Abstract

A notification signal, intended to be received by a wireless communication device, is repetitively broadcast by a portable activity-monitoring device that generates user-activity data corresponding to activity of an individual bearing the portable activity-monitoring device. The notification signal conveys information that identifies the portable activity-monitoring device and indicates whether or not the portable activity-monitoring device seeks establishment of a wireless communication link to enable transmission of the user-activity data to the wireless communication device.

2. The portable activity-monitoring device of claim 1 further comprising logic circuitry to determine whether a change in the user-activity data exceeds one or more update thresholds and wherein the communication circuitry to intermittently broadcast the notification signal comprises circuitry to broadcast, within the notification signal, sync information in either a first state or a second state according to whether the logic circuitry determines that the change in the user-activity data exceed the one or more update thresholds.

3. The portable activity-monitoring device of claim 2 wherein the logic circuitry to determine whether the change in the user-activity data exceeds one or more update thresholds comprises circuitry to determine the change in the user-activity data between two points in time and to compare the change to the one or more update thresholds.

a threshold number of ambulatory steps taken, a threshold number of calories expended, a threshold altitudinal transition, a threshold heart rate, a threshold distance traveled, or a threshold rest period.

6. The portable activity-monitoring device of claim 1 wherein the communication circuitry to intermittently broadcast the notification signal comprises circuitry to broadcast, within the notification signal, sync information in either a first state or a second state depending at least in part on the user-activity data.

7. The portable activity-monitoring device of claim 6 wherein the circuitry to broadcast the sync information in the first state or the second state based at least in part on the user-activity data comprises circuitry to broadcast the sync information in the first state if the user-activity data indicates that a predetermined threshold has been exceeded.

8. The portable activity-monitoring device of claim 7 wherein the predetermined threshold corresponds to at least one of ambulatory steps taken, calories expended, altitudinal transition, heart rate, distance traveled, or rest period.

9.

10. The portable activity-monitoring device of claim 1 wherein, if the information indicates that the portable activity-monitoring device does not seek establishment of the wireless communication link, the communication circuitry is further to establish the wireless communication link with the wireless communication device in response to receiving a communication from the wireless communication device indicating that the wireless communication device seeks establishment of the wireless communication link to enable transmission of information to the portable activity-monitoring device.

11. The portable activity-monitoring device of claim 10 wherein the communication circuitry is further to receive the information from the wireless communication device, the information including at least one of the following:

additional user-activity data to be synchronized with the user-activity data generated by the monitoring circuitry, information to be applied to control an operational aspect of the monitoring circuitry, information to be applied to control an operational aspect of the communication circuitry, information to be applied to control an aspect of user-activity data generation within the monitoring circuitry, information to be applied to configure a visual, auditory or haptic output of the portable activity-monitoring device.
