  • Patent number: 10389348
    Abstract: A temperature protection device includes temperature detection devices detecting the temperatures of switching elements and a control device controlling the switching elements. The control device stops driving of a first switching element the temperature of which rises to an overheat detection temperature and resumes the driving of the first switching element when the temperature of the first switching element drops to a return temperature. The control device controls timing of resuming the driving of the first switching element so that an undriven time period of the first switching element is longer in a case where at least one of the switching elements other than the first switching element is in a high load state when the temperature of the first switching element reaches the overheat detection temperature than that in a case where all the switching elements other than the first switching element are in a low load state.

    Abstract: A grille shutter is a device configured to adjust a temperature of coolant water of an engine by adjusting an amount of outside air introduced into a radiator of the engine. An ECU performs a failure diagnosis for the engine based on a temperature of coolant water of the engine. When the grille shutter is immovable in an opened state of the grille shutter regardless of an operating command to the grille shutter, the ECU renders the failure diagnosis process for the thermostat valve not to be executed. As a result, an incorrect operation of various controls executed based on a temperature of coolant water of the engine can be suppressed.

The system includes at least one slave temperature sensor embedded at preset positions for measuring temperature of a block and a master temperature sensor embedded in an integrated circuit chip and electrically connected to each slave temperature sensor. Variations of the slave temperature sensor induced by variations of process, voltage and temperature are corrected by the master temperature sensor. Thus the area the temperature sensors required on the integrated circuit chip is dramatically reduced and the stability of the temperature control system is improved. The problem of conventional System-on-a-Chip that only a limited number of temperature sensors could be used due to the area they occupied can be solved.

  • Patent number: 9442170
    Abstract: In an embodiment, a circuit is configured to produce a magnetic field signal having a frequency spectrum. The circuit may also produce a temperature signal. A modulation circuit may modulate the temperature signal with a frequency outside the frequency spectrum of the magnetic field signal. The modulated signal and the magnetic field signal may be combined to produce a combined signal. A separation circuit may be configured to separate component signals from the combined signal. The separation circuit may include a first filter, which, when applied to the combined signal, produces a filtered signal; a modulation circuit configured to shift the data representing the temperature signal to a baseband frequency; and a second filter configured to separate the data representing the temperature signal from the combined signal.

  • Patent number: 9429484
    Abstract: The invention relates to a method for determining the heat flow (dQ/dt) emanating from a heat transporting fluid (12), which is a mixture of at least two different fluids, and which flows through a flow space (11) from a first position, where it has a first temperature (T1), to a second position, where it has, due to that heat flow (dQ/dt), a second temperature (T2), which is lower than said first temperature (T1), whereby the density and specific heat of said heat transporting fluid (12) is determined by measuring the speed of sound (vs) in said fluid, and said density and specific heat of said heat transporting fluid (12) is used to determine the heat flow (dQ/dt).

    Abstract: A temperature characteristic correction device corrects a temperature characteristic of an electronic device. The temperature characteristic correction device calculates a peak correction characteristic approximating a peak waveform having a peak value in a second range included in a first range of the temperature characteristic using a first formula, and a correction characteristic approximating a waveform continuing in the first range of the temperature characteristic using a second formula. The temperature characteristic correction device calculates a total correction amount from the peak correction characteristic and the correction characteristic, and then corrects the temperature characteristic using the total correction amount.
