ABSTRACT:
TECHNICAL FIELD
This application relates generally to portable electronic communications devices and, more specifically, to cellular telephones with data acquisition capabilities.
BACKGROUND
Modern automobiles come with many amenities. One of the most popular options in come cars is an inside/outside thermometer. For example, high-end BMW automobiles are equipped with a dual thermometer that reads the temperature both inside the vehicle as well as the ambient outside temperature. The inside temperature can be used to set the climate control system. With a touch of a button, the driver can see either the outside temperature or the inside temperature. A quick comparison reminds the driver how lucky he is to have such a fancy car.
The popularity of this feature is due in part to the innate desire to know the temperature. On any given summer's day in Atlanta, Ga., where it gets really hot, you are bound to hear people talking about the heat. One might say, “Man, it sure is hot out here! It's a hundred and five if it's a degree!” In response, another might say, “I'll bet that it's not more than a hundred and two.” After this, friendly wagering is likely to ensue.
There are a couple of ways to settle this argument. The first is to listen to the radio for the temperature. The problem with this solution is that mainstream radio stations only announce the temperature once or twice an hour. Consequently, our friends may have to bear the heat and risk their health for thirty minutes or more to find out the temperature.
The other solution is to look at a thermometer. The problem with this solution is that most outdoor thermometers are big and bulky, and not conducive to being carried in a pocket. There is thus a need for an improved temperature measurement system.
