Abstract: A system and processing techniques are provided for automatically detecting when an individual is under surveillance. At least one uniquely identifying characteristic associated with a vehicle or a person in proximity to the individual is detected as the individual moves about a geographic region, such as when the individual is traveling in a car. Positions in the geographic region where the uniquely identifying characteristics are collected and the times of these collections as the individual moves about the geographic region are also captured. Data is stored for detections of the uniquely identifying characteristics, times of detections and the positions where the uniquely identifying characteristics are detected as the individual moves about the geographic region.

Abstract: An electronic circuit for simultaneously erasing all the information stored in an electronic information storage device and entering a predetermined new pattern of information into the storage device comprises a plurality of bistable semiconductor cells with an additional transistor current-conducting region included on a predetermined side of each cell. The additional current-conducting regions in the cells along each word row are coupled to an additional word line which connects to a current switch for the row. At an appropriate pulse signal, the current switch activates to switch row current temporarily from the standard current-source word line, which conducts holding current to the row during normal operation, to the additional word line, thereby erasing the old data and entering the new information bits.
