An apparatus to provide scent or other substances (e.g., active agent) includes a thin profile delivery apparatus that includes an actuator (e.g., nebulizer) and drive circuit to generate a spray, aerosol or vapor. The apparatus may have a slot to removably a media cartridge that carries the scent or other substances. The apparatus may include two contacts (e.g., buttons), opposed to one another across a dimension of the apparatus. Activation may require both engagement of both contacts, for instance concurrently, or even successive engagement of both contacts, in quick succession. Activation may further require a correct orientation of the apparatus. The apparatus may have a form factor similar to a conventional credit or debit card, and may be pliable or pliably resilient. The delivery apparatus can be used in entertainment (e.g., food or cooking programming), and in healthcare (e.g., control of metabolism).

A drug delivery device includes a housing defining a shell, a drug delivery assembly at least partially disposed within the housing, a cap defining an opening and being adapted to at least partially cover an end of the housing, at least one electronic component, a power source which powers the at least one electronic component, and a switch assembly. The drug delivery assembly comprises a guard which engages an inner surface of the housing and is movable between a first position, a second position, and a third position relative to the housing and is adapted to restrict external contact with a cannula. The switch assembly causes the power source to provide power to the at least one electronic component when the cap is removed from the housing, restrict the power source from providing power when the cap is coupled to the housing and the guard is in the first position, and cause the power source to provide power when the cap is coupled to the housing and the guard is in the third position.

A method of treating respiratory system tissue, includes operations of generating a plume of particles of a treating solution from a nebulizer, inhaling particles of the treating solution, delaying exhalation of an inhalation having particles of the treating solution therein, and determining whether a dose of the treating solution has been delivered, wherein the treating solution is a solution of at least 40% ethyl alcohol, by volume.

System and methods for controlling healthcare devices and systems using voice commands are presented. In some aspects a listening device may receive voice command from a person. The voice command may be translated into human readable or machine readable text via a speech-to-text service. A control component may receive the text and send device-specific instructions to a medical device associated with a patient based on the translated voice command. In response to the instructions, the medical device may take an action on a patient. Some examples of actions taken may include setting an alarm limit on a monitor actively monitoring a patient and adjusting the amount of medication delivered by an infusion pump. Because these devices may be controlled using a voice command, in some cases, no physical or manual interaction is needed with the device. As such, multiple devices may be hands-free controlled from any location.

In example implementations, an apparatus is provided. The apparatus includes a display, a biometric sensor, and a processor. The display is to play content. The biometric sensor is to collect biometric data of an individual. The processor is communicatively coupled to the display and the biometric sensor. The processor is to calculate a level of cognitive load based on the biometric data and to adjust an amount of noise in the content based on the level of cognitive load of the individual.

A charger for an electronic nicotine delivery systems (“ENDS”) device, which may include aerosol delivery devices provides functionality for authentication, including age verification. Such devices may be restricted based on age or other factors that require some form of authentication, verification, and/or identification to satisfy the restriction. The accessory or charger may provide or connect with a verification system for confirming an age of a user. If the authentication or verification is not satisfied, the charger or accessory will not charge the device, rendering it unusable.

The present disclosure provides an image display method and an image display system for alleviating motion sickness. The image display method includes: obtaining a number of shock and speed information of a transportation; comparing at least one of the shock and speed information with one or more than one corresponding threshold to determine whether motion sickness occurs; and in response to the determination that motion sickness occurs, positioning a position of a first image displayed on a display unit according to the shock and speed information.

A method of determining facial metrics of a patient includes: capturing a first image of the patient with an image capturing device positioned in a first known position with the assistance of a positioning device, capturing a second image of the patient with the image capturing device positioned in a second known position different that the first known position with the assistance of the positioning device, and determining facial metrics of the patient by analyzing the first image and the second image.

System and method for identification and verification of authorization of a subject to use a substance delivery device.

Various exemplary drug delivery devices with on-board drug destruction, drug products utilizing the same, and methods of using drug delivery devices with on-board drug destruction are provided. In general, a nasal drug delivery device configured to dispense a drug therefrom into a nose includes a destruction mechanism configured to destroy drug contained in the drug delivery device. The destruction mechanism can be configured to destroy the drug before a first actuation of the drug delivery device to deliver the drug therefrom such that the destruction mechanism destroys substantially all of the drug contained in the drug delivery device. Alternatively or in addition, the destruction mechanism can be configured to destroy the drug after a first actuation of the drug delivery device to deliver the drug therefrom such that the destruction mechanism destroys substantially all of the drug remaining in the drug delivery device.
