A method of maintaining a desired level of a dispersed liquid within an occupiable semi-enclosed space is provided. The method includes: providing a liquid diffusion appliance including a liquid to be dispersed; operating the liquid diffusion appliance to disperse the liquid into the occupiable semi-enclosed space throughout a treatment period in which the occupiable space is subjected to entry and exit of occupants to and from the occupiable semi-enclosed space; sensing the concentration of one or more chemical components of the dispersed liquid within the occupiable semi-enclosed space; and modifying the operation of the liquid diffusion appliance based on the concentration of the one or more chemical components of the dispersed liquid within the occupiable semi-enclosed space to achieve a desired concentration.

A removable replaceable cartridge for use with a liquid diffusing device. The cartridge includes a venturi, a conduit extending to the venturi, a mixing area and an outlet path for atomizing and dispersing a liquid within the cartridge. A diffusion device including a removable replaceable cartridge received within a housing. The housing includes a source of compressed gas which is directed into the cartridge. A venturi head with a unitary body for use with a diffusion device.

A dual camera system for viewing a coupling of a hitch to a trailer, such as on a semi tractor truck, includes two video cameras. Two doors that open automatically by arms and linkages expose the video cameras when the vehicle is shifted into reverse. A split screen view is shown to the driver rearward toward the trailer and forward toward the hitch plate. The arms and linkages automatically close the doors after the vehicle is shifted out of reverse, such as after a delay that permits the driver to determine if the hitch latch is secure. The linkages are sliding linkages with a spring so that the doors can be opened manually for cleaning the lenses of the cameras.

A dual camera system for viewing a coupling of a hitch to a trailer, such as on a semi tractor truck, includes a camera housing having two video cameras. The housing includes two doors that open automatically by a motor, arms and linkages when the vehicle is shifted into reverse. A split screen view is shown to the driver rearward toward the trailer and forward toward the hitch plate. The motor, arms and linkages automatically close the doors after the vehicle is shifted out of reverse, such as after a delay to determine if the hitch latch is secure. The linkages are sliding linkages with a spring so that the doors can be opened manually for cleaning the lenses of the cameras. A heating element is inside the housing.

A method of controlling operation of a diffusion appliance to treat the atmosphere within an enclosed space. The method may include programming the operation of the appliance according to a control scheme specifying a flow rate of liquid to a diffusion means and a periodic operation of the diffusion means. Control schemes may be associated with different volumes of spaces to be treated by the appliance, the rate of decay of the liquid within the space to be treated and the level of concentration of the liquid desired within the space.

A method and system of controlling operation of a diffusion appliance to treat the atmosphere within an enclosed space. The appliance may be programmed to operate according to a control scheme specifying a flow rate of liquid to a diffusion means and a periodic operation of the diffusion means. Control schemes may be associated with different volumes of spaces to be treated by the appliance. Anti-fatigue schemes may provide variation of the flow rate or periodic operation of the appliance. Initiation controls schemes may be used to start treatment of the space before the appliance is programmed to operate according to one of the control schemes.
