Abstract: The sinkhole detector detects the formation of sinkholes in the immediate vicinity of the sinkhole detector and generates an alarm when a sinkhole is detected. The sinkhole detector is partially buried in the ground such that if a sinkhole forms underneath the sinkhole detector a weight is released into the void created by the sinkhole. The release of the weight initiates an alarm signal that a sinkhole has appeared. The sinkhole detector comprises a weight, a cable, a housing, and a control circuit.

Abstract: A method of displaying graphic user interface layouts including the steps of accessing a data repository storing an instruction set for constructing a graphic user interface layout through a network connection, rendering the graphic user interface layout associated with the instruction set and reducing the graphic user interface layout to a bitmap image. Once the graphics and text are laid out, the screen display is reduced to a bitmap image and associated with a uniform resource locator string. When a search query that retrieves the uniform resource locator string, the bitmap image and the uniform resource locator string are displayed to the end-user. As an alternative to displaying the actual text of the resource locator string, it may be embedded as an image hyperlink.
