Interacting tips for a digitizer stylus |
| 摘要 |
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. |

1. A stylus for use with a digitizer sensor, the stylus comprising:
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, the powering unit including a battery, wherein the second amplitude together with the second diameter is selected to reduce expenditure of the battery for transmitting the second signal as compared to expenditure for transmitting the first signal and to provide for detecting the second signal with substantially a same signal to noise ratio as compared to the first signal. |
