An imaging system having a forward and rearward orientation and comprising: (a) one or more parabolic reflectors having a base, a focus, and a reflector axis, said one or more parabolic reflectors defining a central reflector axis; (b) at least one a light source disposed near or essentially at said focus of each of said one or more parabolic reflectors forward of its base; and (c) an imaging device disposed within said one or more parabolic reflectors, and comprising a zooming lens having an optical axis essentially coincident with said central reflector axis.

Imaging device with focused illumination

An inspection system comprising (a) one or more sleds, each sled comprising (i) three or more rails running lengthwise and defining a diameter and a central axis of said each sled, (ii) first and second mounts, (iii) a nozzle comprising an interface configured for connection to a hose, and (iv) one or more jets configured for communicating fluid from said hose outward; (c) a camera module comprising (i) a housing, (ii) a camera having an optical axis, (iii) one or more lights; (iv) at least one battery, (v) memory operatively connected to said camera for recording images from said camera; and (vi) front and rear members for interengaging with said first and second mounts, respectively, such that at least one of said front or rear members urges against said first or second mounts to secure said camera module to said each sled such that said optical axis is essentially coincident with said central axis.

Nozzle mounted camera

A push camera apparatus comprising: (a) at least one reel configured to rotate on a base to pay out or reel in a cable, the reel having a cable input; (b) the cable having a proximate end and a distal end, the proximate end being connected to the cable input; (c) a camera connected to the distal end and configured to transmit image data through the cable to the cable input; and (d) a communication module operatively connected to the cable input and configured to rotate with the reel, and to transmit wirelessly the image data from the cable input to a wireless controller.

Imagining device with focused illumination

An imaging system comprising a parabolic reflector having a base and defining a first axis, a light source disposed proximate the base essentially along the first axis, an imaging device comprising a zooming lens having a second axis, the imaging device being disposed in front of the light source along the first axis such that the second axis and the first axis are essentially coincident.

The present invention relates to methods and apparatus utilizing distributed temperature sensing (DTS) to monitor the temperature of a cured-in-place pipe liner to determine if proper curing temperatures and times are achieved. More particularly, an optical fiber is placed between the pipe and the liner running the entire length of the liner. The optical fiber is coupled to a DTS unit. During curing of the liner, the DTS unit sends light pulses down the fiber from one end and detects the characteristics and time delay of light backscattered to the unit. The characteristics are indicative of the temperature of the optical fiber, while the delay is indicative of the round trip time of the light within the fiber, and thus the distance from the DTS unit from which any particular backscatter signal originated.

Method and apparatus for determining proper curing of pipe liners using distributed temperature sensing

A method of inspecting a lateral pipe extending from a manhole, said method comprising: (a) inserting an imaging head into said manhole using a positioning system, said imaging head connected to an elongated member and comprising an imaging device adapted to convert an image to an image signal, a lens optically coupled to said imaging device, and at least one lamp suitable for projecting a light beam, said lamp having a beam that is adjustable to enable said beam to move relative said imaging device; (b) imaging a target located within said lateral pipe; (c) holding said imaging device essentially steady while imaging said target and adjusting said beam to adjust the illumination of said target.

Inspection system and method

A method of inspecting a lateral pipe extending from a manhole, the method comprising: (a) extending an imaging head into the manhole using a positioning system, the imaging head comprising an imaging device and at least one lamp capable of producing a light beam, the positioning system comprising an elongated member and a targeting fixture operatively connected thereto, the imaging head being attached to one end of the elongated member, the targeting fixture having a distal end biased outwardly from the imaging head; (b) placing the distal end on a rigid surface proximate to the lateral pipe; (c) pushing down on the elongated member such that the distal end resiliently moves toward the imaging head, thereby allowing the light beam to be centered approximately in the lateral pipe; and (d) imaging a target located within the lateral pipe.
