Within the solar energy industry, there is a general motto of "install it and forget it " for solar energy. This idea is largely derived from the research and reliability studies performed on the PV panels themselves but not the PV system as a whole (including inverters and other components). Other PV system components such as inverters contribute to a significant amount of power loss and the losses may vary based on different models of inverters. This technology relates to a method that can reduce measurement errors and achieve normalization among inverters used in PV systems in line with Class A of the updated IEC 61724-1 standard  With this method, the inverter-induced error can be reduced by up to 4.46%. The technology owner is looking for licensing partners to commercialize the test method.    

Prolonged sitting has been identified as one of the risk factors associated with lower back pain (LBP). Slumped sitting posture, commonly observed in daily activities, results in spine flexion and increases the erector spinae (ES) muscle activity. This in turn elevates the joint compressive forces and the intra-muscular pressure, disrupting ES muscle blood flow and muscle oxygenation. Association has been established between muscle blood flow and fatigue. The near infrared spectroscopy (NIRS) is commonly used to measure muscle oxygenation. This non-invasive technology is commonly used by researchers due to its high accuracy. It is based on the absorption of near infrared light between the oxygenated and non-oxygenated hemoglobin and myoglobin. However, this is not well applicable in clinical settings due to its high costs and bulkiness.
