Abstract: A control system and method for a blowout preventer (BOP) system in an oil rig is provided. An input module generates control inputs for required components of the blowout preventer system, and transmits the control inputs simultaneously as an operational input and a numerical input, where the operational input is transmitted to the required component of the blowout preventer system. A synchronized model is coupled to the input module to receive the numerical input, and to replicate an operation of the blowout preventer system based on the numerical input. The synchronized model also generates one or more model outputs based on the replication of the operation of the blowout preventer system.

Abstract: A leak identification system for a blowout preventer (BOP) system is provided. The leak identification system includes a plurality of sensors configured to monitor one or more conditions of the BOP system and a leak detection computer device. The leak detection computer device is configured to receive at least one pressure measurement from at least one pressure sensor, receive at least one flow rate measurement from at least one flow sensor, compare the at least one pressure measurement and the at least one flow rate measurement to an algorithm, determining a leak in the BOP system based on the comparison, determine an impact to the operation of the BOP system based on the comparison and transmit the impact to the operation of the BOP system based on the comparison to a user.

Abstract: A linear oscillation system comprising a housing, a stationary assembly, a moveable assembly and a suspension system is disclosed. The suspension system is mechanically coupled between the moveable assembly and the housing. The suspension system comprises a plurality of planar elastic members and plurality of longitudinal elastic members disposed between the plurality of planar elastic members. A first end of each of the plurality of planar elastic members is mechanically coupled to at least one of the plurality of planar elastic members. A second end of each of the plurality of longitudinal elastic members is mechanically coupled to the housing.

Abstract: Washing machine appliances and damper assemblies are provided. A damper assembly includes a cylinder defining a central longitudinal axis, the cylinder including a sidewall that defines an interior, the sidewall defining a central bore and a pocket concentrically surrounding the central bore, the sidewall including an upper shoulder and a lower shoulder that each connect the pocket and the central bore. The damper assembly further includes a piston partially disposed in the central bore and movable along the longitudinal axis relative to the cylinder. The damper assembly further includes a tube assembly concentrically surrounding the piston and at least partially disposed in the pocket, the tube assembly having a length that is less than a length of the pocket. The piston is further movable along the longitudinal axis relative to the tube assembly.
