An image capturing apparatus realizes a precise focus assist function without losing edge information of a multi-pixel video image. The invention provides for use of a current source, a length, or multiple lengths, of superconducting filament situated within a cryostat containing a cryogenic fluid and a voltmeter for measuring the voltage drop across the filament. A first, ground-based part of the registration includes creating an account for the electronic device that indicates an identification of the electronic device retrieved from a home network of the subscriber. A process for fabricating such a semiconductor device includes forming a thermally conducting structure on a carrier and attaching the thermally conducting structure formed on the carrier to a surface of the semiconductor device via soldering.
