The present invention relates to a hinge frame for a portable computer and a structure for mounting the same. Because a stray field concentrates on a magnetic field element, a symptom in which already recorded data is erased is prevented. The present invention further includes methods of making and using the solid dose delivery vehicle of the invention. In a further embodiment, the modulation of signals, data types carried by the signals, and estimated signal origins may be identified. The supporting structures may be used to form moisture barriers in between two modules, such as side glitters.
