摘要： Apparatus for implementing Adjustable Compensation Ratio (ACR) active shielding or control of physical fields (magnetic, electric, electromagnetic, acoustic, etc.), comprising the addition of a secondary internal feedback loop within a conventional primary closed feedback loop topology. Compensation-ratio transfer function order and coefficients adjustment permits accommodating frequency-dependent and frequency-independent effects within a Protected Volume when a system field sensor or sensor array is not at the exact location where external field interference must be optimally canceled. A Laplace polynomial term precisely sets this parameter in a supplementary feedback link by modeling the frequency-dependent characteristic of an Interacting Medium without deleterious effect on other desirable primary closed-loop characteristics. The inventive ACR can be used in advanced active cancellation for magnetic shielding purposes.

摘要： The present invention introduces a method for adjusting interference signal estimates provided by multichannel biomagnetic field measurements. A so-called Signal Space Separation method (SSS) is applied in the calculatory analysis of the measurement signals, providing for the division of the sources causing the fields in objects of interest and external interferences. When the signal basis representing the interferences has been estimated, this interference signal estimate is adjusted by measuring the fields without the object to be measured and without changing the sensor assembly. Interference components obtained in this manner are analyzed in such a way as to include only the most significant interference components. An adjusted interference subspace is formed, by means of which signal processing and the analysis of the useful signals can be continued.

摘要： Invention, relates to the field of supersensitive biomagnetometry under presence of external electromagnetic interferences. In order to perform passive compensation of said interferences, design of device at the magnetometer input is proposed, comprising compensation elements and means for their moving including shifting, holding, and fixation units. In the basic embodiment, three short-closed wire contours are used which are orthogonally placed in space and independently moved up-down relative to the magnetometer or its input antenna. Contours are fixed in positions where minimum of external interference amplitude is achieved according to given field projection. Variants are proposed with cooling of meter and/or contours, location of contours inside the cryostat and their manufacturing from superconductors.

摘要： An electrical connector includes one or more connector terminals, which are connected to wiring extending from the connector and are coupled to interconnect with corresponding connector terminals in a mating connector. An active shielding circuit is mounted adjacent to the connector terminals and is configured to sense a first magnetic field in a vicinity of the electrical connector and to generate, based on the sensed magnetic field, a second magnetic field that reduces interference induced in the wiring and the connector terminals by the first magnetic field.

摘要： In a magnetic data processing device, an input part sequentially receives magnetic data q i output from a magnetic sensor. A storage part sequentially stores the magnetic data received through the input part. An offset derivation part derives an offset according to a probabilistic method using a plurality of the magnetic data stored in the storage part as a statistical population. The offset derivation part assumes that an error Ap i contained in each of the magnetic data q i is a random variable v i following a probability distribution µ and uses an expected value corresponding to the probability distribution µ for deriving the offset. Specifically, the offset derivation part calculates an index representing variance of distances from the offset to respective ones of true magnetic data that are obtained by subtracting each Δp 1 from each magnetic data q i of the statistical population, and derives the offset which minimizes the expected value of the calculated index.
摘要翻译：在磁数据处理装置中，输入部顺序地接收从磁传感器输出的磁数据q i。存储部分顺序地存储通过输入部分接收的磁数据。偏移导出部件使用存储在存储部分中的多个磁数据作为统计总体，根据概率法导出偏移量。偏移导出部分假定每个磁数据q i中包含的误差Ap i是概率分布μ之后的随机变量v i，并且使用与概率分布μ对应的期望值来导出偏移。具体地，偏移导出部分计算表示通过从统计总体的每个磁数据qi中减去每个“p 1”而获得的偏移到相对于真实磁性数据的距离的方差的指标，并且导出最小化预期的偏移量计算指标的值。
