-1 UL49.5?30-32 CT-null virus was made and tested. This mutant virus was then used to incorporate additional changes, e.g., the glycoprotein E cytoplasmic-tail deletion, the Us9 deletion, or both. This triple mutant BHV-1 UL49.5?30-32 CT-null/gE CT?/Us9? virus will be superior to the current BHV-1 mutants because the mutant virus will not be shed following reactivation, will be a DIVA based on gE CT-specific serum antibodies, and will induce better protective response by inducing higher SN titers and better cellular immune response. This new virus will have sufficient viral replication in the nasal epithelium and will be a good vaccine for protection of cattle from BHV-1. The new mutant viruses can also be used as vectors for exogenous genes.

  • Patent number: 8773828
    Abstract: The present invention relates to a busbar differential protection method. For each bay, firstly, zero-crossing point of voltage is determined according to sample values of voltage, then the current values are re-sampled on a current fitting curve by using zero-crossing point of voltage as a synchronous signal according to a given sampling time period to get a sample sequence. The sample sequence is comprised of current values of sampling points and sample serial numbers. The sample serial numbers of sampling points at the same time are same for the sample sequence of respective interval. Finally, computing is done to sample sequences of respective intervals, and differential protection is achieved.

  • Patent number: 7660083
    Abstract: An electromechanical/solid-state AC relay has an electromechanical winding coil that moves an armature to force mechanical contacts to open or close. Electrical arcing across the mechanical contacts that occur as the contacts are opening or closing can damage and severely reduce the lifetime of the relay. Contact arcing is prevented by pulsing a triac on for a short period of time just before and after the mechanical contacts make or break contact. The triac limits the voltage difference across the mechanical contacts to less than one volt to prevent arcing. The triac is turned off after the mechanical contacts finish moving, reducing the heating and average power through the triac. A zero-sampling circuit that detects when the AC input voltage switches across 0 volts and activates a control integrated circuit to switch on the triac during zero-crossings to minimize power surges.
