<p>An inflation verification system for an inflatable tool includes at least an information collector associated with the inflatable element of the inflatable tool connected to a controller with a predetermined set of instructions for inciting communications with the surface. Communicators contemplated include atmospheric chambers which when opened create a negative pressure pulse which propagates to the surface. More than one chamber increases the number of pulses generable and thus the amount of information conveyable. Alternative preferable communicators are electromagnetic pulse generators and acoustic telemetry. An advantage of acoustic telemetry is that more quantitative information is transmittable. Other downhole communication methods are also employable.</p> |
