ABSTRACT:
A pointing device for a portable computer that is integrated into the same package as its power supply which may also be used as an auxiliary power supply for the portable computer. As a result of its use, a portable computer would be able to alternatively draw energy from an alternating current power source, its own direct current power source, or the direct current power source located in the housing of the present invention. As used herein, it is contemplated for the term pointing device to include, but not be limited to, cursor control means such as a mouse having a position tracking processor on its bottom and control buttons on its top; a position tracking processor having adjacent control buttons; a track ball having adjacent control buttons; a glide-point device having adjacent control buttons; a track pad having adjacent control buttons; an optical device using reflected fight sources to measure position or change in position of the cursor; a radio frequency device measuring position or change in position of the cursor depending on changes in phase of radio frequency carders and/or radio frequency modulation; an acoustical device measuring position or change in position of the cursor depending on changes in phase of acoustical carriers and/or acoustical modulation; and a wireless device measuring position or change in position of a cursor.
