Abstract: There is provided a measuring apparatus for measuring a signal-to-noise ratio of a discrete waveform which is output from an AD converter in response to an input signal, where the signal-to-noise ratio indicates a ratio of a signal component of the input signal to noise generated by the AD converter. The measuring apparatus includes a spectrum compensating section that receives a spectrum of the discrete waveform output from the AD converter, and compensates the received spectrum in accordance with a non-symmetric sideband between an upper sideband and a lower sideband of the received spectrum, where the upper and lower sidebands are defined with respect to a fundamental frequency of the input signal, and a phase noise waveform calculating section that calculates a phase noise waveform of the discrete waveform based on the spectrum which has been compensated by the spectrum compensating section.

Abstract: A refracture-candidate diagnostic test is an injection of compressible or slightly compressible fluid at pressures in excess of minimum in-situ stress and formation fracture pressure with pressure decline following injection test recorded to detect a fracture retaining residual width from previous stimulation treatments. The diagnostic consists of small volume injections with injection time being a small fraction of time required for compressible or slightly compressible reservoir fluid to exhibit pseudoradial flow. The fracture-injection portion of a test can be considered as occurring instantaneously. Data measurements are transformed into a constant rate equivalent pressure transformation to obtain adjusted pressures or adjusted pseudovariables which are analyzed to identify dual unit-slope before and after closure periods confirming a residual retaining width.

Abstract: A method of checking turbomachine blades is presented that may be implemented using a computer and a measuring device. Turbomachine blades compatible with embodiments of the method have a profile including a centerline, suction face, pressure face, leading edge and trailing edge. The method measures geometrical coordinates of many points on a blade section profile, calculates an aerodynamic parameter of the blade section as a function of the measured coordinates, verifies whether the calculated aerodynamic parameter value departs from a valid range of parameters from a reference blade, and validates or rejects the blade depending upon whether the value of the aerodynamic parameter falls within the valid range.

Abstract: In an integrated circuit with at least two separate timing circuits, for example both a serializer and a deserializer, a trim value correction factor is developed and applied at the testing of the chip. The correction trim value brings the VCO frequency of the serializer into specifications, but the trim value may also be used to alter the delay between a received clock and data in the deserializer. Since both the serializer and the deserializer were made with the same process, the received clock delay may be corrected by substantially the same correction factor as that applied to the VCO. Illustratively the trim values may be stored on the IC.

Abstract: A system and method for obtaining weather related information for a portion of the Earth's atmosphere between a predetermined surface portion of the Earth and an airborne object located over the predetermined surface portion, and operating at a known altitude, using position locating signals from a space vehicle. In one exemplary implementation the space vehicle transmits a first position locating signal. The first position locating signal is received by the airborne object directly from the space vehicle. A second position locating signal from the space vehicle is received by the airborne object after being reflected from the predetermined surface portion at a known angle. Phase information from the first and second position locating signals is used to determine a refractivity of the atmosphere between the predetermined surface portion and the airborne object. The refractivity is used to determine weather related information for the atmosphere.

Abstract: Based on the time series data from multiple components, the systems administrator or other managing entity may desire to find the temporal dependencies between the different time series data over time. For example, based on actions indicated in time series data from two or more servers in a server network, a dependency structure may be determined which indicates a parent/child or dependent relationship between the two or more servers. In some cases, it may also be beneficial to predict the state of a child component, and/or predict the average time to a state change or event of a child component based on the parent time series data. These determinations and predications may reflect the logical connections between actions of components. The relationships and/or predictions may be expressed graphically and/or in terms of a probability distribution.

Abstract: The present invention provides a method for detecting the start of a dive for a portable electronic device (1) comprising a pressure sensor (5) for measuring the value of the ambient pressure (P) as well as electronic circuits (2) for processing the pressure measurement results comprising a time base (4) and at least one memory zone (7, 8). The detection method updates the reference pressure value (Pref) on the basis of ambient pressure (P) measurements, this value being used to detect the start of a dive. In certain particular conditions, the method according to the present invention suspects the start of a dive, and backs up the value (Psauv) of the reference pressure (Pref) stored before updating. If the start of a dive is confirmed after having been suspected, the reference pressure value (Pref) stored is replaced by the backed up value (Psauv) upon activation of the dive mode.

The P wave incident angle is referred to herein as ?. The method may further include calculating the density contrast based on the converted wave reflection coefficient at ?.

Abstract: According to an inventive scheme for introducing a watermark into an information signal, the information signal is at first transferred from a time representation to a spectral/modulation spectral representation). The information signal is then manipulated in the spectral/modulation spectral representation in dependence on the watermark to be introduced to obtain a modified spectral/modulation spectral representation, and subsequently an information signal provided with a watermark is formed based on the modified spectral/modulation spectral representation. An advantage is that, due to the fact that the watermark is embedded and/or derived in the spectral/modulation spectral representation or range, traditional correlation attacks as are used in watermark methods based on a spread-band modulation cannot succeed easily.
