A quasi-resonant device for a switching power, a quasi-resonant system for a switching power, and a method for a quasi-resonant control of a switching power are provided. The multidirectional turn-signal lamp indicates three directions of turns-front side, rear side and lateral side. In an illustrative embodiment, a first portion of the thread identifier is utilized to select one of a plurality of multiple-bank memory elements within the memory, and a second portion of the thread identifier is utilized to select one of a plurality of memory banks within the selected one of the multiple-bank memory elements. The elastomeric strip extends along the longitudinal axis and connects the first side section and the second side section to be of unitary construction with the first and second side sections. A sphericity ratio is computed that compares the test utterance model to the target speaker model, as well as a background model. The equipment further includes blowers and lights mounted on an upper part of the vehicle wherein the balloon is bottom-opened box shaped and made of a sheet displaying thereon an image andor message and having its lower part fixed to the upper part of the vehicle.
