SEMICONDUCTOR MANUFACTURING APPARATUS AND TEMPERATURE CONTROL METHOD
A semiconductor manufacturing apparatus includes: a gas introduction pipe connected to a processing container of the semiconductor manufacturing apparatus in order to introduce a gas into the processing container; and a temperature sensor provided in the gas introduction pipe in order to measure a temperature of a gas in the gas introduction pipe.
CONTROL SYSTEMS FOR USE IN CRITICAL POWER APPLICATIONS
A method includes receiving temperature measurements from multiple temperature sensors in a power supply system that includes multiple coils arranged in a series downstream of a turbine, each coil configured to receive thermal energy from an air stream exhausted from the turbine as the air stream moves toward a data center, each coil associated with at least one fluid loop. The method also includes using a first subset of the temperature measurements to determine a blended fluid mix from a primary fluid path and a heated fluid reservoir in order to obtain a predetermined leaving fluid temperature at a first coil of the multiple coils. The method further includes controlling a position of one or more valves associated with the primary fluid path and the heated fluid reservoir to achieve the determined blended fluid mix.

TURBINE INLET TEMPERATURE CALCULATION USING ACOUSTICS
A method of determining a turbine inlet temperature for a gas turbine engine includes measuring pressure changes within a combustion section of the gas turbine engine during operation of the gas turbine engine to produce pressure versus time data, extracting a resonant frequency from the pressure versus time data, and calculating the turbine inlet temperature based solely on the resonant frequency.

ADJUSTING FOR AIR FLOW TEMPERATURE CHANGES IN AN ASPIRATING SMOKE DETECTOR
Methods, devices, and systems for adjusting for air flow temperature changes in an aspirating smoke detector are described herein. In some examples, one or more embodiments include a blower configured to cause air to flow through the aspirating smoke detector, and a controller configured to determine a temperature of the air flowing through the aspirating smoke detector has changed by a particular amount and adjust a speed of the blower in response to compensate the air flowing through the aspirating smoke detector that has changed by the particular amount.
Sensor assemblies, gas turbines with sensor assemblies, and methods of cooling sensor assemblies
A sensor assembly includes a housing defining a potting chamber and arranged along a sensor axis, a mounting flange extending about the sensor axis the axially offset along the sensor axis from the housing, and one or more intermediate flange. The one or more intermediate flange is arranged between the housing and the mounting flange along the sensor axis, the one or more intermediate flange coupling the mounting flange to the housing. The one or more intermediate flange is spaced apart from mounting flange to limit thermal communication between the mounting flange and the housing. Gas turbine engines and methods of cooling sensor assemblies are also described.
