Interacting tips for a digitizer stylus
First Claim
1. A stylus comprising:
- a primary tip associated with a first conductor, the first conductor having a first diameter;
a second tip associated with a second conductor, the second conductor having a second diameter that is larger than the first diameter;
a transmitter configured to transmit a first signal with a first amplitude via the first conductor and for transmitting a second signal with a second amplitude via the second conductor, wherein the first amplitude is at least twice the second amplitude; and
wherein the second amplitude together with the second diameter is selected to provide for detecting the second signal with substantially a same signal to noise ratio as compared to the first signal.

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.
