Abstract: Apparatus, methods, and systems for wrapping a soiled diaper and/or other odorous items in a sheet material are disclosed. In one embodiment, a soiled diaper is placed on a sheet of material. The material may be configured to be adhered to itself without a secondary means for adhesion so as to create a seal around at least a portion of the diaper. The material may also include an adhesive side and a non-adhesive side, and the adhesive side may comprise a pressure-sensitive adhesive. In this manner, unintentional adhesion of the material can be avoided, and the material can be folded over the soiled diaper and pressed against itself to seal in the odor and/or mess without requiring a secondary means for adhesion, such as tape.

Abstract: A method for teaching a practical skill to a plurality of learners at geographically separate locations includes receiving, for each learner, a video feed generated by a camera at the learner's location. The video feed depicts at least an subject on which the learner is demonstrating the practical skill. The teacher simultaneously displays the video feeds for the plurality of learners on a display screen at a location of the teacher. One or more learners are allowed to submit questions to the teacher that are not immediately conveyed to the other learners. The teacher is allowed to select one of the learners having a question for individualized instruction, and to establish a private communication channel between the teacher and the selected learner.
