1. A method of inserting extra information in an input signal, comprising:
converting the input signal in a first domain, which is human perceptible, into a representation in a second domain different from the first domain;
generating a watermark comprising the extra information; and
outputting a watermark signal representing the watermark to the first domain for merging the watermark signal with the input signal.
2. A method as claimed in claim 1, where the first domain is one of an acoustic domain and a visual domain.
3. A method as claimed in claim 1, where the second domain is an electrical domain.
4. A method as claimed in claim 1, where the watermark is generated based on the input signal.
5. A method as claimed in claim 1, where the watermark signal is output towards a source of the input signal.
6. A method as claimed in claim 1, where the watermark signal is output on a surface of a source of the input signal.
7. A computer-implemented device for inserting extra information in an input signal, comprising:
receiving means for converting the input signal in a first domain, which is human perceptible, into a representation in a second domain different from the first domain;
generating means for generating a watermark comprising the extra information; and
output means for outputting a watermark signal representing the watermark to the first domain for merging the watermark signal with the input signal.
8. A computer program, embedded on a computer-readable medium, for causing a processor to convert the input signal in a first domain, which is human perceptible, into a representation in a second domain different from the first domain; to generate a watermark comprising the extra information; and to output a watermark signal representing the watermark to the first domain for merging the watermark signal with the input signal.
9. A method comprising:
receiving a human-perceptible signal;
generating an electrical signal that represents the human-perceptible signal;
generating, based on the electrical signal, a first watermark signal in an electrical domain;
generating, based on the first watermark signal, a second watermark signal in a human-perceptible domain; and
combining the second watermark signal and the human-perceptible signal to generate a watermarked human-perceptible signal.
10. The method of claim 9, wherein the human-perceptible domain is an acoustic domain.
11. The method of claim 9, wherein the human-perceptible domain is a visual domain.
12. The method of claim 9, wherein the human-perceptible signal is generated by a source including a person.
13. The method of claim 12, wherein the second watermark signal is generated by a device that is worn or carried by the person.
14. The method of claim 9, wherein a source of the human-perceptible signal includes a surface, and the combining includes projecting the second watermark signal onto the surface.
15. The method of claim 9, wherein the second watermark signal is imperceptible or unobtrusive in the watermarked human-perceptible signal.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A cooling device comprising:
a first member having at least a wick as a component of a heat pipe;
a second member physically separated from the first member and provided with a condenser as a component of the heat pipe, the first member and the second member having grooves made of at least one of a metal and a material having a thermal conductivity substantially equal to that of a metal; and
a flexible substrate interposed between the first member and the second member and having a flow-path formed therein so as to connect the wick and the condenser to each other,
the flow-path formed in the flexible substrate has a diamond-like carbon film formed therein, wherein
at least one of the first member and the second member being made of a polyimide resin.
