Abstract: Pairing a digital media file with a digital autograph can be achieved with systems and methods that verifying an identity of the user. A digital media file including at least one image and a digital autograph including text are each selected. The selected digital media file and the selected digital autograph are combined into a combined media file that is certified by the user. Output of the combined media file can therefore provide an authenticated and autographed media product.

Abstract: A container is described for holding and dispensing chilled fluids for consumption by a user. The container may include a temperature indicating device configured to indicate whether a current temperature of liquid is at or below a first temperature value. The container may include a plurality of gradations configured to indicate a plurality of liquid levels in the enclosed chamber. Each pair of the plurality of liquid level gradations may have a corresponding volume. A plurality of caloric indicia may be displayed in conjunction with the plurality of gradations. Each caloric indicia may display a caloric energy value corresponding to heating one or more of the volumes of aqueous liquid from the first temperature value to a second temperature value. The container may be included in a kit with instructions directing a user in operation of the container, for example, as part of a diet or regimen of physical fitness.
