The Challenge:

Need to measure sleep patterns of senior citizens, chronically ill patients or patients suffering from sleep apnea to see how well they are sleeping through the night? In addition the following goals need to be met:

• Monitor weight to see if they are losing or gaining weight?
• Monitor movement to detect restlessness at night?
  • Did they wake up and get out of bed at night?
  • How many times did they toss and turn?
• Monitor weight distribution to detect if patient needs to be moved to avoid bed sore
• Monitor movement to see if patient is about to fall off from bed
• Export data into excel for plotting/charts and analysis.
