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 generate and 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 connect and disconnect the circuit at the second end to the second conductive area, wherein the circuit is configured to transmit the signal between the tip and the first conductive area as well as between the tip and the second conductive area as long as the circuit at the second end is connected to the second conductive area and wherein the circuit is configured to transmit the signal between the tip and the first conductive area and to break transmission of the generated signal between the tip and the second conductive area as long as the circuit at the second end is disconnected 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.

14. A method comprising:
-
transmitting a signal that is generated in a stylus via a tip of the stylus, the tip extending from a housing of the stylus, wherein a circuit of the stylus configured to transmit the signal is electrically connected at a first end to the tip and at a second end to a first conductive area substantially surrounding the tip and electrically isolated from the tip; selectively connecting and disconnecting the circuit at the second end to a second conductive area wherein the second conductive area substantially surrounds the tip and is electrically isolated from the tip and the first conductive area; transmitting the signal between the tip and the first conductive area as well as between the tip and the second conductive area as long as the circuit at the second end is connected to the second conductive area; and transmitting the signal between the tip and the first conductive area and breaking transmission of the generated signal between the tip and the second conductive area as long as the circuit at the second end is disconnected to the second conductive area. - View Dependent Claims (15, 16, 17, 18, 19, 20)
