This paper describes SHAPE TAPE™, a thin array of fiber optic curvature sensors laminated on a ribbon substrate, arranged to sense bend and twist. The resulting signals are used to build a three dimensional computer model containing six degree of freedom position and orientation information for any location along the ribbon. The tape can be used to derive dynamic or static shape information from objects to which it is attached or scanned over. This is particularly useful where attachment is only partial, since shape tape “knows where it is” relative to a starting location. Measurements can be performed where cameras cannot see, without the use of magnetic fields. Applications include simulation, film animation, computer aided design, robotics, biomechanics, and crash testing.
Examines the Internet’s potential for becoming an information highway. Defines the information highway and the Internet. Describes the characteristics of an information highway. The concept of an information highway puts some requirements on the infrastructure. The users of an information highway, who are located in the residential and business environment, have their share of requirements as well, but they focus on the requirements put forward by the services or applications they will use on an information highway. Checks whether the Internet has implemented these properties and how, or if work is going on to develop them. The framework for this discussion is the TCP/IP reference model. Places some emphasis on the IP next generation protocol, IP version 6 (IPv6). Provides an overview showing all the properties with an indication of how well the posed requirements are met. Concludes that the Internet certainly has potential for becoming an information highway.
