Abstract:
A wireless digital personal communications system (or PCS) having a plurality of radio cell base stations, fixed terminals, and portable handset terminals, each having a predetermined radio cell coverage area. The wireless PCS has a full digital network interface. The personal communications system facilitates the interconnection and switching of PCS call traffic through the digital network interface and the public switched telephone network, or any switched network. The personal communications system has voice/data/image (or any combination thereof) and incoming and outgoing calling capability. The PCS is fully operational and compatible with any and all modulation approaches selected for wireless communications. The intercell protocol hand-off being provided through distributed logic which is implemented in software that is resident in the intelligent portable handset terminals, in the intelligent fixed terminals, in the intelligent base stations, and in the public switched telephone network (or any switched network). Alternative embodiments of the present invention include a wireless digital personal communications system having authentication means for authenticating a remote device; a wireless digital personal communications system having a combination of authentication means for authenticating a remote device and security means for securing signal and message content between an intelligent base station and a remote device, the security means including a predetermined encryption and decryption technique; a wireless digital personal communications system having dynamic zone grouping of portable handset terminals or fixed terminals; and a wireless digital personal communications system having call forwarding for unanswered calls.
Abstract:
A paperboard carton blank is disclosed which includes first and second panels having side walls connected thereto by scored fold lines formed between a respective side wall and a respective edge the panel, with one of the side walls of the first panel and one of the side walls of the second panel being congruent and at least one predetermined edge of the second panel being devoid of a side wall. A sealing flap is provided which extends a predetermined distance from a predetermined edge of one of the side walls of the first panel with the predetermined edge of the side wall being that edge which extends adjacent to the predetermined edge of the second panel of a carton formed from the blank. An opening means is also provided which is defined by the predetermined edge of the second panel and regions of weakness formed in the second panel which extend from the predetermined edge of the second panel for permitting access to the inside of the formed carton. The opening means includes an opening force receiving means defined by the regions of weakness, the predetermined edge of the second panel and a line of weakness which extends between the regions of weakness substantially parallel to and spaced a predetermined distance greater than or equal to the predetermined distance of the sealing flap from the predetermined edge of the second panel. Once opened, the carton formed from the above blank is capable of reclosure to form a vent opening which permits steam to escape.
Abstract:
A paperboard carton blank including a first panel having side walls connected thereto by scored fold lines formed between a respective one of the side walls and a respective edge of the first panel is disclosed. A second panel is provided having a side wall connected thereto by a scored fold line formed between the side wall and an edge of the second panel. A seal flap is provided and extends a predetermined distance from a predetermined edge of one of the side walls of the first panel, the predetermined edge of the side wall being that edge which extends adjacent to a predetermined edge of the second panel of a carton formed from the blank. The blank also includes opposing end panels connected to each of the side walls and the first and second panels with each of the end walls having a die cut edge. A predetermined region of each of the end panels is skived adjacent to the die cut edge in order to reduce the resultant thickness of the end panels when sealed and a cover flap is provided to overlie the end panels of the sealed carton. An opening feature defined by the predetermined edge of the second panel and regions of weakness formed in the second panel extending from the predetermined edge of the second panel for permitting access to the inside of a carton formed from the blank is also provided with the regions of weakness being formed of a pair of substantially parallel lines of weakness with at least one of lines of weakness being a knurled line of weakness. The above paperboard blank being used to form a carton of a high barrier carton construction for containing a product placed therein wherein no die cut edges are exposed within the interior of the carton and the resultant carton exhibits a smooth continuous end cover.
