A power supply for plural loads coupled in parallel comprises a voltage regulator, a plurality of current regulators, and an error control circuit. The voltage regulator provides a common output voltage to the plural loads. The voltage regulator comprises a sensor circuit providing a voltage sense signal corresponding to the output voltage, which provides feedback to regulate the output voltage at a selected level. The plurality of current regulators are coupled to respective ones of the plural loads. Each of the plurality of current regulators regulates current drawn by respective ones of the plural loads to within a desired regulation range. The plurality of current regulators each further provide a respective error signal corresponding to an ability to remain within the desired regulation range. The error control circuit is operatively coupled to the voltage regulator and to the plurality of current regulators. The error control circuit receives the error signals from the plurality of current regulators and provides a common error signal to the voltage regulator. The voltage regulator thereby changes the selected level of the output voltage in response to the common error signal. Accordingly, the selected level of the output voltage remains at a minimum voltage necessary to keep the plural loads in the desired regulation range.

The invention finds matches in ordered sequences, e.g. program function call stacks from anomalous software program executions for discovering related or identical software flaws and possible known solutions. Call stacks are matched after removing recursive and uninformative subpatterns, e.g. names of common error handling routines, to see if they were generated due to the same possibly known problem. Sequences statistically unlikely to be matches are pruned from the search. Matches found earlier in the sequences may be weighted differently, e.g. to be more important in call stacks, than other matches. Sequences are indexed so that those relevant to a query are identified automatically without detailed exhaustive search. Maximum matches are found by optimizing a cost function based on weighted sequence similarity.

This invention presents Normalized Amplitude Hilbert Transform (NAHT) and Normalized Hilbert Transform(NHT), both of which are new methods for computing Instantaneous Frequency. This method is designed specifically to circumvent the limitation set by the Bedorsian and Nuttal Theorems, and to provide a sharp local measure of error when the quadrature and the Hilbert Transform do not agree. Motivation for this method is that straightforward application of the Hilbert Transform followed by taking the derivative of the phase-angle as the Instantaneous Frequency (IF) leads to a common mistake made up to this date. In order to make the Hilbert Transform method work, the data has to obey certain restrictions.

An exemplary embodiment of the present invention is a method for testing an integrated circuit. The method includes generating a test pattern and generating a reference signature corresponding to the test pattern. An integrated circuit test is executed in response to the test pattern and a result signature is generated in response to data output from executing the integrated circuit test. The result signature is compared to the reference signature and a current failing signature is created if the two don't match. The current failing signature is copy of the result signature. Common error analysis is executed in response to creating the current failing signature. Additional embodiments include a system and storage medium for testing an integrated circuit.

The switching-type constant current power supply of the present invention can stabilize the load current even under the condition that a load (e.g. display including LEDs) is repeatedly turned on and off.

A method and apparatus are set forth for defining and validating feature policies in an execution system, such as a communication system. The method includes entering user policies described in a straightforward manner (e.g. using a Web browser and user-understandable language) in such a way that they can be translated into a formal executable language. The user policies are then translated into an executable feature language such as the IETF's CPL. The user is then either compelled or provided with an option to validate the overall feature set before it is uploaded to the execution system. If validation is selected, the features are translated from CPL into another format, such as FIAT, from which it is possible to detect common feature specification errors. The FIAT detected errors are then analyzed in a manner that is aware of the expectations and common errors of naive users, and interpreted to determine possible errors as errors that are common to naive users. These errors are reported to the user (e.g. via the Web interface) in terms that are understandable to naive users and compatible with how the policies were originally described. The user is provided with options to either accept the interactions as they are, repair them manually or to accept a recommendation of an automatic correction. Unlike conventional systems, where feature interactions are solved in the same way for all users, the selected resolution is personalized in the present invention to satisfy the end-user's intentions, independently of how others solve similar conflicts. The features are uploaded to the execution system.

The invention belongs to the fields of antenna measuring technique and satellite navigation and positioning, and relates to a correction method for the absolute antenna phase center of an outdoor GNSS (Global Navigation Satellite System) receiver based on a precision mechanical arm. In view of the problem that conventional outdoor GNSS observation cannot obtain a high-precision correction model for the absolute antenna phase center of a receiver, a majority of common errors are eliminated through ultra-short baseline observation, the absolute phase center offset (PCO) of a receiver antenna and the separation of phase center variation (PCV) are realized through rapid rotation and inclination of the high-precision mechanical arm, finally the PCO is resolved through a least squares algorithm, and fitting calculation of the PCV is carried out for observation residual. According to the correction method, outdoor operation can be carried out, the correction precision of 1mm for the PCO and PCV can be reached, the correction method is suitable for accurate calibration of the PCO and PCV of the receiver capable of tracking the signals of satellite navigation systems such as a GPS (Global Positioning System), a BDS (Beidou Navigation System), a GLONASS (Global Navigation Satellite System) and Galileo, and thus the systematic measuring error caused by imprecision of the PCO and PCV of the receiver can be eliminated, and the user positioning precision is further improved.

The invention discloses a method for real-time direction finding of a base station antenna ultrashort baseline GNSS double antenna. The two-dimensional pose of a carrier can be determined by measuringa vector fixed on the carrier.

The invention discloses a method for calibrating delay inconsistency of a radio star signal and a spacecraft signal in interferometry. Very long baseline interferometry is to use a plurality of observation stations in different geographic positions to receive a signal from a same target in the space to be processed, time delay difference from the target to two observation stations with definite positions is calculated by utilizing relevant phase and observation frequency (or bandwidth), and calibration by utilizing a radio star is a main way for eliminating common error in the very long baseline interferometry. Therefore, in interferometry, the radio star signal and the spacecraft signal are transmitted through an identical route so as to guarantee the calibration accuracy. However, because of the reasons that the characteristics of the radio star signal and the spacecraft signal are different and for improving the utilization rate of equipment and reducing the quantitative loss of the spacecraft signal, different processing ways are adopted by a system for the two signals in measurement rather than the traditional identical processing way by which the radio star signal and the spacecraft signal are transmitted through different equipment routes, and the time delay difference of the two routes needs to be precisely determined to guarantee the calibration accuracy.
