Abstract: In a method for collecting and transporting handouts at a tradeshow, a handouts valet and shipping system provider location is established. A plurality of handouts valet carts and customer ship-back cartons are provided at the location. When visiting the provider location, a tradeshow attendee obtains one of the handouts valet carts together with the ship-back carton from the provider, and provides a mailing address to the provider for the ship-back of the carton. The carton is placed on the cart. The tradeshow attendee thus becomes a customer of the provider for the cart with the ship-back carton thereon. When the customer is ready to leave the tradeshow, the customer drops off the carton at the system provider location, and the system provider mails the carton with the handouts to the customer's mailing address.

Abstract: In a method and system for removing particles from a surface, a portable, compressed gas can is provided containing a particle removal gas. An air ionizer unit is connected to the gas can. A high voltage potential is selectively actuated at a time when a nozzle of the gas can is depressed, the high voltage potential being positioned in the gas stream to create air ions in the gas stream which facilitate removal of the particles.

Abstract: An anti-clog shaker system and method utilizes a shaker container and a cap attached to the shaker container. The cap has a surface with a plurality of apertures through which particles contained within the container will pass when the shaker container is inverted and shook. An agitator is provided comprising a shank having at least one protruding element. As the agitator is rotated, the agitator breaks up particles in the container. A winder is connected to the agitator. A wiper element is also connected to the agitator so that as the winder is rotated to rotate the agitator, the wiper element also wipes away particles which may adhere in a region at the apertures of the shaker cap.
