Abstract: An inclination calculation apparatus calculates an inclination of an input device operable in terms of a posture thereof. The input device includes an acceleration sensor and an imaging element. In one non-limiting example implementation, the inclination calculation apparatus computes first inclination information representing an inclination of the input device based upon a coordinate position of an imaging target in an acquired image obtained by the imaging element and an estimated coordinate position of a second imaging target not acquired by the imaging element. The inclination calculation apparatus also computes second inclination information representing an inclination of the input device solely from an acceleration detected by the acceleration sensor. The inclination calculation apparatus then calculates an inclination of the input device using the first inclination information and the second inclination information.

Abstract: A method detects conflicts between a power supply guarantee request (PSGR) and an outage request (OR) in a power grid. The method comprises receiving a first outage device set including OR related devices and a power supply guarantee device set including PSGR related devices. Geographic information about devices in the power grid is used to determine a second outage device set, which includes devices in the first outage device set and accompanying outage devices that need to be in outage together with devices in the first outage device set. Power grid topology information is used to determine a power grid outage scale in which all devices in the second outage device set can be in outage. For each device in the power supply guarantee device set, the method detects whether the device is included in the power grid outage scale, to determine any conflict between the PSGR and OR.

Abstract: This invention relates to a method and device for calibrating the offset of an imaging system. The core idea of the invention is to place a reference object in the measurement chamber of the imaging system, measure the signals associated with the reference object at different points of time, calculate the merit function based on changes of the parameters representing the electromagnetic property of the reference object, and derive an optimal set of offset data that minimizes the value of the merit function for compensating the offset of the system in subsequent image reconstructions. In one embodiment, the invention uses a reference object comprising a non-conductive envelope and a cavity which can be filled with a conductive fluid and emptied, and in this way reduces the imaging interference caused by the reference object during monitoring.

Abstract: A method measures the electric power of a universal electric motor (4) connected to an electric power mains (6) by a Triac (7) and supplied by sinusoidal alternating voltage (V(t)). The method determines a first (ton) and a second (toff) instant at which the current (I(t)) supplied to the motor (4) passes from a zero value to a value other than zero. The current supplied to the motor (4) at a third instant between the first (ton) and second (toff) instant is measured. A fitting current time pattern (f(t)) approximating the real time pattern of the current (I(t)), and which has a zero current value at the first (ton) and second (toff) instant, and a current value equal to a sampled current at the third instant (tin), is determined. The mean electric power is calculated on the basis of the fitting current time pattern (f(t)).

Abstract: A rotating imaging system has a rotating portion, an idler, at least one sensor, a tilt sensor and a processor. The rotating portion has a diameter and rotates about a central axis.

Abstract: An automated emergency power supply system (EPSS) and testing solution that records generator load values and engine exhaust temperature values to evaluate whether an EPSS test satisfies legislated test criteria. The EPSS test is carried out under software control, which initiates a test by instructing an automatic transfer switch (ATS) to change its status to a test status, causing the essential loads to be powered by a generator instead of a main utility power source. Power monitors record the ATS and generator status during the test as well as electrical parameter data from the ATS and generator and exhaust temperature data and other engine parameter data from the generator. When the test is concluded, the ATS is instructed to return the status to normal so that power delivery is resumed from the main power source. The electrical and engine parameter data is analyzed and compared against legislated test criteria to determine a pass/fail result of the EPSS test.

Abstract: The invention relates to measuring visco-elastic fluid parameters, in particular, in the oil production industry, for defining heavy oil parameters during field development. The method involves the excitation of a hollow resonance device oscillations by sending a continuous variable-frequency signal to two transmitting transducers located on the outer surface the said resonance device.

Thereafter, a cavity of the said resonance device is filled with a medium under examination, and oscillations are excited to obtain associated amplitude-vs-frequency response values. An axially symmetric capacity placed in a thermostabilized chamber is used as the resonance device.

Abstract: A fixed-source array test station provides a cost-effective high-throughput test bed for testing optical sensors that require stimulus at fixed angular positions. A SAL seeker requires stimulus at fixed angular position across its FOV to calibrate its spatial transfer function (STF). An array of fixed collimated sources at different angular positions is aligned so that their beams overlap the entrance pupil of the sensor under test. Each source may comprise an inexpensive light emitting diode (LED) or vertical cavity surface emitting laser (VCSEL) and collimator. To simplify alignment the sources may be positioned on and perpendicular to the surface of a sphere with the seeker's entrance pupil located at the center of the sphere. The sources are activated in accordance with an activation profile in order to calibrate or otherwise test the sensor.

Abstract: A testing system and method for testing glass-mounted RFID tags such as tags mounted on vehicle windows. A testing carrier for use in a test chamber simulates the effect on the tag of the mounting glass. The test chamber and carrier are calibrated by first mounting the tag on the test carrier and making sensitivity measurements and then mounting the tag on glass that is representative of the actual production environment. Comparisons are made between the two measurements and calibration factors are derived to compensate for differences between the actual mounting glass and the test carrier. The test carrier is designed to provide uniform pressure against the tag to minimize any distortions that would alter the sensitivity of the tag.

Abstract: A method for attenuating pump noise in a wellbore drilling telemetry system includes spectrally analyzing measurements of a parameter related to operation of a pump used to move drilling fluid through the drilling system. Synthetic spectra of the parameter are generated based on a number of pumps in the pump system and a selected number of harmonic frequencies for each pump. Which of the synthetic spectra most closely matches the spectrally analyzed parameter output is determined. The most closely matching synthetic spectrum is used to reduce noise in a signal detected proximate the Earth's surface transmitted from a part of the drilling system disposed in a wellbore.
