A method and apparatus for recognizing a state machine in circuit design in a high-level IC description language. In an alternative embodiment, rather than resting, the ion exchange resin is periodically conditioned with an acid so as to enhance the secondary mechanism. In the registration phase, an authenticating authority registers the user based upon identification of the user using a strong authentication technique and provides an authenticating token to the user, which can be used in the enrollment phase to enroll one or more user devices for the user. The connector may be used in a holding application, a latching application, or both a holding with latching application. Air vents are formed through the covering wall and provide communication between the bag-shaped space and an outer surface of the covering wall.
