Abstract: A self-perforating thread-forming screw has a single or multiple thread which is designed for screwing into soft materials such as wood, plywood or composite materials without predrilling.  The screw has a low tightening moment and a high loosening and pull-out moment.  The thread of the screw at the screw tip is shaped to provide good radial displacement of the material with low moments while also contributing to a high retaining force.  Efficient radial displacement of the material at the screw tip as opposed to efficient cutting of the material produces this desired result.

Abstract: Method for enabling a user of a system to obtain access to one or more services, for example for enabling a caller to access some information on a remote server. The method comprises the following steps: the system first prompts the caller to identify himself by entering a subscriber code (121). A speaker verification is then made using a voice comparison between the caller's voice and a voice reference (123) associated with the subscriber the caller claims to be. Access to the requested services is given if the outcome of said voice comparison is positive; if the system does not store a sufficiently good voice reference to verify the identity of the subscriber the user claim to be with a predetermined degree of reliability, the caller is prompted to enter a confidential PIN code (122). If the PIN code entered is correct, access to the requested services is given and a new voice reference is stored.
