Classification: CPC A  G | IPC A  G

Claim 7:
8. A method, comprising:
receiving, with a processor and via a first ultrasonic positioning sensor, of a plurality of ultrasonic positioning sensors, a first electronic signal indicating that the first ultrasonic positioning sensor has emitted a sound wave at a first time;
receiving, with the processor and via a second ultrasonic positioning sensor, of the plurality of ultrasonic positioning sensors, a second electronic signal indicating that the second ultrasonic positioning sensor has detected the sound wave emitted from the first ultrasonic positioning sensor at a second time subsequent to the first time;
determining a direction that the sound wave was detected by the second ultrasonic positioning sensor;
based at least in part on the first ultrasonic positioning sensor having emitted the sound wave at the first time and the second ultrasonic positioning sensor having detected the sound wave at the second time and the determining of the direction, determining, with the processor, at a plurality of discrete sequential times, positional values of the plurality of ultrasonic positioning sensors secured with respect to a material at a first set of predetermined locations, wherein the material is configured to conform to at least a torso of a body of a wearer, and wherein at least one of the plurality of ultrasonic positioning sensors are in a location in the material corresponding to the torso of the body; and
for at least the location, causing, with the processor, a feedback device to output a 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.
