  • Patent number: 6862524
    Abstract: System and methods for determining and disseminating current traffic information and/or route information are presented. For example, in accordance with one embodiment of the present invention, traffic condition information is collected from mobile units that provide their location or position information. The traffic condition may be determined, for example, based on the difference between the velocity of each mobile unit and the speed limit corresponding to their location. Furthermore, the fastest routes between two locations may be determined and provided based on historical and/or current conditions and provided to a mobile unit. In accordance with another embodiment of the present invention, route information may be utilized to determine whether a mobile unit (e.g., associated with a vehicle) is allowed or prohibited from traveling along a certain route.

  • Patent number: 6594576
    Abstract: A system and a method for determining and disseminating current traffic information is presented. A traffic data compilation computer linked to a data network collects location data from mobile units, each of which is associated with an identification number. The computer compiles the location data, calculates the velocity of each mobile unit, compares the velocity of each mobile unit against speed limit data stored in a memory, and stores the difference. The traffic data compilation computer determines the traffic condition based on the difference between the velocity of each mobile unit and the speed limit. In addition, traffic data compilation computer may determine the fastest route between point A and point B under the current traffic conditions. Traffic data compilation computer determines the possible routes between point A and point B, retrieves the velocity data from a database, and derives the estimated travel time for each of the possible routes.

  • Patent number: 5861080
    Abstract: An improved tape dispenser and method of use is capable of applying tape to a substrate with only one hand of the user, and comprises a housing having a pair of parallel spaced-apart resilient side walls which can be spread apart to receive a spool of tape rotatably mounted toward the rear of the dispenser; an upper support block mounted between the side walls toward the front end of the dispenser, a cutter blade mounted on the upper support block at the front end of the dispenser, a pressure-applying element in the form of an anvil bar or cushion extending between the side walls behind and below the cutter blade, a lower support bar extending between the side walls behind and below the anvil bar, and biasing means to bias the tape against the lower support bar, whereby, when tape is threaded between the pressure-applying element and the lower support bar, and the dispenser is pressed against a substrate to be taped, the tape is pressed by the biasing means and by a lower edge of the pressure-applying element
