Abstract

A downhole device and method to trigger, shift, and/or operate a downhole device of a drilling string in a wellbore is disclosed. At a high level, the disclosed device causes a portion of drilling fluids to bypass the drill bit and into the annulus. The bypass may be triggered upon certain conditions related to the rotation speeds of the drill string or other conditions such as the pressure of the drilling fluids. For example, the drill string may be rotated in some protocol of operation (e.g., stop at certain rpm, and/or stop at certain other rpm) to describe a recognizable series of signals to an accelerometer and/or microprocessor that will communicate to pumps or valves to operate or pause/stop operations.
