Classification: CPC A  G | IPC A  G

Claim 0:
1. A wearable article, comprising:
a material configured to conform to a body of a wearer;
a plurality of ultrasonic positioning sensors secured with respect to the material at a first set of predetermined locations, a first ultrasonic positioning sensor, of the plurality of ultrasonic positioning sensors, configured to both:
emit a sound wave; and
in response to the emitting of the sound wave, output a first electronic signal that indicates that the first ultrasonic positioning sensor has emitted the sound wave at a first time;

a second ultrasonic positioning sensor, of the plurality of ultrasonic positioning sensors, configured to both:
detect the sound wave emitted from the first ultrasonic positioning sensor; and
in response to the detecting of the sound wave, output a second electronic signal that indicates that the second ultrasonic positioning sensor has detected the sound wave at a second time, the second time being subsequent to the first time;

a feedback device, secured with respect to the material at a second predetermined location, configured to output a feedback signal that is detectable by the wearer of the wearable article according to a predetermined feedback signal sequence;
a processor, configured to:
at a plurality of discrete sequential times, determine positional values of the plurality of ultrasonic positioning sensors based, at least in part, on the first time that the first ultrasonic positioning sensor emitted the sound wave and the second time that the second ultrasonic positioning sensor detected the sound wave; and
cause the feedback device to output the feedback signal corresponding to one of a plurality of predetermined sequences based, at least in part, on a difference between the positional values as determined at the plurality of discrete sequential times and a parameter set of an activity program.
