A hook assembly that has particular application for hanging bananas. The peripheral device may be inserted or removed when the portable computer system is powered off, powered on, or in standby or sleep mode. The helical segments in the first set are substantially parallel and have a first pitch forming a first helical angle with respect to the cylindrical axis. A correlation peak is calculated, at a sync detector, using the convolved differential correlations, to detect a frame sync. Responsive to receiving the further input, a list of client specific components and subcomponents, a client specific solution reference architecture, and a set of reference links is produced.
