The application of a radio frequency ball bearing cage temperature telemeter in a high speed turbocharger is demonstrated. A temperature dependent LC tank circuit is adhered to the bearing cage and wirelessly monitored using an axially displaced stationary receiver coil. The cage sensor is installed in a turbocharger rotor-bearing system and is able to withstand the harsh conditions of being tested...
This research presents the first wireless temperature sensor for bearing condition monitoring, capable of operating through thick metal (greater than 18-mm thick) plates. The sensor is a combination of a ring-shaped permanent neodymium magnet and a Hall Effect sensor. Based on the temperature-induced change in the magnetic field, the sensor is able to detect bearing temperature remotely from a distance...
This paper presents an innovative sensor system, created specifically for new civil engineering structural monitoring applications, allowing specially packaged fiber grating-based sensors to be used in harsh, in-the-field measurement conditions for accurate strain measurement with full temperature compensation. The sensor consists of two fiber Bragg gratings that are protected within a polypropylene...
The detection sensitivity of <0.50 ppb-m of HF gas is achieved with CW GaSb-based DFB lasers at 2396 nm. Sensitivity was characterized over laser operating temperature and output power.
In current systems-on-chip (SoC) designs, managing peak temperature is critical to ensure operation without failure. Our novel communication architecture based thermal management (CBTM) scheme manages thermal behavior of components by delaying the execution of chosen IP-blocks or components by regulating the flow of data over the on-chip communication bus. This temperature aware traffic flow over...
Increased operating temperatures of chips have aggravated leakage and reliability issues, both of which are adversely affected by high temperature. Due to thermal diffusion among IP-blocks and the interdependence of temperature and leakage power, we observe that the floorplan has an impact on both the temperatures and the leakage of the IP-blocks in a system on chip (SoC). An increase in temperature...
