  • Patent number: 11131712
    Abstract: A device for inspecting the rotor windings of a generator includes a sequential logic circuit that generates a full-cycle pulse. A high-voltage full-cycle pulse matching generator couples the full-cycle pulse generated by the sequential logic circuit to form a corresponding transient bidirectional rotating magnetic field pulse. The transient bidirectional rotating magnetic field pulse is transmitted to two ends and a large shaft of the generator rotor winding through an impedance-matched connecting line. The transient bidirectional rotating magnetic field pulse generates a resonance effect with each large coil in the rotor. The pulse signal coupling feedback acquisition circuit couples all waveforms reflected by the generator rotor to form a magnetic field waveform, and the magnetic field waveform is transmitted to a data acquisition system by an operational amplifier. A central processing unit transmits a digital information stream to an upper computer.

  • Patent number: 10558636
    Abstract: Disclosed herein are system, method, and computer program product embodiments for providing read queries latch-free access to an index page. In an embodiment, a processor receives a request from a read query to access one or more records of an index page. The index page includes an update pointer and a slot array. The processor locates one or more updates prepended to the index page by locating a most recently prepended update indicated by the update pointer. Then, the processor generates a local offset table with entries in the slot array and the located one or more updates. The generated local offset table enables the processor to provide the read query access to the one or more records of the index page.
