Disclosed are methods and a safety system of a structure for an air parameter based automatic purging of breathable air within the safety system. In accordance therewith, an air analysis device is coupled within the safety system along an air flow path of the breathable air from the source thereof. The safety system has a fixed piping system installed within the structure for supply of the breathable air across the safety system. A sensor associated with the air analysis device senses a parameter of the breathable air within the safety system. In response to an alert signal indicative of the sensed parameter of the breathable air being outside a predetermined threshold value, a valve and/or a vacuum pump within the safety system automatically purges the safety system of at least a portion of the breathable air.

Disclosed are a method, a device and a system of a sensor integrated safety system based computing platform. The computing platform is executed on a data processing device and integrated with a set of sensors associated with components of a safety system In accordance therewith, the data processing device collects a number of parameters of the components of the safety system and/or of access thereof through detection of the number of parameters via the set of sensors. The number of parameters includes one or more parameter(s) related to breathable air from a source within the safety system supplied thereacross via a fixed piping system implemented therein and/or access of the breathable air. The data processing device also monitors the safety system and/or one or more components thereof based on the collected number of parameters.

Disclosed are a method, a device and a system of sensor-based breathable air quality monitoring in a safety system of a structure. In accordance therewith, an air quality analyzer is coupled to a fixed piping system installed within the structure to facilitate delivery of breathable air from a source thereof. The air quality analyzer includes an air sequestration chamber in which a portion of the breathable air is segregated for analysis as an air sample, and one or more sensor(s) to sense one or more air quality parameter(s) from the air sample within the air sequestration chamber. An analysis module of the safety system performs analysis of the sensed one or more air quality parameter(s) based on coupling thereof to the air quality analyzer and transmits data associated with the analysis over a communication link.

Disclosed are methods and a safety system of a structure for an air/environmental parameter based automatic closing of a valve to isolate breathable air supplied to a level of the structure having the breathable air supplied thereto from a source. In accordance therewith, a parameter of an environment of the level of the structure and/or the breathable air supplied thereto is sensed using a sensor associated with one or more component(s) of the safety system. In response to the sensing, the one or more component(s) automatically closes the valve associated with control of the supply of the breathable air to the level to isolate the breathable air supplied to the level.

A disc filter frame comprising a base member and a lever, said base member including, adjacent a first end thereof, a breathing aperture and a connection arrangement configured to connect to a respiratory device, said breathing aperture and connection arrangement being aligned so as to define an airflow channel therebetween; said lever being hingedly connected by a hinge mechanism at its proximal end to said base at said first end and including a sealing member shaped and configured to cover said breathing aperture, the lever being biased in a first position in which a gap is defined between said sealing member and said breathing aperture, and selectively movable to a second position in which said sealing member seals said breathing aperture, the distal end of said lever being located and spaced apart from adjacent a second, opposing end of said base and configured to be manually pressed to move said sealing member from said first position to said second position.

There is provided a sensor including a housing, where the housing has an opening configured to receive a sensing element; an electric circuit operably connected to the housing, where the electric circuit is configured to detect at least one electrical characteristic across at least one pair of electrodes positioned on the sensing element; at least one gas-moving element in electrical communication with the electric circuit; and a reader in communication with the electric circuit, where the reader is configured to compare information about a gas volume external to the housing with information about a gas volume within the housing.

A system and method for prediction of the time to service components for a fleet of portable oxygen concentrators (POCs) is disclosed. Each of the POCs include a transmitter to transmit operational data. A network interface is configured to receive operational data from the POCs. A user database contains profiles of users associated with respective POCs. An analysis engine updates the profile of a user associated with a POC in the user database based on received operational data from the POC. The analysis engine determines a similar profile in the user database to the updated profile. The analysis engine predicts a service date for the component of the POC based on the similar profile and the updated profile.
