  • Oscillator circuit with RF suppression
    Patent number: 9869698
    Abstract: An oscillator circuit includes a phase-locked loop, a crystal resonator, first and second capacitors, and first and second impedance elements. The phase-locked loop is coupled between a first node and a second node. The crystal resonator is also coupled between the first node and the second node. The first capacitor is coupled between the first node and ground, and the second capacitor is coupled between the second node and ground. The first impedance element is coupled in a first circuit path from the first node to ground through the first capacitor. The second impedance element is coupled in a second circuit path from the second node to ground through the second capacitor.
    Type: Grant

  • Excessive surge protection method and apparatus
    Patent number: 7616420
    Abstract: A surge protection apparatus connected between an electrical power line source and a load includes a voltage input, an inductor, and a protective barrier. The voltage input is coupled to the electrical power line. The inductor is coupled between the voltage input and the load. The protective barrier is interposed between the inductor and the load, and is configured to physically isolate the inductor from the load.

  • Excessive surge protection method and apparatus
    Patent number: 7561399
    Abstract: An electrical meter includes a voltage input, a current input, a measurement device and a surge protection apparatus. The measurement device generates electrical power consumption measurements based upon the voltage input and the current input. The surge protection apparatus may include an inductor, a resistor and a positive temperature coefficient device (PPTC). A protective barrier is provided to physically isolate the surge protection apparatus from other components of the meter.
