Abstract: 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.

Abstract: The invention relates to a removable dental appliance comprising an appliance body configured to at least partially surround a plurality of teeth of a patient. The appliance body defines a shell configured to receive a tooth of the plurality of teeth in an initial position and a bendable flap integrally formed with the appliance body to tether the flap to the shell. The bendable flap defines a boundary region around the bendable flap and includes abridge, wherein the bridge extends between the body and the flap at or adjacent the boundary region. In one specific embodiment, the bridge is an arcuate member and includes a spring bellows. The bendable flap and the bridge are configured to apply a force to the tooth to cause movement of the tooth toward a desired position when the removable dental appliance is worn by the patient.

Abstract: An orthodontic palatal expander may include a first shell configured to receive at least one tooth of a first posterior segment of a dental arch of a patient; a second shell configured to receive at least one tooth of a second posterior segment of the dental arch; and a split beam connected between the first shell and the second shell. The split beam may include a first beam comprising a relatively high modulus material, a second beam comprising the high modulus material, and a region between the first beam and the second beam.

Abstract: 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.

Abstract: 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.
