Abstract
Methods and systems are presented for configuring oxygen barriers for controlled access to chemical warming agents such as wood fiber, vermiculite, activated charcoal, iron, and salt. In this way a smart phone, syringe, or other cold-sensitive device may be warmed by such agents to restore or maintain functionality in a frigid environment.
