  • Patent number: 11652722
    Abstract: The embodiments described herein can dynamically adjust timing of network bandwidth estimations by adjusting a target frequency for sending probing sequences to one or more receivers of content. The receivers receive these probing sequences from a transmitter and respond to the transmitter with network bandwidth estimations. In one embodiment, the probing sequences can use the content itself to create the probing sequences. The embodiments can be used in video conferencing applications to control how a transmitter of content can adjust transmissions based upon the network bandwidth estimations. In one embodiment, a policy can be used at a transmitter to begin a video transmission with a high frequency target for sending probing sequences (with, e.g., smaller length probing sequences) and transition to a lower frequency target (with, e.g., longer length probing sequences) when network bandwidth deteriorates and then return to the higher frequency target when the network bandwidth improves.

  • Patent number: 10606919
    Abstract: We present a system that performs prognostic surveillance operations based on sensor signals from a power plant and critical assets in the transmission and distribution grid. The system obtains signals comprising time-series data obtained from sensors during operation of the power plant and associated transmission grid. The system uses an inferential model trained on previously received signals to generate estimated values for the signals. The system then performs a pairwise differencing operation between actual values and the estimated values for the signals to produce residuals. The system subsequently performs a sequential probability ratio test (SPRT) on the residuals to detect incipient anomalies that arise during operation of the power plant and associated transmission grid. While performing the SPRT, the system dynamically updates SPRT parameters to compensate for non-Gaussian artifacts that arise in the sensor data due to changing operating conditions.

  • Patent number: 10339784
    Abstract: A sensor data stream is provided consisting of feature vectors acquired by sensors of rotating equipment, similar feature vectors are aggregated in microclusters. For newly arriving feature vectors, a correlation distance measure between the new feature vector and each microcluster is calculated. If there is no microcluster in range, then a new microcluster is created. Otherwise, the feature vector is assigned to the best fitting microcluster, and the necessary statistical information is incorporated into the aggregation contained in the microcluster. In other words, similar feature vectors are aggregated in the same microclusters. The microclusters thus provide a generic summary structure that captures the necessary statistical information of the incorporated feature vectors. At the same time, the loss of accuracy is quite small. Clustering the sensor data stream with microclusters has the benefit that the computational complexity can be reduced significantly.

  • Patent number: 9218486
    Abstract: When using intrusion detection systems, security specialists are concerned with false positive rates and true positive rates. False positives are when an alert is raised, but no actual intrusion occurs. True positives are when an alert is raised for an actual intrusion. Ideally, true positive rate is 1 and false positive rate is zero, but such a situation is impossible in the real world. So one must balance a true positive rate and a false positive rate to produce the best result at the best price. One can simplify the choice of detection sets by, instead of determining each possible operating point of the information detection system, by only choosing operating points that are not dominated by other operating points.

  • Patent number: 8990961
    Abstract: Determination of non-linearity of a positioning scanner of a measurement tool is disclosed. In one embodiment, a method may include providing a probe of a measurement tool coupled to a positioning scanner; scanning a surface of a first sample with the surface at a first angle relative to the probe to attain a first profile; scanning the surface of the first sample with the surface at a second angle relative to the probe that is different than the first angle to attain a second profile; repeating the scannings to attain a plurality of first profiles and a plurality of second profiles; and determining a non-linearity of the positioning scanner using the different scanning angles to cancel out measurements corresponding to imperfections due to the surface of the sample. The non-linearity may be used to calibrate the positioning scanner.

  • Patent number: 8904872
    Abstract: The present invention relates to a method of detecting non-linear operation of a measuring device comprising an array of transducers and at least one receiver channel portion. The method comprises receiving measured signals through transducers of the array, processing the measured signals from the transducers through the receiver channel portion, combining the processed measured signals to produce a combined measurement signal, and detecting non-linearity of the combined measurement signal and non-linear operation of the measuring device by detecting saturation of the receiver channel portion. In one embodiment, the receiver channel portion comprises an analog-to-digital converter, a threshold is assigned to a digital output of the analog-to-digital converter, and saturation of the receiver channel portion is detected when the digital output of the analog-to-digital converter oversteps the assigned threshold. In one application of the invention, the measuring device is a non-destructive testing device.

  • Patent number: 8862425
    Abstract: A sensing and control system terminates a cycle test when it senses the part being cycle tested is about to fail. The sensing and control system uses a sensor for generating a signal each time the test part completes a motion cycle. The sensing and control system uses a controller, responsive to the sensor, for determining whether a failure is about to occur and stopping the cycle test.

  • Patent number: 8849603
    Abstract: A method of testing a component of a mobile platform without using an aircraft control system of the mobile platform, where the component forms a part of the aircraft control system. The method may involve using a test controller independent of the aircraft control system to initiate a test operation. The test operation is used to generate a test signal. The test signal is applied to a test subsystem carried on the mobile platform but operable independent of the aircraft control system. The test subsystem is used to act on the component of the aircraft control system. A response of the component may then be evaluated.

  • Publication number: 20140278195
    Abstract: In a method for operating a medical imaging system and a medical imaging system operating according to such a method, a measurement sequence is divided into a number of partial sequences, with each of the partial sequences resulting in a loading of at least one of these system components when the measurement sequence is executed. The partial sequences are evaluated, in terms of their number and duration, using a computerized model in order to determine whether a load limit for the at least one of the system components is exceeded. If so, the number or duration of the partial sequences is modified, and a check using the computer model is again implemented. A number or respective duration of the partial sequences that results in the load limit not being exceeded is then used as a final output in order to operate the medical imaging system.
