Abstract:
A scent dispensing system includes a scent-impregnated solid polymer material formed by mixing a liquid polymer, a liquid polymer precursor or a liquid solution of a polymer with a scent compound or formulation and solidifying the polymer from the mixture. The system further includes a powered dispersal system including a heating formation. The scent- impregnated solid polymer material is located on or adjacent to the heating formation. The heating formation is adapted to heat the scent-impregnated solid polymer material to a temperature which is greater than the temperature of the surrounding air in order to sublimate scent from the scent-impregnated solid polymer material.
Abstract:
A system for dispensing fluid in response to a sensed property such as an ambient sound comprises a sensor (2) for detecting one or more properties, a processing stage for determining if the one or more sensed properties is/are within a predetermined range and/or above and/or below a predetermined level and dispenser (6) for dispensing a fluid into an area surrounding the system if the one or more sensed properties is/are determined by the processing stage to be within a predetermined range and/or above and/or below a predetermined level and/or value.
