Abstract: The invention provides a system and method for analyzing the performance of an irradiance sensor of a photovoltaic system. More specifically, a remote calibration system may receive irradiance data from an irradiance sensor of a PV system. The remote calibration system may then filter the irradiance data using one or more of a threshold filter, a curve fit filter, and a correlation filter. The filtered irradiance data is then compared to an estimated irradiance to generate an irradiance weighted average which may be used to adjust subsequent irradiance data provided by the irradiance sensor. A report system can be adjusted with the irradiance weighted average to prevent generation of a report for the irradiance sensor.

Mistaken fault conditions causing false alarms are corrected by use of current weather conditions and performance data to adjust fault detection algorithms and control features.

Abstract: The invention provides a system and method for analyzing and classifying the losses of a photovoltaic array. The system and method compares expected power output and to actual power output and can determine a photovoltaic string, combiner, or inverter is generating less power than expected due to at least one of snow cover, soiling, and inverter clipping. The system and method can then determine an amount of power lost during a period of time the photovoltaic string, combiner, or inverter is experiencing snow cover, soiling, or inverter clipping and determine a value of the amount of power lost during the period of time. Various user interfaces enable a user to view one or more reasons why a PV string, combiner or inverter is generating less power than expected and the value of the amount of power lost.

Abstract: A system and method of the invention adjusts an existing system model of a PV system to provide better information regarding projected performance of the PV system. The resulting model enables a user to more accurately compare actual versus expected performance, thereby quantifying performance degradation due to soiling, aging and component failures while also verifying the design assumptions. A method of the invention includes selecting days of historical data that will result in the highest quality results (e.g., high energy output, minimal clouds); determining key metrics and relationships between measured data and site characteristics to identify how to optimize model parameters; running simulations of the model over the key days to determine the best value for each model parameter that results in the closest match between the model and measured system output; and conducting iterations of the simulations to adjust various model parameters.

Abstract: A system is provided for creating and deploying script for web-based applications. The user can enter and edit the contents of a script package via a web application. During development, the script package may be sent to the server to be compiled and checked for errors. A simulated run-time environment can be generated on the server that can execute the script under a set of predefined conditions. The simulated run-time environment can allow the script to be tested before deployment. The results of the compile and execution tasks are sent back to the client so that the user can debug and perfect the script. The script package may then be stored in a database for continued development and/or editing and eventual deployment to a web server.

Abstract: A method for selecting and ordering photographic prints from a remote location that is apart from a lab. A roll of exposed film may be processed to produce film images of the images on the roll, which may be scanned to create a digital image file. The digital image file may be used to create a positive high-resolution digital image and/or a corresponding positive low-resolution digital image. A lab digital image file is created, including digital image data related to the low-resolution digital images and embedded lab meta data. At the remote location the lab digital image file is manipulated to display the digital images. One of the digital images at the remote location may be selected, along with order parameters. A studio digital image file is created, including the digital image data, the embedded lab meta data and embedded order meta data. A photographic print may then be created using the lab digital image file or the corresponding film image.

Abstract: A digital image processing system digitizes and stores photographic film images in their captured orientation on film, in order to obviate the need to physically rotate the film scanner relative to the film for vertical images, thereby significantly reducing the complexity and cost of the scanner. Instead, each stored image file has an associated presentation control file, which contains orientation and aspect ratio information, so that the image playback device will know how each image has been stored on the digital image database, such as a compact disc. When the disc is inserted into a playback device for driving an output display such as a color TV monitor, the playback device is readily able to decode the playback control information in the course of reading out the digitized image, so that the image will be displayed in an upright orientation and at the correct aspect ratio for the display.

Abstract: A multiple printhead thermal printer has a receiver and a print drum supporting the receiver as dye is thermally transferred to the receiver during printing. Electronic circuitry controls registration of the receiver during printing so that the color separations are aligned to produce a clear, crisp image. This registration is achieved by introducing line delays to receive the image data prior to the image data reaching the modulators which process the image data for the second and third printheads. The position of the image produced by a thermal printhead along the print direction is determined by when data is sent to the printhead. Delaying the printing of a line by some fraction of a line time proportionally repositions the print line by a fraction of a line.
