An electro-optic display has a plurality of pixels, each of which is capable of displaying two extreme optical states and at least one intermediate gray level. Each pixel is driven from an initial intermediate gray level to one extreme optical state and thence to a first desired intermediate gray level, so producing a first image on the display. The pixel then remains at this first desired intermediate gray level for a finite length of time. The pixel is then driven from this first desired intermediate gray level to the opposed extreme optical state and thence to a second desired intermediate gray level, so producing a second image on the display.

A router is disclosed for use in a network to carry data packets therein. Each router provides a hop along a path through the network extending from a source network address node to a destination network address node. Each route for routing data packets contains a destination network address to a next successive hop along a path between the source network address and the destination network address. Each router has a central routing processor in communication with its forwarders over a control medium to provide routing tables to each forwarder defining the next hop for forwarding received data packets for each destination address. Routing table updates of the forwarders by the central routing processor are sequentially downloaded to all forwarders simultaneously from the central routing processor, using a negative acknowledgement protocol.

Project schedules do not include tasks for Globalization. This method defines and automatically creates globalization tasks that are to be performed during the development of an international product. In this method, a table is created containing various volumes of data and the amount of time required to translate each volume of data. For each volume of data, there is a corresponding translation productivity rate. When a globalization schedule is desired, a user inputs to the method of the present invention, a start date for the Globalization test effort and the date of the product release to manufacturing date. A user then moves the pointer of the constant representing a defined volume of data to the cell in the volume of data table to the volume that corresponds to their current volume for their product. The method then determines the amount of time needed to perform the globalization translation of the volume of data. The method then generates a globalization task schedule within a product development project. In addition, the present invention automatically creates an overall schedule and status report of milestones suitable for team and managerial distribution.

A lossless handover method in vehicular wireless networks is disclosed which is capable of reducing a handover delay and reducing overhead caused by duplicate address detection (DAD) for a new Care-of-Address (CoA) by dividing a handover process into handover at road-sections and handover at intersections. In the handover method, a vehicle continues to use an original CoA configured at an original access router at road-sections even though an AR is changed, thereby reducing a handover delay. A new CoA is configured only at intersections to reduce a binding update time of a home agent which is remotely present in an external network at road-sections. When performing the DAD for a new CoA at intersections, since the vehicle performs the DAD as a background process while performing communication using an original CoA, overhead caused by the DAD can be reduced.
