Abstract: A combination female-oriented receiver and male-oriented mount, said the mounting side of said receiver in electrical communication with electrical connections from a junction box or mounting plate, the receiving side of said receiver having electrical plates also in electrical communication with said junction box or mounting plate. Said receiver further provided with access points and a race to receive said mount and a pin slot, said electrical plates being positioned such that when corresponding conducting surfaces on said mount are rotated in said race in proper position by inserting dog ears of said mount through said access points and turning said mount in said race, said conducting surfaces become in electrical communication with said receiver's conducting plates, said race further providing a weight-bearing surface to hold said mount in position along with the weight of an electrical fixture upon which said mount had been removably affixed.

Abstract: A particle filling line comprises a vertically-oriented conduit that includes a conduit hollow. The conduit includes a conduit top and a conduit bottom. The conduit bottom defines an outlet. The conduit is arranged so that particles supplied to the conduit top flow through the outlet to be received by one or more containers disposed on a movable conveyor belt. The conduit hollow includes one or more conduit hollow elements disposed therein. The one or more conduit hollow elements include any of a plurality of agitators and an auger. The particle filling line is arranged for determining a resistance that is based on the spacing between the one or more conduit hollow elements and the conduit inner walls. When the resistance is determined to be less than a threshold resistance value, the particle filling process ceases.

Abstract: A system and method are provided for notifying a user of a document left at a xerographic apparatus, such as a printer or copier. The system includes a sensor module for sensing the document and determining whether the user is within a predetermined distance of the xerographic apparatus. The system further includes a notification module for notifying the user of the document left if the copier user is outside the predetermined distance of the copier. The system and method can utilize RFID transponders each worn by a respective copier user or input data for determining the identity of the user. Notification can be accomplished by one of several methods, such as transmitting an electronic message to the user, actuating an alarm located near or at the xerographic apparatus, and preventing further use of the apparatus until the document is retrieved.
