GEAR TO SEARCH FOR GEOPATIC ZONES Russian patent published in 2001 - IPC

FIELD: medicine and agriculture. SUBSTANCE: gear deals with search and location on ground surface of zones caused by anomalies in distribution of water-bearing horizons and layers with various chemical composition negatively effecting health, being and behavior of men and animals which can lead to pathological state of health and illnesses. Gear includes square frame carrying first, second, third and four electrodes fixed in its angles, first subtracter whose inputs are connected to first and third electrodes, second subtracter whose inputs are connected to second and fourth electrodes, third subtracter whose inputs are connected to outputs of first and second subtracters, fourth subtracter whose inputs are connected to outputs of first and second storages and fifth subtracter whose inputs are connected to outputs of third and fourth storages. Outputs of fourth and fifth subtracters are connected to inputs of second indication unit. Gear also incorporates adder 24 whose inputs are connected to outputs of first and second subtracters and whose output is connected via first analog-to-digital converter to one of inputs of first indication unit. Output of third subtracter 8 is connected via second analog-to-digital converter to another input of first indication unit and controlling inputs of both analog-to-digital converters are connected to one of outputs of control unit whose another output is connected to sweep generator and whose third output is connected to controlling inputs of all storages and commutator. Another input of commutator 18 is connected to one of outputs of sweep generator, third input of it is connected to output of current meter. First, second, third and fourth outputs of commutator are connected to proper electrodes. Another output of sweep generator is connected to input of current meter and one output of current meter is connected via third analog-to-digital converter to inputs of all storages. EFFECT: increased accuracy and convenience of search and location of geotactic zones. 2 dwg
