Abstract: A first set of data reflects usage of a resource based on readings from a metering device located at a first user's premises. A second set of data reflects usage of the resource at multiple other user premises. Comparison and usage indicators are generated based one the first and second sets of data. A comparison indicator is generated based on the first set of data and the second set of data. A usage indicator is generated based on the first set of data. The usage indicator reflects the usage of the resource at the first user's premises over a period of time and the comparison indicator reflects the same usage relative to the usage at the multiple user premises over the same period of time. The comparison indicator and the usage indicator are sent to a mobile device that displays the indicators.

Abstract: A dynamic optical filtration system and method effectively blocks bright light sources without impairing view of the remainder of the scene. A sensor measures light intensity and position so that selected cells of a shading matrix may interrupt the view of the bright light source by a receptor. A beamsplitter may be used so that the sensor may be located away from the receptor. The shading matrix may also be replaced by a digital micromirror device, which selectively sends image data to the receptor.
