    摘要: An electrostatic spray disinfecting system is integrated into a mobile environment to enable the mobile environment to be automatically subjected to an electrostatic spraying operation when the mobile environment is moving or stationary without the need for a human operator to participate in the spraying operation. An electrostatic sprayer of the system is mechanically coupled to a structure of the mobile environment in a preselected position relative to an internal compartment of the mobile environment. A reservoir of disinfecting material and is fluidly coupled to the electrostatic sprayer for delivering a flow of the disinfecting material to the sprayer. When an electrical switching circuit is placed in an On state, electrical power is delivered to the electrostatic sprayer to electrostatically charge the particles of the disinfecting material delivered to the electrostatic sprayer and to cause the electrostatically-charged particles to be sprayed from the electrostatic spray nozzle into the internal compartment.

    摘要: A folding stroller having a structural frame formed of a plurality of rigid support members. The stroller is provided with a skirt formed of a flexible material. The skirt can be disposed around at least a portion of an outer perimeter of the stroller to create a visual impression of something other than an ordinary stroller. For example, the skirt can create a visual impression of a vehicle such as an automobile, truck, airplane, spacecraft, an animal or a character. The skirt can be formed of fabric, plastic sheeting or film, or a mesh. A suspension frame is provided for suspending the skirt along a least a portion of an upper edge thereof. The suspension frame can at least partially define a profile of the vehicle, animal or character. The suspension frame folds with the structural frame of the stroller for ease of storage.
