  • Publication number: 20240122544
    Abstract: Methods, systems, and devices for experimental programs are described. A method includes acquiring baseline PPG data from a user via a wearable device throughout a time interval, and displaying one or more experimental programs via a user device based on the baseline PPG data, where each experimental program is associated with one or more behavioral changes. Upon a selection of an experimental program, the method includes acquiring additional PPG data from the user via the wearable device throughout a time interval of the experimental program. The method includes identifying adherence of the user to a behavioral change of the experimental program based on the additional PPG data and/or information received via the user device. The method further includes displaying, via the user device, changes between the baseline PPG data and the additional PPG data based on identifying the adherence to the behavioral change.

  • Publication number: 20190053533
    Abstract: A tobacco smoking mixture including an ammonia-release compound adapted to be formed into a lit-end cigarette is provided. The ammonia-release compound is incorporated in or on tobacco cut filler in an amount effective to reduce the cytotoxicity, and/or selective smoke constituents of cigarette smoke. Exemplary ammonia-release compounds include ammonium acetate, ammonium hydroxide, hexammine cobalt (III) chloride, hexammine cobalt (III) acetate, and combinations thereof. The ammonia-release compounds can release ammonia at temperatures between about 60° C. and about 400° C. Ammonia-release compounds can be combined with additives, such as glycerine, cobalt acetate, copper (II) acetate, zinc acetate, other metal salts or combinations thereof, to further reduce the cytotoxicity of cigarette smoke.

  • Patent number: 8511522
    Abstract: A valve having a sleeve comprising a sleeve wall including an inner surface; and a plug positioned within the sleeve, the plug comprising at least one portion that is elastically deformable. The plug forms a blind hole extending into the plug from one end thereof to define a plug side wall, and a flow passage that extends through the plug side wall that is either open or openable. The plug defines a valve closed position in an unstressed state, yet is capable of elastically deforming to define a flow channel between the plug and the sleeve in a valve open position. A dispenser containing such a valve is also provided.
