Abstract: A method of operating a video camera includes capturing a scene of imaging data using a focal plane array (FPA) module of the video camera. The scene of imaging data is characterized by a first bit depth. The method also includes processing, using an image processing module coupled to the FPA module, the scene of imaging data to provide display data characterized by a second bit depth less than the first bit depth. The method further includes forming a super frame including the display data and the scene of imaging data and outputting the super frame.

Abstract: Some embodiments of the present light fixtures include a body, a waveguide, and one or more independently-controllable light sources. The waveguide is configured to be coupled to the body and may include a first end configured to receive light emitted from at least one of the light source(s) and to direct the received light to (and in some embodiments, emit the received light from) a second end of the waveguide. In some embodiments of the present fixtures, the waveguide defines an opening through which light emitted from at least one of the light source(s) can pass, the light source(s) being coupled to the body such that a first one of the light source(s) emits light into the first end of the waveguide and a second one of the light source emits light through the opening.

Abstract: Some fixture mounts include a body that is couplable to a structure, the body having an upper surface, a lower surface, and a peripheral surface that connects the upper and lower surfaces and defines one or more ledges, wherein the body is couplable to a fixture such that each of first and second protruding features of the fixture is received between one of the ledge(s) and the upper surface. In some fixture mounts, the protruding features are slidable along the ledge(s) above which they are received such that the fixture is rotatable relative to the body. In some fixture mounts, at least one of the ledge(s) is tapered such that, as a protruding feature of the fixture that is received above the ledge is moved toward the ledge, the fixture is urged toward the upper surface.

Abstract: A method for testing an insert packer assembly positioned within a diverter assembly includes inserting a test tool through an opening of the insert packer assembly and into a bore of the diverter assembly. The method includes driving multiple annular flexible components of the insert packer assembly radially inward to contact an outer annular surface of the test tool to form a sealed space between the multiple annular flexible components and the outer annular surface of the test tool. The method also includes applying a fluid to the sealed space to increase a pressure within the sealed space and monitoring the pressure within the sealed space over a period of time to determine a condition of the insert packer assembly.

Abstract: A method for control of the air/fuel ratio of the burner(s) (excess air) of a thermal cracker includes three steps. The thermal cracker has three consecutive zones or portions through which combustion gases pass, a firebox portion, a bridge wall portion and a convection portion The first step is to direct a wavelength modulated beam of near infrared light from two different tunable diode lasers located in the bridge wall portion through combustion gas from the burner to a pair of near infrared light detectors, each positioned to receive the wavelength modulated beam of near infrared light from a different one of the two tunable diode lasers to generate a detector signal. The second step is to analyze the detector signals for spectroscopic absorption at wavelengths characteristic of oxygen and carbon monoxide to determine their respective concentrations in the combustion gas.
