    Abstract: A thermostat diagnostic apparatus is provided with a cooling medium temperature sensor, an engine operating condition sensor and a malfunction diagnosing device. The malfunction diagnosing device is configured to diagnose a stuck-open malfunction of a thermostat provided in a coolant flow passage of an engine installed in a mobile body based on a comparison of a real cooling medium temperature detected by the cooling medium temperature sensor and an estimated cooling medium temperature estimated based on an engine operating condition of the engine detected by the engine operating condition sensor. The malfunction diagnosing device determines that the thermostat is stuck in an open state upon determining that either the estimated cooling medium temperature or the real cooling medium temperature exceeds a prescribed reference value during a period in which an increased heat exchange rate condition of a radiator is satisfied continuously.

  • Patent number: 8725430
    Abstract: A correlation is preliminarily obtained between a depth of damage and a ratio between a temperature gradient in temperature distribution on a surface of an area containing the damage and a temperature difference between a maximum temperature and a minimum temperature in the temperature distribution. The temperature distribution on the surface of the area containing the damage in the structure is then measured. Once the temperature distribution on the structure surface is obtained, attention is focused on temperature distribution between two points including the damaged area, so that a temperature difference between a maximum temperature and a minimum temperature in the distribution is obtained, and further a temperature gradient of an interval exhibiting temperature variation equal to or higher than a predetermined level is obtained.

  • Patent number: 8717183
    Abstract: A leak detector for detecting and locating leaks in a water supply pipe of plastics, the leak detector comprising a first sensor at a first position arranged to detect a leak signal travelling along a pipe, a second sensor arranged to detect a leak signal travelling along the pipe at a second position spaced from the first position, and a processing device adapted to receive the signals from the first sensor and the second sensor. The processing device may be adapted to determine the velocity of the signals from characteristics of the leak signals. The processing device is adapted to use the velocity and distance between the first sensor and the second sensor to determine the location of a leak. The characteristics may be the relationship between the phase and frequency of the leak signals.

  • Patent number: 8708554
    Abstract: A leak detection apparatus for aircraft bleed air systems includes a supporting spacer positioned within the shroud and supported upon the bleed air duct of the aircraft. A sleeve supported on the exterior of the shroud further supports a plenum having generally cylindrical sensor tubes through which sensor wire sets pass. A director positioned within the shroud above the bleed air duct is coupled to a generally cylindrical accumulator which in turn is in communication with the plenum. Appropriate apertures are provided to vent and direct bleed air from the shroud interior to the sensor wire sets and thereafter vent outwardly into cooler ambient air. The sensor wire sets respond to the temperature of the bleed air leakage to trigger alarm apparatus.

  • Patent number: 8702303
    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.

  • Patent number: 8696196
    Abstract: A bleed leakage detection system includes an arrangement of thermostats that are capable of detecting the place where the bleed air leakage is occurring (e.g., the failed junction in bleed air duct work). The exemplary illustrative non-limiting implementation provides a bleed leakage detection system with continuous monitoring of thermostat sensor wiring during flight and thermostat self-test function (“Initiated Built In Test”—“IBIT”). The IBIT self-testing can be initiated before the aircraft takes off or optionally, during periodic self testing that may be run during predetermined periods such as overnight when the aircraft is not being flown. By the continuous monitoring the pilot is alerted when a bleed leakage has occurred or when the bleed leakage detection system has failed.
