ALEXANDRIA, Va., Dec. 1 -- Joseph Reghetti of Las Vegas, and Barry Kenneth Anspach of Centennial, Colo., have developed methods and apparatus for generating a data structure indicative of an alarm system circuit.
According to the U.S. Patent & Trademark Office: "A user of a computer aided design system graphically places fire alarm elements, such as smoke detectors, sirens, and sources on a drawing area.
After one or more of the elements are placed, the disclosed methods and apparatus automatically determine a series of electrical circuit connections between alarm source elements and alarm appliance elements. This determination may be based on circuit type compatibility as well as a number of connected segments between a particular alarm source and a particular alarm appliance."
The inventors were issued U.S. Patent No. 6,970,078 on Nov. 29.
The patent has been assigned to MEPCAD Inc., Las Vegas.
The original application was filed on Oct. 29, 2002, and is available at: http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=/netahtml/search-adv.htm&r=1044&f=G&l=50&d=PTXT&s1=ISYMD-20051129&p=21&OS=ISD/11/29/2005&RS=ISD/11/29/2005.
