OverviewMonitor a patient outside of a hospital settingA tool for healthcare professionals to diagnose and

monitor a patient’s problems and progress over the long term

Assess daily activities such as lifting their foot, measuring distance traveled, room monitoring, etc. will be upgraded later by adding complex and costly sensors

Achieve objectives with three different groups: data acquisition, footwear and a walker

Operate on a $1000 budget shared between three groups

To measure forces in different areas of the foot

In depth analysis when combined with walker provides early diagnosis of hip and leg problems

Monitors progress in rehabilitation

Portable design makes analysis more convenient

Analysis-Data GatheredImplement force

sensors with accelerometer to assess the forces the foot experiences in a typical day

Differing forces in the front and back of the foot

BackgroundData acquisition systems are processes used to collect and

interpret information.The data acquisition process is integral to all design projects. Our job as Data Acquisition group is to interpret and present

the data collected by the motions sensors on the footwear and the walker in the form of graphs and tables that others can read and use.

IssuesWe are finding that it is

possible issues may arise when it comes to data transmission.

The Walker and Footwear groups have not decided how they want to transmit data from their sensors, so we will continue to communicate with and assist them with their choices.

LabViewOur group’s main tool is LabView.It is versatile and flexible enough to accomplish tasks

in many different engineering fields.Using this software we are able to take raw input

signals and translate them into graphs and other readable data.

Our Expectation By the end of the semester:

Each part of the system should work correctly We should be able to collect and analyze data We should have a working prototype.
