Abstract:
Respiration and heart rate are monitored using a fluid-filled bladder (12), where the bladder pressure is measured (16) and processed to identify minute pressure variations corresponding to the respiration and heart rate of a subject that is directly or indirectly exerting a load on the bladder (12). The respiration rate is identified by band-pass filtering the measured pressure to isolate or extract a pressure component in range of 0.15-0.5Hz (36), and the heart rate is identified by band-pass filtering the measured pressure to isolate or extract a pressure component in the range of 2-7 Hz (24). The extracted pressure components are preferably converted to a digital format and tabulated for comparison with specified thresholds to identify abnormalities and/or anomalies (30).
Abstract:
Disclosed is a method for direct application of a catalyst to a substrate for treatment of atmospheric pollution including ozone. The method includes applying a catalytic metal to a substrate utilizing a thermal spray process. The process can be utilized to apply a base metal such as copper to a substrate and the base metal becomes the catalytically active oxide during and following application to the substrate. This system replaces a multi-step process within a single step process to provide a catalytically active surface that can be utilized to reduce ground level ozone and other atmospheric pollutants.
