US Patent 7483805 Sensing and analysis system, network, and method

A sensing and analysis system, method, and network that make use of a very portable and compact sensor unit and a physically separate electronic unit that serves to power and control the sensor unit, process and optionally display the output of the sensor unit, and transmit the sensor output to other locations, such as over a network. The sensor unit includes a housing, a sensing element within the housing and responsive to an input, and electronic circuitry within the housing and in communication with the sensing element to produce an electrical output based on an output signal generated by the sensing element. A communication providing device delivers instructions generated by the electronic unit to the sensor unit and delivers the electrical output from the sensor unit to the electronic unit.
