Throughout the years during which these health-related patents were developed, Apple Inc. (NASDAQ:AAPL) has mostly removed the references to sensors that track show wear-out and unitless measurements. However, the company has left in the “body-bar sensing system,” along with the readout that’s meant for a watch.

How the iWatch patent might work

This newest patent describes a system that enables a device that’s equipped with sensors to attach itself to a weightlifting bar. The system then counts repetitions and displays them to the user. Apple Inc. (NASDAQ:AAPL) itself has added the use of a watch to offer remote readings. This seems to suggest that the system could have a future in the rumored iWatch.

The device that attaches to the weightlifting bar could have a number of accelerometers, Hall Sensors, processors and a display. The watch would then calculate the numbers and display the user’s progress wirelessly. Apple Inc. (NASDAQ:AAPL) describes the device that attaches to the weightlifting bar as either a portable unit that can be moved to each piece of exercise equipment as the user moves through the gum. The company also includes a more permanent version of the device that’s attached to the weightlifting bar using a clamp and stays with the equipment.

What the system might show

Throughout the user’s workout, they can view numerous metrics through a watch, including the amount of time between each movement. The watch can then compare these metrics with previous recorded metrics to show the user how much progress they are making.
