Abstract
An expandable apparatus may comprise a tubular body, a valve piston and a push sleeve. The tubular body may comprise a fluid passageway extending therethrough, and the valve piston may be disposed within the tubular body, the valve piston configured to move axially downward within the tubular body responsive to a pressure of drilling fluid passing through a drilling fluid flow path and configured to selectively control a flow of fluid into an annular chamber. The push sleeve may be disposed within the tubular body and coupled to at least one expandable feature, the push sleeve configured to move axially responsive to the flow of fluid into the annular chamber extending the at least one expandable feature. Additionally, the expandable apparatus may be configured to generate a signal indicating the extension of the at least one expandable feature.
