Filed:

Mar 31, 2006

Appl. No.:

11/394555

Inventors:

Douglas M. Williams - Del Mar CA, US

Assignee:

RF Check, Inc. - Del Mar CA

International Classification:

H04B 17/00

US Classification:

455 6711, 455423, 455424, 4554261, 4554221, 455520

Abstract:

Maintaining information about radio transmission sites in a computer accessible database. In one aspect this is a living database consisting of hundreds of thousands of wireless sites and their unique characteristics. The database includes energy transmissions information including site specific physical locations and utilization characteristics of the sites. The System can deliver MPE maps of radio frequency radiation and site specific safety programs to any worker visiting a wireless site in the United States. These maps (and site's specific safety programs) are updated on a daily basis. The System can be accessed via the Internet by registered users. The System creates and displays MPE maps and radiation pattern maps showing gradation power densities to identify exposure dangers.

Appl. No.:

12/023901

Inventors:

Douglas M. Williams - Del Mar CA, US

Assignee:

RF Check, Inc. - Del Mar CA

International Classification:

G06Q 10/00
G06Q 90/00

US Classification:

705 11, 705500

Abstract:

Computer based system which provides wireless site specific RF safety information and promotes protection of all concerned individuals from RF radiation. The System further informs contractors, workers, site owners, and FCC licensees bow to comply with federal, state and local RF safety standards and regulations. The system provides a method for managing and accommodating RF safety training and certification relating to the radio transmission sites. The system includes a database of transmission sites with corresponding antenna systems including maps of maximum permissible exposure limits, site physical layouts and camera images. The system provides a site specific RF safety summary sheet only to users having a predetermined training certification status. The system further includes recordation of training process, testing results, certification status, and delivery of RF safety summary sheets to users.

Appl. No.:

09/754996

Inventors:

Douglas Williams - Grand Rapids MI, US

International Classification:

F25D023/12
F25D017/02

US Classification:

062/259200, 062/434000

Inventors:

Douglas Williams - Del Mar CA, US

International Classification:

G06F017/60

US Classification:

705/001000

Abstract:

A business method of using information about the public telecommunications industry comprises establishing a computer accessible database storing energy transmissions information including site specific physical locations and utilization characteristics of wireless transmitting facilities that are currently operating in the public telecommunications industry, providing Internet access to the database information to registered users and preparing and downloading MPE overlay maps, EME dispersion simulation information and utilization characteristics reports from the database information of the site specific locations, upon request by the registered users. Site specific lock-out/tag-out orders and subsequent releases are obtained and issued for site specific management, upon request by the registered users.
