Latest Patents

Hewitt's latest patents include an "Optical sensor device having variable optical path length." This invention features an adjustable optical path length (OPL) that can be utilized in conjunction with a flow cell for ultraviolet (UV) absorbance measurements. The design incorporates optical windows installed in cylindrical window holders, which are secured by window retainers. The distance between the optical windows defines the OPL, which can be adjusted by rotating the window holder. This allows for precise control over the optical path length, enhancing measurement accuracy.

Another significant patent is the "System and method for measurement and control of suspended solids in a fluid." This system includes a sensor with a measurement chamber and a piston, along with a diverter valve that manages the introduction of sample fluid. The measurement cycle involves compressing the sample fluid and transmitting light across it to determine the concentration of suspended solids. This measurement is crucial for controlling the introduction of polymers into fluid sources, demonstrating the practical applications of his inventions.
