Abstract: A system for facilitating an electronic signature of a document such as a death certificate includes a voice authentication unit, a voice recognition and a database for storing information relating to the electronic signature ceremony. The system includes an enrollment interface to telephonically receive a reference voiceprint from a future signer of the death certificate, for example a physician. The system is further configured to receive an authentication voiceprint from the enrolled physician wherein the voice authentication unit compares the reference voiceprint and the authentication voiceprint to confirm identity. The system employs the voice recognition unit to allow the physician to telephonically perform at least one of the functions selected from the group including (i) identifying the death certificate, (ii) entering data into the death certificate, or (iii) affirming data that is in the death certificate.

Abstract: An electrical discharge machine includes a chuck for holding an electrode above a workpiece. A lower guide positions a tip of the electrode above the workpiece, and mid-guide laterally supports the electrode between its opposite ends for reducing flexing therebetween.

Abstract: In the electrochemical drilling of a hole completely through a workpiece, the present invention proposes operating the power supply in a current regulating mode. Initially, a hollow cathode is positioned adjacent to a workpiece in which one or more holes are to be drilled. An electrolyte is flowed through the cathode and against the workpiece. A constant electrical current is applied between the cathode and the workpiece across the electrolyte. Then the cathode is advanced at a constant rate toward the workpiece for the drilling of the hole(s), while maintaining the electrolyte flow and current substantially constant.
