The present disclosure relates to a multi-plunger lift control device for increasing device durability and production efficiency by synchronizing and controlling operating states of a plurality of plunger lifts sharing some production lines. The multi-plunger lift control device according to the present disclosure includes a plunger lift synchronization setting unit configured to set an operation priority of the plurality of plunger lifts so that production stages of the plurality of plunger lifts do not collide, a stage monitoring unit for each plunger lift configured to monitor current production stages of the plurality of plunger lifts, and a plunger lift logic control unit configured to synchronize and control production operations of the plurality of plunger lifts based on the operation priority set by the plunger lift synchronization setting unit and stage monitoring information received from the stage monitoring unit for each plunger lift. The multi-plunger lift control device according to the present disclosure can increase device durability and production efficiency by synchronizing and controlling operating states of the plurality of plunger lifts in an environment that shares a production line for transporting oil and/or gas produced in a plurality of oil and/or gas wells, in which the plurality of plunger lifts are installed, to a remote storage.

A method for performing the translation type mapping in the No. 7 gateway signaling network includes defining translation type information on a non-local signaling network in a translation type mapping table according to a manager's request; mapping a translation type of the non-local signaling network contained in the SCCP message received by the neighboring (adjacent) non-local signaling network by searching the translation type mapping table; and mapping a translation type of a local signaling network contained in the SCCP message transmitted to the adjacent non-local signaling network into the translation type of the non-local signaling network by searching the translation type mapping table.

An ultrasound imaging system using a knowledge-based image adjusting device, which enables to obtain the optimal ultrasound image by automatically adjusting image parameters on the basis of pre-stored patient information so that operating procedures required of a system operator are reduced. The ultrasound imaging system comprises a patient information recording medium; a reference image database for storing reference image parameters; a similarity calculation unit for comparing patient information and corresponding reference image parameters and determining the parameter with the highest similarity; and an image adjusting block for selecting a type of probe and automatically adjusting image settings of the selected probe. The ultrasound imaging system further comprises a user input device for inputting and adjusting degrees of freedom parameters.
