Abstract: A case forming machine for erecting cases from knock down case form to an open form and move an opened case downward to a bottom forming station using a fixed and a moveable jaw system is improved by providing a plurality of radially spaced, concentric stabilizer bars fixed to the fixed jaw and arranged to form concentric segments of circles centered on the pivotal axis of the moveable jaw and having their bottom edges in a radial plane relative to the pivotal axis. Also provided is a micrometer type adjustment mechanism that is used for adjusting the gap between the fixed and moveable jaws when the jaws are in the parallel pick-up position.

Abstract: Techniques employed to guarantee isochronous operation of a wireless system to within Federal Communication Commission, Unlicensed Personal Communication System (UPCS) requirements. Synchronization and frequency stability is tracked and maintained for more than one frequency references of stratum 3 or better in a wireless telecommunication system.

Abstract: A plug in daughtercard with an edge connector having pins configured to maintain a low impedance power supply path and accurately control the impedance of lines carrying signals. A low impedance power supply path is provided with pins of the daughtercard organized in rows and columns with some rows providing all power supply voltage and ground return contact pins extending across the entire daughtercard edge. Rows providing power supply voltage and ground return are further interleaved between rows providing signal path connection pins to maximize the number of power supply voltage and return pins to assure a low impedance power supply path is provided to components throughout a daughtercard. Signal line impedance matching is provided using the rows of pins providing the power supply voltage and ground return connections. Ground return pins in such rows are coupled through metal plates which simulate a larger metal ground plane.
