Abstract: The jigsaw puzzle has a number of cubic playing pieces. On each of the six facets of each playing piece is displayed a segment of one of six different pictures. When the facets of one such picture all face upward and the cubes are correctly arranged side by side each other, the upwardly facing segments of the picture combine to display the complete picture. Similarly, when the cubes are arranged in turn so that the segments of the other five pictures are facing upwardly, the segments combined to display in turn the five other pictures. A magnetized sheet is provided on which the cubes are placed. The cubes are attracted to the sheet and remain stationary once they are placed on it so that it is unnecessary for the cubes to interlock to remain stationary when the puzzle is being worked on.

Abstract: Methods of detecting atypical patterns of usage of electricity, determined by monitoring consumption at the primary line, permit detection of grow-ops and unusual line losses due to defective service lines. A meter having a high resolution is connected to the primary line and the data collected is compared to known consumption patterns thus identifying a potential theft or a loss. Once an atypical pattern has been found, the heat signatures of transformers fed by the primary line are measured. An unusual heat signature alerts the utility to load test the secondary lines of each residence fed from the transformer and thus locate suspect residences which may be grow-ops or to locate a line loss due to defective service lines.
