Abstract: A system and method for indoor spatial mapping. The system includes a mobile mapping device having a camera; a plan database configured to store 2-D floor plans; and a processor configured to integrate a selected floor plan from the plan database with object data received from the mobile mapping device to create an interactable 3-D spatial mapping of an interior portion of a structure so that one or more objects are moveable relative to a surrounding environment within the 3-D spatial mapping. The processor is configured to recognise objects from an image from the camera and anchor the recognised object within the interactable 3-D spatial mapping.

Abstract: A leading edge of a wind-turbine blade has a carefully designed predetermined shape. After operation of the blade, erosion damages that shape and the blade needs repair. Repair is difficult to carry out in the field or, for offshore turbines, at sea. A shroud (8) for repairing a damaged leading edge of a wind-turbine blade (2) is rigid and has a shape matching the predetermined shape of the leading edge. Advantageously the shroud has a multi-layered structure in which a base layer (10) of the shroud comprises a rigid material.

Abstract: Repairs need to be carried out on various structures in outdoor climatic conditions, which may be in wind or rain. Such a structure may be a wind turbine blade (1). This limits the time when the repairs can be conducted while conditions are within the limits set for the process. The invention provides an enclosure (4) which can be sealed to the structure so that a repair can be conducted at any desired time. The enclosure is large enough to enclose a desired work area with the operator's hands and arms entering to carry out the work through hand and arm seals (6, 7).

Abstract: A low emission turbine includes a reverse flow can-type combustor that generally includes a primary and secondary fuel delivery system that can be independently controlled to produce low CO, UHC, and NOx emissions at design set point and at conditions other than design set point. The reverse flow can-type combustor generally includes an annularly arranged array of swirler and mixer assemblies within the combustor, wherein each swirler and mixer in the array includes a primary and secondary fuel delivery system that can be independently controlled. Also disclosed herein is a can-type combustor that includes fluid passageways that perpendicularly impinge the backside of a heat shield. Processes for operating the can-type combustors are also disclosed.

Abstract: A gas cooking system having a gas cooking burner that includes a gas line, a first gas port coupled to the gas line, and a second gas port disposed downstream from the first gas port, wherein at least one of the first and second gas ports comprises a non-circular geometry adapted to increase air entrainment, the second gas port further being non-rectangular if the first gas port has a circular geometry.

Abstract: A fuel nozzle device suitable for use in a gas turbine engine or the like is provided. The fuel nozzle device includes a fuel line and a plurality of gas orifices disposed at a downstream end of the fuel line, the plurality of gas orifices operable for injecting fuel into an air stream. The acoustic resistance of each of the plurality of gas orifices is chosen to match the acoustic impedance of the fuel line such that the maximum acoustic energy may be transferred between the fuel nozzle device and the combustor, thus enhancing the ability of the fuel nozzle device to control the combustion dynamics of the gas turbine engine system. A fuel injection resonator assembly suitable for use in a gas turbine engine or the like is also provided. The fuel injection resonator assembly includes a plurality of orifices separated by a variable length tube.
