Abstract: Methods and apparatuses are described for automatic classification of error conditions in automated user interface testing. A server receives an image file corresponding to a current user interface (UI) view of a software application under test. The server analyzes the image file to identify error conditions that exist in the current UI view. The server assigns a classification to the image file according to one or more error types based upon the error conditions identified in the current UI view. The server transmits a notification message to one or more remote computing devices, the notification message comprising the image file and the classification assigned to the image file.

Abstract: An antenna assembly is for a fuselage of an aircraft and includes a first satellite antenna operable in a first frequency range, a second satellite antenna operable in a second frequency range, and a radome covering the first and second satellite antennas. The radome includes, in stacked relation, an inner skin having a quartz fabric and epoxy resin, an inner core having epoxy syntactic foam, a center laminate having quartz fabric and epoxy resin, an outer core having epoxy syntactic foam, and an outer skin having quartz fabric and epoxy resin. A fairing mounts the radome to the fuselage of the aircraft.

Abstract: A torque tube assembly for transmitting rotational force from a first end to a second end includes a number n of concentric elongate torque tubes, where n is an odd integer greater than or equal to three. The concentric elongate torque tubes are connected for co-rotation. A serpentine thermal conduction path is defined between the first end of the torque tube assembly and the second end of the torque tube assembly, and includes at least a portion of each of the concentric elongate torque tubes.

Abstract: A unitary bimetallic shield ring for a superconducting generator rotor includes coaxial inner and outer cylindrical portions. The outer cylindrical portion comprises a first metallic material for conducting eddy currents to dissipate energy, and defines an interior face. The inner cylindrical portion comprises a second metallic material for providing structural support to the outer cylindrical portion. The inner cylindrical portion is continuously metallurgically joined with the interior face of the outer cylindrical portion. The shield is made by first forming a substantially continuous weld between the inner and outer layers, and then machining the shield.

Abstract: A shaftless rotor (12) for a dynamoelectric machine includes a stack (20) of ferrous laminations (22) provided with a central opening (110) extending through the stack (20) and adapted to be located on the axis of rotation (14) of the rotor (12). A sleeve (112) is located in the central opening (110) for orienting the laminations (22) with respect to one another. Manifold and vane clamping pieces (52) are located on opposite sides of the stack (20) and engage the endmost laminations (22) and the sleeve (112). A pair of spaced shaft segments (24,26) engage respective ones of the clamping pieces (52) and a single tie bolt (32) extends through the sleeve (112) between the shaft segments (24,26) to interconnect the same. The tie bolt is in tension to apply clamping force to the shaft segments (24,26) for transmittal to the clamp pieces (52) to the laminations (22) in the stack (20).

Abstract: The hydraulic components of a cooling circuit for a dynamoelectric machine are eliminated in a totally air cooled dynamoelectric machine which includes a rotor (12) rotatable about an axis (14) and including a central stack (20) of ferrous laminations (22) defining a plurality of radially outwardly directed circumferentially spaced poles (132), spaced shaft ends (24,26) on the axis (14) and extending from opposite sides of the stack (20) and a first air passage (46) in the stack (20). Magnetic journal bearings (54,56) and a magnetic thrust bearing (58,60) are provided for the shaft segments (24,26) and impellers (62) are located on opposite sides of the stack (20). A stator (16) surrounds the rotor (12) and includes windings (76) connected by end turns (94) located exteriorally of the stator (16).

Abstract: A magnetic bearing system (24) supports a shaft (20). The bearing system (24) includes a magnetic rotor (34) and a stator element (36) positioned in proximity to the rotor (34). A plurality of first electromagnets (40, 41, 42) are mounted in the stator element (36). The first electromagnets (40, 41, 42) are of relatively large size to provide high load bearing capacity. A plurality of second electromagnets (44, 45, 46) are mounted in the shator element (36) in spaced relation with the first electromagnets (40, 41, 42), the second electromagnets (44, 45, 46) being of relatively small size to provide high frequency response. Displacement sensors (56, 57, 58) sense position of the shaft (20) relative to the stator element (36). A controller (60) is coupled to the displacement sensors (56, 57, 58) and the electromagnets (40, 41, 42, 44, 45, 46) for controlling current thereto.
