摘要： Two adjacent objects with a gap between the objects rotate in a hot atmosphere with a temperature greater than 300 F in a gas turbine. Automatic and accurate contactless measurement of the gap is performed by taking images of the gap. An image, preferably an infra-red image is taken from the gap, a processor extracts the two edges from the image of the gap. The processor also determines a line through the pixels of an edge by applying a Hough transform on the pixels. The edges are substantially parallel. A line substantially perpendicular to the lines is also determined. Using the substantially parallel lines and the line substantially perpendicular to the substantially parallel lines the processor determines a width of the gap.

摘要： A controller includes a ramp signal generator and control circuitry coupled to the ramp signal generator. The ramp signal generator provides a control current through a resistive component to control energy stored in a first energy storage component. The ramp signal generator further generates a ramp signal based on the energy stored in the first energy storage component. The control circuitry adjusts a voltage at one end of the resistive component thereby controlling the control current to indicate a voltage across a second energy storage component. The control circuitry further controls a current through the second energy storage component within a predetermined range based on the ramp signal.

摘要： Deep Neural Network (DNN) training technique embodiments are presented that train a DNN while exploiting the sparseness of non-zero hidden layer interconnection weight values. Generally, a fully connected DNN is initially trained by sweeping through a full training set a number of times. Then, for the most part, only the interconnections whose weight magnitudes exceed a minimum weight threshold are considered in further training. This minimum weight threshold can be established as a value that results in only a prescribed maximum number of interconnections being considered when setting interconnection weight values via an error back-propagation procedure during the training. It is noted that the continued DNN training tends to converge much faster than the initial training.
