A system and method for indicating the load condition of a vehicle having suspension components comprising:at least one of an inclinometer or an accelerometer mounted on at least one suspension component to measure the deflection angle of the suspension component; anda controller configured to use deflection angle and generate an output representative of the load condition of the vehicle. The process results in an improvement of the long-term power output of solar cells by maintaining optical transparency and reducing temperature increases arising from increased solar absorption in darkened coverglass assemblies. The process can be also used to control the inventory by shipping just in time any components required to produce target compositions, such as refinish tints used in automotive refinish paints. The computer system can also receive data descriptive of details of a financial transaction, wherein the details include an indication of at least one geopolitical area associated with the financial transaction. A sensor arrangement includes a planar optical waveguide, a light source, a sensor, an application unit for applying an analyte on top of the planar waveguide and a processor connected to the sensor.
