Embodiments of the invention provide a pen-stylus that comprises a first antenna having a hemispherical shape at a proximal end of the pen-stylus where the pen-stylus engages with a display of a tablet device. The pen-stylus also includes a second antenna, wherein the first antenna and the second antenna communicate with the tablet device to enable a pen-stylus user to draw on the display of the tablet device. The pen-stylus additionally includes an insulating material between the first antenna and the second antenna that prevents interference between the first antenna and the second antenna. In some embodiments, the first antenna and the insulating material reside in a marker tip attached to the pen-stylus, the marker tip transmits axial forces received by engagement of the pen-stylus with the display on the tablet to a force sensor. The pen-stylus further includes a force sensor that converts axial forces received from the marker tip into an electrical signal and transmits the electrical signal to the tablet by at least one of the first antenna and the second antenna.

Marker writing system

Embodiments of the invention provide a removable marker tip configured for application with an active pen-stylus. The removable marker tip comprises an antenna and an insulator and is designed to be held onto the pen-stylus' writing shaft by a set of crush ribs fitted into a posterior recess on the removable marker tip. The removable marker tip is designed to be a consumable part to improve the paper feeling received by users of the pen-stylus as they draw on the display of a tablet device. The removable marker tip is further designed to be hand-removable by users of the pen-stylus.

Replaceable conductive marker tip

Embodiments of the invention provide an improved structure and method for determining the tilt angle associated with the erasure component of an active pen-stylus relative to the display on a matching computing device by analysis of two different antenna signals associated with the erasure function and then employing this calculated tilt angle to determine an area of erasure on the display device associated with the active pen-stylus. Embodiments of the invention may effectively copy in an electronic eraser, the ability of a conventional rubber eraser to control an area of erasure based on the tilt of the eraser, e.g., a heavy area of erasure when the eraser is held at an angle or a shallow area of erasure when the eraser is held in a more upright position.
