Random Invention Idea

A device that is sewn either into a diaper or underpants for young children. This device uses dissimilar metal wires of a small diameter woven into the material in such a way that they do not contact the skin but when the cloth they are sewn into becomes damp, they will produce a small amount of power that will alert the parent using a light or more likely a low power buzzer.

A second way to accomplish this would be using a small battery that attempts to push a current through similar wires as above to activate a buzzer.

A third way would be using a special stitch that would cause wires to either come together or separate due to the expansion of the diaper as it absorbs liquid.

The whole point of this would be to alert the parent that the diaper is ready for changing. Any additional delay will probably moisten the clothing.

How ESN's Work

ESN's are an 8 digit hexidecimal number or an 11 digit decimal number. Either one represents a 32 bit binary value.

Keep in mind that one digit of HEX equals 4 binary bits.

Manufacturer IDSerial Number
HEX0-F0-F0-F0-F0-F0-F0-F0-F
BINXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
DEC0-25500000000-16777215


For example:
ESN HEX: E6 9F FF FF

The Manufacturer Code is E6 (hex) or 230 (dec).

The Serial Number is 9F FF FF (hex) or 10485759 (dec).

So the decimal ESN is: 23010485759

Conversely, for decimal ESN: 23010485759

The Manufacturer Code is 230 (dec) or E6(hex).

The Serial Number is 10485759 (dec) or 9F FF FF (hex).

So the hex ESN is: E6 9F FF FF
