1. An exercise monitoring device comprising:
- a strap for releasably securing the exercise monitoring device to a user;
a step counter joined to the strap;
a heart rate monitor joined to the strap; and
a data processor programmed to calculate a distance traveled by multiplying a number of steps counted by the step counter by a stride length that varies according to a rate at which steps are counted.

Abstract
The pedometer having improved accuracy by calculating actual stride lengths of a user based on relative stride rates. The pedometer includes a waist or leg mounted stride counter, a transmitter for transmitting data to a wrist-mounted display unit, and a data processor for calculating necessary base units and actual stride rates and lengths. The pedometer can also interact with a heart monitoring device.

5. An exercise monitoring device comprising:
-
a strap for releasably securing the exercise monitoring device to a user;
a step counter joined to the strap;
a heart rate monitor joined to the strap; and
a data processor programmed to calculate a distance traveled by multiplying the number of steps counted by the step counter by a stride length that varies according to the rate at which steps are counted, and further programmed to derive the stride length from a range of stride lengths calculated from a range of corresponding stride rates calculated from a plurality of calibration samples.

6. A pedometer comprising:
-
a step counter;
a transmitter in communication with the step counter to generate a step count signal corresponding to each step and transmit the step count signal;
a receiver mountable on a user body portion to receive the step count signal transmitted from the transmitter; and
a data processor programmed to calculate a distance traveled by multiplying a number of steps counted by a stride length that varies according to a rate at which steps are taken, and further programmed to derive an actual stride length from a range of stride lengths calculated from a range of corresponding stride rates. - View Dependent Claims (7, 8)
use the range of stride rates to create a corresponding range of stride lengths and compare an actual stride rate to the range of stride rates to derive a corresponding actual stride length.

8. The pedometer of claim 7, wherein the data processor is further programmed to:
interpolate between and extrapolate from the ranges of stride rates and stride lengths to calculate a plurality of additional corresponding stride rates and stride lengths.
