US Patent 10184308 Method and apparatus for downhole tool actuation

A downhole tool and a method for operating the downhole tool, in which the downhole tool includes a first sensing member, and a second sensing member. The first and second sensing members have a first communication status when the downhole tool is in a first configuration. The first and second sensing members have a second communication status that is different from the first communication status when the downhole tool is in a second configuration. The downhole tool is prevented from actuating prior to the first and second sensing members having the second communication status, and the downhole tool is permitted to actuate after the first and second members have the second communication status.
