Abstract: The present disclosure provides, in one embodiment, an electronic smoking device comprising a mouthpiece; a vaporizer portion in communication with the mouthpiece; a filter cartridge assembly in communication with the mouthpiece; an inlet check valve; and an outlet check valve. The vaporizer portion comprises a heating element for heating a smoking material housed within the vaporizer portion. The inlet check valve permits air to be inhaled from the vaporizer portion into the mouthpiece, but substantially prohibits air from being exhaled through the mouthpiece into the vaporizer portion. The outlet check valve permits air to be exhaled through the mouthpiece into the filter cartridge assembly, but substantially prohibits air from being inhaled from the filter cartridge assembly into the mouthpiece.

Abstract: The present disclosure provides, in one embodiment, a filter device comprising a mouthpiece, a filter assembly in communication with the mouthpiece for filtering air exhaled into the mouthpiece, and an outlet check valve which permits air to be exhaled through the mouthpiece into the filter assembly, and substantially prohibits air from being inhaled from the filter assembly into the mouthpiece.

Abstract: Novel system, methods, which include machine learning, and device for providing color and fashion recommendations, including for persons with visual impairment such as color blindness or complete blindness.

Abstract: A kit for dispensing disposable stethoscope covers and other instrument covers is provided. The kit may include a cartridge and a dispenser for automatic touch-free dispensing of disposable stethoscope covers. The kit further includes a first spool having a roll of backing member with disposable stethoscope covers disposed thereon and a second spool for receiving the spent backing member after a disposable stethoscope cover has been removed, self-contained within the cartridge. The cartridge is inserted within the dispenser so that a user may insert a stethoscope head through a window of the dispenser to attach to a disposable stethoscope cover. Alternatively, the cartridge or cassette may be comprised of disposable instrument covers so that a user may insert the instrument near or through the window of the dispenser for application of the instrument cover directly to the instrument. The kit may further include a proximity sensor for detecting a user.

Abstract: An accessory e-cigarette and filter assembly that is essentially a holder for both a vaporizer/e-cigarette and an exhale filter is disclosed. The device also allows for removably pairing an exhale filter to a vaporizer and provides impact protection thereto. In the preferred embodiment, a sleeve with parallel channels provides for the filter and e-cigarette to be juxtaposed however a mouthpiece for the filter and a mouthpiece for the e-cigarette are at opposite ends.

Abstract: A personal air filter with a PCB, with or without a microprocessor, and wireless transmission to a mobile ad hoc network is presented herein. In a preferred embodiment, the device is an accessory e-cigarette, (CBD, tobacco, etc.) filter assembly that is essentially configured with one or more sensors and transmission capability. The apparatus is further part of a wider system of the present invention for the purpose of performance monitoring and tracking, making the filter reusable and further extension of its life cycle.

Abstract: An electronic cigarette particularly adaptable to vaporize liquid material also having exhale filter function is disclosed herein. The exhale function is useful to prevent second hand smoke in an enclosed environment, for example. An innovative diverter valve assembly comprises a unique duckbill valve configuration diverting air through a cooker chamber and into a mouthpiece in an inhale function and diverting exhaled air around the cooker chamber in the exhale function and through a filter assembly. A preferred embodiment further introduces a unique shape to the smoking instrument being elliptical in the cross-section and tapering to proximal and distal ends.

Abstract: An accessory e-cigarette filter assembly that is essentially a protective sleeve for both a vaporizer/electronic cigarette and an exhale filter is disclosed. The apparatus is further for the purpose of removably pairing an exhale filter to a vaporizer. Also notably, the invention is a removable mouthpiece having dual valve technology that couples to both the vaporizer and the exhale filter via the protective sleeve. The dual valve technology configured for inhale and exhale could also be adapted to other personal air filter applications as desired.
