Abstract: Methods, apparatus, systems, and articles of manufacture are disclosed to monitor thermal degradation of a compute device. One such method includes calculating, by executing instructions with processor circuitry, a thermal degradation value based on an equation, the equation generated based on testing of thermal interface materials having varying degrees of degradation. The method also includes comparing, by executing instructions with the processor circuitry, the thermal degradation value to a thermal degradation threshold to determine whether the thermal degradation threshold is satisfied, and, when the thermal degradation threshold is satisfied, triggering generation of a thermal degradation alert.

Abstract: Multiple spatially diverse and compact weight sensors are statistically combined to reduce or eliminate errors caused by snow bridging. Data transmission using satellite communication minimizes the power consumption of the sensor station further allowing the entire system to be relatively compact and easily transported. The weight sensors may be combined with other standard sensors for measurement of air temperature and snow height, the latter measurement, for example, using ultrasound ranging or the like.

Abstract: This invention relates to a waveguide with distributed sensors that support traveling ultrasonic wave modes to provide quantitative local distributed sensing of the physical and chemical properties of the medium surrounding the sensor locations and/or the material properties of the waveguide. The plurality of sensors is operably associated with a plurality of wave modes for probing and identifying a plurality of properties simultaneously. The reflected waves are representative of local information about the surrounding media at that sensor location.

Abstract: For a gas turbine engine (10), a method and apparatus for determining temperature of combustion gas in a flow path (17) of the engine. In one embodiment a waveguide (30) includes a cavity (36) with a first waveguide end (32) including a barrier layer (58) which may be a membrane. With the first end positioned to inject an acoustic signal into the flow path, the barrier layer (58) isolates the cavity from combustion gas. Acoustic instrumentation positioned along the surface (38i) of a wall (38) of the waveguide provides generation and propagation of acoustic signals into the flow path for detection and measurement after reflection back into the cavity. The wall may include sections of two different materials, one material having a higher melting temperature than the other, or one material having greater electrically isolating properties than the other section.

Abstract: A method of measuring and controlling a temperature distribution at a member is disclosed. A probe is placed proximate the member. The probe has a plurality of longitudinally-spaced reflective elements. An ultrasonic pulse is generated at a selected location of the probe so as to propagate along the probe. Reflected pulses are received at the selected location from the plurality of longitudinally-spaced reflective elements. The distribution of temperature at the member is determined from the reflected pulses. The determined distribution of temperature may be used in controlling the temperature of the member. The member may be a solid or fluid.
