  • Publication number: 20070011738
    Abstract: In a matrix of password characters organized into rows and columns, the characters being selectively combinable to form passwords, the matrix having a plurality of column indices identifying respective columns of the matrix and a plurality of row indices identifying respective rows of the matrix, a method for remembering passwords includes selecting a first password from among the password characters and identifying an anchor character of the first password by its corresponding row and column index. The method also includes determining the anchor character's matrix location relationship with other characters of the first password. The method further includes retrieving the desired password from the matrix by locating the anchor character according to its corresponding row and column index and by using the anchor character's matrix location relationship with the other characters of the first password so that knowledge of respective matrix locations of the other characters of the first password is not required.

  • Patent number: 4796997
    Abstract: A method and system for high-speed, 3-D imaging of an object at a vision station including a flying spot laser scanner, a dynamically configurable spatial filter and a diffuser for spatial averaging, are used in conjunction with a variable transmission filter in an optical depth sensing system. The reflected laser signal received by the sensing system is first spatially filtered and averaged and then split into first and second beams which are imaged onto a pair of highly sensitive photodetectors which introduce capability for high-speed, 3-D sensing under low light level conditions. The first beam passes through a variable transmission filter which is used to encode position which, in turn, is proportional to the height of the object. The second or reference split beam is provided to compensate for changes in the reflectance of the object and the power of the laser scanner.
