Abstract: Enclosures and panels for forming such enclosures can include a first edge having a front side and a rear side, each side having a first portion of a fastening medium thereon, and a second edge having first and second flaps, each flap having an inner surface with a second portion of the fastening medium thereon. The flaps of a first panel can engaged with the front and rear sides of an adjacent panel, and similarly, any number of adjacent panels can be engaged in this manner to form a sealed enclosure, usable for maintaining a pressure differential between the interior and exterior thereof.

Abstract: A biometrically authenticated access control in which a wireless authentication signal is provided from a primary instrumentality of access, only after a dual-stage biometric verification of the user's identity is performed. In one embodiment, an accessing device includes memory for storing a device identification code and an authentication code, along with first and second biometric templates corresponding to biometric samples from a user. In another embodiment, an accessing device includes memory for storing a device identification code and more than one authentication code, for separate users, along with first and second biometric templates corresponding to biometric samples from multiple users. In order to gain access to a secured resource, a user undergoes first and second biometric sampling to generate biometric data to be compared with the first and second biometric templates.
