  • Attachment block for blade outer air seal providing impingement cooling
    Patent number: 10961866
    Abstract: A gas turbine engine includes a compressor section and a turbine section. The turbine section includes at least one turbine rotor having a radially extending turbine blade. The turbine section is rotatable about an axis of rotation. A blade outer air seal is positioned radially outwardly of a radially outer tip of the at least one turbine blade. The blade outer air seal has axially spaced forward and aft portions and a central web between the axially spaced portions. An attachment block is supported on structure within the engine. The attachment block mounts the blade outer air seal. A passage extends into a central chamber within the attachment block, and communicates with cooling holes through a radially inner face of the attachment block to direct cooling air at the central web of the blade outer air seal. A blade outer air seal is also disclosed.

  • Photographic lighting system and method
    Patent number: 10962861
    Abstract: Photographic lighting devices, systems, and methods having a plurality of electrical energy storage/discharge (EESD) elements and/or one or more light sources in a single photographic lighting device to perform one or more photographic lighting effects. EESD elements and one or more light sources can be configured to have multiple separate light emissions occur in a single image acquisition window. The multiple light emissions are separated in an image acquisition window by a time period that is about shutter speed exposure time/(N?1), where N is the number of light emissions. In one such example, two light emissions are separated by a time period that is about shutter speed exposure time/(N?1).
