Abstract: Systems and methods of controlling outputs of infrared heaters used to join a first part to a second part, and a component made thereby. Upper and lower nests hold the first and second parts, respectively. A movable heating platen has infrared heaters on opposite surfaces. Imaging sensors have fields of view encompassing heated portions of the first and second parts, respectively, when the platen is retracted away from an area between the upper and lower nests. A controller causes the upper and lower nests to move while causing the platen to extend into and retract away from the area between the upper and lower nests. The first imaging sensor takes a first image of the heated portions of the first part, which causes an adjustment to be made to an output of the infrared heaters in a subsequent welding cycle.

Abstract: A method is disclosed as including sending, to a remote server, information identifying a first location within a building. In response to such sending, data may be received from the remote server. The data may comprise a plurality of unique identifiers, each unique identifier thereof corresponding to a unique radio tag located in a unique location within the building. The data may be used to deliver to a user a first series of audible commands guiding the user within the building toward the first location. For example, a first radio transmission may be received from a first radio tag located within the building. The first radio transmission may communicate a first identifier that is associated within the data to first navigation information. Thus, the first navigation information may be used to guide the user within the building toward the first location.

Abstract: A self driven pig may have a drive using slanted wheels on an element rotated axially relative to a reference element to drive the pig along a pipe, and may have a sensor carrier with a housing holding the sensors which rotates axially to provide better sensor coverage of the walls of the pipe.

Abstract: A method for repairing a damaged area of a bitutinous wearing course. The method comprises heating the damaged area, applying a liquid to the damaged area that rejuvenates damaged bitumen, adding new material to the damaged area in an amount required to level the area, and compacting the new material. The invention also provides a new composition for rejuvenating damaged bitumen. The composition may comprise an emulsifier, a heavy paraffinic distillate solvent extract, a heavy naphthenic distillate solvent extract and water.
