Abstract: A system includes a navigation apparatus and controller. The navigation apparatus includes a body assembly that includes a plurality of pneumatic or artificial muscles that are configured to interact with a sidewall of the conduit and move the body assembly through the conduit. The plurality of pneumatic or artificial muscles are independently actuated to steer the body assembly. The navigation apparatus also includes a sensor array coupled to the body assembly. The sensor array is positioned to interact with the sidewall of the conduit and provide signals as the body assembly moves through the interior cavity. The controller is communicatively coupled to the sensor array and configured to determine a characteristic of the conduit based on the signals provided by the sensor array.

Abstract: A navigation apparatus for use in navigating a pipe having a sidewall defining an interior cavity is provided. The navigation apparatus includes a body assembly having a first end and a second end and configured to move through the interior cavity of the pipe. The navigation apparatus also includes a channel defining a fluid passageway extending at least partly between the first end and the second end of the body assembly, an inlet for fluid from the interior cavity of the pipe to enter the fluid passageway, and an outlet for the fluid to exit the fluid passageway and return to the interior cavity of the pipe. The channel is configured to allow the fluid to flow through the fluid passageway and from the first end of the body assembly to the second end of the body assembly as the body assembly moves through the interior cavity of the pipe.

Abstract: A tunneling device includes a body assembly, an expander coupled to the body assembly and extending along a longitudinal axis, and a tip coupled to the expander. The expander is disposed between a force transmitter and the tip. The expander is expandable in a direction perpendicular to the longitudinal axis between a first configuration having a first width measured perpendicular to the longitudinal axis and a second configuration having a second width measured perpendicular to the longitudinal axis. The tip has a width measured perpendicular to the longitudinal axis. The first width of the expander is equal to or less than the width of the tip. The force transmitter is configured to deliver a force through the expander to the tip to move the tip in a direction parallel to the longitudinal axis with the expander in the second configuration.

Abstract: A seal monitoring apparatus is provided. The seal monitoring apparatus includes a temperature sensor and a controller in communication with the temperature sensor. The temperature sensor is mounted at a seal of a device. The controller is configured to receive measured temperature data from the temperature sensor and calculate expected temperature data for the seal based at least in part on operating conditions of the device. The controller is configured to determine a condition of the seal based at least in part on a temperature difference of the measured temperature data from the expected temperature data.

Abstract: A system for use in servicing a turbomachine, the system including a first tubular body including an interior channel, and a second tubular body. The first and second tubular bodies are bendable between a neutral shape and a biased shape. The bodies are bent when in the neutral shape. The second tubular body includes a tip end, and the second tubular body is translatable within the interior channel. The first tubular body and the second tubular body are rotatable to selectively orient the tip end in multiple degrees of freedom. The system also includes a steering cable extending from the tip end, wherein the steering cable biases the tip end for selective orientation in additional degrees of freedom.

Abstract: A seal assembly for a rotary machine is positioned between a rotating component and a stationary component of the rotary machine. The seal assembly includes a seal bearing face that opposes the rotating component and a slide device. The slide device is positioned between different fluid pressure volumes in the rotary machine. The slide device axially moves toward the rotating component responsive to pressurization of the rotary machine. The slide device includes cross-over ports and the seal bearing face includes feed ports. The feed ports extend through the seal bearing face to form an aerostatic portion of a film bearing between the seal bearing face and the rotating component. The seal bearing face and/or the rotating component is a non-planar surface that, during rotating motion of the rotating component, forms an aerodynamic portion of the film bearing between the seal bearing face and the rotating component.
