Abstract: A device for storing and dispensing different product possesses at least two interlocking product dispenser units each possessing a product dispensing outlet through which stored product may be selectively dispensed.

Abstract: A surveillance system and method that utilize computer vision technology and background subtraction to monitor, recognize, and track objects or unusual activities within user specified boundaries. The system and method comprises at least one camera and at least one computer with a software program showing one or multiple windows of camera's field of views in real time. The program allows users to define one or multiple boundaries within any window. The program further utilizes background subtraction technique to establish normal “home-position” of objects within defined boundaries. The program compares current image of the objects against the normal “home-position” to determine/calculate the difference of pixel intensity values. If the difference is beyond the predetermine threshold, the program will flag the movement of the object and give off alert.

Abstract: A Shop Vacuum Cleaner commonly utilized for the Industrial and non industrial environments alike. Our shop vacuum cleaner, hereafter known as the “Retrac-A-Vac”. Said Retrac-A-Vac is vacuum cleaning product which incorporates extremely unique features. Said Retrac-A-Vac's uniqueness rests in its' ability and “on demand”, to in real time extend, deploy and retract, draw back its' vacuum hose. Said Retrac-A-Vac's real time hose manipulation feature though unique in itself, is supported by other internal mechanical advantages within unit. The additional features inasmuch when grouped together, collectively and in a mutual sense support the main feature's true functionality. As a result and united together they are indeed unique notwithstanding in themselves. The Retrac-A-Vac embodiment encompasses a cylindrical outer housing covering.
