Abstract: A programmable control unit for a vacuum cleaning system, such as central vacuum cleaning system. A control unit is programmed after manufacture to execute a particular control program for performing various diagnostic and operational functions including user interface, voltage level detecting, voltage monitoring, current monitoring, user interface, power supply control, temperature monitoring, AC line frequency detection, operation data recording, speed control program selection, expansion bus interface and service tool interface. Power control to the vacuum motor is facilitated by the control unit directly through a triode for alternating current (TRIAC). Manufacturing costs are reduced by producing a single programmable control unit that can be programmed with a control program corresponding to a variety of different vacuum cleaning devices across a manufacturer's product line.

Abstract: A storage, display and dispensing apparatus for tickets of various sizes that accounts for the tickets dispensed during a selected time period. The apparatus includes a bin housing for storing a pack of tickets, a ticket dispensing assembly through which the tickets are dispensed and includes a friction wheel assembly that is actuated as tickets pass through the ticket dispensing assembly. An optical sensing element is also employed to sense indicia on the tickets to coact with the friction wheel assembly to provide a ticket count.
