摘要:
A spray nozzle (120) includes a first conduit (124) that provides a first flow path (126) for a first type of fluid, a second conduit (132) that provides a second flow path for a second fluid that is different from the first fluid, a first dispensing aperture (144) that ejects therefrom a spray (131) that includes the first type of fluid and/or the second type of fluid, and at least one balancing outlet (150a-150d) in fluid communication with the second conduit (132). The at least one balancing outlet permits (150a-150d) the second type of fluid to exit therefrom to balance a force of ejection of the spray (131) from the first dispensing aperture (144).
摘要:
Methods of protecting a metallic substrate (12) from corrosion include introducing an aqueous or powder-form composition (30) including at least one corrosion inhibitor (32) into a crevice (20) that traverses one or more layers (14, 16) covering the metallic substrate (12) to deliver the composition (30) via the crevice into contact with a surface (13) of the metallic substrate (12). The corrosion inhibitors present in the composition (30) bond to the surface (13) of the metallic substrate (12), resulting in formation of a film (34) on the surface (13) of the metallic substrate (12). This film (34) protects the surface (13) of the metallic substrate (12) against corrosion.
摘要:
A robotic arm deployment apparatus is provided for a tip following robotic arm, of the type comprising a plurality of controllable segments (34) each comprising articulated links. The apparatus includes a straight guide portion (16) having a length at least equal to the length of each arm segment so that the arm control system can be calibrated as each segment passes through the guide.
摘要:
A robotic arm of the "top following" type, which can advance into an environment is covered is covered by a sensorised skin. The arm can thus detect a parameter of the environment, and the shape can be adjusted accordingly.
摘要:
A computer implemented method for servicing an engine including receiving information including an initial condition profile, CP1, of the engine; forming a workscope associated with a servicing operation of the engine in view of the initial condition profile, CP1; servicing the engine in view of the workscope; determining at least in part an updated condition profile, CP2, of the engine in view of information acquired during the service; and storing the updated condition profile, CP2, for use in a subsequent service operation.

A pulse illumination imaging system is provided. The system includes an image sensor (112), a light source (110), and a controller (116). The image sensor (112) includes a plurality of light sensitive pixel elements (200) that are activatable, for a designated exposure time (300) to capture one or more images. The controller (116) is configured to determine an activation time to activate the image sensor (112) based on motion of a target element (120) relative to the image sensor (112); activate the image sensor (112) at the activation time; and activate the light source (110) during the exposure time (300) of the image sensor (112) to produce a pulse having a preconfigured time duration that is less than the exposure time (300) of the image sensor (112).
摘要:
An inspection system (20) and related methods that employ directional light for enhanced imaging are provided. The inspection system (20) includes an inspection camera (24) and at least one directional light source (26) positionable in an offset position from a field of view (46) of the inspection camera (24). The at least one directional light source (26) is configured to emit directional light from the offset position into the field of view (46) of the inspection camera (24) so as to produce shadows on a surface of interest (48). Further, the inspection system (20) includes a display device (34) coupled to the inspection camera 24) and the inspection camera (24) is configured to capture one or more images of the shadows produced on the surface of interest (48). The display device (34) is configured to receive and display the one or more images.
摘要:
An insertion tool for performing an operation on equipment, the insertion tool including: a plurality of segments, each segment of the plurality of segments including a body including: a first hinge; a second hinge, the first and second hinge members pivotally coupling adjacent segments of the plurality of segments together; and a cavity extending along the body of the segment, the cavity exiting the body at a plurality of exit locations, wherein at least one of the plurality of exit locations is disposed adjacent to the first hinge; and a selectively rigidizable strength member disposed within the cavity.
摘要:
A tool system (100) for inserting into a cavity, the tool system including a first continuum (102) having a flexible body defining a connection interface; and a second continuum (104) having a flexible body defining a connection interface (106); and an engagement mechanism (118) configured to couple the connection interfaces (106) of the first (102) and second (104) continua together to form the tool (100).
摘要:
An inspection system (100) and related methods are provided. The inspection system (100) includes an inspection camera (102), a plurality of light sources (112D) (112C) (112B) (112A) (112) collocated with the inspection camera (102), and a post processing system (108). The plurality of light sources (112D) (112C) (112B) (112A) (112) output directional light that have different respective ranges of light wavelengths. The inspection camera (102) is configured to capture image data while a surface of interest (120B) (120A) (120) is being illuminated with the directional light. Further, the post processing system (108) is configured to receive the image data, process portions of the image data into a plurality of images that include distinct images corresponding to the different respective ranges of light wavelengths. The plurality of images can be reviewed to identify an abnormal region of the surface of interest (120B) (120A) (120).
