Abstract: A unidirectional transfer protocol allows data to be transmitted from a non-secure network into a secure network. A non-secure gateway may receive data and/or information, intended for the secure network, from one or more devices. The gateway may fragment the data and/or information into smaller chunks and transmit the chunks to a secure gateway via a unidirectional communication channel. The secure gateway may verify the chunks using one or more rules and reassemble the chunks when the data is validated. The reassembled data may be sent across a secure network enclave. The unidirectional transfer protocol may provide a hardware-agnostic solution for transmitting data over a unidirectional communication channel.

Abstract: A method of de-tensioning a rod by attaching a gripping unit removal device to a gripping unit and rod, positioning a chair frame over the gripping unit, positioning a rod tensioning unit along the rod with one end of the rod tensioning unit being in contact with the chair frame, applying a first force to the rod tensioning unit, positioning a bearing plate on the rod in contact with the rod tensioning unit, positioning a load cell in contact with the rod on the rod tensioning unit, securing a drive unit to the chair frame such that a portion of the drive unit is in contact with the rod, applying a second pressure to the rod tensioning unit, actuating the drive unit, and releasing the second pressure on the rod tensioning unit.

Abstract: A rod detensioning unit including a gripping unit removal device that engages a gripping unit on a rod, a chair frame configured to engage a rod, a rod tensioning unit that applies tension to an external portion of the rod to remove load from the gripping unit, a load cell unit that measures a tension level applied to the rod by the tensioning unit, a plate gripping unit that engages the rod and secures the chair frame, rod tensioning unit, load cell and plate gripping unit to the rod, a drive unit that engages the gripping unit removal device, and an extension unit affixed to the external portion of the rod when the original external rod length is too short to accommodate the de-tensioning unit.
