Abstract: A hand held passive remote programmer for Radio Frequency Identification readers has a keyboard for turning on any one of several RFID transponder tags in the programmer. Each transponder of the programmer is recognizable by the RFID reader as a program instruction which modifies the operation of the reader, rather than one of a second population of transponder tags which are recognized simply by proximity to the reader, such as tags provided in key cards. In a broader sense, the invention provides a method for wireless linkage of a keypad to an induction type RFID reader.

Abstract: A pack of plastic shopping bags, each being in a rectangular configuration with a central opening below the upper edge to serve as both a means for mounting with other members of the pack on a forwardly and upwardly projecting support arm, and as a handle for the bag when removed from the support arm; and a method for making such bag packs to provide a stiff inner wall and a tacky outer wall for each bag, by co-extruding HMW HDPE of suggested ranges of density and melt index in a specified percentage of the total bag wall thickness with MLDPE of suggested ranges of density and melt index in the complementary percentage of the total wall thickness. The co-extruded tubing is flattened, subjected to corona treatment, may then receive printing and be gusseted, and thereafter cut transversely, sealed at one end of each cut blank, stacked and subjected to a die operation to cut the openings in all stacked blanks.
