Home Health Care – Bringing Together Stakeholders

by Mr. Walt Maclay September 2013 Home healthcare is a huge market. The demand is growing. Investors, executives, and technologists all have ideas for solutions. The key to moving things forward is to bring all of these stakeholders together to look at their issues and concerns. Healthcare providers are worried that they're not going to [...]

Agile Product Development for Hardware

Agile product development techniques are transforming the way we develop software. But many people ask  "Can use agile product development for hardware?" We say "yes!" The Annuvia project was broken into four phases or sprints, of about one month each, to mitigate risk and cost: Sprint 1. Feasibility: A high level technical assessment was preformed, [...]

Feasibility Study Aids Business Decision

One task we often help clients with is exploring the feasibility of developing an idea into a product. Sometimes it is not clear that an idea can be implemented, or it is not clear how to implement it. A feasibility stage is a short investigation to determine how the design should best be done. We [...]

Motion Control Projects

Today, motion control has moved well beyond its traditional manufacturing industry. Medical devices, automotive, robotics and personal tools like smartphones and tablets benefit from the advancement of low cost, low power, and miniaturization of motion control. Motion Control in a Rehabilitation Device Voler developed this rehabilitation device for a startup who needed it designed and [...]

Voler Helps Out With Legacy Test Equipment

Voler was recently approached by a large medical device company that relied on test equipment that had been designed several years earlier by a firm that was no longer available. They ask Voler for help because for the last two years the equipment would periodically fail calibration and was providing inconsistent results. They had done [...]

Sensor Calibration Verifies Accuracy

FDA regulations for medical devices require manufacturers to develop and monitor production practices to ensure that the end device conforms to its specifications. A calibration program is a major part of this quality system to verify the accuracy and precision of measurements. Walt describes the techniques, tools, and equipment used to calibrate a disposable medical device.

Medical devices that rely on one or more embedded sensors not only need testing, but also sensor calibration. Digital circuits can be subject to pass/fail testing. However, sensors require precise testing or calibration to be accurate. Calibration ensures that different individual devices give the same result. Sensors needing calibration include temperature, pressure, acceleration, strain, and displacement.

A Fun & Interesting Project: Anti-Gravity Treadmill

Voler Systems provided two broad services to AlterG: debug and re-design of the main controller board and providing guidance and advice on how to get FDA approval to enter the medical market.

During the development process AlterG was having difficulty with static electricity causing system resets. Voler Systems was quickly able to solve the problem. By optically isolating the control buttons and providing enhanced shielding and grounding, we eliminated the failures because any static discharge would not couple into the board where the microprocessor was located. We provided the controller circuit board design and tested working prototype boards.

Fuel Leak Detection

An aging system triggered system engineers to search for an updated leak monitoring system for fuel storage tanks at Vandenberg AFB. The system engineers needed to replace the equipment that was obsolete and expensive to maintain. Voler was chosen to design, manufacture and install a new reliable system.

Prototype Catheter Measures Heart Muscle

Voler developed a circuit to measure the impedance of tissue inside the heart to determine which part of the tissue is infarcted (dead) for use in a prototype cardiac catheter. We worked with a medical device start-up to implement an innovative method to reliably detect the minute differences between healthy and infarcted heart tissue.
