Patent ID: 7785257

Claim:
A non-invasive system for assessing physiological characteristics of a subject, said system comprising: a network of sensors configured to provide electronic output signals indicative of at least one sensed condition, said network including at least one passive sensor selected from the group consisting of vibration, temperature, carbon dioxide, humidity, electromagnetic and light sensors, and wherein said network of sensors further comprises a movable support including at least one sensor of the network of sensors; data acquisition circuitry for collecting the electronic signals output from said network of sensors; a processor configured to process the electronic signals, said processor including an amplifier configured to amplify at least one of the electronic signals, and first and second filters configured to receive the amplified electronic signals to produce two processed electronic signals, wherein said first filter includes a band pass filter and said second filter includes a low pass filter and a high pass filter, and wherein said first filter outputs a first signal corresponding to a respiratory rate on a breath-by-breath basis of the subject and said second filter outputs a second signal corresponding to a heart rate on a beat-by-beat basis of the subject; and an output device for outputting the processed signals into human-readable data indicative of at least one condition of a subject, wherein the human-readable data comprises a subject movement percentage.
