An authenticated RFID system is provided that uses elliptic curve cryptography to reduce the signature size and readwrite times when compared to traditional public key implementations such as RSA. The cutter insert is preferably formed of tungsten carbide, except for two exterior surfaces covered with PDC. The embodiment may store these flip-flop states in a computer-readable data structure, such as a file or database. In some embodiments, heat and product gases from the oxidation process can be used, for example, to drive a turbine, reciprocating engine, and injected back into the reaction chamber. A viewer application allows a client to view a video recording side-by-side with a transcript. In another aspect, a serpentine heating element may be mounted to the bottom of the pan along a course that reduces disparity in heating of the upper surface of the pan.
