Abstract

Described is a hardware implementation to provide a means of providing a negative battery contact at the positive end of a hand held stylus, as used with Personal Computer (PC) screens. The implementation described involves the design of metal parts that are shaped to fit within a hand held stylus, but can also be used in other products.

Negative Battery Contact Device for a Stylus

      Described is a hardware implementation to provide a means of
providing a negative battery contact at the positive end of a hand
held stylus, as used with Personal Computer (PC) screens.  The
implementation described involves the design of metal parts that are
shaped to fit within a hand held stylus, but can also be used in
other products.

      The design involves a hand held stylus that provides the
battery negative contact to be brought up to the front, or positive,
section of a stylus.  The concept described herein provides
mechanical parts to bring the negative contact from the back of a
battery to the front end adjacent to where the positive contact is
located.

      Fig. 1 shows an exploded isometric view of the various parts
which make up the stylus with the negative contact at the front end.
Metal washer 10 is designed to provide the contact to the negative
section of the battery.  Z-shaped metal part 11 is designed to
provide the contact to the positive section of the battery.  Both
metal washer 10 and Z-shaped metal part 11 are attached to a small
printed circuit board (not shown).  Insulating material (not shown)
is added between the two contacts to insure that shorting will not
occur.  Fig. 2 shows an isometric view of metal washer 10 used for
the negative contact and Fig. 3 shows an isometric view of Z-shaped
metal part 11 used for the positive contact.
