Abstract: In some embodiments, a database cluster to cluster synchronization system may include multiple replicators coupled to a source database cluster and a destination database cluster, where the source and destination cluster may be shard clusters. Each of the multiple replicators may correspond to a respective subset of the source database cluster and configured to monitor changes of data on the respective subset of the source database cluster and translate the changes of data to one or more database operations to be performed on the destination cluster. The changes of data on the source database may be contained in respective change streams associated with each of the replicators.

Abstract: A crustacean butchering apparatus is disclosed. The crustacean butchering apparatus may include at least one carapace grip sized to secure a carapace of a crustacean to a conveyor. When activated, the conveyor carries the crustacean secured by the carapace grip in a machine direction along a processing path. A plurality of tools may be placed along the processing path for butchering the crustacean. Optionally, a claw removing tool may be positioned along the processing path. When activated, the claw removing tool separates at least one claw of the crustacean from the carapace of the crustacean. Optionally, a tail removing tool may be positioned along the processing path. When activated, the tail removing tool may separate a tail of the crustacean from the carapace of the crustacean.

Abstract: A method and apparatus of packing product in a tubular casing is provided. The method includes providing a continuous length of tubular casing, providing an expansion plug within the tubular casing, grasping the casing upstream end with a casing grabber, moving the casing grabber away from the expansion plug towards an outlet end of a product feed conduit, feeding product from the product feed conduit through the casing upstream end into the tubular casing, and cutting the tubular casing downstream of the product to sever an upstream casing segment from the remaining continuous length of tubular casing.

Abstract: A workstation controller includes a processor. A memory, a first drive control output, a first current sensor, and one or more user operable controls are each communicatively coupled to the processor. When the workstation controller is communicatively connected to a first drive controller that operates at least a first workstation actuator, the processor is configured to (i) receive, from the first current sensor, a first current reading of electrical current flowing from the first drive controller to the first workstation actuator, and (ii) in response to the processor determining that the first current reading exceeds a predetermined current threshold associated with obstructive interference, transmit to the first drive controller, by way of the drive control output, one or more commands to operate the first workstation actuator to perform a safety protocol stored in the memory.

Abstract: An apparatus for removing meat from crustacean legs includes a conveyor, and a plurality of leg meat extraction rollers. The conveyor has a plurality of leg slots arranged in a machine direction, each leg slot extending laterally in a cross-machine direction. The leg meat extraction rollers are positioned adjacent the conveyor laterally outwardly of the leg slots and oriented to receive crustacean legs moved laterally outwardly from the leg slots.

Abstract: An apparatus for processing a crustacean body part is disclosed. The apparatus includes a conveyor, a first blade, and a first fluidic device. The conveyor has a downstream direction and a first region for supporting a crustacean body part. The first fluidic device is drivingly coupled to the first blade, and actuation of the first fluidic device moves the first blade into the first region. Methods of processing a crustacean body part, methods and apparatus for cracking a crustacean shell, controllers for directing processing of a crustacean body part, and pre-cut seafood items are also disclosed.
