Abstract: Respiratory biofeedback-based content selection and playback includes using data obtained using one or more sensors of a mobile device running a software application to produce a respiratory data stream of a user of the software application and select content to output to the user. The respiratory data stream represents various respiratory information of the user and is processed to determine a user state of the user. Certain content is selected based on the user state and based on a defined respiratory objective of a guided session being run using the software application. Initial content previously output to the user during the guided session may then be adjusted by outputting the selected content to the user. A change in the user state resulting from the outputting of the selected content may then be used to determine a progress of the user toward achieving the defined respiratory objective of the guided session.

Abstract: A dosage measurement system is adapted to receive a motion from a dosage injection mechanism disposed within a drug injection pen. The dosage measurement system includes a substrate, a sensing capacitor disposed on the substrate, and a lifting tab. The sensing capacitor includes a dielectric layer disposed between a base plate and an adjustable plate. The lifting tab is attached to the adjustable plate and positioned to engage an undulation pattern disposed on a component attached to the dosage injection mechanism. The lifting tab is adapted to physically change a separation distance between the adjustable plate and the base plate in a reciprocal manner in response to the motion of the dosage injection mechanism and engagement with the undulation pattern. A capacitance of the sensing capacitor changes in response to the engagement of the lifting tab with the undulation pattern and the motion of the dosage injection mechanism.
