The present invention includes an umbrella anti-inversion apparatus comprising a removable cuff and a plurality of removable and adjustable straps. A motor has a longitudinal bore, a friction area within the longitudinal bore, and a guide wire disposed within the longitudinal bore. After receiving data of a certificate from an information browser, verifying the certificate and imposing a limit on access based upon one of access control conditions, the storage device transmits data of the license and the other to the information browser. A thermal oxidation is performed to convert semiconductor materials underneath sidewalls of the first trench into an upper thermal oxide portion and a lower thermal oxide portion, while the remaining oxygen-impermeable layer on sidewalls of a second trench prevents oxidation of the semiconductor materials.
