A voltage regulator circuit arrangement limits the DC voltage applied to a tip and ring amplifiers of a subscriber line interface circuit, each of which has a first polarity input coupled to a first current flow path to which a DC input voltage is coupled. A second relative timing relationship of the phase of the data signal to a phase of a second phase clock is determined, and the first and second phase clocks have a 45\xb0 phase difference. The electrical circuits are formed on the image sensing chip, each of the electrical circuits is formed with bonding pads and is electrically connected to the transparent layer by way of flip chip bonding. A software update may also be transmitted to the packaged device. The brace may also provide a mask stabilizing portion. Additionally, the embodiment involves estimating, for each attribute in the test image, an attribute value based at least in part on information stored in a metadata associated with each of the object images.
