Abstract: Disclosed are methods and systems of reversible metal electrodeposition (RME) devices with applications in dynamic smart windows. Embodiments use a RME device that includes two transparent substrates that sandwich a working electrode, counter electrode, and an electrolyte solution. Embodiments apply a pulsed voltage to the RME device that causes electrochemical deposition of metal ions from the electrolyte solution to create a metallic film on the working electrode. The metallic film results in reduced light transmittance of the RME device.

Abstract: An efficient scalable networkable grow light system ensures that a DLI suitable for optimal plant growth without causing heat stress is met by selectively illuminating lighting elements of determined wavelengths, and adjusting intensity of the lighting elements, and adjusting the height of an assembly containing the lighting elements, if sensed ambient light is inadequate to meet the DLI. A hoist adjusts height to provide full illumination without causing heat stress, while reducing inefficiency due to excessive distance. If sensed ambient lighting is sufficient to meet the DLI, supplemental lighting is not activated.

Abstract: The disclosed process and system are used for the denitrification of wastewater. The system comprises: an influent concentration analyzer for measuring an influent dissolved oxygen concentration, an influent nitrate concentration, and an influent nitrite concentration; and a feed chemical controller for providing a feed chemical at a controlled rate. The feed chemical controller is responsive to one or more output signals provided by an automated control loop that accepts input signals from the influent concentration analyzer, which input signals relate to at least two of the influent nitrate concentration, the influent nitrite concentration, and the influent dissolved oxygen concentration.

Abstract: A process and system for denitrification of wastewater. The process includes the steps of measuring an influent flow rate, measuring influent concentrations of nitrates, nitrites, and dissolved oxygen in the wastewater, and using the influent concentrations to determine a nominal amount of methanol to be provided for denitrification. The invention also contemplates the measurement of effluent concentrations of nitrates and nitrites (i.e., NOx), and optionally using the effluent concentrations to adjust the nominal amount of methanol being provided.

Abstract: An optical imaging system having an optical source located between the object being imaged and the sensor is provided. Such positioning of the source enables provision of compact optical imaging systems. In particular, such systems can have image widths significantly larger than the object to sensor separation. The arrangement of source, imaging assembly and sensor is such that an image of the source is not formed at the sensor. Therefore, the effect of this source positioning on the image of the object at the sensor is a reduction of intensity, as opposed to more objectionable imaging artifacts, such as spurious shadows and/or bright spots. Thus compact optical imaging systems having good image quality are provided, which enables high-fidelity imaging of object to sensor for a wide variety of applications.
