Anax (formerly Project BZ)



The purpose of this project is to develop a consumer-targeted, wearable, bluetooth inertial sensor for use in joint monitoring applications. The system involves a gyroscope, an accelerometer, and a magnetometer. The data from these sensors is processed with a simplified Kalman filter for lower processor load on iOS devices. The sensor will connect to an iOS application that will allow visualization of the joint movement at up to 100 data points per second. This product sees applications in the physical therapy, medical, and wearable technology markets. Once completed, the product will be integrated into the BZ system.

Project BZ II will develop a neuromuscular electrical stimulation-based anterior cruciate ligament stabilization system. Electrical feedback from an array of magnetic proximity sensors around the knee will cause contraction of either abdominal oblique muscle using repositionable electrodes, causing core rotation in the direction of knee rotation, effectively stabilizing the knee and preventing injury.

From Canyon: Here’s a graphic I made comparing a study from UMichigan of thigh position during the gait cycle using video motion tracking (red), to about 20 cycles I pulled from my data. Quite on point.

Canyon is making good progress on his inertial sensor.  In the video above you can see the live pitch data with the video of the runner.  The pitch is referring to the angle of the thigh, which will eventually be combined with other angles to form a full picture of motion.

Project BZ is now Anax.

Project Anax is a critical part of Project BZ development.  Following BZ testing, it was determined that a more accurate method of joint monitoring was necessary.  Bluetooth inertial sensors were considered for use in the system.  Current bluetooth inertial sensors on the market are bulky and quite expensive.  I designed a bluetooth inertial sensor that is slimmer, sleeker, and as low as 1% of the cost of the sensors that currently dominate the market.

Project BZ continues with treadmill testing!
