Activity monitoring systems and methods
View Patent ↗An activity monitor, comprises housing for attachment to a person; at least one accelerometer disposed within the housing; and a processor disposed within the housing, for processing signals from the accelerometer to assess activity of the person. A method assesses activity of a person, including: sensing acceleration at a first location on the person; processing the acceleration, over time, to assess activity of the person; and wirelessly communicating information indicative of the activity to a second location.

assess boundary conditions of the transducer output;
exclude certain conditions of the transducer output; and
determine the characteristics of the user's workout from the processed transducer output in real time, wherein the output of the transducer comprises a vibrational spectrum related to movement of the user during a workout.
2. The receiver of claim 1 , wherein the determined characteristics of the user's workout comprise at least one of:
speed;
peak speed;
average speed;
distance traveled;
loft time;
pulse;

the processor is operative to perform an integration on the acceleration over time to determine the speed characteristic of the user's workout.
9. The receiver of claim 1 , wherein:
the output of the transducer expresses acceleration related to movement of the user during a workout; and
the processor is operative to perform a double integration on the acceleration over time to determine the distance traveled characteristic of the user's workout.
10. The receiver of claim 1 , further comprising:
a housing attached to the user and operative to house the receiving element and processor.
11. A system for communicating data associated with a user's workout comprising:
a transmitter comprising:
a transducer operative to detect movement of a user during a workout; and
a transmitting element operative to transmit data related to movement detected by the transducer as the movement is detected; and
a receiver comprising:
a receiving element operative to receive the data transmitted by the transmitting element;
a processor operative to assess boundary conditions of the received data and exclude certain conditions of the received data that correspond to particular movements of the user during a workout to generate characteristics of the user's workout from the received data in real time, wherein the received data comprises a vibrational spectrum related to movement of the user during the workout; and
a display operative to display the characteristics of the user's workout in real time.
12. The system of claim 11 ; wherein the characteristics of the user's workout comprise at least one of:
