A respirator that has a mask body and a nose foam, the mask body being adapted to fit over the nose and mouth of a person and having an interior surface that curves concave downward in the nose region of the mask body. The nose foam has first and second opposing major surfaces and a thickness T that extends from the first major surface to the second major surface. The first major surface of the nose foam is secured to the interior surface of the mask body in the nose region, and the opposing second major surface of the nose foam is available for making substantial contact with a person's nose when the mask body is placed on a person's face. At least the first major surface of the nose foam has a predefined downward concave curvature. A nose foam that is pre-shaped in this manner has less opportunity to become pinched or unnecessarily deformed before being placed on a wearer's face.

A flat fold filtering face piece respirator 10 that includes a mask body 12 and a harness 14. The mask body 12 includes a filtering structure 16 that contains a cover web 48, 50 and a filtration layer 52 that contains electrically-charged microfibers. The filtering structure 16 is folded over upon itself in a nose region 32 of the mask body 12 to be at least 1 centimeter or more wide and to extend across the upper perimeter of the mask body in a generally straight line when the respirator is in the folded condition. The filtering structure 16 has a deflection greater than about 0.5 millimeters and has a recoverability of at least 40% in the folded condition. A mask body having this construction is beneficial in that it does not need to use a nose foam to obtain a snug fit over the nose.

A valve cage device is adapted for use with a subsurface pump or the like. The valve cage includes a housing and an insert. The insert includes a cradle, a plurality of angled ribs, and a base. In one embodiment, the insert may also include an extended nose region. A ball and seat may be positioned in the valve cage. During pumping operations, the cradle retains the ball when the ball is unseated, thereby allowing fluid to pass freely through channels in the insert and around the ball. This eliminates violent action of the ball, thereby obviating a need for a hard liner to be included in the valve cage. A port in the cradle allows fluid to pass therethrough when the ball has been released from the cradle. The angular configuration of the ribs provides for a more laminar flow of fluid compared with prior art valve cages, thereby providing improved passage of fluid through the valve cage. The base may include an angled hook or lip that creates a tight seal, thereby preventing fluid from washing by during pumping operations. During pumping operations, when the ball is released from the cradle, it is guided by the insert and falls straight downward onto the seat, allowing for faster seating of the ball, and in turn, reducing pump stroke loss and providing for more efficient pumping. The valve cage may be configured for a traveling valve or standing valve portion of a subsurface pump or the like.

A flexible oro-nasal mask for mounting in a rigid shell attached to the helmet of aircrew at a fixed distance therefrom. The flexible oro-nasal mask incorporates an inspiratory and expiratory valve and the periphery of the mask is adapted to make a seal with the pilot's face. The oro-nasal mask includes an extendable structure which presses the periphery of the mask automatically towards the pilot's face to improve the seal therewith when gas at a pressure above that required for normal breathing is supplied to the mask. The extendable structure is configured so that when gas at a high pressure is supplied to the interior of the mask, the portion in the bottom region of the mask extends more than the portion in the upper region of the mask and the bottom of the mask is moved away from the wearer's face by a greater amount in the chin region than the nose region and the mask pivots upwardly automatically to compensate for the effects of G thereon. One embodiment of an extendable structure comprises an annular inwardly directed re-entrant recess formed in the wall of the mask adjacent the peripheral seal, the depth of said recess in the bottom half of the mask being greater than the depth in the top half thereof.

A patient interface packaging that includes an integrated sizing template. The packaging system includes a container having an inner chamber containing a patient interface device having a size contained within. The packaging further includes an outer exterior having an integral flap. The integral flap includes at least one opening therethrough forming a sizing template. The size of the opening corresponds to the size of the mask contained within the package so that the opening may be fitted to the nose region of a patient's to allow the user to determine an appropriate size patient interface device that matches his or her anatomical dimensions.

The invention discloses a mask wearing condition monitoring method based on face and posture recognition. The mask wearing condition monitoring method comprises the following steps of: step 1, acquiring a monitoring video; step 2, performing face detection on an image in the video data, and detecting whether a face exists in the image or not; step 3, if a face exists in the image, identifying theface and performing identity authentication, determining a target identity corresponding to the face, and if all target identities cannot be determined, returning to the step 1; step 4, performing mask detection on a detected face region, and detecting whether the target wears a mask or not and whether the target wears the mask correctly or not; step 5, if the target does not wear the mask or doesnot wear the mask correctly, transmitting a prompt to the target; and step 6, performing posture detection on the target, if a hand touches mouth and nose regions, sending a prompt to the target, andotherwise, continuing the posture detection. According to the mask wearing condition monitoring method, the condition of mask wearing can be automatically monitored and reminded, and the bad habit ofwearing the mask can be corrected.

The invention, which relates to the image processing technology, provides a color correction method for a color face image. With the provided method, the color correction precision is improved. Firstly, a face image is segmented into six target divided regions: an eye region, an ear region, a mouth region, a nose region, an eyebrow region, and a skin region by using a face five-sense-organ segmentation method; secondly, color blocks falling into all target divided region color ranges are selected from a color correction colour atla; thirdly, optimal color block sub sets of all target divided regions are selected by using a greedy searching algorithm, color correction models are established for all target divided regions at optimal color block sub sets of all target divided regions, and divided region color correction is carried out on a to-be-corrected color face image by using the established color correction models for all target divided regions. Therefore, the correction effect is closer to the practical face intrinsic color.

A baseball training apparatus occludes peripheral vision of each eye across the nose region of a baseball player by creating a visual divide that extends from and immediately adjacent to the nose along the central sagittal plane. In various embodiments, the visual divide is extendible, removable and replaceable, pivotal, and may incorporate scribes to vary shape or geometry. The visual divide may further be mounted from a pair of glasses without lenses, though other embodiments with and without lenses are contemplated. The eye divider is used to align or confirm alignment of a baseball player properly with the pitcher, to ensure that the batter has both eyes facing the pitcher.
