1. An efficient sensing system comprising:
- first means for sensing an object;
second means for sensing the object; and
third means for selectively polling said second means a plurality of times upon receipt of a signal from said first means, wherein said first means is an early warning sensor, and said second means is an accurate sensor, and wherein said third means includes a controller in communication with said accurate sensor and said early warning sensor, said controller polling said accurate sensor at a sampling rate in response to said signal.

Abstract
An efficient sensing system. The efficient sensing system includes a first mechanism for sensing and a second mechanism for sensing. A third mechanism selectively polls the second mechanism upon receipt of a signal from the first mechanism. In a specific embodiment, the first mechanism includes an early warning sensor, and the second mechanism includes an accurate sensor. In the specific embodiment, the third mechanism includes a controller in communication with the accurate sensor and the early warning sensor. The controller samples the accurate sensor at the sampling rate in response to the signal.
