Health Spa Steam Chamber

Health Spa Steam Chamber

Developed the control panel and user interface for an innovative Spa Steam Chamber that provides oxygenated hydrotherapy for improving individual health and wellbeing.

The Client

RightHand's client is a pioneer in the development of oxygenated hydrotherapy systems and oxygen based products. They believe that the quality of health and vitality is closely linked to the quality of the air we breathe and the water we drink, and provide solutions that increase an individual's oxygenation and hydration, detoxifying using water, ozone and oxygen.

The Need

The client was seeking improved software efficiency as well as new features to their signature product, a deluxe steam chamber - a spa-like enclosure built for one. While comfortably sitting in the highly engineered enclosure with your head on the outside, your body is immersed in a cascade of flowing ultra-pure oxygenated water.

The RightHand Solution

The spa operations were run by a PLC controlling pumps, heaters, and a monitoring system. The user interface was in a separate box and included a Windows CE based controller with a touch panel interface.

The first prototypes of the unit used a single thread software architecture handling all spa operations. RightHand Technology engineers immediately improved performance by introducing a more efficient multithreading architecture. They designed separate threads for handling the PLC Polling and User Interface Polling. This improved the speed of operations and the user response time significantly.

The User Interface was redesigned, and additional PLC operation modifications were added to the system. Additionally, protection against cell phone interference was added during the second phase of this project. One interesting feature requirement was to ensure that the aerobic spa starts functioning only when the heart rate is within a permissible range for the given age of an individual. By using a heart rate monitor sensor and colorful GUI, the button changes color when the heart rate is in the danger zone and the machine function and temperature is adjusted.

The final phase was to add features for field maintenance. This phase included providing a way for the client to remotely monitor usage and supplies, and check on the correct functioning of the PLC hardware modules.

The Results

Overall, the entire project benefited by a team adhering to source control and well-defined software process. Improved documentation will ease future modifications.
