Abstract: A method comprises: directing a laser beam onto a side of a tube, wherein the side includes a defect; moving the tube with respect to the laser beam such that the laser beam beams onto the defect; sensing a reflection of the laser beam from the side based on the defect; computationally identifying a change between the laser beam and the reflection; computationally acting based on the change. The side can be internal or external. In other implementations, the laser beam is moved with respect to the tube such that the laser beam beams onto the defect.

Abstract: An example transition fitting includes a fitting body have a first shoulder, a second shoulder and a compression region extending radially inwardly from the first shoulder and the second shoulder. A fluid conduit is attached to the fitting body about the compression region. The fluid conduit is deformed radially inwardly from the first shoulder and the second shoulder to secure the fitting body in an axial direction along a longitudinal centerline axis of the fitting body. The fitting body is rotatable along a longitudinal centerline axis of the fitting body.

Abstract: Transmitting caller identification data to residential equipment within a digital transport stream is provided. Telephony signals that include caller identification data are received and the caller identification data is extracted from the telephony signals. The caller identification data in is then embedded the digital transport stream. The digital transport stream, including the caller identification data, is transmitted to residential equipment. The residential equipment extracts the data from the digital stream and presents the caller ID data to a subscriber overlaid on video.

Abstract: The present invention provides a system and method for using existing wiring or cabling in a residence or other customer premises both (a) to transmit network telecommunications to a gateway or similar device for processing, and (b) to distribute processed signals from the device to video, telephony and data receivers. The invention enables and facilitates the receipt by telephone company subscribers of high-speed digital telecommunications over twisted-wire pair cabling historically installed and used for voice telephone service. In an embodiment, the system of the present invention comprises a bidirectional transmission facility, a first diplexer, and a second diplexer; the first diplexer receives network signals and transmits them or passes them on, using the bidirectional transmission facility, to the second diplexer; and the second diplexer receives distribution signals and transmits them or passes them on, using the bidirectional transmission medium, to the first diplexer.

Abstract: A DC electrical power supply system for converting AC power to DC power for various telecommunications equipment loads includes plural rectifiers mounted on one or more shelves and adapted to be inserted on and removed from said shelves, at will. One or more voltage converters may be inserted and removed from said shelves at will and include adapter plates for supporting the converters in place of a rectifier unit. The power supply system includes a frame supporting the shelves and a cabinet which includes busworks for connecting the rectifiers to circuit breaker tiers and to a battery pack. Low voltage disconnect devices may be interposed in the buswork at selected locations to provide operation in a battery protection mode, load protection mode and load shedding mode. The circuit breaker tiers, buswork, shelving, rectifier units and converters are all accessible for connection and disconnection from the front side of the power supply system.
