Abstract: Methods, apparatus, systems, and articles of manufacture are disclosed. An example system includes: interface circuitry; programmable circuitry; and instructions to program the programmable circuitry to: obtain audio of a media presentation; obtain ambient noise in an area associated with the media presentation; determine an intensity of a difference between the audio and the ambient noise; and determine an engagement level of an audience of the media presentation based on a duration the intensity satisfies a threshold value.

Abstract: A multi-component dispensing package and method for forming and using same. The package stores reactive viscous materials separately for expressing from the package in desired proportional quantities. The components are contained in adjacent parallel tubes of thin, non-resilient deformable material such as aluminum foil which may be protected by a paper cover. In use, one sealed end of the tubes is snipped or severed from the package, and a member is pressed against the package and moved toward the open ends to extrude desired quantities of the components in desired volumetric ratio. This flattens the end of the tube which is then used to mix the extruded components. During the mixing a layer or bead of the mixture coats the flattened end for hermetically sealing the components from each other and from the atmosphere.
