  • System and method to delay closure of a normally closed electrical circuit
    Patent number: 6635834
    Abstract: A system and method are provided to delay closure of an electrical circuit of a battery-powered electrical device, intended to operate remotely in an environment in which the pH value changes from one value to another. More specifically, two electrical contacts, at least one being movable, of a normally closed electrical circuit, connecting a battery in series with a battery-powered electrical device, are separated by a material that holds the circuit open until the device is exposed to an environment having a specified pH value. Exposure of the material to an environment having that specified pH value causes the material to dissolve. The dissolving of the material causes the circuit to close, energizing the device.
