  • Patent number: 9989424
    Abstract: Thermoacoustic sensors, such as dynamic pressure sensors, in the combustor measure vibratory responses of the combustor. An integrated monitoring and control system controller correlates sensor readings with combustion thermoacoustic properties in order to identify combustion anomalies by wavelet or Fourier analysis techniques; determine bulk temperature characteristics within the combustor with dominant mode frequency analysis techniques; and optionally determines absolute active path temperatures within the combustor with acoustic pyrometry transmission and time-of-flight analysis techniques. In some embodiments all of the monitoring functions are performed with a commonly shared array of thermoacoustic sensors that function as both combustion dynamics thermoacoustic vibration/wave receivers and acoustic transmitters. The monitored combustion properties are used for controlling gas turbine combustion.

  • Patent number: 9747564
    Abstract: A system and method for analyzing aircraft operation and maintenance history in light of maintenance reports, aircraft type system failure history, health management reports, and aircraft exterior structural conditions to produce a real time recommendation regarding aircraft maintenance and dispatch. A visual inspection report is generated by capturing a real time image of an exterior of the aircraft, inverting the real time image, superimposing the real time image on a previous image of the aircraft exterior, and detecting any variation on the combination of superimposed inverted image on the previous image of the aircraft exterior. Aircraft type historical systems failure reports are analyzed to identify any predictive latent system failure of the aircraft based on the aircraft type historical systems failure report and aircraft operation history and maintenance history.

  • Patent number: 9739720
    Abstract: A method, a computer system and an apparatus are disclosed for inspection recipe generation for the automated inspection of semiconductor devices. In order to generate the inspection recipe a reference data set is used. Automatic inspection is carried out with an initial recipe on images of dies of the reference data set (reference wafermap). The detected inspection results from the automatic inspection are classified and the classified inspection results are compared with an expert classification of defects in dies. Overkill and underkill numbers are automatically generated. According to the overkill and underkill numbers the inspection recipe parameters are modified. Automatic inspection is repeated if the detection and/or the classification are below a predefined threshold.

  • Patent number: 9664649
    Abstract: A method to acquire the structural health state of an aircraft mechanical component performs measurements at each frequency point of interest by using a network of transducers and working each one simultaneously as actuator and sensor. Each transducer is individually excited by a sinusoidal, constant frequency and arbitrary amplitude, voltage waveform for each arbitrary frequency point used to interrogate the structure. A dedicated hardware executes an analogical (analog) quantization to measure electrical current and average electrical power consumed by each transducer. With these two variables, the electromechanical signature of the structure is obtained at different areas of the monitored structure.

  • Patent number: 9638436
    Abstract: A monitoring system for a heating, ventilation, and air conditioning (HVAC) system of a building includes a monitoring device installed at the building, a monitoring server located remotely from the building, and a review server. The monitoring device measures an aggregate current supplied to components of the HVAC system and transmits current data based on the measured aggregate current. The monitoring server receives the transmitted current data and, based on the received current data, assesses whether failures have occurred in first and second components of the HVAC components. The monitoring server generates a first advisory in response to determining that the failure has occurred in the first component. The review server provides the first advisory to a technician for review and, in response to the technician verifying that the failure has occurred, transmits a first alert.
