Abstract: A system for detecting leaks in vehicles comprises memory, a plurality of transducers, at least one sensor, an input device, and logic. The memory stores a plurality of transmit profiles. The transducers are disposed in a vehicle and configured to emit acoustic energy. The sensor is disposed outside of a vehicle and configured to sense the acoustic energy emitted by the transducers, and the input device is configured to receive a vehicle identifier identifying the vehicle. The logic is configured to select one of the transmit profiles for the transducers based on the vehicle identifier and to cause the transducers to emit the acoustic energy according to the selected transmit profile. The logic is further configured to detect at least one leak in the vehicle based on sample values indicative of the acoustic energy sensed by the at least one sensor and to provide an indication of the detected leak.

Abstract: The present disclosure generally pertains to systems and methods for reliably detecting leaks in sealed compartments, such as compartments within vehicles. In one exemplary embodiment, an apparatus having a sealed compartment, such as a vehicle (e.g., automobile, airplane, etc.), is moved past an array of ultrasonic sensors. An ultrasonic transmitter is placed in the sealed compartment and emits ultrasonic energy as the apparatus is moved past the ultrasonic sensors. The transmitter has a plurality of adjustable transducers allowing the transmit profile of the transmitter to be tailored as may be desired, such as based on the type of compartment being tested. A leak can be automatically and non-destructively detected by analyzing data from the ultrasonic sensors.

Abstract: The present disclosure generally pertains to a method for diagnosing a leak related problem for a vehicle. In accordance with one exemplary embodiment, the method comprises receiving, from a purchaser of a vehicle, a complaint about an operational performance of the vehicle, the vehicle having an abnormal leak; retrieving, in response to the complaint and based on a vehicle identifier identifying the vehicle, a set of data correlated with the vehicle identifier, the set of data defining a plurality of values indicative of an amount of acoustic energy sensed outside of the vehicle during a test performed on the vehicle prior to a sale of the vehicle to the purchaser, the acoustic energy emitted from at least one transducer disposed within the vehicle; analyzing the set of data retrieved in the retrieving step; and diagnosing an operational problem of the vehicle based on the analyzing step and the complaint.

Abstract: A system for enabling calibration of sensors used for detecting leaks in compartments comprising a structure, a sensor, a test manager, an arm, a transducer, and logic. The sensor is mounted on the structure, and the test manager is configured to provide an indication as to whether a compartment has an abnormal leak based on data from the sensor. The data is indicative of an amount of acoustic energy sensed by the sensor within a specified frequency range while a transmitter in the compartment is emitting acoustic energy within the specified frequency range. The arm is detachably coupled to the sensor, and the transducer is mounted on the arm. The logic is configured to cause the transducer to emit acoustic energy within the specified frequency range thereby enabling the sensor to be calibrated without removing the sensor from the structure.
