Abstract: An authentication system identifies patterns of access request to a network to limit access to the network by malicious devices. Upon receiving an access request, the authentication system attempts to insert a first feature of an access request in a first table. If an error occurs, the authentication system attempts to insert two or more features of the access request into a second table. If the insertion does not cause an error, the authentication system queries the second table using the first feature. Upon detecting that the number of entries of the second table associated with the first feature is great than a threshold, the authentication system terminates access to network by devices associated with the first feature.

Abstract: Oral devices are provided, including oral brushes that include bristle tufts and a rotatable member having radially extending protrusions constructed to wedge between a user's teeth and, among other things, cause compression of the papilla.

Abstract: An oral device is provided that includes a handle, a head, extending from the handle and having a pair of elongated arms that include opposed surfaces; and a pair of opposed cleaning elements, mounted on the opposed surfaces, the cleaning elements being constructed and positioned to be inserting into the interproximal regions of a user's mouth when the oral is moved back and forth over the user's teeth. Each of the cleaning elements are positioned at an acute angle with respect to an interproximal line defined through the interproximal region.

Abstract: A medical fastening system for a modular knee prosthesis system includes a femoral component having a first surface, a second surface, and an aperture extending therebetween. A modular adapter element has a first end that is mountable adjacent the first surface of the femoral component and a second, mating end that is engagable with a second prosthesis component. The system also includes a first bolt that mates the adapter element to the femoral component. Various connection options are possible to secure different components of the system to each other.
