  • Patent number: 11668765
    Abstract: A detection circuit and an integrated circuit. The detection circuit is used for detecting the drift or an open circuit of a first capacitor (C1) on a filtered second power source terminal (220), and the second power source terminal (220) is suitable for acquiring a power source voltage from an unfiltered first power source terminal (210) by means of a first resistor (R1), and is suitable for being coupled to a reference electric potential terminal (230) by means of the first capacitor (C1). The detection circuit comprises a second resistor (R2) and a second capacitor (C2) that are connected in series and coupled between the first power source terminal (210) and the reference electric potential terminal (230), wherein the second resistor (R2) and the second capacitor (C2) have the same time constant as the first resistor (R1) and the first capacitor (C1).

  • Patent number: 11515585
    Abstract: A method for accurately measuring a battery temperature using a temperature sensor embodied in a battery monitoring integrated circuit is disclosed. The method includes performing calibration to estimate a thermal resistance between the battery monitoring integrated circuit and a terminal of a battery, measuring a temperature using the temperature sensor, measuring a voltage at the terminal or at a supply pin of the battery monitoring integrated circuit while a current is being used to charge or discharge the battery, calculating a power by multiplying the voltage and the current, and calculating a self-heating temperature adjustment to the temperature by multiplying the power and the thermal resistance.

  • Patent number: 10826138
    Abstract: Method and apparatus for contact detection in battery packs are disclosed. The battery pack may comprise at least a first battery cell and a second battery cell, and a power bar for coupling a first electrode of the first battery cell to a second electrode of the second battery cell. The first battery cell comprises a supervisor, which comprises a transmitter/receiver for signal communication with the second battery cell via a communication wire, and a voltage difference detector coupled to the power bar and the communication wire, for detecting a voltage difference between the power bar and the communication wire. The supervisor may indicate degraded contact of the power bar if the detected voltage difference is out of a predetermined threshold range. A battery cell and a method for monitoring a battery pack are also disclosed.

  • Patent number: 9319984
    Abstract: A wireless receiver is activated periodically to measure the level of received signals. It measures the average received level over a plurality of the activation periods, and enables the supply of power to receiver circuitry dependent on the measured average value. In one embodiment the power is enabled if an increase in the average value is detected which is greater than a predetermined margin. The average value may be measured in a sliding or stepped window. In another embodiment the power is enabled if the level in an activation period exceeds the average value by a predetermined margin.

  • Patent number: 8694274
    Abstract: In summary, the invention relates to a device, a system, a method and a computer program for spectrum sensing. A detection procedure for detecting a signal of interest or an event by using a plurality of sensing devices capable of communicating with a central unit is proposed. The sensing devices can compute soft detection metrics and communicate this information to a central unit, where the information may be used to make a final detection decision using a certain specified rule. The signaling overhead of the proposed approach can be of the same order as that of a hard signaling approach. However, the proposed approach may achieve a better detection performance.
