  • Self-passivating metal circuit devices for use in a submerged ambient environment
    Patent number: 12586737
    Abstract: One example includes a circuit device for use in a submerged ambient environment. The circuit device includes at least one input electrical contact configured to receive an electrical input. The circuit device also includes at least one output contact configured to provide an electrical output. The circuit device further includes at least one electrical conductor associated with an electrical function of the circuit device. Each of the at least one input electrical contact, the at least one output contact, and the at least one electrical conductor are formed at least in part from one of a variety of self-passivating metals. The at least one input electrical contact, the at least one output contact, and the at least one electrical conductor are exposed to the submerged ambient environment.
    Type: Grant

  • Method and system for calibrating ESA, distributed waveform generator and receivers in sub-arrays
    Patent number: 7468690
    Abstract: A system for calibrating waveform generators and receivers of non-overlapping electronic scanning antennas includes a first sub-array, a second sub-array and a calibration cable. The first sub-array includes a first waveform generator, a first receiver, and a first switch assembly. The second sub-array includes a second waveform generator, a second receiver, and a second switch assembly. The calibration cable is configured to selectably form a common calibration path between the first and second sub-arrays based on a position of the first and second switch assemblies. The first and second switch assemblies are configured to enable calibration of the second receiver using an input from the first waveform generator via the calibration cable.
