Abstract: A multi-layered face mask coated with discontinuous patterns of phase change material are incorporated into the face mask construction to provide for cooling of the microclimate in the dead space of the face mask. Optimized cooling is achieved by strategic placement of layers coated with a phase change material within the mask construction and the amount and density of the phase change material in contact with the temperature sensitive areas of the face, as well as areas experiencing the maximum amount of flux from exhaled breath. The shape of the mask can also be adjusted to increase skin contact with the phase change material and decrease dead space volume, which reduces the volume of warm exhaled air and can provide sufficient cooling with less phase change material. The discontinuous patterns of phase change material also provide inter-layer spacing between the layers of the mask, which can improve splash resistance.

Abstract: The present invention embraces a method and apparatus for providing feedback to a user on the status of media or ribbon of a printer. The feedback may be provided by incorporating a feedback mechanism in a hanger of a printer. The printer may be a thermal printer, but may be another type of printer. The feedback mechanism of the printer may be designed to work with one or more sensors to provide a feedback loop so that without an input from a user, the printer is able to detect the presence/absence of media or ribbon, as well as determine the width of the loaded media or ribbon. In another embodiment, the feedback mechanism is able to determine the weight of the roll of media or ribbon and hence determine the quantity of media or ribbon available on the hanger.
