Abstract: A variable ram packer includes a body with a bore contact region, at least one fluidic flexible matrix component (FFMC) tube, an inflation mechanism, and a fluid port. The FFMC tube is positioned inside the body next to the bore contact region. The fluid port is fluidly coupled with a connecting line, which is fluidly coupled with the inflation mechanism. The FFMC tube inflates in response to an increase in pressure from the inflation mechanism, which translates the bore contact region inward.

Abstract: A variable ram packer includes a body including two contact regions. The first contact region includes a region of the body of the packer that includes a first material and a second material, layered on top of one another. The first material has an elastic modulus less than that of the second material. The second contact region includes the second material and a third material, layered on top of one another. The third material has an elastic modulus greater than that of the second material, but less than that of the first material.

Abstract: A seal assembly at a rotor-stator interface includes at least one non-contacting seal interface and at least one rub detection feature. The rub detection feature(s) is configured to generate a signal upon the rotor and the stator making contact at the rotor-stator interface and causing wear above a certain threshold at the rotor-stator interface. The seal assembly also includes at least one sensor arranged at the rotor-stator interface. The sensor is configured to sense the signal. The seal assembly further includes a controller communicatively coupled with the sensor(s). The controller is configured to receive the signal and estimate at least one of an amount and a location of the wear at the rotor-stator interface based on the signal.

Abstract: A system includes a tunneling device including a body assembly configured to move through an interior cavity of a tunnel. The system also includes a distributed communication and sensing system and a controller. The distributed communication and sensing system includes a first beacon coupled to the body assembly, and a second beacon positioned outside of the tunnel. The second beacon is communicatively coupled to the first beacon. The controller is configured to compare a first signal transmitted by the first beacon to a second signal transmitted by the second beacon, determine an environmental characteristic of the tunnel based on the first signal and the second signal, and determine an operating parameter for the tunneling device based on the environmental characteristic.
