  • Publication number: 20150145467
    Abstract: A rechargeable battery temperature detection method adapted to an electronic system includes detecting a status of a processor of the electronic system when an external power is input to a power conversion module of the electronic system; determining whether a thermistor of the electronic system is conducted to a fuel gauge or a charge control circuit according to the state of the processor such that the fuel gauge or the charge control circuit determine a temperature sensing result via the thermistor. The thermistor is disposed adjacent to a rechargeable battery and has a resistance which varies with a temperature of the rechargeable battery. The temperature sensing result is related to the resistance.

  • Publication number: 20150098488
    Abstract: Systems and methods for monitoring temperature distribution in downhole equipment using magnetostrictive probes. In one embodiment, an ESP motor has a stator with a rotor and shaft rotatably positioned within the stator. Magnetostrictive sensors are positioned within the motor. Each magnetostrictive sensor has a transducer, a probe, and electronic circuitry coupled to the transducer. The circuitry generates an initial electrical signal that is conveyed to the transducer. The signal passes through one or more coils in the transducer, generating magnetic fields that induce an acoustic signal in the probe. The acoustic signal propagates through the probe and waves are reflected from reflection points in the probe.

  • Publication number: 20150092817
    Abstract: A transducer for noninvasively determining an internal temperature of a location of interest in a body of a subject may be configured to receive native temperature signals originating from the location of interest without substantially receiving interfering signals. Such a transducer may include one or more shielding features for preventing interference. In addition, such a transducer may include a dielectric cavity configured or positioned to increase the native temperature signals sensed, or received, by the antenna. A transducer may be configured to multiplex signals that are indicative of a temperature of a location of interest within the body of a subject and reference temperature signals. Such a transducer may include a connector that facilitates the communication of a multiplexed signal, such as a connector for a coaxial cable. The connector of a transducer may be configured to swivel relative to an end of a cable that has been coupled thereto. Systems including such a transducer are also disclosed.

    Abstract: An image capture device includes an image sensor. The image sensor includes a temperature sensor for measuring temperature measurements of the image sensor. A timing generator is coupled to the image sensor for applying an electronic shutter pulse to the image sensor to drain away all charge in photodiodes of the image sensing region prior to image capture. A reading component is coupled to the temperature sensor for reading the temperature measurements from the temperature sensor. The image capture device is configured to prevent erroneous temperature readings by the reading component resulting from substrate punch-through from the application of the electronic shutter pulse.

    Abstract: A temperature sensing circuit for an insulated gate bipolar transistor (IGBT) module, which enables a temperature of the IGBT module to be sensed by a pulse width modulation (PWM) method, using a photo coupler, etc., is provided. In the temperature sensing circuit for the IGBT module, a voltage value between both terminals of a diode is measured, the measured voltage value is converted into a digital signal, using a pulse width modulation (PWM) technique, and the converted digital signal is easily transmitted to a controller such as a microcomputer (MICOM), using a photo coupler for electrical insulation, so that it is possible to analyze the duty of the digital signal, thereby sensing an accurate temperature.

  • Patent number: 8961004
    Abstract: Methods and systems to determine an internal temperature of a rechargeable lithium-ion cell based on a phase shift of the cell. Internal cell temperature may be determined with respect to an internal anode temperature and/or an internal cathode temperature. Internal anode temperature may be determined based on a phase shift of a frequency within a range of approximately 40 Hertz (Hz) to 500 Hz. Internal cathode temperature may be determined based on a phase shift of a frequency of up to approximately 30 Hz. A temperature sensor as disclosed herein may be powered by a monitored cell with relatively little impact on cell charge, may be electrically coupled to cell but housed physically separate from the cell, and/or may monitor multiple cells in a multiplex fashion. A rate of change in phase shift may be used to initiate pre-emptive action, without determining corresponding temperatures.

  • Publication number: 20150049787
    Abstract: Methods and devices for mounting a sensor are presented herein. A temperature sensor assembly for a capacitor bank is disclosed that includes two opposing substrates, and a plurality of contact temperature sensors attached to each substrate. Each temperature sensor is configured to directly contact a surface of one of the capacitor cans in the capacitor bank and therefrom generate a signal indicative of the temperature of the capacitor can. A biasing member attaches the two substrates together. The biasing member is configured to selectively contract, such that the width of the sensor assembly is less than the gap distance between adjacent sets of tandem capacitor cans and the sensor assembly can insert between the sets of capacitor cans, and expand, such that the width of the sensor assembly is greater than the gap distance and the sensor assembly is tensioned against and thereby secured between the sets of capacitor cans.
