  • Wet electrolytic capacitor containing a cathode coating
    Publication number: 20070211413
    Abstract: A wet electrolytic capacitor that includes an anode, cathode, and an electrolyte is provided. The cathode contains a substrate and a coating overlying the substrate. The coating comprises a sintered body containing carbonaceous particles (e.g., activated carbon) and inorganic particles (e.g., NbO2).

  • Temperature stabilized constant current source suitable for charging a highly discharged battery
    Patent number: 6225787
    Abstract: A temperature stabilized, constant current source of the present invention includes a feedback control stage that provides a substantially constant battery charging current at a particular temperature. A temperature stabilized current source stage includes a negative temperature coefficient current source that provides a countervailing control current to a positive temperature coefficient current source that is coupled from a sensing resistor. The temperature dependencies of the positive and negative temperature coefficient current sources tend to cancel each other out so as to provide a temperature stabilized current to the sensing resistor. In this way, a control voltage is developed across the control resistor that is independent of resistor temperature dependencies.
