US Patent:

6035299, Mar 7, 2000

Filed:

Aug 26, 1997

Appl. No.:

8/920119

Inventors:

Kerry M. White - Rancho Palos Verdes CA

Assignee:

International Classification:

G06F 1730

US Classification:

707101

Abstract:

A four-byte data structure for representing alphanumeric or numeric house numbers (addresses) for use in a mapping system. The data structure has the same field size as that used for representing house numbers with numeric characters. One bit of the data structure is used to determine the presence of a non-numeric character in the house number. If the bit stream defined by bit positions 30-28 is either "000" or "100" or 101" or "110" or "111", then fourteen bits represent the numeric portion preceding the alphabetic character, ten bits represent the numeric portion succeeding the alphabetic character, two bits represent leading zeroes preceding any alphabetic and numeric characters and two bits represent leading zeroes disposed after an alphabetic character and before a numeric character succeeding the alphabetic character. If the bit stream defined by bit positions 30-28 is "001", then one bit identifies whether the first character of a house number is numeric or non-numeric, thirteen bits identify the alphabetic character used in a house number, ten bits represent house numbers larger than 999 or represent characters other than the alphabetic characters, ten bits represent the numeric portion of a house number and two bits represent leading zeroes.

Abstract:

A navigation system user interface identifies and displays a list of all addresses which contain address components in conformity with the user provided "city name", "street base name" and "house number" and prompts the user to choose an address from the list thus provided. Alternatively, the interface generates a list of all the city names which contain valid addresses in conformity with the user provided "street base name" and "house number". The system, subsequently, displays a list of all possible addresses with components matching those entered/selected by the user and prompts the user to select an address from the list thus provided.
