The U.S. Patent and Trademark Office has today granted Apple a new patent titled “Shoe wear-out sensor, body-bar sensing system, unitless activity assessment and associated methods”, that details a weightlifting tracking system which uses a standalone sensor to transmit metrics to a remote display, such as an ‘iWatch’, AppleInsider is reporting.
Apple’s invention includes a wrist watch for remote readings, possibly hinting at an intended use of the much-rumored ‘iWatch’. The document describes a sensor-laden device that attaches itself to a weightlifting bar and counts and displays repetitions. The device can incorporate sensors, accelerometers, processors and its own onboard display. The same readings can also be uploaded wirelessly to a user’s watch.
“Sensor hardware clips on to the appropriate fitness equipment, whether it be a bar, dumbbell or machine apparatus, and takes movement readings to count proper repetitions. In some instances, the sensor package is a standalone unit that can be transported from one piece of equipment to the next, while other embodiments provide for a semi-permanent solution like a bar clamp. Most gyms provide spring-loaded or standard clamps to keep weights from sliding off the bar during rigorous exercise.”
