Abstract: A method of communicating non-native print objects in MO:DCA Architecture for controlling and operating RFID writer or reader devices without requiring separate control data streams or systems to be implemented at the host computer. Data references and command identifiers are placed by application program means at the host computer into the page description data so that RFID information can be retrieved and downloaded to the printer and RFID apparatus when the print data is being processed in the print server or main processor of the printer without interfering with normal operation of the printer itself.

Abstract: Product presentations are managed in a retail environment. Responsive to a customer buying a product, an unsold product present along a route traversed by the customer in the retail environment and an actual behavior of the customer while traversing the route, are identified. The unsold product is associated with the product and with an expected behavior to purchase the unsold products based on an actual purchase of the product by the customer.

Abstract: A self-aligning, simple to use and reliable child/pet safety gate (2) that is removably mounted by a support assembly (4) to an existing room door (12) by hanging the support assembly on the room side doorknob (10) without the use of mounting hardware is disclosed. This design allows the gate to be used or stored while so mounted to the room door. Further, with the gate in its stored, hidden position behind the door, the existing room door can still be opened and closed in a normal fashion. Yet, it is a simple matter to place and secure the gate's blocking assembly (6) in its operative or blocking position by pivoting it to block the open area and then latching it to the door frame using a locking strap (54) and pin (60) and the existing door lock bolt aperture (62) to secure the blocking assembly.
