  • Patent number: 10752085
    Abstract: A temperature sensor for a vehicle that is designed to detect an interior temperature of the vehicle and that can be arranged in the vehicle. The temperature sensor provides improved usability and can be manufactured more easily. In particular, the temperature sensor allows raw data of the temperature sensor to be evaluated by the temperature sensor itself. An advantage of this setup thus is that a tedious sensor-specific adaptation of an associated control device in the vehicle for evaluating the raw data is not necessary. Different temperature sensors can be used with the control device without the control device having to be adapted in a different way to each of these temperature sensors.

  • Patent number: 9827845
    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.

  • Patent number: 9797829
    Abstract: A method for assessing damage to a composite material covered with a polyurethane-type paint is provided. Two separate criteria are measured on a spectrogram obtained by infrared spectrometry, thereby characterizing thermal ageing of the paint, each separate criteria being a measurement on a curve of a spectrum of the spectrogram of a height of a particular peak, thereby giving two independent assessments of the thermal ageing. Then, the two separate criteria are combined together in order to obtain a result of a level of the damage.

  • Patent number: 9726556
    Abstract: A method for calibrating a temperature sensor arranged in a vapor compression system is disclosed. The opening degree of an expansion device is alternatingly increased and decreased. Simultaneously a temperature of refrigerant entering the evaporator and a temperature of refrigerant leaving the evaporator are monitored. For each cycle of the opening degree of the expansion device, a maximum temperature, T1, max, of refrigerant entering the evaporator, and a minimum temperature, T2, min, of refrigerant leaving the evaporator are registered. A calibration value, ?T1, is calculated as ?T1=C?(T2, min?T1, max) for each cycle, and a maximum calibration value, among the calculated values is selected. Finally, temperature measurements performed by the first temperature sensor are adjusted by an amount defined by ?T1, max.

  • Patent number: 9714872
    Abstract: A solid thermal simulator sensing device, the device can simulate and sense the thermal characteristics of a perishable element and is easily calibrated to a verifiable standard. The device is fabricated from a single piece of solid material sized to have a thermal mass substantially equal to that of said perishable element. A sensing channel is located within the single piece of solid material. The sensing channel extends from one end towards the center. A temperature sensor is mounted within the sensing channel. The thermal response time of the device is slowed by the single piece of solid material to mimic the thermal properties of the perishable element. A calibration channel is extends from the outer surface of the device to a point adjacent the temperature sensor. A calibration probe may be inserted into the calibration channel to quickly verify the accuracy of the device.
