A respiratory mask body defining a breathable air zone for a wearer and having a shut-off valve is provided. In an exemplary embodiment, the mask body includes one or more inlet ports configured to receive one or more breathing air source components. The shut-off valve is operable between a closed position and an open position, and when in a closed position the shut-off valve prevents fluid communication between the one or more inlet ports and the breathable air zone and the shut-off valve returns to an open position in the absence of an applied force.

A removable dental appliance may include an appliance body at least partially surrounding two or more teeth of a patient. The appliance body may include a first shell shaped to receive a first tooth; a second shell shaped to receive a second tooth; and at least one spring bellows that includes an arcuate displacement extending over and away from at least a portion of an interproximal region between the first tooth and the second tooth to join the first shell and the second shell. The spring bellows is configured to apply a force between the first shell and the second shell to cause movement of at least one of the first tooth and the second tooth toward a desired position when the removable dental appliance is worn by the patient.

A flexible hook hanger comprises an elongate sheet of pliable backing, an adhesive layer and a hook element. The backing comprises first and second ends, a first zone positioned adjacent the first end, a second zone positioned adjacent the second end and a central zone positioned between the first and second zones. The adhesive layer is disposed on one side of the backing. The hook element is connected to the central zone. In one embodiment, the pliable backing comprises microstructured tape, and the adhesive layer comprises a pressure sensitive adhesive composition comprising one or more hydrocarbon block copolymers, and a polar phenolic tackifier. In another embodiment, at least one of the first and second zones includes a peel arrestor. For example, the first zone and the second zone have a first width and a second width, respectively, and the central zone has a third width that is less than at least one of the first width and the second width.

Magneto-Mechanical Resonator Sensor with Mass Distribution Channel Some aspects of the present disclosure feature a sensing device (e.g. for temperature, moisture or detection of substances) comprising a magnetic bias layer, a resonator, a spacer, and an environmental change receptor. The spacer is disposed between the magnetic bias layer and the resonator. At least one of the resonator surfaces has a predefined channel. The environmental change receptor is disposed proximate to the predefined channel. In response to a change in environment, the environmental change receptor distributes along a part of the channel.

A securement device for securing a medical article is disclosed. The securement device comprises a base and a first securing portion comprising a strap that is movable between an open position and a closed position and a connector disposed on the base. The strap cooperates with the connector in the closed position to form an enclosure. The strap further comprises a curvilinear segment that projects inwardly into the enclosure in a convex orientation when the strap is in the closed position. Securement systems for securing medical articles and methods of securing at least a portion of a medical article to a patient are also provided.

Catheter securement device

Some aspects of the present disclosure feature a sensing device comprising a magnetic bias layer, a resonator, a spacer, and an environmental change receptor. The environmental change receptor is disposed on a surface of the resonator. The mass of the environmental change receptor is changed in response to a change in environment. The resonant frequency of the sensing device shifts in response to the mass change of the environmental change receptor.

Magneto-mechanical resonator sensor with pre-disposed mass

Some aspects of the present disclosure feature a sensing device comprising a magnetic bias layer, a resonator, a spacer, and a housing. The spacer includes an environmental change receptor. The thickness of the environmental change receptor rapidly increases in response to a change to an environment variable.

Magneto-mechanical resonator sensor with absorption material

Some aspects of the present disclosure feature a system for sensing a change in environment comprising a MMR sensor and a reader. The MMR sensor is configured to be disposed in the environment. The MMR sensor comprises a magnetic bias layer, a resonator, a spacer, and an environmental change receptor. The reader is configured to measure a frequency characteristic of the MMR sensor after the environmental variable changes and the change to the environmental variable is evaluated based on the frequency characteristic.

A structured abrasive article comprises a backing, and an abrasive layer disposed on and secured to the backing. The abrasive layer comprises shaped abrasive composites, each comprising abrasive particles dispersed in a binder. Each the shaped abrasive composites independently comprises: a base disposed on the backing; a plurality of walls extending away from the base, and a grinding surface not contacting the base. Adjacent walls share a common edge. Each wall independently forms a dihedral angle with the base of less than or equal to 90 degrees. The grinding surface has a plurality of: cusps, and facets that contact a recessed feature. At least a portion of the recessed feature is disposed closer to the base than each of the cusps. Each cusp is formed by an intersection of two of the walls and at least one of the facets. Use of the structured abrasive article to abrade a workpiece is also disclosed.
