Abstract
A covering creates an air channel around a face of an entity wearing the covering. An actuable inlet includes a first conditioner. The actuable inlet regulates fluid exchange between the air channel and an outside environment. An actuable outlet includes a second conditioner. The actuable outlet regulates fluid exchange between the air channel and an outside environment. An air pressure within the air channel can be maintained at a specified level.
Claims23
A mask comprising:
- a covering formed to create an air channel around a face of an entity wearing the covering;
- an actuable inlet comprising a first conditioner, the actuable inlet regulating fluid exchange between the air channel and an outside environment;
- and
- an actuable outlet comprising a second conditioner, the actuable outlet regulating fluid exchange between the air channel and an outside environment.
1 more element
A method comprising:
- receiving filtered air into an air channel defined by a covering and a face of an entity wearing the covering;
- maintaining a pressure of the filtered air within the air channel;
- and
- expelling filtered air from the air channel.
1 more element
A system comprising:
- a covering partially defining an air channel in conjunction with a face of an entity wearing the covering;
- an actuable inlet comprising a first conditioner, the actuable inlet regulating fluid exchange between the air channel and an outside environment;
- an actuable outlet comprising a second conditioner, the actuable outlet regulating fluid exchange between the air channel and an outside environment;
- a pressure sensor arranged such that the pressure sensor senses a pressure within the air channel, the pressure sensor configured to produce a pressure stream indicative of a pressure within the air channel;
- a controller configured to:
- receive the pressure stream from the pressure sensor;
- and
- maintain a set pressure within the air channel responsive to the pressure stream received from the pressure sensor;
- and
- a power supply coupled to the controller.
