Abstract
Abstract A personal fitness monitoring device and a method for assessing the fitness of an individual as the individual exercises includes using a pedometer to determine and output data representing the locomotion of the individual. A heart rate monitor determines and outputs data representing the heart rate of the individual. A determination arrangement calculates the fitness of the individual as the individual exercises using personal data provided by the individual in combination with the data outputs of the pedometer and the heart rate without requiring a predetermined exercise regime. In one embodiment, the pedometer calculates a distance traveled by the individual using personal data provided by the individual. The personal fitness monitoring device may further include a user interface for communicating with the user. The user interface uses a single user controlled selecting mechanism to select a desired one of various user selectable options. The single user controlled selecting mechanism is arranged such that the user selects the desired option by actuating the selecting mechanism during or immediately following the time during which the desired option is being presented by the user interface. The personal fitness monitoring device may also include a predicting arrangement for tracking and predicting the fitness of the individual.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
97 words
A pedometer comprising: an accelerometer for measuring and outputting a plurality of data points representing a corresponding plurality of substantially vertical accelerations caused by each step of an individual as the individual is walking or running; and determination means for calculating the variable distance traveled for each step taken by the individual, the determination means using the combination of step duration and parameters associated with each step derived from the plurality of data points representing a corresponding plurality of vertical accelerations caused by each step to calculate the variable distance for each step taken by the individual.
Claim 2
Dependent Claim
97 words
A pedometer comprising: an accelerometer for measuring and outputting a plurality of data points representing a corresponding plurality of substantially vertical accelerations caused by each step of an individual as the individual is walking or running; and determination means for calculating the variable distance traveled for each step taken by the individual, the determination means using the combination of step duration and parameters associated with each step derived from the plurality of data points representing a corresponding plurality of vertical accelerations caused by each step to calculate the variable distance for each step taken by the individual.
Claim 3
Dependent Claim
33 words
A pedometer according to claim 1, wherein the pedometer further includes a clock for segmenting the output of the accelerometer into a time series of data points representing the output of the accelerometer.
Claim 4
Dependent Claim
90 words
The pedometer according to claim 1, wherein the determination means includes a statistical model descriptive of the variable distance associated with any given step of a broad class of potential users of the pedometer spanning potential user ages, genders, weights, heights, and leg lengths, and across a broad range of speeds of locomotion including both walking and running gaits, said statistical model serving as the means of calibration for the pedometer when the pedometer is provided with personal data regarding the user including age, sex, weight, height, and leg length.
Claim 5
Dependent Claim
47 words
The pedometer according to claim 1, wherein said parameters associated with each step derived from the plurality of data points representing a corresponding plurality of vertical accelerations include maximum acceleration associated with a step, minimum acceleration associated with a step, and average acceleration associated with a step.
Claim 6
Independent Claim
103 words
A method of calculating a distanced traveled by an individual as the individual is walking or running, the method comprising the steps of: using an accelerometer, measuring and outputting a plurality of data points representing a corresponding plurality of substantially vertical accelerations caused by each step of the individual as the individual is walking or running; and calculating a variable distance traveled for each step taken by the individual using the combination of step duration and parameters associated with each step derived from the plurality of data points representing a corresponding plurality of vertical accelerations caused by each step taken by the individual.
Claim 7
Independent Claim
103 words
A method of calculating a distanced traveled by an individual as the individual is walking or running, the method comprising the steps of: using an accelerometer, measuring and outputting a plurality of data points representing a corresponding plurality of substantially vertical accelerations caused by each step of the individual as the individual is walking or running; and calculating a variable distance traveled for each step taken by the individual using the combination of step duration and parameters associated with each step derived from the plurality of data points representing a corresponding plurality of vertical accelerations caused by each step taken by the individual.
Claim 8
Dependent Claim
70 words
A method according to claim 5, wherein the step of using an accelerometer to measure and output a plurality of data points representing a corresponding plurality of vertical accelerations caused by each step of the individual as the individual is walking or running includes the step of using a clock to segment the output of the accelerometer into a time series of data points representing the output of the accelerometer.
Claim 9
Dependent Claim
106 words
A method according to claim 5, wherein the step of calculating the variable distance traveled for each step taken by the individual includes the step of using a statistical model descriptive of the variable distance associated with any given step of a broad class of potential users of the pedometer spanning potential user ages, genders, weights, heights, and leg lengths, and across a broad range of speeds of locomotion including both walking and running gaits, said statistical model serving as the means of calibration for the pedometer when the pedometer is provided with personal data regarding the user including age, sex, weight, height, and leg length.
