    Abstract: A system includes a robot device that comprises a non-transitory computer readable medium and a robot controller. The non-transitory computer readable medium stores one or more machine-specific modules comprising base neural network layers. The robot controller receives a task-specific module comprising information corresponding to one or more task-specific neural network layers enabling performance of a task. The robot controller collects one or more values from an operating environment, and uses the values as input to a neural network comprising the base neural network layers and the task-specific neural network layers to generate an output value. The robot controller may then perform the task based on the output value.

  • Patent number: 10041859
    Abstract: A profile map of parameter values in a region is determined based on average values along linear paths through the region. In one example, a temperature map of a region of a gas turbine engine is created based on time-of-flight measurements from acoustic transceiver pairs arranged circumferentially around the region. A speed of sound for each transceiver pair is determined based on the time-of-flight measurements. An average temperature along each path is estimated from the time of flight, and the profile map is computed from the average temperatures. The profile map may be computed using a polynomial approximation technique, a grid optimization technique or a basis function technique.

  • Patent number: 9945737
    Abstract: A method for determining waveguide temperature for at least one waveguide of a transceiver utilized for generating a temperature map. The transceiver generates an acoustic signal that travels through a measurement space in a hot gas flow path defined by a wall such as in a combustor. The method includes calculating a total time of flight for the acoustic signal and subtracting a waveguide travel time from the total time of flight to obtain a measurement space travel time. A temperature map is calculated based on the measurement space travel time. An estimated wall temperature is obtained from the temperature map. An estimated waveguide temperature is then calculated based on the estimated wall temperature wherein the estimated waveguide temperature is determined without the use of a temperature sensing device.

  • Patent number: 9927325
    Abstract: Techniques for determining temperature and velocity in a space inside a gas turbine engine (100) include mounting acoustic sensors (150) in the engine. The sensors are mounted to detect acoustic signals in a space (108) of fluid flow without extending into the space. A first sensor (350a) is displaced a first distance (351) from a different second sensor (350b) in a first direction parallel to fluid flow through the space. First and second signals are detected at the first and second sensors, respectively. A travel time difference between the first and the second sensors is determined by control system (170) module (180) based on the first and second signals. Velocity of fluid flow in the space is determined by the module based on the travel time difference. Temperature of fluid flow in the space is determined by the module based on either the first or the second signals or both.

  • Patent number: 9746360
    Abstract: Performance of a gas turbine engine is monitored by computing a mass flow rate through the engine. Acoustic time-of-flight measurements are taken between acoustic transmitters and receivers in the flow path of the engine. The measurements are processed to determine average speeds of sound and gas flow velocities along those lines-of-sound. A volumetric flow rate in the flow path is computed using the gas flow velocities together with a representation of the flow path geometry. A gas density in the flow path is computed using the speeds of sound and a measured static pressure. The mass flow rate is calculated from the gas density and the volumetric flow rate.
