  • Patent number: 9040920
    Abstract: A method and apparatus for detecting an object. A first optical signal having a first frequency is transmitted to a location on a surface of a ground. A second optical signal having a second frequency is transmitted to the location on the surface of the ground such that the first optical signal and the second optical signal overlap each other at the location on the surface of the ground. The overlap of the first optical signal and the second optical signal at the location generates a third optical signal having a difference frequency that is a difference between the first frequency and the second frequency. The third optical signal is configured to travel into the ground. A response to the third optical signal is detected. A determination is made as to whether an object is present in the ground using the response to the third optical signal.

  • Publication number: 20150090882
    Abstract: Turbine blade tip clearance is measured in a fully assembled turbine casing by mounting a contact or non-contact displacement probe on a turbine blade that generates data indicative of probe distance from the turbine casing that circumferentially surrounds the blade. Variations in probe distance data are recorded as the blade circumferentially sweeps the turbine casing when the turbine is operated in turning gear mode. Blade rotational position data are collected by a rotational position sensor. A data processing system correlates the distance and rotational position data with localized blade tip gap at angular positions about the turbine casing circumference. An optical camera inspection system may be coupled to a turbine blade to obtain visual inspection information within the turbine casing. This method and apparatus provide an accurate and cost effective solution for accessing turbine casing deformation impact on blade tip clearance and rotor/casing alignment.

  • Patent number: RE45493
    Abstract: An image sensor system using offset analog to digital converters. The analog to digital converters require a plurality of clock cycles to carry out the actual conversion. These conversions are offset in time from one another, so that at each clock cycle, new data is available. A CMOS image sensor converts successive analog signals, representing at least a portion of an image, into successive digital signals using an analog to digital circuit block. Multiple clock cycles may be used by the circuit block to fully convert an analog signal into a corresponding digital signal. The conversion of one analog signal into a corresponding digital signal by the circuit block may be offset in time and partially overlapping with the conversion of a successive analog signal into its corresponding successive digital signal by the circuit block.
