Although only two of the 65 presenters at Demo Fall 2005 unveiled products designed to enhance sensor technology, Tendril
and Echelon -- and similar sensor companies -- will likely bring more sweeping changes to the tech industry than any of the
other companies showcased at the annual event.
Sensors are small measuring devices that integrate the physical or analog world with the digital world.
Tendril helps bring application development for sensor networks to the huge base of Java and .Net programmers, and it automates
control of vast numbers of sensors from a centralized location. The Tendril Service Broker is a distributed run-time platform
that allows programmers to control sensors by looking at the data they produce rather than having to program changes at a
lower level by addressing each sensor's MAC (media access control) address individually.
Echelon introduced its Pyxos platform, which embeds the Pyxos network protocol inside any machine, sensor, motor, valve, or
actuator.
The result of using just a pair of wires within a machine, rather than wiring every component and sensor separately, will
reduce cost and maintenance while significantly increasing the amount and quality of information coming out.
"The availability of data will transform business and technology and the way we live because it makes it possible to give
a voice to electrically mute devices," said Michael Tennefoss, an Echelon executive.
