Memory aiding device

A memory aiding device comprising:

• a transparent substrate, location designating means comprising at least one row of a plurality of first location designating symbols printed on the substrate, and at least one column of a plurality of second location designating symbols printed on the substrate, at least one of the second location designating symbols effective in combination with at least one of the first location designating symbols for designating corresponding locations on the substrate so that a user definable location is designated by one of the first location designating symbols and one of the second location designating symbols, a plurality of groups of sequence representing elements printed on the substrate for representing a predetermined sequence comprising sequence elements selected from a predetermined set of potential elements, and locatable at said corresponding locations by the location designating means;
• and recording means comprising a sheet member adapted to record marks, each of said marks being addressable by one of said sequence representing elements so as to be readable as one of the sequence elements;
• whereby the transparent substrate is placable over the sheet member and the marks are perceivable so as to read the predetermined sequence so that the desired sequence is retrievable by disposing the recording means depending on the user definable location.

A memory aiding device for aiding in remembering a predetermined personal identification number, comprising:

• a substrate;
• sequence representing integers predisposed on the substrate in rows and columns for representing a personal identification number, each respective sequence representing integer being printed at a respective column and row intersection;
• location designating means for designating a plurality of locations, each location being an intersection of a row and a column and designating a set of sequence representing integers;
• recording means for recording a set of marks, each mark indicating a respective numeral of the personal identification number represented by a corresponding sequence representing integer, the recording means disposable relative to the substrate depending on the location so that the personal identification number represented by the corresponding sequence representing integers is perceivable by perceiving the marks.
