A system and method are provided for validating a signature on a touchscreen using a smart stylus. Software residing on a touchscreen device disables touch input from sources other than the stylus. In one embodiment, the stylus wirelessly transmits a stylus identifier to the touchscreen device to identify the stylus to the device. The stylus may also have a stylus tip that produces an encoded voltage pulse sequence that is used to identify the stylus to the device. A stylus ID is associated with an encoded voltage pulse. The touchscreen device can look up the stylus ID in a database, determine the encoded voltage pulse associated with the stylus ID, and determine that a voltage pulse transmitted by the stylus tip is the pulse associated with the stylus ID, thus validating the source of data input on the touchscreen.

A magnetically connected universal computer power adapter is presented. The computer power adapter provides a power supply, a power cord, a cord connector, and a charging plug. The cord connector and charging plug each contain a magnet that magnetically couple the cord connector to the charging plug. The cord connector may couple with more than one type of charging plug, allowing the universal computer power adapter to be used with many different computer models.

A grip-enabled touchscreen stylus for teaching a proper writing grip comprises a stylus shaft and a stylus tip for writing on a capacitive touchscreen electronic device. Three buttons situated around the stylus shaft activate the stylus tip. The stylus has a normally-off state, in which the tip is disabled and cannot interact with a touchscreen. When a thumb, index, and middle finger of a hand correctly grip the stylus by pressing all three buttons simultaneously, an actuator within the stylus causes the tip to activate in order to interact with the touchscreen. The stylus actuator may be mechanical, electronic, or electromechanical. The stylus may be supplemented by software or logic on the touchscreen-enabled device enabling the desired user experience of requiring proper grip on the stylus for touchscreen input to be validated.
