Statement Appendix

2/10/1518

Mini Air is a lightweight, rechargeable necklace that will keep an individual cool during the hottest days and warm during the coldest. This small, comfortable device will send air from a person’s chest to a person’s neck and keep them 15°F warmer or cooler than the surrounding ambient temperature depending on the wearer’s needs. Conventional heating and cooling devices such as air conditioners and heaters are bulky, non-portable and are capable of one function - Mini Air hopes to change this.

The aim of this project is to analyze existing devices to create a smaller, easy to use, energy efficient and cost effective product that will keep the user at a comfortable temperature. The final result will be a useful prototype that can be manufactured and would be consistent with the customer’s provisional patent and meet necessary federal safety requirements in order to have a successful transition into the marketplace.
