  • Patent number: 11201400
    Abstract: The beamforming system includes a plurality of beamformers operatively coupled to each other. Each beamformer includes a plurality of signal generation units and a plurality of respective delaying units. Each beamformer includes a plurality of multipliers assigned to each delaying unit. Each beamformer includes a plurality of summers configured to receive a respective group of conditioned signals from a respective group of the plurality of multipliers, combine the respective group of conditioned signals and generate a respective phased array output signal. Each of the summers is configured to receive at least another input other than the respective group of conditioned signals. The plurality of beamformers are interconnected such that each of the plurality of summers within each beamformer receives, as the at least another input, a respective phased array output signal from a summer of a different one of the plurality of beamformers. As associated method is also provided.

  • Patent number: 9666941
    Abstract: A beamforming system comprising a plurality of modular beamformers is provided. The modular beamformers may be operatively coupled to each other (for example, in parallel). Each modular beamformer may comprise a plurality of signal generation units configured to generate signals. Each modular beamformer may further comprise a plurality of delaying units configured to receive the signals and adaptively delay output of the signals. Each modular beamformer may further comprise a plurality of multipliers assigned to the delaying units to generate conditioned signals by adaptively applying weights to the signals output by the plurality of delaying units. Each modular beamformer may further comprise a plurality of summers configured to combine the conditioned signals to generate a phased array output signal.

  • Patent number: 5507184
    Abstract: In the process whereby a time gate but especially the time gate for an expected error range 58 in a device by means of which materials are tested by ultra sound according to the impulse echo process involving a test head 20 which emits pulses that impinge diagonally on the surface 28 of a test piece 24, the test head 20 that emits diagonally is firmly connected to a test head 22 from which pulses are emitted vertically. Both test heads emit at given intervals 48, 49 ultra sound impulses and subsequently receive them. The echo signal 50 of the entry of sound of the test head 22 from which pulses emit vertically is utilized to activate the time gate of the test head from which sound is emitted diagonally.
