  • Patent number: 10803733
    Abstract: A method for managing voltage event alarms in an electrical system includes processing electrical measurement data from energy-related signals captured by at least one intelligent electronic device (IED) of a plurality of IEDs to identify an anomalous voltage condition at a point of installation of a respective one of the plurality of IEDs in the electrical system. In embodiments, the anomalous voltage condition corresponds to a measured IED voltage being above one or more upper alarm thresholds or below one or more lower alarm thresholds. The method also includes determining if the electrical system is affected by the identified anomalous voltage condition. In response to determining that the electrical system is not affected by the identified anomalous voltage condition, at least one of the one or more upper alarm thresholds or at least one of the one or more lower alarm thresholds may be adjusted to the measured IED voltage.

    Abstract: A method is disclosed to secure the operation of a vehicle. To detect any tampering during the communication of information or command, encrypting and authenticating devices are placed on the two ends of a communication channel. On the first end, an encryption device generates a first packet by encrypting the information using a random variable. The first packet and the information are communicated to the second end of the communication channel. On the second end, the authenticating device generates its own packet by encrypting the information using the random variable; then it compares the two packets and pronounces the information authentic if the two packets are identical. Any tampering with the information or the first packet will be detected and blocked by the authenticating device. Secured sensor and secure actuator are also provided.

  • Patent number: 10701523
    Abstract: A mobile device includes a receiver receiving a radio wave from a wireless communication device, a transmitter transmitting an authentication signal when the radio wave that is received requests transmission of the authentication signal, a vibration detector detecting whether there is vibration, and an operation controller bringing the mobile device into a communication enabled state where the receiver and the transmitter are in operation when the vibration is detected, and bringing the mobile device into a communication disabled state where at least one of the receiver and the transmitter is stopped when the vibration is not detected. When the radio wave is received in the communication enabled state, the operation controller brings the mobile device into a communication enabled continuous state where the receiver and the transmitter are in operation even if the vibration is no longer detected.

  • Patent number: 10680299
    Abstract: This patent provides a battery heating technique that preheats the battery from extreme cold condition (e.g., ?30° C.) to an appropriate operating temperature. This technique belongs to the battery energy storage and application field. The battery heating system includes a simple external control circuit and a battery (or battery pack) for heating. During the heating stage, the external control circuit and battery (or battery pack) forms a close loop. A continuous and pulse current will flow through the battery and generate joule heat on the battery internal resistance to preheat the battery (or battery pack). The heating technique can be used on any types of batteries without changing their internal and external structures, and this technique is low cost and can preheats the battery (or battery pack) from ?30° C. to 0° C. in one minute. By using the internal resistance as the heat source, the heating technique can heat the battery (or battery pack) uniformly and is of high efficiency.

  • Patent number: 10680452
    Abstract: Various systems and methods for implementing zero-power mode are described herein. A battery-powered apparatus includes a non-removable battery for powering processing circuitry of the apparatus, charging pins to connect the apparatus to a charging source, and control circuitry that is separate from the processing circuitry. The control circuitry can perform operations that detect the charging pins are shorted and activate a timer for a predetermined wait interval. The control circuitry can also, upon expiration of the timer, disconnect the battery from powering the processing circuitry to activate a device zero-power mode. Upon detecting the charging pins are no longer shorted, the control circuitry can resume power to the processing circuitry. The non-removable battery is only powering the control circuitry while the battery is disconnected from the processing circuitry.
