A portable computer apparatus includes a display module, a host module, at least one shaft mechanism, and an antenna. The display module has a first pivot side and includes first and second upper-cover members and a display device contained in the first and second upper-cover members. The host module has a second pivot side and includes first and second lower-cover members and a host device contained in the first and second lower-cover members. The host device is electrically connected to the display device and the antenna. The shaft mechanism is pivotally connected to at least one of the first and second upper-cover members corresponding to the first pivot side and at least one of the first and second lower-cover members corresponding to the second pivot side. The antenna is integrally formed with the shaft mechanism or on one of the first and second pivot sides.

A formulation of conductive putty is disclosed for forming a uniform coating on the surface of a metallic product prior to painting. The formulation of the putty comprises a ketone solvent, epoxy resin, calcium carbonate clay, pigment and metallic powder having a specific conductance. Use of the putty simplifies the finishing procedure, decreases the weight and thickness of the finished product, decreases handling cost and results in a product having an improved appearance.

The present invention provides an apparatus with sound source localization. Spatial information and original audios are synthesized by a mono signal analyzer/synthesizer of a multi-channel system to obtain a three-dimensional (3D) virtual reality sound effect. By extracting and synthesizing spatial parameters, only original audio objects and spatial location data are required to obtain an effect of multi-channel spatial audio. Thus, a multi-channel playback system is formed with a small bit stream in transference to obtain Doppler effect on simulating moving of audio objects in real life.
