A live trap and cage assembly has a base, opposing sidewalls and a central main support section. A rate of change of the position of the steering mechanism is determined. A partially completed integrated circuit with a ferroelectric thin film precursor material may be placed between two electrodes in an annealing apparatus and voltage sufficient to polarize the ferroelectric thin film material in the direction of the electrical field is supplied to the electrodes during the anneal and as the film cools. Data is archived, updated and exchanged without being corrupted. The methods may be practiced with the diagnostic kits of the invention.
