  • Patent number: 9209438
    Abstract: A hermetically-sealed electrical feed-through device includes a conductor, an insulating sleeve, and an outer ferule interconnected in a manner preventing relative rotation therebetween and/or includes a thermocouple in direct contact with the conductor for monitoring temperature. The conductor can have a body section extending along an axis and having an outer contour including flats or an outwardly-extending eccentrically-shaped lobe. The sleeve confronts and covers the body section of the conductor and accommodates and engages the outer contour at the flats or lobe to prevent rotation of the conductor relative to the sleeve, and the outer ferrule sandwiches the insulating sleeve between the outer ferrule and the outer contour of the conductor. The outer ferrule accommodates and engages the sleeve adjacent the outer contour of the conductor at the flats or lobe to prevent rotation of the insulator sleeve relative to the outer ferrule.

  • Patent number: 9136718
    Abstract: In a charge and discharge control circuit, a mode control part manages a normal mode in which voltages at a power terminal and an overcurrent detection terminal are monitored, a time-shortening mode in which predetermined delay times for detecting an overcharge, an overdischarge, and an overcurrent are shortened, and a protection mode in which a signal to stop a charge current or a discharge current is output when an abnormality is detected in the normal mode. A transition is made from the normal mode to the time-shortening mode when the voltage at the power terminal exceeds a predetermined value, and a transition is made from the time-shortening mode to the protection mode when one of the overcharge, overdischarge, and overcurrent is detected.

  • Patent number: 9057631
    Abstract: A smoke detector with an easily-readable battery-life display is an apparatus that visually displays the remaining battery life for a smoke detector through an analog or digital device. The apparatus primarily includes a smoke detector, a battery power indicator, and a reference resistor. The battery power indicator is positioned on the underside of the smoke detector so that a person can look up at the smoke detector mounted on a ceiling and view the battery power indicator. The reference resistor draws a small amount of current from the battery, which allows the battery power indicator to measure the gradual reduction of voltage readings across the reference resistor and consequently determine the remaining battery life, and thus displaying the remaining battery life in the appropriate zone (red, yellow or green).

  • Publication number: 20150147614
    Abstract: In some variations, an apparatus provides real-time monitoring of voltage and differential voltage of both anode and cathode in a battery configured with at least one reference electrode. Voltage monitors are connected to a computer programmed for receiving anode voltage signals; receiving cathode voltage signals; calculating the derivative of the anode voltage with respect to time or with respect to capacity; and calculating the derivative of the cathode voltage with respect to time or with respect to capacity. Other variations provide an apparatus for real-time assessment of capacities of both anode and cathode in a battery, comprising a computer programmed for receiving electrode voltage signals; estimating first and second electrode open-circuit voltages at two different times, and correlating the first and second electrode open-circuit voltages to first and second electrode states of charge, respectively, for each of anode and cathode. The anode and cathode capacities may then be estimated independently.
