A method includes engaging in authentication operations each involving apparent use of a legitimate authenticator. Values of one or more authenticator variables are received and stored, where the authenticator variable(s) normally change in a known authenticator-specific way during the authentication operations, such as being calculated from a monotonically increasing dynamic variable. A risk analysis function is applied to the stored values to generate a risk indicator signal indicating a level of risk that the clone authenticator is in use. The risk analysis function includes detection of an abnormal change of the authenticator variable(s), such as use of non-monotonic dynamic variable values. The risk indicator signal is output to an access controller that operates, based on the level of risk indicated by the risk indicator signal, to selectively inhibit an otherwise successful authentication operation involving apparent use of the legitimate authenticator.

The invention includes methods and apparatus for correcting shading non-uniformity in camera systems. A method includes capturing at least two sets of flatfield images from at least two sets of camera modules under first and second illuminant, respectively. Pixels for each image in the sets of flatfield images are then averaged to form first and second averaged flatfield images, respectively. The first averaged flatfield image is transformed using the second averaged flatfield image to create a transform image. The transform image is then saved in memory for calibrating the shading non-uniformity of the camera module.

A method for forming a cabling media includes providing a wire pair including first and second conductor members. Each of the first and second conductor members includes a respective conductor and a respective insulation cover surrounding the conductor thereof. The first and second conductor members are twisted about one another to form a twisted wire pair having a twist length that purposefully varies along a length of the twisted wire pair. The method may include: imparting a purposefully varied pretwist to the wire pair using a wire pair twist modulator; and imparting additional twist to the wire pair using a wire pair twisting device downstream of the wire pair twist modulator.

A modular stand-alone shelving system comprising left and right vertical support members, each having front and rear corner posts connected by a welded grid of horizontal and vertical rods. A plurality of shelves formed of sheet metal are disposed between the vertical support members, each shelf including hook elements formed near the corners thereof for engaging and resting on horizontal rods of the grid. A back member extends between the vertical support members and also includes hook elements formed near the corners thereof for engaging and resting on horizontal rods in the grid. Upper corners of the back member include first and second hooks disposed in planes spaced apart by the thickness of the vertical rods. When installed, the hooks rest on horizontal rods and straddle a vertical rod, preventing motion of the back member and rhombic distortion. The back member prevents rhombic distortion in the X and Z directions.
