Legal Trends (Part I): Patenting the Internet

Virtually every window of time can be identified by its technological advances. The industrial revolution of the 1800's gave way to the transportation revolution of the early 20th century. The development of synthetics such as nylon and plastics were followed by an electronics revolution built on transistors and early computers. The silicon chip lead to personal computers and chip-driven devices as the 20th century wound down. But these technological changes pale to that which the Internet has brought to the information industry. After 500 years of building on print technologies, the Internet has restructured this industry in a way that is unmatched by other fields of endeavor. The transformation brought on by the Internet, occurring over a fraction of the industry’s life-cycle, has been nothing short of–to use the cliche–revolutionary. All of these technological transformations operate within a number of legal structures. One of the most critical of these structures, yet often least understood, is patent law. In this article, the author explores and explains the complexities involved in determining patentability for Internet-related technologies, such as e-mail, web browsing, TCP/IP software and e-commerce, and in particular, federated searching by WebFeat

Photonic integration enabling new multiplexing concepts in optical board-to-board and rack-to-rack interconnects

New broadband applications are causing the datacenters to proliferate, raising the bar for higher interconnection speeds. So far, optical board-to-board and rack-to-rack interconnects relied primarily on low-cost commodity optical components assembled in a single package. Although this concept proved successful in the first generations of optical-interconnect modules, scalability is a daunting issue as signaling rates extend beyond 25 Gb/s. In this paper we present our work towards the development of two technology platforms for migration beyond Infiniband enhanced data rate (EDR), introducing new concepts in board-to-board and rack-to-rack interconnects. The first platform is developed in the framework of MIRAGE European project and relies on proven VCSEL technology, exploiting the inherent cost, yield, reliability and power consumption advantages of VCSELs. Wavelength multiplexing, PAM-4 modulation and multi-core fiber (MCF) multiplexing are introduced by combining VCSELs with integrated Si and glass photonics as well as BiCMOS electronics. An in-plane MCF-to-SOI interface is demonstrated, allowing coupling from the MCF cores to 340x400 nm Si waveguides. Development of a low-power VCSEL driver with integrated feed-forward equalizer is reported, allowing PAM-4 modulation of a bandwidth-limited VCSEL beyond 25 Gbaud. The second platform, developed within the frames of the European project PHOXTROT, considers the use of modulation formats of increased complexity in the context of optical interconnects. Powered by the evolution of DSP technology and towards an integration path between inter and intra datacenter traffic, this platform investigates optical interconnection system concepts capable to support 16QAM 40GBd data traffic, exploiting the advancements of silicon and polymer technologies

Academical and Research Wiimote Applications

IADIS MULTI CONFERENCE ON COMPUTER SCIENCE AND INFORMATION SYSTEMS 2008 Amsterdam, The Netherlands JULY 22 - 24, 2008This paper proposes the employment of the Wii Remote controller, better known as Wiimote, as an useful tool for educators and researchers. The quick development on fields such as Wireless Sensors and Actuators Networks or Hybrid Systems, and their applications, requires engineers with a solid knowledge in these areas. To achieve this goal the Wiimote becomes a great alternative to other options due to its great variety of analog and digital components, for a very low price, and the good documentation about it existing in Internet. As will be seen in this paper, the possible academical and research uses of the Wiimote are almost endless and cover many interesting problems in control engineering

Quantum Technology: The Second Quantum Revolution

We are currently in the midst of a second quantum revolution. The first quantum revolution gave us new rules that govern physical reality. The second quantum revolution will take these rules and use them to develop new technologies. In this review we discuss the principles upon which quantum technology is based and the tools required to develop it. We discuss a number of examples of research programs that could deliver quantum technologies in coming decades including; quantum information technology, quantum electromechanical systems, coherent quantum electronics, quantum optics and coherent matter technology.Comment: 24 pages and 6 figure

OAST space research and technology applications: Technology transfer successes

The ultimate measure of success in the Space Research and Technology Program is the incorporation of a technology into an operational mission. Charts are presented that describe technology products which OAST has helped support that (1) have been used in a space mission, (2) have been incorporated into the baseline design of a flight system in the development phase, or (3) have been picked up by a commercial or other non-NASA user. We hope that these examples will demonstrate the value of investment in technology. Pictured on the charts are illustrations of the technology product, the mission or user which has incorporated the technology, and where appropriate, results from the mission itself

Limits to Modularity: A Review of the Literature and Evidence from Chip Design

This working paper has been prepared as part of the East-West Center's research project on Globalization of Knowledge Work: Why is Chip Design Moving to Asia. In this paper, Dieter assesses what we know about the limits to modularity and their impact on firm organization and industry structure. He focuses on evidence form chip design, drawing on interview on 2002 and 2003 with a sample of 60 companies and 15 research institutions that are involved in chip design in the US, Taiwan, Korea, China and Malaysia. It is summarized "stylized" propositions of the modularity literature that are well-established, as well as predictions that are controversial. In addition, important limits to modularity and relevant management responses were reviewed.
