Abstract: One or more systems, methods, routines and/or techniques for automated frame of reference calibration for augmented reality are described. One or more systems, methods, routines and/or techniques may allow for calibration of an Augmented Reality (AR) system, for example, by automatically calibrating the frames of reference of virtual objects and/or a camera. One example calibration routine and/or technique may determine and/or calculate a mapping or transform from a frame of reference of a virtual object (e.g., a CAD model) to a coordinate frame associated with the tracking system. Another example calibration routine and/or technique may determine and/or calculate a mapping or transform from a camera lens frame of reference to a frame of reference of the whole camera as determined by a tracking system. These routines and/or techniques may calibrate an AR system to provide rapid, precise alignment between virtual content and a live camera view of a real scene.

Abstract: A core-in-shell heat exchanger, a method of fabricating the core-in-shell heat exchanger, and a method of exchanging heat in a core-in-shell heat exchanger disposed on a slosh-inducing moving platform are described. The method of exchanging heat includes introducing a shell-side fluid into a shell of the core-in-shell heat exchanger and introducing a fluid to be cooled into each of one or more cores of the core-in-shell heat exchanger, the one or more cores being arranged along an axial length of the shell with a plurality of baffles disposed on either side of the one or more cores along the axial length of the shell to reduce slosh of the shell-side fluid. The method also includes draining excess shell-side fluid using a plurality of drains, at least two of the plurality of drains being disposed on opposite sides of one of the plurality of baffles.

Abstract: A heat exchanger system includes a core-in-shell heat exchanger and a liquid/gas separator. The liquid/gas separator is configured to receive a liquid/gas mixture and to separate the gas from the liquid.

Abstract: An embodiment of a method for supplying refrigerants to a liquefied natural gas (LNG) facility includes: advancing a first refrigerant from a first storage device to a heat exchanger, the first refrigerant having a first temperature; advancing a second refrigerant from a second storage device to the heat exchanger, the second refrigerant having a second temperature different than the first temperature; flowing the first refrigerant and the second refrigerant through the heat exchanger; adjusting the second temperature based on at least a transfer of heat between the first refrigerant and the second refrigerant in the heat exchanger; and transferring the first refrigerant and the second refrigerant to the LNG facility.

Abstract: A conduit seal assembly includes an outer conduit having a first end with a first opening and a second end, opposite the first end, with a second opening. A first seal is positioned in the first opening for resisting a first temperature, and a second seal is positioned in the second opening for resisting a second temperature less than the first temperature. The first and second seals define a cavity and provide an air-tight seal of the cavity, and the assembly includes a monitoring assembly configured to sense a characteristic in the cavity.

Abstract: Methods and systems for inspecting a workpiece are provided. The method includes storing model data associated with the workpiece in an inspection system, determining a relative position of a depth sensing device relative to the workpiece, and calibrating a pose view for the inspection system relative to the model based on the position of the depth sensing device relative to the workpiece. The method further includes measuring actual depth distance data of at least one pixel of the depth sensing device relative to the workpiece and determining, based on the actual depth distance data, if the workpiece satisfies predetermined inspection criteria.

Abstract: In representative embodiments, a system includes an acoustic emitter, a controller, an optical sensor, and an indicator for indicating a detection of a predetermined trace chemical vapor by the optical sensor. The acoustic emitter is positioned at a predetermined distance above the ground surface and configured to project a beam of acoustic energy toward the ground surface with a variable angle of incidence ?. The controller is configured to control the acoustic emitter to vary the angle of incidence of the acoustic beam within the variable angle of incidence ?, while the optical sensor is configured for standoff sensing of a trace chemical vapor proximate the ground surface. Excitation of the ground surface, particularly at a critical angle of incidence ?, causes the release of trace chemical vapors from a buried source and the soil into the air above the buried source.

Abstract: A system to provide remote support may include a video camera to acquire a video image of a chosen scene and a field augmenting device to present the video image. The system may also include a module associated with the field augmenting device to permit augmentation of the video image by field personnel, wherein augmentation comprises at least one of selection of a feature in the video image and association of any attributes to the selected feature. A support site augmenting device may be provided to receive a video transmission including the video image and any augmentation by the field personnel over a network from the field augmenting device and to present the video image including any augmentation to support personnel.
