Abstract: The invention relates to a method for filtering information emitted, on the basis of pressure measurements taken by a pressure sensor mounted on a wheel of a vehicle equipped with a tire, to a central unit mounted on the vehicle. According to this method, a value representative of the pressure of the air in the tire is measured periodically, with a period ?, and from this any possible variations ?P in pressure between the values of the pressures successively measured are deduced; in parallel, with the same period ?, a value representative of the temperature of the air in the tire is measured. In addition, when there is a variation ?P in pressure between two measured pressure values, that is greater in terms of absolute value than a predetermined threshold Sp, the variation ?T between the two temperature values measured at the same instants as the measured pressures is calculated.

Abstract: Methods for estimating data-dependent jitter (DDJ) from measured samples of a transmitted data signal include a first exemplary step of obtaining a plurality of measurements (e.g., time tags and event counts for selected pulse widths in the data signal). Such measurements may be obtained at predetermined intervals within a transmitted signal or may be obtained at randomly selected intervals, and should yield measurements for each data pulse in a repeating data pattern. An average unit interval value representative of the average bit time of the transmitted signal is determined. Time interval error estimates representative of the timing deviation from each signal edge's measured value relative to its ideal value (determined in part from the calculated average unit interval value) are also determined, as well as a classification for each measured signal edge relative to a corresponding data pulse in the repeating data pattern.

Abstract: Systems and methods for the design or implementation of statistical filters for use in the spectral shaping of transmissions are disclosed. A desired power spectrum may be mapped to find pole locations that approximate the desired spectrum. These pole locations may then be mapped to the edge or inside of an equilateral polygon lying inside a unit circle, the equilateral polygon having the same number of sides as the order of the statistical filter desired and one vertex mapped to unity, to yield a set of eigenvalues. These eigenvalues may be the eigenvalues of a stochastic matrix the elements of which may be the Markov transition probabilities for use in a statistical filter designed to achieve the desired power spectrum. Use of a statistical filter employing these Markov transition values may be utilized to shape UWB or other signals to achieve the desired power spectrum.

Abstract: One embodiment of the present invention provides a system that determines the reliability of a component in a system. During operation, the system monitors inferential variables associated with a number of specimens of the component. The system then collects degradation data by first computing a likelihood value that indicates whether an inferential variable associated with a specimen of the component is behaving normally or abnormally. Next, the system determines whether the specimen of the component has degraded based on the likelihood value. If the specimen of the component is determined to have degraded, the system records the time when the specimen of the component was determined to have degraded. The system also uses the degradation data to determine the reliability of the component in the system.

Abstract: A method, an apparatus, and a computer program are provided for the semi-automatic extraction of an ideality factor of a diode. Traditionally, current/voltage curves for diodes, which provided a basis for extrapolating the ideality factors, had to be determined by hand. By employing a thermal voltage proportional to absolute temperature (PTAT) generator in conjunction with an extraction mechanism, the ideality factor can be extracted in an semi-automatic manner. Therefore, a reliable, quick, and less expensive device can be employed to improve measurements of ideality factors.
