The invention relates to an ultrasonic mist inhaler (100), comprising: a mouthpiece (1) for inhaling the mist, a liquid reservoir structure (2) comprising a liquid chamber (21) adapted to receive liquid to be atomized, a sonication chamber (22) in fluid communication with the liquid chamber (21), wherein at least part of the liquid reservoir structure (2) and the mouthpiece (1) form the sonication chamber (22).

A droplet delivery device includes a housing with a mouthpiece port or outlet from a nasal device for releasing fluid droplets, a fluid reservoir, and an ejector bracket having a membrane positioned between a mesh with a plurality of openings and a vibrating member that is coupled to an electronic transducer, such as an ultrasonic transducer. The transducer vibrates the vibrating member which causes the membrane to push fluid supplied by the reservoir through the mesh to generate droplets in an ejected stream released through the outlet.

A computer-based system for receiving, analyzing, processing, managing and sending personal health information, and other information in conjunction with use of one or more personal nebulizer or vaporizing devices and personal breath analysis devices. System devices include a personal nebulizer or vaporizing unit with a mouthpiece, which may be detachable and replaceable. The mouthpiece includes an orifice through which vapor is emitted. The substance to be vaporized is contained in an ampoule inserted into the device, where the substance enters an atomization chamber where vaporization is achieved through piezoelectric transducers or atomizers providing sonic or ultrasonic vibration. The substance includes a variety of therapeutic, homeopathic, or naturopathic formulations, remedies, or serums.

An electronic device for producing an aerosol for inhalation by a person includes a mouthpiece located at one of opposite longitudinal ends of the device; a liquid container; a transducer that, when actuated, causes a liquid from the container to be aerosolized such that the aerosol may be inhaled from the device by a person through the mouthpiece; and circuitry and a power supply for actuating the transducer. The mouthpiece, the container, and the transducer are located in-line along a longitudinal axis of a housing of the device extending between the opposite longitudinal ends of the device. The container is located between and separates the transducer and the mouthpiece. The container and the transducer are contained within a cartridge that is insertable into and removable from the housing of the device. The container and the transducer are replaceable by the person when the liquid in the container is depleted.

A nebulizer for producing an inhalable mist of droplets, comprising at least an aerosol generator, a housing having a liquid reservoir and control electronics, the aerosol generator consisting at least of a membrane, a piezo element and a substrate plate, and the control electronics comprising at least an RF generator, a controller, memory and switching elements, and an inductor. The aerosol generator forms a resonant circuit together with the inductor and the control electronics are configured to at least partly excite the aerosol generator to vibrate. The aerosol generator is configured such that aerosol droplets are producible by vibrations and the RF generator is configured to vary the amount of aerosol produced.

One variation of a method for video conferencing includes, during a setup period: accessing a test video feed; and generating a face model, representing facial characteristics of a first user depicted in the test video feed, based on features detected in the test video feed. The method also includes, during an operating period: accessing a video feed; representing constellations of facial landmarks, detected in frames in the video feed, in a feed of facial landmark containers; representing sets of facial muscle actions, detected in frames in the video feed, in a feed of facial expression containers; and transforming the feed of facial landmark containers, the feed of facial expression containers, and the face model into a feed of synthetic face images according to the synthetic face generator.

Systems include a receiving port configured to receive a cartridge configured to store a material capable of being aerosolized, a sensor configured to generate one or more measurements based on ambient conditions of a housing, an aerosolizer configured to aerosolize the material in response to receiving a signal, and a controller comprising one or more processors configured to generate the signal provided to the aerosolizer, and further configured to control operation of the aerosolizer via the signal.

An aerosol-generating device includes a pump. The pump includes a first pump chamber and a second pump chamber on opposing sides of a separation element. Each of the first pump chamber and the second pump chamber have an inlet valve and an outlet valve configured to establish a pumping direction. The pump also includes a first actuator and a second actuator. The first actuator is associated with the first pump chamber and the second actuator is associated with the second pump chamber. The first actuator and the second actuator are each configured to change a chamber volume of the respective pump chamber. The pump further includes a common inlet, and a common outlet. The common inlet and common outlet are in fluid communication with the first pump chamber and the second pump chamber and are configured to establish a flow direction. The pumping direction is aligned with the flow direction.

A dry burning detection method, applied to a vaporizer, includes: obtaining vaporization parameters of a vaporization piece in real time, and calculating a variance between the vaporization parameters and a sample mean, the sample mean being a value representing a vaporization parameter level of a stable vaporization stage of the vaporizer; and determining that the vaporization piece is dry-burned if the variance is greater than a preset variance value corresponding to the vaporization parameter, the preset variance value being used for distinguishing a vaporization parameter fluctuation caused by vaporization dry burning and a vaporization parameter fluctuation caused by non-vaporization dry burning.
