Marker

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.
