ULTRASOUND ANTENNA GRID Russian patent published in 2017 - IPC G01N29/22 

FIELD: radio engineering, communication.

SUBSTANCE: ultrasonic antenna array containing ultrasonic transducers installed in the housing with a dry point contact on the working surface of the grate, an individual clamping mechanism with the possibility of reciprocating movement perpendicular to the working surface of the grate and the control circuit. The transducers are arranged in plan along a zigzag line with contact points at its vertices, the vectors of the vibrational displacements of all ultrasonic transducers are oriented transversely or along the longitudinal axis of the antenna array, permanent magnets placed on the working surface of the array are additionally installed, the control circuit is made in the form of an amplifier and a pulse generator for Each converter, a common control unit, a signal processing device, and a communication unit. The output of each pulse generator is connected to the input of the corresponding converter and the input of the corresponding amplifier whose output is connected to the corresponding information input of the signal processing device, the input of the pulse generator is connected to the corresponding output of the control unit, the synchronizing output of which is connected to the input of the signal processing device connected, as well as And a control unit, with a communication unit whose output is an output of the antenna array associated with the processing and display device and formation.

EFFECT: providing the possibility of creating a device with the ability to control products with both small transverse dimensions and products with a double extension.
