a pressure sensor for sensing change in elevation;
a microprocessor for processing signals from the pressure sensor to determine speed corresponding to the change in elevation; and
a display for reporting the speed to a user.
2. The system of claim 1 , further comprising a watch for reporting the speed to a user wearing the watch.
3. The system of claim 1 , the pressure sensor comprising an altimeter.
4. The system of claim 1 , the microprocessor processing the signals and information corresponding to angle of descent to determine speed of descent along a slope.
5. The system of claim 4 , the microprocessor utilizing predetermined angle of descent to determine the speed along the slope.
6. The system of claim 4 , further comprising an inclinometer to measure the angle of descent for the microprocessor.
7. The system of claim 1 , the sensor converting pressure to analog voltage for use by the microprocessor.
8. The system of claim 1 , the microprocessor reading data from the pressure sensor at a fixed rate.
9. The system of claim 1 , the sensor, microprocessor and display configured for attachment to a user.
10. The system of claim 8 , the sensor and microprocessor configured with a common housing.
11. The system of claim 10 , the housing comprising a watch, the display being a display of the watch.
12. The system of claim 1 , further comprising a low pass filter for filtering low frequency data from the pressure sensor.
13. The system of claim 12 , further comprising a high pass filter for filtering high frequency data from the pressure sensor.
14. The system of claim 1 , the pressure sensor and microprocessor configured with a common housing, and further comprising a wireless transmitter configured with the housing, to transmit data indicative of the vertical speed, and further comprising a watch having the display and a wireless receiver configured to receive the data.
