This paper describes a codesign environment based on the WWW (World Wide Web) and its implementation. Tool invocations and their respective results are linked using hypertext documents. We show how to configure a WWW browser for spawning design tools and how frequent tasks like documentation generation and retrieval are facilitated. The design flow can be adopted to the given application very easily. In addition we introduce the concept of a work flow called ‘design by documentation’. A WWW link to the results is given and experience using it in a codesign project is described.
Filling the Pipe
(1995)
An Information on Demand teleservice that was developed at the German National Research Center for Information Technology (GMD) provides remote access to multimedia information consisting of audio, video, and text [jonas et al. 94]. It uses a bidirectional narrowband message link between the end user and the service provider, and a unidirectional broadband data link from the service provider to the end user. Since the IoD teleservice is used across a satellite connection (among others), it turned out to be necessary to implement an access protocol that is optimized for the access of real-time multimedia data across a long-delay high-bandwidth link, a long fat pipe [jacobsen et al. 92]. This paper introduces the MediaService Protocol (MSP) and describes a prototype implementation (version 0.6).
Three emerging technologies are combined in a setup that has been installed and tested at GMD - the German National Research Center for Information Technology: 1. Multimedia Telecooperation Applications; 2. ATM-based high-speed networks; 3. Satellite links. The results are promising: After some initial problems, the complete scenario is up and running, allowing the interconnection of local high-speed infrastructures in rural areas to a core network via satellite. This paper describes the R&D background and state- of-the-art that led us to this approach. It then describes the communication infrastructure and the application infra- structure of the setup, the problems we had and the solu- tions we found. Finally, our experiences are summarized, and an outlook is made for future implementations.
The Information Footprint
(1995)
Die Erfindung betrifft eine Spritzeinheit (1) für eine durch eine elektronische Steuerung gesteuerte Spritzgießmaschine, bestehend aus einer eine Schnecke (2) aufweisende Plastifiziereinheit (3), einem Antriebsmotor (4) und einem Getriebe (5) für den rotatorischen Antrieb der Schnecke (2). Das Getriebe (5) besteht aus einem Gehäuse, in dem eine mit dem Antriebsmotor (4) verbundene hydraulische Pumpe (7) angeordnet ist, die mit einem hydraulischen Motor (8) gekoppelt ist, der hydraulische Motor (8) treibt vorzugsweise über ein mechanisches Getriebe (9) die Schnecke (2) der Plastifiziereinheit (3) an. Erfindungsgemäß wird es damit möglich, mit geringem Aufwand die Rotationsdrehzahl der Schnecke (2) stufenlos zu regeln und so die gesamte Drehmomentenkennlinie des Antriebsmotors (4) zu nutzen. Das Getriebe wird vorzugsweise in kompakter Form ausgeführt, wobei die hydraulische Pumpe (7), der hydraulische Motor (8) und das mechanische Getriebe (9), das vorzugsweise als Planetengetriebe ausgeführt ist, koaxial angeordnet sind.
