## Customer Introduction

AlterG was a startup company designing an anti-gravity treadmill that provides air pressure to lift most of a person's weight off their feet, so they can exercise when injured or they can exercise longer.

## Problem/Goal

- *The unit was getting reset by static discharges created by the air blower.
  
  *The circuit seamlessly interfaces to motors and fans running on 220 VAC and delicate sensors measuring force and pressure.
- *The company lacked senior electrical engineering skills.  
  *  
  Isolate electrical issues to ensure reliable, consistent operation of the unit.*  
  *
- *The unit must meet medical requirements for electrical isolation, emissions, immunity, safety, and verification testing.
  
  *The anti-gravity treadmill was sold to professional teams and athletes, but the company wanted to expand its usage to appropriate medical and therapeutic applications. It had to be classified as a class II medical device and pass FDA requirements to do so.

## Solution

The company chose to partner with Voler Systems to leverage its vast expertise in electronic design and medical devices.

- Conducted tests to identify the source of the static discharge. The circuit was redesigned with optical isolation and improved shielding and grounding to eliminate the problem.
- Collaborated with the transformer supplier, sharing design information and creating a custom transformer that not only powered the entire device but also fulfilled the stringent requirements of medical isolation and leakage current.
- Prepared the design change requirements, ensuring they were ready for verification testing. Each requirement was defined with a clear pass or fail indication.** **

## Results & Benefits

- Eliminated the persistent static discharge issue with a single design change resulting in a significant enhancement to the overall performance and reliability of the treadmill.

- Achieved FDA approval as a medical device, validating its quality, safety, and market acceptance.

- Established a streamlined process for designing and evaluating the unit, facilitating manufacturing.

## Inspiration

Voler Systems' expertise in analog circuit design and deep understanding of the medical device approval process played a pivotal role in driving the project's success and was critical to the project's success.

*"Voler Systems consistently went above and beyond, delivering excellence in both their work and customer service. They were an invaluable partner in our journey to success."
