1. An apparatus comprising:
- a timer;
a signal generator;
a signal activator input;
a switch configured to couple a power source to the signal generator and the timer; and
a controller comprising one or more computer-readable non-transitory storage media embodying logic that is operable when executed to;
initiate the coupling, in response to an actuation of the signal activator input, of the power source to the signal generator to thereby cause the signal generator to generate a signal; and
initiate the coupling, in response to the actuation of the signal activator input, of the power source to the timer to thereby activate the timer.

Abstract
In one embodiment, an apparatus includes a timer, a signal generator, a signal activator input, and a controller. The controller includes one or more computer-readable non-transitory storage media embodying logic that is operable when executed to initiate a coupling, in response to an actuation of the signal activator input, of a power source to the signal generator to thereby cause the signal generator to generate a signal. The logic is further operable to initiate a coupling, in response to the actuation of the signal activator input, of the power source to the timer to thereby activate the timer.

8. A controller comprising:
one or more computer-readable non-transitory storage media embodying logic that is operable when executed to; initiate a coupling, in response to an actuation of a signal activator input of a stylus, of a power source to a signal generator of the stylus to thereby cause the signal generator to generate a stylus signal; and initiate a coupling, in response to the actuation of the signal activator input, of the power source to a timer to thereby activate the timer, wherein a switch is configured to couple the power source to the signal generator and the timer. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method comprising:
-
initiating a coupling, in response to an actuation of a signal activator input of a stylus, of a power source to a signal generator of the stylus to thereby cause the signal generator to generate a stylus signal; and initiating a coupling, in response to the actuation of the signal activator input, of the power source to a timer to thereby activate the timer, wherein a switch is configured to couple the power source to the signal generator and the timer. - View Dependent Claims (16, 17, 18, 19, 20)
