Abstract
Various technologies described herein involve apparatuses for actuating a downhole tool. In one implementation, the apparatus may include a pressure sensor for receiving one or more pressure pulses and an electronics module in communication with the pressure sensor. The electronics module may be configured to determine whether the pressure pulses are indicative of a command to actuate the downhole tool. The apparatus may further include a motor in communication with the electronics module. The motor may be configured to provide a rotational motion. The apparatus may further include a coupling mechanism coupled to the motor. The coupling mechanism may be configured to translate the rotational motion to a linear motion. The apparatus may further include a valve system coupled to the coupling mechanism. The valve system may be configured to actuate the downhole tool when the valve system is in an open phase.
