Abstract: A traffic control system employing location based services is disclosed. The system includes a wireless device disposed in each of a plurality of vehicles, the wireless device operable to log onto a wireless network and transmit the location based services, and a master traffic controller coupled to the wireless network and operable to receive the location based services. A method of traffic control employing location based services includes the steps of (a) logging a vehicle onto a wireless network; (b) computing a network address for the vehicle; (c) receiving location based services data for the vehicle; (d) predicting and optimizing traffic flow based on the received location based services data; (e) switching traffic signals based upon the predicted and optimized traffic flow; and (f) repeating steps (a) through (f) at a pre-determined frequency.

Abstract: A punching and perforating cylinder and a die and anvil cylinder are part of a computer paper processing system producing the line holes and the cross perforation in a continuous paper web. The PUNCH/PERF cylinder is mounted on an upper shaft, while the DIE/ANVIL cylinder is mounted on a lower shaft. The upper and lower shafts are rotatably engaged by a set of gears. At both ends of the PUNCH/PERF cylinder, holes are located to accept the PUNCHES. At both ends of the DIE/ANVIL cylinder, holes are located to accept the DIES. While the two cylinders are rolling together, the punches engage with the dies and form the punched line holes in the continuous paper web. The PUNCH/PERF cylinder has longitudinally formed slots, providing the space for the cross perforating blades and for the cross perforating blade clamping bars. The DIE/ANVIL cylinder has longitudinally formed slots, providing the space for the hardened anvil bars.

Abstract: A folder unit according to the teachings of the preferred embodiment of the present invention is shown as including front and rear sets of spirals for folding a continuous web of paper. The spirals are driven by first and second shafts whose ends extend through elongated slots formed in the side plates of the unit. A third drive shaft is further provided rotatably related to the first and second shafts and including a slideable helical gear. When the helical gear is slid on the third drive shaft, the third drive shaft is forced to rotate due to the helix of the helical gears simultaneously changing the rotational position of the spiral sets with respect to the other folder unit components. To prevent the spiral gear boxes from rotating with the first and second shafts, anti-rotation bars are provided which also extend through the elongated slots of the side plates.

Abstract: A dual harmonic gear phasing device forming a part of a web-forming printing tower or other web-handling station is disclosed which allows static or dynamic, 360.degree. infinite phase alterations of web-contacting rollers for coarse and fine tuning of the registration of a multiple-station printing press. The phasing device comprises an enclosed, oil filled structure having a pair of tandem coupled harmonic drive gears respectively connected through gearing or the like to the press drive and to a desired roller for phase changing purposes. Each phasing device also includes a selectively operable stepper motor coupled to one of the harmonic gears for effecting phase alterations. The harmonic gears serve as a 1:1 gear ratio transmission during normal running operations. The phasing device can be used on hard impression or perfecting printing towers, and on other types of web-handling equipment where proper registration is important, such as numbering and punching units.
