Abstract

A wake-up device for generating a control signal is presented. The wake-up device comprises a sensor for detecting an input signal, that comprises at least one knock, and an electrical circuitry for processing the detected input signal and generating said control signal. Further, a method for generating a control signal from a wake-up device is also presented.

Claims

1. A wake-up device for generating a control signal comprising

a sensor for detecting an input signal, that comprises at least one knock, and

an electrical circuitry for processing the detected input signal and generating said control signal.

2. A wake-up device according to claim 1, wherein said sensor is selected from the group consisting of acoustic sensors and vibration sensors.

3. A wake-up device according to claim 2, wherein said sensor is selected from the group consisting of microphones and accelerometers.

4. A wake-up device according to claim 1, wherein said electrical circuitry is configured to detect at least one of the signal intensity, the number of knocks, and the frequency distribution of the input signal.

5. A wake-up device according to claim 1, wherein said electrical circuitry comprises a filter for filtering the input signal.

6. A wake-up device according to claim 5, wherein said filter is a band pass filter.

7. A wake-up device according to claim 1, wherein said electrical circuitry is configured to apply a predetermined criteria to the detected input signal for deciding whether or not the control signal should be generated.

8. A method for generating a control signal from a wake-up device, comprising the steps of

detecting at least one knock as an input signal,

processing the detected signal, and

generating said control signal.

9. A method according to claim 8, further comprising detecting at least one of the signal intensity, the number of knocks, and the frequency distribution of the input signal.

10. A method according to claim 8, further comprising filtering the detected input signal.

11. A method according to claim 10, further comprising filtering the detected input signal by means of a band pass filter.

12. A method according to claim 8, further comprising applying a predetermined criteria to the detected input signal for deciding whether or not the control signal should be generated.
