Abstract:
1. A fluid loss monitoring pedometer device, comprising: a) a housing having a keyboard and a display screen; b) an ambient temperature sensor; c) an ambient humidity sensor; d) a stride counting apparatus; e) a timing apparatus; and f) a microprocessor; wherein the microprocessor calculates speed of movement from stride count, stride length and elapsed time; and wherein speed of movement is used by the microprocessor to calculate total caloric expenditure for a given duration; and wherein the microprocessor uses total caloric expenditure to calculate fluid loss using the equation: wherein time units are in percent of an hour, J is a value selected from 1250-1290 and K is a value selected from 1610-1650; and wherein the display screen indicates the calculated fluid loss.
