Abstract: A pressboard for high-voltage devices is disclosed. The pressboard has a density of 0.6-1.3 g/cm3 according to IEC60641-2, and includes 1-15% microfibrillated cellulose (MFC) based on the total dry weight of the pressboard. The pressboard also includes an insulation element. For example, the pressboard is impregnated with an electrically insulating compound. The insulation element may be used in a high-voltage device, such as a power transformer.

Abstract: The invention relates to a method for enhanced voiceprint authentication. The method includes receiving an utterance from a user, and determining that a portion of the utterance matches a pre-determined keyword. Also, the method includes authenticating the user by comparing the portion of the utterance with a voiceprint that is associated with the pre-determined keyword. Further, the method includes identifying a resource associated with the pre-determined keyword while comparing the portion of the utterance with the voiceprint. Still yet, the method includes accessing the resource in response to authenticating the user based on the comparison.
