Patent number: 11406850Abstract: Embodiments relate generally to methods and systems for refreshing filter media within a respirator and indicating end of service life for the filter media. A respirator may include a rollable filter media configured to be refreshed by rolling the filter media onto a roller. A rolling mechanism may rotate the roller, allowing for a fresh section of filter media to be placed in the air path of the respirator. The rolling mechanism may be controlled automatically by a motor and/or manually.Type: GrantFiled: March 8, 2017Date of Patent: August 9, 2022Assignee: Honeywell International Inc.Inventors: Durgam Gangadhar, Anitha Pulli, Praveen Kumar Palacharla, Anjaiah Tumu, PhaniKumar Kagithapu, Narasimha Jitendra

Patent number: 10843015Abstract: A system and method for completing fit tests on a respirator mask, and indicating end of service life for one or more elements of the respirator mask. The system includes an electronics module mounted on the interior of the face mask. The module includes a pressure sensor, and possibly other sensors, such as gas sensors, temperature sensors, and humidity sensors. The module may detect the pressure on the interior of the mask during fit tests to detect any leaks in the mask. The module may be used for positive and negative pressure fit tests. Additionally, the module may include one or more indicators (lights, sounds, vibrations) for alerting a user during a fit test. The module may also detect end of service life by analyzing the sensor data, and may indicate end of service life to the user.Type: GrantFiled: October 22, 2015Date of Patent: November 24, 2020Assignee: Honeywell International Inc.Inventors: Swapnil Gopal Patil, Karl B.

Patent number: 9959735Abstract: Embodiments relate generally to systems and methods for detecting harmful substances in the ambient air around a user, such as particulate matter and toxic gases, and communicating this information to the user and other interested parties. In certain areas, the ambient air in a city or area may sometimes contain harmful gases and/or particulates. People may be encouraged to wear and/or carry certain PPE devices, such as masks, to protect themselves from the harmful substances in the air. However, a user may not always know when they are breathing in a harmful substance and should be wearing a mask. Also, a method may comprise activating an alarm to user to when environment is polluted, and alerting the user when to wear the respiratory mask. Additionally, a system may provide information on where a user may be able to obtain a mask or other PPE, based on the detected harmful substance.Type: GrantFiled: April 21, 2017Date of Patent: May 1, 2018Assignee: Honeywell International Inc.Inventors: Swapnil Gopal Patil, Lakshma Reddy Dodda, Anjaiah Tumu, PhaniKumar Kagithapu, Veerender Sura
