DISPLAY WIDGETS FOR USE IN A MULTI-DISPLAY ENVIRONMENT
An apparatus for controlling a secondary monitor with widgets displayed on a primary monitor. A display device displays a graphical user interface having at least one region to display at least one widget. The widget receives input via the graphical user interface. A hardware processor coupled with the display device interprets the input received via the widget of the graphical user interface and generates one or more control signals to be sent to the secondary monitor to modify operation of the secondary monitor based on the input received via the widget.
An automated computer-controlled sampling system and related methods for collecting, processing, and analyzing agricultural samples for various chemical properties such as plant available nutrients. The sampling system allows multiple samples to be processed and analyzed for different analytes or chemical properties in a simultaneous concurrent or semi-concurrent manner. Advantageously, the system can process soil samples in the “as collected” condition without drying or grinding. The system generally includes a sample preparation sub-system which receives soil samples collected by a probe collection sub-system and produces a slurry (i.e. mixture of soil, vegetation, and/or manure and water), and a chemical analysis sub-system which processes the prepared slurry samples for quantifying multiple analytes and/or chemical properties of the sample. The sample preparation and chemical analysis sub-systems can be used to analyze soil, vegetation, and/or manure samples.
