Claim 16:
17. A downhole tool, comprising:
a hydraulically functioning element comprising a hydraulic piston housed in a piston housing, wherein the hydraulic piston is configured to move within the housing by hydraulic pressure, and wherein the hydraulically functioning element has an internal environment; and
an apparatus that includes:
a membrane, wherein the internal environment is disposed on a first side of the membrane and a second environment is disposed on a second side of the membrane opposite the first side, wherein the membrane is configured to isolate the internal environment from the second environment; and
an electrical element configured to conduct an electrical current, wherein the electrical element is positioned with respect to the membrane such that energy generated by the electrical current passing through the electrical element is incident on the membrane; and
wherein the membrane is configured to be weakened and/or ruptured when the energy is incident thereon to allow fluid communication between the internal environment and the second environment; and
wherein the apparatus is disposed relative to the hydraulically functioning element such that upon weakening and/or rupturing of the membrane, a fluid is released into the internal environment and at least partially operates the hydraulically functioning element.
