1. A wrist-worn device that monitors movements of a user comprising:
- a sensor assembly configured to detect movement of the user and generate sensor data based on the movement detected;
a controller connected to the sensor assembly that obtains movement data based, at least in part, on the sensor data; and
an antenna connected to the controller that is configured to operate at a desired frequency when a wrist of the user is received by the device such that the movement data is wirelessly transmittable from the wrist-worn device to an electronic device;
wherein the desired frequency is a peak resonant frequency, the antenna is tuned such that the antenna operates at an off-peak resonant frequency relative the peak resonant frequency when the wrist is not received by the wrist-worn device, and the antenna produces a radiation pattern having relatively high gain areas that are directed away from a body of the user when wirelessly transmitting the movement data;
wherein a body of the wrist-worn device includes a plurality of flex areas and the wrist-worn device further comprisesan internal spine member extending through the body of the wrist-worn device, anda flexible circuit member wrapped around and connected to the spine member, the flexible circuit member interconnects the controller and one or more sensors of the sensor assembly; and
wherein the antenna is connected to the flexible circuit member and at least a portion of the antenna is located in one of the flex areas of the body of the wrist-worn device.

Abstract
A wrist-worn device monitors movements of a user. A sensor assembly of the wrist-worn device is configured to detect movement of the user and generate sensor data based on the movement detected. A controller connected to the sensor assembly obtains movement data based on the sensor data. An antenna connected to the controller is configured to operate at a desired frequency when a wrist of the user is received by the device such that the movement data is wirelessly transmittable from the wrist-worn device to an electronic device. The antenna may exhibit a different design and configuration depending on the size of the wrist-worn device.

15. An antenna for a wrist-worn device that monitors movements of a user comprising:
-
an antenna configuration that causes the antenna to operate at a desired frequency when a wrist of the user is received by the device such that movement data collected by the wrist-worn device is wirelessly transmittable to an electronic device; wherein the antenna configuration causes the antenna to produce a radiation pattern having relatively high gain areas that are directed away from a body of the user when wirelessly transmitting the movement data; and wherein the antenna is configured to be embedded in a flexible circuit member of the wrist-worn device when installed in the wrist-worn device such that at least a portion of the antenna is positioned in a flex area of the wrist-worn device when embedded in the flexible circuit member. - View Dependent Claims (16, 17, 18)
