The strap assembly has a sensor that senses a change in dimension of the strap assembly while the strap assembly is wrapped around the body part and provides a sensor output. A processing unit coupled to the sensor receives the sensor output and provides a measurement output. A display that receives the measurement output and provides a measurement output reading correlating to the measurement output. ## Claims ### Claim 1 A wearable fitness band system that measures a body part change in dimension, the device comprising: a wearable fitness band device comprising strap assembly that is configured for being wrapped around the circumference of a body part to be measured, the strap assembly having a sensor that senses a change in dimension of the strap assembly while the strap assembly is wrapped around the body part and provides a sensor output; a processing unit coupled to the sensor for receiving the sensor output and providing a measurement output; and a display that receives the measurement output and provides a measurement output reading correlating to the measurement output. ### Claim 2 (depends on 1) The system of claim 1, wherein: the sensor is an elastomeric stretch sensor. ### Claim 3 (depends on 2) The system of claim 2, wherein: the elastomeric stretch sensor constitutes a section of the strap assembly, with the remainder of the strap assembly being non-stretchable. ### Claim 4 (depends on 1) The system of claim 1, wherein: the display is provided on at least one of a display of the wearable fitness band device and a separate mobile device. ### Claim 5 (depends on 1) The system of claim 1, wherein: the wearable fitness band device further comprises a band position sensor that receives a position coupling when the strap assembly is wrapped around the body part to facilitate determining a reference dimension of the strap assembly. ### Claim 6 (depends on 1) The system of claim 1, wherein: wearable fitness band device further comprises a removable band spacer that facilitates selective shortening and lengthening of the strap assembly. ### Claim 7 (depends on 5) The system of claim 5, further comprising: a removable band spacer that facilitates selective shortening and lengthening of the wearable band assembly, and wherein the position coupling is provided on the band spacer. ### Claim 8 (depends on 1) The system of claim 1, wherein: the system provides a real-time measurement output that is displayed on the display. ### Claim 9 (depends on 1) The system of claim 1, wherein: the display selectively provides at least one of a reverse, a rotated, and an upside-down image display. ### Claim 10 (depends on 1) The system of claim 1, wherein: the wearable fitness band device accommodates body parts ranging from 8 inches to 50 inches in circumference. ### Claim 11 (depends on 1) The system of claim 1, wherein: the wearable fitness band device measures a change in dimension of from 0.01 inch or more. ### Claim 12 (depends on 1) The system of claim 1, wherein: the wearable fitness band device provides text at least one of messaging, emailing, phone calling, web surfing, accessing an electronic personal assistant, fitness tracking, photo display, video display, GPS tracking, step counting, heart rate monitoring, sleep statistics, time and date display, haptic feedback, music play, and audio play. ### Claim 13 A wearable fitness band system that measures a body part change in dimension, the system comprising: a wearable fitness band device comprising a strap assembly that is configured for being wrapped around the circumference of a body part to be measured, the strap assembly comprising: a length of elastomeric stretch sensor that senses a change in dimension of the strap assembly when the elastomeric stretch sensor is expanded and retracted; at least one removable band spacer having a known length, the band spacer having a position coupling fixed thereon; and a band spacer position sensor that is configured to engage the position coupling of the at least one removable band spacer at different positions along the length of the band spacer position sensor; and a processing unit coupled to the strap assembly for providing a measurement output in response to receiving an output signal from the elastomeric stretch sensor; and a display coupled to the processing unit that receives the measurement output and provides an output on the display correlating to the measurement output. ### Claim 14 (depends on 13) The system of claim 13, wherein: the display is provided on at least one of a display of the strap assembly and a separate mobile device. ### Claim 15 (depends on 13) The system of claim 13, wherein: there are at least two interchangeable band spacers of different lengths that facilitate shortening and lengthening of the strap assembly. ### Claim 16 (depends on 13) The system of claim 13, wherein: the system provides a real-time measurement output that is displayed on the display. ### Claim 17 (depends on 13) The system of claim 13, wherein: the display selectively provides at least one of a reverse, rotated, and upside-down image display. ### Claim 18 (depends on 13) The system of claim 13, wherein: the strap assembly accommodates body parts ranging from 8 inches to 50 inches in circumference. ### Claim 19 (depends on 13) The system of claim 13, wherein: the system measures a change in dimension of from 0.01 inch or more. ### Claim 20 A method of measuring a change in circumference of a body part comprising: positioning a wearable fitness band device that is configured for being wrapped around the circumference of a body part to be measured; sensing with a sensor of the wearable band device a change in dimension of the wearable fitness band device while the wearable band is wrapped around the body part; providing a sensed output that correlates to the sensed change in dimension; and displaying on a display device a measurement output based upon the sensed output.
