peer-to-peer
- We offer a powerful peer-to-peer scheme for the efficient organization of very large scale dynamically distributed systems such as ad hoc mobile networks and computer grids. The architecture is realized as a logical overlay of a two-dimensional concentric multi-ring topology (illustrated above) with the best robust resource distribution and discovery algorithm available.

TuneInNet
- Networking and the network in its core form determine the crucial backbone of today’s information technology. Networks need to handle a variety of highly diverse require-ments and a certain level of technological complexity has been reached. This level requires a number of highly sophisticated control algorithms and mechanisms, such as routing, flow control, or congestion control for operation and maintenance. The present invention relates to a method for forwarding data packets in a communication network. Further, it relates to a communication network having flooding transport properties without any IP-addressing.

Self-focused Laser Cutting
- High-power femtosecond (fs) laser pulses have been found to propagate in transparent media and even in the atmosphere as thin white-light filaments. These filaments can be attributed to nonlinear optical phenomena. They can propagate over distances of several kilometres exhibiting power intensities on the order of 5x1013 W/cm2. If the filament hits a solid target, also there a plasma is ignited. Without any need for focussing equipment, the laser beam can be used for welding or cutting processes. The spectroscopic analysis of the generated plasma is an additional application allowing determination of solid state composition of the target. We offer a new method for material processing and material analysis by laser filaments.

In-plane polarized transitions
- Quantum-well inter-subband devices, such as quantum-well infrared photo-detectors (QWIPs) and quantum cascade lasers (QCLs) are ideal for a variety of ground and space-based applications. Night vision, early warning systems, navigation, flight control systems, weather monitoring, security and surveillance are among the different applications based on QWIPs. QCLs are ideal candidates for the remote sensing of gases in the atmosphere. This new technology is an improvement on coupling light into or out of QWIPs and QCLs, respectively. Both types of devices form a base for novel approaches to infrared imaging or remote sensing of gases, respectively. In particular, the new technology allows one to detect or emit photons vertically. This has tremendous advantages for both detectors and emitters due to the ease of coupling light into or out of the device. We offer a new type of semiconductor quantum-well inter-subband devices, which can be manufactured with standard GaAs deposition technology. The technology incorporates self-organized three-dimensional nanostructures in the planar barrier so that in-plane translational symmetry is broken.

Memory Cell, and a Method for Storing Data
- The most important factors for computer storage are: read/write speeds, storage density, endurance, reliability, and cost. DRAMs are short-term memories with high speed but the data must be refreshed over 100 times per second to maintain its memory. Flash memory can store data for years without refreshing, but writes information about 1000 times slower than DRAM. The novel solution is a quantum dot (QD) based memory that can provide the best of both: long-term storage with write speeds nearly as fast as DRAM. The QDs are made from a blend of two semiconductors, InAs and GaAs. One difference to normal flash memory is varying the barrier height whilst retaining charge by electrical means. A further difference is growing the dots in the depletion region of a pn junction so that holes are stored in the QDs. By changing the bias on the depletion region, one can easily vary the barrier height, enabling either retention or the insertion of charge into the QD. Charge removal is achieved by using tunnelling. The read mechanism is similar to that of flash memory.
