The ability of an ultrasonic system to sweep and lock onto a resonance frequency of a blade subjected to a heavy load at startup is improved by applying a high drive voltage or a high drive current while systematically increasing the level of the applied signal. Increasing the drive signal to the hand piece results in an improved and more pronounced “impedance spectrum.” That is, under load, the increased drive signal causes the maximum phase margin to become higher and the minimum/maximum impedance magnitude to become more pronounced. Increasing the excitation drive signal to the hand piece/blade at startup significantly alleviates the limiting factors associated with ultrasonic generators, which results in an increase of the maximum load capability at startup.

An arrangement of building elements capable of a snap-fastening interconnection comprises an element, especially the tongue, consisting of a different material from the other building elements. An MDF/HDF panel, is initially milled along the longitudinal and/or transverse sides, and the resulting groove is then provided and/or foam-filled with extrudates. Finally, the free ends of the extrudates are milled to form the profile of the tongue. Alternatively, or additionally, a groove may also be milled into the extrudates.

Detecting an attack on an authentication service. A first memory area is configured to store data relating to a plurality of requests communicated to an authentication service from a plurality of user agents. A second memory area is configured to store a predefined pattern of one or more requests. The predefined pattern characterizes an attack. A processor searches the stored data as a function of a query variable to identify at least one of the plurality of the requests communicated from at least one of the plurality of the user agents and compares the stored data associated with each of the identified requests with the predefined pattern to determine whether the identified request indicates the attack characterized by the predefined pattern. Other aspects of the invention are directed to computer-readable media for use with detecting the attack on the authentication service.

A polyaxial bone anchor has a headless anchor member (e.g., a screw, hook, or other structure for attaching to bone) that allows the size of the bone anchor to be small. A locking element securely snap-fits over the headless anchor member such that inadvertent separation from the anchor member is unlikely. When the anchor member is attached to the locking element and the locking element is seated within the anchor head of the bone anchor, the headless anchoring member can polyaxially rotate about a central axis of the bone anchor before being locked in place.
