Abstract: A tutorial software program provides information about the operation of an electronics assembly machine and a computer software interface used to operate the electronics assembly machine. A host transmits the tutorial program over a network, such as the Internet, to a computer at a customer's location. The information provided by the tutorial software program includes pictures representing the computer software interface, text that provides information about the electronics assembly machine and the computer software interface, audio that provides information about the electronics assembly machine, and video that shows the electronics assembly machine in use. Systems and methods for providing the tutorial program are also provided. The tutorial program allows a customer to instruct employees how to fully operate the electronics assembly machine without having to train employees on the machine itself, which could result in costly downtime of the machine.

Abstract: A suction device has a flexible cup member whose lower surface defines a flat central zone surrounded by an annular zone sloping inwardly and upwardly at an angle of 2.degree. to 10.degree. with the central zone. An article holder, such as a beverage can receptacle, has a rigid circular base centrally secured to the upper surface of the cup member, opposite the central zone thereof. Any tilting or lifting of the article holder attendantly tilts or pulls the central zone of the cup member upwardly, thereby establishing a retentive suction in a self-setting manner.
