Title: Andrew McIntosh: Respirator Cartridge Gas-Sensing Innovation

Introduction

Andrew McIntosh is an inventor associated with Chicago, Illinois, and Honeywell International Inc. His patent work addresses how respirators can indicate when a cartridge has reached the end of its service life. The available information lists 1 patent associated with him.

Latest Patents

McIntosh’s listed patent is “Gas Sensing Drift Compensation Using Gas Self-Referencing for End of Service Life Indication for Respirators.” The invention describes systems and methods for estimating a respirator cartridge’s remaining service life by comparing gas levels measured at two or more sample points inside the cartridge. Sample streams can be directed to a gas sensor, with a valve controlling the flow between the streams and the sensor. This approach is intended to support end-of-service-life indication while accounting for sensor drift through gas self-referencing.

Career Highlights

The patent reflects work on respiratory protection technology, particularly the sensing and monitoring systems used to determine when a respirator cartridge should be replaced. McIntosh is associated with Honeywell International Inc., a company whose work includes safety and protective equipment.

Collaborations

The provided information identifies Christopher Scott Larsen and Peter Tobias as McIntosh’s coworkers. Their names are associated with his professional context, though the supplied details do not specify their roles in the patent.

Conclusion

Andrew McIntosh’s listed patent focuses on gas self-referencing to improve respirator cartridge service-life indication, contributing to the development of safety-focused sensing technology.
