| 发明名称 | Passive pen with ground mass state switch | ||
| 摘要 | A passive pen includes a pen body, and a tip disposed at a first end of the pen body. The tip capacitively couples to the pen body, and the capacitive coupling is configured to change the tip from a first ground mass state to a second ground mass state. | ||

| 主权项 | 1. A passive pen comprising: a pen body; and a tip disposed at a first end of the pen body, wherein the tip capacitively couples to the pen body and the capacitive coupling is configured to change and switch the tip from a first ground mass state to a second ground mass state; and a compressible non-conductive substance between the tip and the pen body, wherein the compressible non-conductive substance is compressed, relative to a compression level of tip in a first position, when the tip is in a second position. | ||
