A filtering face mask 10 that has a mask body and a new exhalation valve 14. The mask body is adapted to fit at least over the nose and mouth of a person to help define an interior gas space when the mask is worn. The exhalation valve 14 permits fluid communication between the interior gas space and an exterior gas space. The exhalation valve 14 has a valve seat 20 and a flap 22. The valve seat 20 includes a resilient seal surface 24 and an orifice 30 through which exhaled air may pass to leave the interior gas space. The flap 22 is mounted to the valve seat 20 such that the flap 22 makes contact with the resilient seal surface 24 when the valve is in its closed position and such that the flap 22 can move away from the seal surface 24 in response to an exhalation to allow exhaled air to pass through the orifice 30 to ultimately enter the exterior gas space. A filtering face mask that utilizes an exhalation valve that has a resilient seal surface can enable the valve to open under substantially less pressure, which, in turn, may improve wearer comfort.

A mask for supplying gas under pressure to the nasal airway of an infant human includes a manifold for supplying air to an aperture in the mask. A shaped membrane structure formed from a thin walled membrane defines an enclosure for receiving at least the nares of an infant human nose and a generally trapezoidal aperture adapted to fit around the nasal area of the infant human. Part of the membrane around the aperture is sufficiently flexible to mould to the shape of the infant human's nasal area or is contoured to generally match the contours around that nasal area whilst the membrane structure itself has sufficient rigidity to support the weight of the backing plate without collapsing. The provision of a generally trapezoidal rather than the generally triangular apertures for fitting around the nares provides a substantially improved fit when the mask is used with infants. The moulding or contouring of the membrane structure around the aperture to match the shape of the infant's facial contours around the nasal area including the provision of a generally planar portion surrounding the aperture is also important in ensuring a comfortable fit and an effective seal. The mask is entirely formed from a flexible elastomeric material for reason of comfort and function.

The present invention proposes an odor measuring apparatus capable of determining the similarity of the odor of an unknown sample with high objectivity and performing measurements with sensitivity similar to that of the human nose. According to a mode of the invention, an m-dimensional space is created from detection signals of m pieces of odor sensors, and a standard odor vector S1 representing the result of measurement of a standard odor and another vector Sx representing the result of measurement of an unknown sample are drawn in the space.
