The present invention relates to novel polyesterpolyols with cyclic imide structure and to their use in coating compositions. A method may include allowing upper layer software to transparently access the capabilities of a network device via a virtual interface as if the network device were in a computing device in which the upper layer software is resident. The calculation of the carry bit out of each bitslice is limited to the operands bits into that bitslice and the three preceding bitslices. The drop link is rotated clockwise about the first hinge.
