A learning unit learns a difference between a detected value ECT and a detected value RCT when it is determined that the detected value ECT and detected value RCT are stable while an engine is at a stop. A diagnostic unit performs a fault diagnosis for the engine based on the difference between the detected value ECT and detected value RCT having been corrected through use of a learned value learned by the learning unit. Accordingly, a fault diagnostic system for an internal combustion engine and a fault diagnostic method for an internal combustion engine can be achieved in which accuracy in fault diagnosis for the internal combustion engine can be improved and an erroneous diagnosis can be restrained.

A sensor system that can be used to analyze structures associated with aerial vehicles using one or more radio frequency (RF) or microwave frequency signals. For example, the sensor system can be used to analyze an aerial vehicle structure to detect metal fatigue, micro-cracks, thermal stress, defects, deformations, and other possible indicators of overstress and/or failure. The aerial vehicle structures that can be analyzed are any structures associated with or used on an aerial vehicle, whether propelled by one or more turbine engines, by one or more propellers, one or more rocket engines, or other forms of propulsion.

Disclosed herein is a test rover apparatus, a test system and a test method using the test rover apparatus. For example, the test rover apparatus is provided with a chassis that is configured to support an object representing a mobile actor, and a motor that is coupled to at least one wheel. At least one spring is coupled between the at least one wheel and the chassis to: bias the at least one wheel to extend out of the cavity to engage an underlying surface, and compress in response to a load being applied to the top of the chassis thereby retracting the at least one wheel into the cavity. A controller is configured to control the motor to drive the at least one wheel to propel the chassis along a predetermined route that is based on simulation data and corresponds to a maneuver of the mobile actor.

A modular pavement slab comprises a body, a strain sensor array, and a sensor processor. The body includes a top surface, a bottom surface, and four side surfaces. The modular pavement slab is configured to be coupled to at least one other modular pavement slab via connectors along at least one of the side surfaces. The strain sensor array is retained within the body and is configured to detect a plurality of strains on the body resulting from vehicular traffic across the top surface of the body. The sensor processor is in communication with the strain sensor array. The sensor processor is configured to communicate input signals to the strain sensor array, receive output signals from the strain sensor array, and determine a plurality of time-varying strain values, each strain value indicating a strain experienced over time by a successive one of a plurality of regions of the body.

An abnormality detecting apparatus includes a signal obtaining unit, a first index calculation unit, a spectrum calculation unit, a standardization unit, and a second index calculation unit. The signal obtaining unit obtain signals indicating a rotation speed of the wheel assembly, as pulses having a rise. The first index calculation unit calculates a first index indicating a temporal variation of the rise of each of the pulses. The spectrum calculation unit calculates a frequency spectrum of rotational orders from a first order to an mth order of the first index calculated for each of the pulses. The standardization unit standardizes a gain for each rotational order of the frequency spectrum using a mean value and a standard deviation of the gain for each rotational order when there is no abnormality. The second index calculation unit calculates a second index for determining whether there is an abnormality.

A system for testing braking and steering systems of a vehicle includes a steering actuator to cause rotation of the steering wheel and electropneumatic modules associated with each wheel brake that include a solenoid controlling fluid communication between a brake actuator of the wheel brake and one of a fluid source and atmosphere. A controller transmits a first control signal to an electropneumatic module associated with a wheel brake on one side of the vehicle to actuate the solenoid of the electropneumatic module. The controller transmits a second control signal to the steering actuator to cause rotation of the steering wheel during actuation of the solenoid of the electropneumatic module and in a rotational direction towards the same side of the vehicle.

Methods and systems for transmitting data from an aircraft engine. A plurality of input signals are received at a control device, during an operation of the aircraft engine, from one or more sensors of the aircraft engine, one or more actuators of the aircraft engine, or any combination of the one or more sensors and the one or more actuators. The plurality of input signals are combined, at the control device, into an output signal indicative of the operation of the aircraft engine. The output signal is transmitted, at the control device, to a controller located remotely from the aircraft engine.
