Patent ID: 7637794

Claim:
A toy, comprising: a body; a breath sensor, the breath sensor being coupled to the body at a first location, the breath sensor being configured to detect the presence of breath proximate to the first location by detecting the value of one of humidity and temperature proximate to the body, the breath sensor being configured to generate an electrical characteristic relative to the value detected by the breath sensor; a reference sensor, the reference sensor being coupled to the body at a second location, the second location being spaced apart from the first location, the reference sensor in the second location being protected from any breath to which the breath sensor at the first location is exposed, the reference sensor being configured to detect the value of one of humidity and temperature proximate to the body and to generate its own electrical characteristic relative to the value detected by the reference sensor; an output device, the output device being configured to produce an output; and a processor, the processor being operatively coupled to the breath sensor, to the reference sensor, and to the output device, the processor being configured to compare the electrical characteristic of the breath sensor to the electrical characteristic of the reference sensor, the processor being configured to activate the output device if the electrical characteristics of the breath and reference sensors differ by a predetermined amount.
