A light fixture includes an array of light-emitting diode ('LED') light sources, a driver circuit that drives the array of LED light sources, and a controller. Controlling the light fixture includes receiving a first output color spectrum for the array of LED light sources that corresponds to a fixture color output spectrum, performing an optical modification of the fixture output color spectrum, determining, based on the optical modification, a compensation value to modify the first output color spectrum to a second output color spectrum that compensates for changes to the fixture output color spectrum resulting from the optical modification, generating, based on the compensation value, a first control signal to drive the array of LED light sources at the second output color spectrum, and controlling the driver circuit using the first control signal.

Color compensation for optical modification

A method for insulating a pier and beam foundation on a structure, wherein the pier and beam foundation includes at least one floor joist, at least one pier, at least one beam, a side skirt, flooring, and plumbing including at least one pipe, may include applying a synthetic underlayment to the at least one floor joist and to a bottom surface of the flooring; laying a radiant insulation board end-to-end across the at least one floor joist, over the synthetic underlayment, and along the side skirt; and applying a tape to adjacent radiant insulation boards to seal joints there between. The method may also include wrapping the at least one pipe with spray foam, a foam pipe insulator, and duct tape.

A method of surveying a venue includes scanning at least a portion of the venue using an unmanned aerial vehicle having at least one scanner, converting scan data gathered by the at least one scanner into three-dimensional location data, displaying the three-dimensional location data as a three-dimensional model, analyzing the three-dimensional model, and designating portions of the three-dimensional model with semantic mapping.

A method of controlling a plurality of light fixtures. The method includes determining first light outputs for each of the plurality of light fixtures. The method also includes determining a first spectrum of light reflected off of a surface. The method further includes determining a first difference between the first light outputs and desired light outputs for each of the plurality of light fixtures. The method also includes determining a second difference between the first spectrum of light reflected off of the surface and a desired spectrum of light reflected off of the surface. The method further includes calculating an updated output spectrum for the plurality of light fixtures based at least in part on the first difference and the second difference. The method also includes determining a second set of light source output values based at least in part on the updated output spectrum.

System and method for controlling a plurality of light fixture outputs

A method of controlling a plurality of light fixtures. The method includes detecting the light outputs of a plurality of light fixtures and detecting a reflection of light from a surface. The light outputs and the reflection of light are analyzed. Differences among the light outputs of the plurality of light fixtures are determined, and a difference between the reflection of light and a desired reflection of light is determined. New or updated values for output color, output brightness, and/or output spectra are determined for the plurality of light fixtures such that the light outputs of the light fixtures are consistent and correspond to a desired light output, and such that the reflection of light corresponds to the desired reflection of light. Each of the plurality of light fixtures is then driven using respective light source output values to produce the desired light outputs.

The vehicle pulled snow scraper system is an adjustable width snow blade having a pivotally attached blade in which the forward-backward tilt of the blade is adjusted via the winch. The forward-backward tilt function also may raise and lower the bottom edge of the blade in relation to the ground surface. The invention has a two piece hitch receiver bar having two different diameters of tubing, with an impact spring between the tubes to absorb impacts when the blade catches an immovable object. The outside edges of the blade assembly extend outward to greatly increase the width of the snow plow blade as desired by the user.
