  • Patent number: 9267209
    Abstract: Systems and methods are described for controlling the current of a sacrificial anode based on the conductivity state of the water. An unregulated current of the sacrificial anode relative to the water tank is measured and a conductivity state of the water is identified based on the measured unregulated current. A maximum current limit for the sacrificial anode is determined based on the conductivity state of the water and the current of the sacrificial anode is limited such that the current does not exceed the determined maximum current limit.

  • Patent number: 9248894
    Abstract: A controlled corrosion release system for a payload is provided. The payload is submerged in a conductive medium, such as seawater. The system includes clips which restrain the payload against a housing. A circuit is established to allow electrical current to flow from a power source contained within the housing, through the clips which serve as anodes, through the seawater, into the housing which serves as a cathode, and back to the power source. Accordingly, the clips corrode and weaken structurally. The clips eventually fail and the payload is released. The time for release is proportional to the power supplied, such that the release time can be controlled.
