  • Publication number: 20200165934
    Abstract: A method for determining an arrival-time of a rotor blade that includes attaching an RF reader to a stationary surface and an RF tag to the rotor blade. Time-of-flight data points are collected via an RF monitoring process that includes: emitting an RF signal from the RF reader and recording a first time; receiving the RF signal at the RF tag and emitting a return RF signal by the RF tag in response thereto; receiving the return RF signal at the RF reader and recording a second time; and determining the time-of-flight data point as being the duration occurring between the first time and the second time. The RF monitoring process is repeated until multiple time-of-flight data points are collected. A minimum time-of-flight is determined from the multiple time-of-flight data points, and the arrival-time for the rotor blade is determined as being a time that corresponds to the minimum time-of-flight.

  • Publication number: 20200166432
    Abstract: A method for determining an arrival-time of a rotor blade in a turbine engine that includes the steps of: having an RF reader attached to a stationary surface in the turbine engine; having an RF tag attached to a first region of the rotor blade; having a reference RF tag attached to a rotating structure near the RF tag; in relation to a first revolution of the rotor blade occurring during the operation of the turbine engine, collecting an arrival-time for each of the RF tag and the reference RF tag with the RF reader via an RF monitoring process; comparing the arrival-time of the RF tag to the arrival-time of the reference RF tag to determine an arrival-time test result for the first region of the rotor blade for the first revolution.

  • Publication number: 20200166431
    Abstract: A method for determining an arrival-time of a rotor blade that includes attaching an RF reader to a stationary surface and an RF tag to the rotor blade. Strength-of-signal data points are collected via an RF monitoring process that includes: emitting an RF signal from the RF reader; receiving the RF signal at the RF tag and emitting a return RF signal by the RF tag in response thereto; receiving the return RF signal at the RF reader; measuring a signal strength of the return RF signal as received by the RF reader; and determining the strength-of-signal data point as being equal to the measured signal strength. The RF monitoring process is repeated until multiple strength-of-signal data points are collected. A maximum strength-of-signal is determined from the multiple strength-of-signal data points, and the arrival-time for the rotor blade is determined as being a time that corresponds to the maximum strength-of-signal.

  • Publication number: 20190207010
    Abstract: An integrated circuit having silicide block integrated with CMOS transistors is formed by forming a silicide block layer of primarily silicon dioxide, free of silicon nitride and silicon oxy-nitride, at less than 400° C. prior to annealing the PMOS sources and drains. A spike anneal process concurrently anneals the PMOS sources and drains and densifies the silicide block layer. The NMOS drain junctions are less than 120 nanometers; the NMOS halo regions include boron. The NMOS and PMOS transistors are laterally separated by an STI oxide layer. A wet deglaze process prior to metal silicide formation removes less than 25 percent of the silicide block layer, and exposes sides of the NMOS drains less than 20 percent of the drain junction depth. The metal silicide does not extend down the NMOS drains sides, directly adjacent to the STI oxide layer, more than 20 percent of the drain junction depth.

    Abstract: A fuse-programmable register or memory location having a plurality of fusible links of differing electrical characteristics in parallel. In one embodiment, three fusible links with different resistances are provided, such that application of a programming voltage non-uniformly distributes the current among the links, allowing varying voltages to selectively blow one or more of the links. Sensing of the programmed state is performed by applying a voltage across the parallel links and measuring the current in comparison with a plurality of reference currents. Reduction in the overhead chip area per bit and in the serial data communication latency are obtained.

  • Publication number: 20140161612
    Abstract: A tip shroud of a bladed rotor can be monitored for integrity using a sensor configured to detect the tip shroud. A signal from the sensor can be monitored and if the magnitude of the signal changes, such as beyond a defined amount, an indication of possible damage can be made. A baseline sensed pattern for a revolution of the tip shroud can be compared to an operation sensed pattern for a subsequent revolution, and the indication of damage can be made if there is more than the defined amount and/or percentage of difference between the patterns.
