Abstract: A nasal device is provided to measure an aspect of gas flowing through a user's nose. The nasal device includes a body having a first interior side and a second, opposing interior side. The body forms a lumen between the first interior side and the second interior side through which the gas flows into and out of the user's nose. The nasal device further includes an emitter coupled to the first interior side and configured to emit emitted energy, a detector coupled to the second interior side and configured to receive detected energy, and a wireless transceiver coupled to the body and configured to transmit data corresponding to at least one of the emitted energy and the detected energy.

Abstract: A respiration monitor configured as a patching having adhesive on one side to allow adhesive attachment of the patch to a person. The patch includes a transmitter which generates a reference signal that is provided to a signal path. The signal path is configured to receive and conduct a transmitted reference signal such that the signal path has a length that increases when the person inhales and contracts when the person exhales. A receiver is configured to receive a received reference signal from the signal path. A controller is configured to control generation and transmission of the reference signal and processing the transmitted reference signal and the received reference signal to identify changes in the received reference signal due to transmission through the signal path as the signal path expands and contracts. This is done to generate respiration data that reflects respiration characteristics of the person.
