Abstract:
1. An electronic device for use with a stylus, the electronic device comprising: an interactive display screen; a power supply; a housing having an engagement member for releasably engaging the stylus to allow mounting of the stylus to the housing, the engagement member defining a chamber; and an actuator including a protruding member that protrudes into the chamber and is configured to engage the stylus during unidirectional insertion of the stylus into the chamber in a first direction and to disengage the stylus during unidirectional removal of the stylus from the chamber in a second, opposite direction, the actuator also including a normally opan biased switch adapted and arranged to provide an actuation signal indicative of the stylus engaging or disengaging the protruding member; and a controller, operably coupled to the display screen and the acuator, the controller adapted and arranged to provide a signal to activate the display screen in response to the activation signal indicating that the stylus has disengaged the protruding member; and a pull-up resistor coupled at a first terminal to the power supply and coupled at a second terminal to the normally open biased switch and a control input of the controller, wherein the pull-up resistor maintains the control input of the controller at a logic “high” until the stylus engages the protruding member of the actuator.
