An inhalation device defines a receptacle for receiving an aerosol-forming substrate containing at least one vaporizable substance; an atomizer configured to generate an aerosol from the aerosol-forming substrate; a first sensor configured to generate a first signal or first data associated with a presence of at least one chemical substance in the generated aerosol; a second sensor configured to generate a second signal or second data associated with a further characteristic of the generated aerosol or of the aerosol-forming substrate or of the at least one vaporizable substance; and at least one controller configured to separately analyze both the first signal or first data and the second signal or second data to determine first and second analysis results, and configured to determine an operation mode of the inhalation device or to determine whether to alter an operation of the inhalation device based on both the first and second analysis results.

A system for compounding medications. The system includes one or more compounding devices, and a central computer system. The central computer system receives requests, at least some of which require the compounding of one or more medications, and pushes assignments of respective compounding tasks to the one or more compounding devices. The assignments are made in accordance with a set of rules designed to promote efficient use of compounding resources.

A device for preparation of infusion fluid including: a first portion including: a fluid conduit comprising electrically conductive material; electrical circuitry electrically connected to the fluid conduit; a second portion selectively couplable to the first portion and including: at least one sensor for sensing fluid within the fluid conduit; a power supply and/or connectivity to a power supply; wherein mechanical coupling of the first portion to the second portion electrically connects the electrical circuitry to the power supply and/or connectivity to the power supply.

An aerosol delivery device includes a chamber for receiving an article including an aerosolizable material for delivery by the aerosol delivery device, a transmitter, a receiver spaced apart from the transmitter, and a processor. The processor is configured to: cause the transmitter to transmit a first signal to the receiver at least partially through an article in the chamber in use, so that the receiver receives a second signal, wherein the second signal is the first signal altered by interaction with a signal altering component of the article, and determine article data from the second signal. An article includes an aerosolizable material; and a signal altering component. The signal altering component is configured to alter a first signal transmitted at least partially through the article into a second signal indicative of article data.

A system and method for determining the fill volume of a fluid chamber includes a fluid injector, at least one fluid chamber in fluid communication with the fluid injector, one or more sensors positioned relative to the at least one fluid chamber and configured to detect a position of a liquid-gas interface of the fluid contained in the at least one fluid chamber, and at least one processor in communication with the sensors and the fluid injector, and configured to: determine the position of the liquid-gas interface of the fluid, calculate the volume of fluid in the at least one fluid chamber based on the position of the liquid-gas interface, and at least one of: i) display the volume of the fluid; ii) enable the fluid injector to perform an action; and iii) disable the fluid injector from performing the action.

An apparatus and methods enhances the energy levels of a person, in particular the relating to guiding a person's breathing to enhance energy and health. The device is a breath guide device having an airway, breathflow guiding equipment, a control unit capable of communicating with a memory unit. The control unit is arranged to control the breathflow guiding equipment in dependence on data held in the memory unit. A mouthpiece suitable for placement at a user's mouth may be included. The breathflow guiding equipment includes an electronically operated valve for regulating the flow of breath through the airway.

A ventilation device for artificial ventilation, having: —a ventilation gas source; —a ventilation conducting assembly for conducting inspiratory ventilation gas from the ventilation gas source to a patient-side, proximal ventilation-gas outlet opening and for conducting expiratory ventilation gas away from a proximal ventilation-gas inlet opening; —a pressure-changing assembly for changing the pressure of the ventilation gas flowing in the ventilation conducting assembly; —a control device, which is designed to control the operation of the ventilation gas source and/or the operation of the pressure-changing assembly; —an evaluation device for processing sensor signals; and —an O2 sensor assembly for determining an O2 concentration value representing the oxygen concentration of the ventilation gas flowing in the ventilation conducting assembly, wherein the O2 sensor assembly outputs O2 sensor signals, which contain information regarding the O2 concentration value, to the evaluation device, and wherein the evaluation device is designed to determine, on the basis of the O2 sensor signals, an O2 change value representing a change in the O2 concentration value and, if the O2 change value satisfies a predefined condition, to infer degradation of the O2 sensor assembly and to output a signal.

Described herein are an interactive apparatus and methods for sensing and measuring real-time characteristic patterns of a subject's use of a dry powder inhalation system. The inhaler device can be used in a wireless communication mode to communicate with a display to assess the subject's usage of the inhalation system concurrently as the inhalation is performed and thus the subject's inhalation can be evaluated as well as the performance of the inhalation system. The system can also detect the identity of the medicament, its dosage, lot, expiration, etc. and the characteristics profile of a dry powder formulation emitted from the inhalation system in use.

A method includes receiving data associated with a sleep session of a user. The method also includes determining that the user is experiencing or has experienced an event based at least in part on the data. The method also includes causing pressurized air to be directed from a respiratory device to a multi-compartment bladder in response to determining that the user is experiencing or has experienced the event to aid in modifying a position of a head of the user.
