  • Patent number: 5212672
    Abstract: A timing control apparatus for selectively actuating at least one remote device, such as a variable intensity lamp, an audio device or an aroma generator at a selected future time, by generating a plurality of clock pulses of a known time duration at the selected time, and by counting the clock pulses to gradually increase the intensity of electrical current in response to the clock pulses counted, from an initial zero state to full intensity over time, such as one hour. The gradual increase in intensity provides a gradual increase in the light, sound or smell from selected remote devices, to gently awaken a user, without an abrupt on/off actuation found in alarm clocks, and other similar devices.
