Patent Overview — US7407029B2

Title: "Weight measuring systems and methods for vehicles"

Patent number / application: US7407029B2; application US10/895,121.

Inventors: David S. Breed, Wilbur E. DuVall, Jeffrey L. Morin.

Assignee/original assignee: Original assignee Automotive Technologies International Inc.; current assignee listed as American Vehicular Sciences LLC.

Key dates (as listed, and characterized in the source as assumptions): Priority date 1992-05-05 (claimed from US07/878,517); filing date 2004-07-21; publication of US20050017488A1 on 2005-01-27; patent granted/publication of US7407029B2 on 2008-08-05. Status: Expired – Fee Related, with adjusted expiration 2013-01-26.

Purpose and plain-language scope: Based on the supplied text, the patent relates to measuring the weight of a vehicle occupant and using that measurement to control a vehicle component (for example, an occupant restraint such as an airbag). The prior-art keywords supplied ("vehicle," "seat," "occupant," "adjustment," "bladder") indicate a seat-based occupant sensing approach. The patent is linked through numerous continuation/priority references to earlier Automotive Technologies International filings; the source lists many related patents, but the excerpt does not reproduce the claims, abstract, or detailed description.
