Filed:

Jan 18, 2000

Appl. No.:

09/487385

Inventors:

Amer Wahid Akhras - Mahwah NJ
Matthew Lincoln Wagner - Buffalo NY

Assignee:

Praxair Technology, Inc. - Danbury CT

International Classification:

G06F 1518

US Classification:

706 21, 706 15

Abstract:

This invention is directed to a method for predicting the flammability of complex mixtures using critical variables of structural groups comprising training data from the critical variables of each structural groups, the critical variables comprising compositional and thermochemical data from each of the structural groups to produce a neural network model; testing the trained data from the neural network model; and validating the trained and tested data from the neural network to accurately predict the flammability limit of an analogous complex mixture having similar structural groups.

Abstract:

The present disclosure provides an inflatable product comprising a wall enclosing an air chamber. A plurality of main tension members and branch tension members are disposed within the air chamber. The main tension members have an upper edge and a lower edge. The branch tension members each include a first connection region and a second connection region each connected to the wall of the air chamber. The branch tension members each include a third connection region located between the first and second connection regions and connected to the upper edge or the lower edge of the main tension member.
