A drive mechanism of a drug delivery device is presented having, a piston rod to operably engage with a piston of a cartridge containing a medicament, a first functional component and a second functional component whose position or orientation relative to each other is unambiguously correlated to a predefined axial position of the piston rod, wherein the first and/or the second functional component comprise at least one engaging portion to inseparably and to adhesively engage the first and the second functional component with each other for rendering the drive mechanism inoperable when the predefined axial position of the piston rod has been reached.

A fluid ejection device includes a fluid ejection unit that ejects a fluid, an ejection control unit that receives a fluid ejection command input, and controls the ejection of the fluid from the fluid ejection unit, a fluid container that accommodates the fluid to be supplied to the fluid ejection unit; and a supply control unit that controls the supply of the fluid from the fluid container to the fluid ejection unit, and determines whether the fluid can be supplied to the fluid ejection unit from the fluid container. When the supply control unit determines that the fluid cannot be supplied even after the ejection command input is received, and then a predetermined amount of time has elapsed, the ejection control unit reports a fault, and prohibits the fluid ejection unit from ejecting the fluid until the ejection command input is canceled.

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.

A control body and cartridge that are coupleable with one another to form an aerosol delivery device are provided. The control body comprises a control component and an RFID reader contained within at least one housing. The cartridge comprises at least one heating element and an RFID tag contained within at least one housing. The RFID reader of the control body is coupled to the control component of the control body and configured to communicate with the RFID tag of the cartridge upon coupling of the control body with the cartridge. The control component of the control body is configured to authorize the cartridge for use with the control body based at least in part on communication between the RFID reader and the RFID tag.

A method of providing a vaping policy alert by a mobile communications device includes receiving, at the mobile communications device, mobile network data from a base station; extracting a country code for the location of the mobile communications device from the received mobile network data; obtaining vaping policy alert data responsive to the obtained country code; and displaying the vaping policy alert data.

Disclosed is a nebulizer having attached housing, which is attached in a way that permits removal, which housing holds containers of liquid medication for dispensing via nebulization, which nebulizer is constructed to allow containers holding the medication to be used and held within the housing provided that such containers match or conform to the certain mechanical requirements of the nebulizer and housing.

A case for an electronic cigarette vaporiser, the case including an automatic lifting mechanism that lifts the vaporiser up a few mm from the case to enable a user to easily grasp the vaporiser and withdraw it from the case. The lifting mechanism can be spring-based. The case both re-fills the vaporiser with liquid and also re-charges a battery in the vaporiser.

A trigger assembly for an inhaler and an inhaler is provided. The trigger assembly includes: a first component; a second component, the first and second components being configured such that the second component is capable of moving away from the first component to a preloaded position in the case where the second component rotates relative to the first component in a first direction; a first elastic member configured to store energy when the second component moves away from the first component; and an actuator configured to block the second component from leaving the preloaded position in the case where the second component has been moved to the preloaded position, and configured to, upon being triggered, release the second component such that the second component moves to a triggered position toward the first component under the action of the first elastic member.
