  • Patent number: 10983170
    Abstract: An apparatus for monitoring battery swelling includes a conductive layer adhered to a battery pack, a surface opposite the battery pack, a flex layer adhered to the bottom of the surface, and a resistance measurement circuit. The conductive layer includes one or more conductive strips. The flex layer includes a resistive pattern with one or more serially connected resistive segments. Each resistive segment is aligned to a respective conductive strip. The surface is positioned over the battery pack so that initially the resistive pattern is not in contact with and is electrically separated from the conductive layer. The resistance measurement circuit is connected to the resistive pattern to detect changes in resistance of the resistive pattern. When the battery pack swells, the resistive pattern comes in contact with the conductive layer, thereby shorting a resistive segment, and causes the resistance measurement circuit to detect the change in the resistance.

  • Patent number: 10976377
    Abstract: A device may include a wire interface (e.g., port), a detection circuit and a microcontroller. The detection circuit may include a resistor, a comparator, and wiring connecting the resistor to the wire interface and to a first input of the comparator. The microcontroller may provide a test signal to the resistor, and a threshold signal to a second input of the comparator. The test signal passes through the resistor and continues to the wire connector and the comparator first input with little to no change or attenuation when the wire interface is disconnected, but is attenuated when the wire interface is connected to a wire with capacitance charging and discharging based on the test signal. The comparator may compare the voltage of a resulting signal at the wire interface to the threshold signal voltage, and depending on the comparison may detect if a wire is connected to the wire interface.
