Abstract: In a cellular telecommunications network a method for facilitating communications comprises receiving information elements from a cellular data communications device, said information elements being in a format conforming with a session-based message protocol, each information element including a header portion and a plurality of payload portions; extracting machine information from at least at least one of said payload portions; and generating an output message corresponding to at least one of said payload portions. The cellular data communications device generates information elements using information gathered from one or more information sensing, actuating and/or locating components.

Abstract: The present invention provides a dual blade utility knife useful in various fields. In particular, the dual blade utility knife contains a fixed cutting element contained in a gap that inhibits injury or accidents, a.k.a. a safety knife. The second cutting element is designed to be retractable. The retractable blade can be retracted during use of the safety blade, inhibiting injury or accidents, but extended to make cuts, such as an initial cut in a material.
