A system, including an alarm which is synchronized with a coffeemaker, is
used to coordinate wake-up time with coffee brewing time. In one
embodiment of the invention, the alarm includes an alarm timer, an alarm
controller, alarm input (e.g., dial or button), a speaker, circuitry for
sound generation and a display. A user sets the alarm timer, and the
speaker is capable of providing a sound to wake the user at the set time.
The circuitry for sound generation is capable of generating a tone and
transmitting the tone with the same speaker. This tone is transmitted to
an electric coffeemaker which includes, a tone receptor (e.g., microphone
and amplifier), and coffee brewing circuitry. The tone receptor receives
the tone generated by the alarm and forwards related data to the coffee
brewing circuitry. The coffee brew cycle is activated in response. The
alarm may be an alarm clock radio and the speaker may transmit an
ultrasonic or audible tone. Moreover, activation of the brew cycle may be
programmed to occur at a specific time before or after the wake-up time.
