Abstract: Methods of classifying tobacco include imaging tobacco with an imaging system to obtain an image and classifying the tobacco as very low nicotine (VLN) or traditional based on the obtained image. The imaging system includes a hyperspectral camera and an image processing system.

Abstract: A virtual or augmented reality smoking system is provided herein. A smoker using the system can experience a virtual reality of smoking by puffing on a cigarette shaped article and experiencing the taste or aroma from the article while simultaneously viewing a generated image of a burning cigarette and exhaled and sidestream smoke. Additionally, the room environment may be simulated to give the experience of smoking in a setting of the smoker's choice (virtual reality) or the image of a burning cigarette and smoke may be superimposed on a live or natural image of the smoker's environment (augmented reality).

Abstract: A process for the on line production of cigarette filters comprises the steps of conveying a continuous thin flexible substrate past a source of smoke altering particulate material, such as adsorbents, catalysts and flavorants. An electrostatic charge is applied onto the substrate upstream of the source of particulate material. A layer of particulate material from the source is deposited onto the substrate with the thickness of the layer depending upon the strength of the electrostatic charge. The coated substrate is then cut into pieces, and the pieces are placed into the cavities between spaced apart filter components. In an alternative process, filter paper is coated with smoke altering particulate material by electrostatic deposition techniques, and spaced apart filter components are placed onto the particulate coated filter paper which is then folded around the filter components.
