Abstract: According to one aspect, a three-dimensional model of at least a portion of a wellsite is generated. A three-dimensional camera system is calibrated to the three-dimensional model. A draw-works encoder is calibrated. The motion of a component is monitored. The draw-works encoder is recalibrated based on the monitoring. According to another aspect, three-dimensional imaging data sets are received, the three-dimensional imaging data sets being associated with a control volume in which the portion of the wellsite is disposed. A predefined three-dimensional model is augmented with the three-dimensional imaging data sets. According to another aspect, at least one three-dimensional camera employs a first three-dimensional sensing technology that is different from a second three-dimensional sensing technology employed by at least one other three-dimensional camera. A single three-dimensional model is generated by merging respective three-dimensional imaging data sets.

Abstract: A diffuser seal for an aft end of a high pressure compressor of a gas turbine engine is disclosed. The diffuser seal includes a flow guide carrier coupled to the diffuser case. The flow guide carrier is also coupled to a static seal. The static seal engages a rotary seal and permits air flow through the static and rotary seals in the aft direction. The flow guide carrier is also coupled to a fairing and a fairing/hub support. The flow guide carrier supports the fairing in a spaced-apart position with respect to the rear hub so that air flowing through the static and rotary seals passes between a forward surface of the fairing and the rear hub. The fairing/hub support extends forward from the flow guide support and engages an aft surface of the fairing thereby limiting movement of the rear hub and fairing in the aft direction. This design helps to prevent parts or debris from piercing the rear hub and entering the high pressure turbine in the even of a fan blade-out or fan blade-off event.
