Abstract: A sterilization box for treating room air is described. The air drawn into the sterilization box is irradiated with UV radiation, such as is provided from UV LED chips. The air may be drawn into the sterilization box by under-pressure within the box created by fans at the exit ports of the box. The air may be drawn into a first chamber of the box where it is treated with one wavelength of UV radiation and then passed to a second chamber, where it is treated with a second wavelength of UV radiation. After the air is sterilized, it can be put back into the room or building in which the fixture is placed.

Abstract: System and method incorporating devices wirelessly connected to remote gateway locations or other devices. Remote gateway locations can be located on towers, buildings, silos, trees, utility poles, light poles or any other support structure capable of supporting the equipment used. A wired or wireless backhaul connects each remote gateway to a centralized headend gateway location via Ethernet, fiber, laser, or licensed or unlicensed microwave signals. Devices wirelessly connected to a remote gateway location device then act like a new remote gateway, redistributing signals to the surrounding area for additional CPEs to connect to that CPE. This continues over and over in a self-propagating manner, creating one or more network legs off the original remote gateway device.

Abstract: A grow light system is disclosed that can produce an adjustable combined emission spectrum, as is useful to growing plants of different types, or as is useful to adjusting the spectrum provided to a given plant as it grows. The grow light can include a sensor system to detect the height of plants it is illuminating, and can via a cable hoist adjust the height of the grow light to maintain an optimal distance between the plants and the grow light. The grow light system preferably includes a computer device with a graphical user interface useable to set a plant-to-grow light distance, and/or to select a combined emission spectrum for the grow light, which may occur by selecting a particular plant type, variety, or group. The system may include a library of optimal settings to configure the system to optimally grow each selected plant type, variety, or group.

Abstract: Various embodiments for analyzing flight data using predictive models are described herein. In various embodiments, a quadratic least squares model is applied to a matrix of time-series flight parameter data for a flight, thereby deriving a mathematical signature for each flight parameter of each flight in a set of data including a plurality of sensor readings corresponding to time-series flight parameters of a plurality of flights. The derived mathematical signatures are aggregated into a dataset. A similarity between each pair of flights within the plurality of flights is measured by calculating a distance metric between the mathematical signatures of each pair of flights within the dataset, and the measured similarities are combined with the dataset. A machine-learning algorithm is applied to the dataset, thereby identifying, without predefined thresholds, clusters of outliers within the dataset by using a unified distance matrix.
