Described are systems and methods for compensating long term sensitivity drift of catalytic type electrochemical gas sensors used in systems for delivering therapeutic nitric oxide (NO) gas to a patient by compensating for drift that may be specific to the sensors atypical use in systems for delivering therapeutic nitric oxide gas to a patient. In at least some instances, the long term sensitivity drift of catalytic type electrochemical gas sensors can be addressed using calibration schedules, which can factor in the absolute change in set dose of NO being delivered to the patient that can drive one or more baseline calibrations. The calibration schedules can be used reduce the amount of times the sensor goes offline. Systems and methods described may factor in in actions occurring at the delivery system and/or aspects of the surrounding environment, prior to performing a baseline calibration, and may postpone the calibration and/or rejected using the sensor's output for the calibration.

Assembly having a fluid product dispenser and an unlocking device. The assembly has a fluid product dispenser (D) having a movable member (F) and a locking system (L) that is switchable between a locking position, in which the movable member (F) is locked and a release position, in which the movable member (F) is unlocked; and an unlocking device (K), separate from the fluid product dispenser (D), that is able to switch the locking system (L) between the locking position and the release position, this unlocking device (K) being an eddy-current-based contactless and remote unlocking device.

The present disclosure provides system and methods for pulmonary health using one or more inhalation devices. In one aspect, the air inhalation devices each comprise one or more sensors configured to capture pulmonary health data for a patient. Using this data, air analytics may be generated pertaining to individualized patient health, general health for people living within a particular geographical location, air quality for a particular geographical region, operational parameters of the inhalation devices, and/or the like. The air analytics may be output, for example, for display on a user device, such as a patient user device, a health care provider user device, and/or an admintrator user device.

The invention relates to a personal ultrasonic atomizer device 10, which includes a cartridge 12 having a reservoir 26 for holding a liquid to be atomized, which is interchangeable prior to complete discharging of the reservoir 26 and includes an anti-tamper and anti-counterfeiting safeguard, a sonication chamber 14, placed in fluid communication with the reservoir 26, and for cavitating a liquid placed in contact with a piezoelectric oscillation piece 112; such that vape and/or mist is generated without combustion and/or heating of the liquid, where the device 10 includes a liquid retention means 76 for allowing use of the device in any orientation, and where the device is controllable by an external electronic device.

An electronic cigarette vaporiser is not dis-assembled for filling with e-liquid, but is instead filled from a user-replaceable e-liquid cartridge. The vaporiser includes a front section comprising a wick and heating assembly but no e-liquid cartridge, the front section being removably fitted to a body of the vaporiser to enable a replacement front section to be used once the original wick or heating element starts to degrade, that replacement front section being supplied to the end-user with no e-liquid in it.

An electronic cigarette vaporiser that includes a heating element and further includes or co-operates with an electronics module that (i) detects characteristics of the delivery of power, current or voltage to the heating element and (ii) determines if those characteristics are associated with degradation of the heating element. A characteristic that is associated with degradation of the heating element is an increase or other change in the heating element resistance. The heating element resistance can be established by the electronics module sending a test current through the heating element that is sufficient to enable a measurement of resistance to be made.

An electronic cigarette vaporiser that includes a heating element and further includes or co-operates with an electronics module that (i) detects characteristics of the resistance of the heating element and (ii) uses an inference of temperature derived from that resistance as a control input. The temperature of the heating element may be inferred from data stored in the electronics module that has been empirically obtained for a specific heating element design. The electronics module controls the power delivered to the heating element to ensure that it is no higher than approximately 130 C., plus an error tolerance.
