Class Information
Number: 367/12
Name: Communications, electrical: acoustic wave systems and devices > Beam stabilization or compensation
Description: Subject matter wherein the acoustic waves are received or radiated in a directional pattern and wherein means are provided to maintain a desired attitude of the pattern regardless of movement of the support for the receiving or radiating means, or wherein means is provided to counteract or neutralize undesired effects due to movement of the support for the receiving or radiating means (e.g., to correct for pitch, roll, or yaw of a vessel).
