INTERACTING TIPS FOR A DIGITIZER STYLUS
First Claim
1. A stylus comprising:
- a housing;
a tip configured to extend out from the housing, wherein the tip includes a conductive portion;
a first conductive area substantially surrounding the tip and electrically isolated from the tip;
a second conductive area substantially surrounding the tip and electrically isolated from the tip and electrically isolated from the first conductive area;
a circuit configured to transmit a signal via the tip, wherein the circuit is electrically connected at a first end to the tip and at a second end to the first conductive area; and
a switching element configured to selectively connecting the circuit at the second end to the second conductive area.

Abstract
A stylus for use with a digitizer sensor includes a housing confined by a first and second end, a primary tip positioned at the first end of the housing and associated with a first transmitting element, the first transmitting element having a first diameter, a secondary tip positioned at the second end of the housing and associated with a second transmitting element, the second transmitting element having a second diameter that is larger than the first diameter, a transmitting unit for transmitting a first signal with a first amplitude via the first transmitting element and for transmitting a second signal with a second amplitude via the second transmitting element, wherein the first amplitude is at least twice the second amplitude and a powering unit for powering transmission of the first and second signal.
