Electromagnetic fields - Import export

For reducing losses, in high-frequency or pulse-field applications, electromagnetic coils can be designed using dielectric materials for their frames. Also the winding can be made of multi-strand high-frequency cable.

Electromagnetic system with a high field uniformity in the working volume ~ 1 cm3. It can be used for calibration of different types of magnetometers. Low power consumption allows continuous operation without cooling in the field range of ± 50 mT. The system can be controlled by a computer. Basic technical parameters: - overall dimensions - 280 × 340 × 340 mm; - net weight - ~ 95 kg; - maximal magnetic field induction - 50 mT; - the field inhomogeneity in the operating region - 0.01 - 0.05 %; - power consumption - ~ 200 W; - PC control mode, including the polarity reversal, is available.

The compact system of permanent magnets NdFeB, designed according to the principle of the dipole Halbachstructure, allows to get, inside the bore, rather homogeneous magnetic field with the magnetic flux density up to 23 Tesla. The system can be an efficient alternative to electromagnetic sources of the magnetic field, and can be used in scientific and applied research requiring magnetic fields of high intensity. Geometrical dimensions and magnetic flux density in Halbachtype systems can vary widely, the attached data and photos are typical examples. AMT&C LLC offers the manufacturing of steady magnetic field systems according the customer technical specifications. To improve the temperature stability the system can be assembled of SmCo magnets.

The work of the TempoHeart module is based on the method of scoring the heart rate vegetative regulation. This method is popular due to its high information value and non-invasiveness. Cannot be used without an interface block. The module can: • evaluate the heart rate autonomic regulation; • to predict in advance (to prematurely reveal) the hazards of a myocardial infarction, hypertensive crises and strokes; • to determine the metabolic and electrolyte disorders in the myocardium; • identify risk groups for heart rate increased stability; • to make a cold evaluation of the autonomic nervous system's reaction when exposed to electromagnetic fields, intoxications and other pathogenic factors; • to assess the activity of the respiratory component when measuring heart rate variability, recording the parameters of blood movement in the vessels; • to expose the stress resistance level.
