  • Patent number: 10302811
    Abstract: A data reduction method for transmission of a borehole image to the surface of the earth using restricted band widths of LWD telemetry systems. The data reduction method is based on the measurement physics rather than mathematical compression algorithms. Measured data from a sensor are fitted, within the logging tool, to a response function relating sensor response to a parameter of interest. The coefficients of the fitted response function are scaled and then telemetered to the surface. The measured data are reconstructed at the surface by combining the telemetered coefficients with the response function. A borehole image is formed by combining reconstructed reduced data. Parameters of dipping beds intersecting the borehole can be determined from the coefficients.

  • Patent number: 10254873
    Abstract: The embodiments described herein provide devices and methods that facilitate improved performance. In one embodiment, an input device comprises a plurality of capacitive sensor electrodes and a processing system coupled to the electrodes and configured to operate the electrodes to sense in a sensing region. Specifically, the processing system is configured to determine information about input objects in the sensing region based on comparisons of preliminary values with corresponding baseline values. The processing system is further configured to selectively operate in a first mode and a second mode. While operating in the first mode, the processing system selectively changes a baseline value of the plurality of baseline values by a first amount in response to that baseline value being below a corresponding preliminary value. This selective changing of baseline values occurs even when the processing system determines that an input object is in the sensing region.

  • Patent number: 10240924
    Abstract: A surveying system for surveying and tracking a movable target object that defines a target point includes a surveying device with a sighting unit defining a target axis and a detector for generating a continuously current amount-of-deviation signal dependent on a deviation from an optimal target orientation. A second unit on the target object side enables continuous determination of movements and/or positions of the target object with reference to an external coordinate system. The surveying system includes a target point tracking mode in which respective first measurement data currently generated by the first unit and the respective current amount-of-deviation signal and respective second measurement data currently generated by the second unit are continuously aggregated. On the basis thereof, a control signal is derived for continuous automatic motorized modification of the target axis orientation such that the target axis continuously aims at the target point.

  • Patent number: 10139434
    Abstract: A system measures the stability of a live a.c. power distribution grid, without disrupting sensitive loads on that grid. The system applies repetitive time-synchronized loads to create current pulses, and resulting voltage instabilities, on the grid. The current pulses are sized to ensure that the resulting voltage instabilities are too small to affect the sensitive loads. Time-synchronized voltage measurement devices record the voltage instabilities. The time synchronization, and the repetitive nature of the current pulses, allow the voltage instabilities caused by the current pulses to be extracted from the larger background voltage variations.

  • Patent number: 8000930
    Abstract: The present disclosure is concerned with the identification of fault origins of slowly degrading systems such as industrial gas turbines. Following the initial input of some parameter values, exemplary procedure comprises a number of steps which are repeated periodically during the operation of the gas turbine. First, for each potential fault such as e.g. a contamination of compressor blades, erosion of turbine blades or corrosion of machine parts, a pre-symptom fault probability, characteristic of the specific gas turbine considered, and a symptom-conditional fault probability are calculated. In a second step, on-line data from the monitoring devices are loaded in order to update information about symptoms such as e.g. reductions in polytropic efficiency and in flow capacity, changes in vibration spectrum, or other machine condition indicators, and a post-symptom fault probability is calculated.

  • Patent number: 7970559
    Abstract: Methods, systems, and articles of manufacture consistent with the present invention determine the type of damage to a wire, the amount of damage, and the location of the damage based on the wire's broadband impedance measured from a single measurement point. The type of damage is determined by comparing the wire's calculated dielectric function, resistance and inductance to known values that correspond to types of wire damage. The amount of damage is determined by comparing the wire's low-frequency impedance phase to known low-frequency impedance phase information that corresponds to a known amount of wire damage. The location of damage is determined by comparing the wire's high-frequency impedance phase to known high-frequency impedance phase information that corresponds to a known location of wire damage.
