First compact method for all-optical 3R- and phase regeneration
- Compact state of the art 3R-regeneration systems for an optical phase-coded data signal are not capable of enhancing the quality of the phase information. Since DPSK systems offer 3 dB better performance, phase-coded systems and thus phase regeneration would be favourable in all-optical networks. The offered technology now allows the entire, all-optical regeneration of DPSK and other phase-coded optical data signals under a conversion of the carrier wavelength. The compact design of the regeneration module should open the possibility to integrate it easily into an optical sub-system avoiding fibre technology. The proposed method also offers the possibility of converting the phase-coded optical signal into an amplitude-coded optical signal. This can be operated independently.

Highly Efficient Light Emitters - The Route to Green Lasers
- The emission of green laser light is of great importance for several applications and procedures particularly in biology, medicine or multimedia. A powerful green laser could revolutionize the market for portable beamers. So far, semiconductor based light emitters, such as laser pointers, convert infrared into green light (Diode Pumped Solid State Frequency Doubled [DPSSFD] laser technology). A significant drawback of this technique is the loss of power and efficiency. In addition, these devices are limited when it comes to reduction in size for use in integrated devices. The new technology involves a Zn-Cd- semiconductor material that features a band gap in the 2,2 eV - 2,5 eV range which allows the emission of green light. Contrary to current state of the art techniques the innovative technique produces a semiconductor material that is capable to emit green light directly. Ongoing development demonstrated successfully the optical induced emission of green light.

Autonomous Service Robot for Vacuuming Floors
- A new exploration method for mobile robots is especially suitable for home and office environments. The robot also provides a flexible cleaning system, allowing adaptation to any kind of floor surface with any kind of obstacle and avoiding unnecessary repeat cleaning of the same area. Self-localisation means that the method does not require a precise global map, nor does it rely on external markers located in the rooms or areas to be cleaned. Instead, the robot creates its own rough map by scanning the environment, so that the map comprises every obstacle which the robot can then avoid. Iterative scanning allows adaptation to arbitrary obstacles.

Methods for searching with semantic similarity scores in one or more ontologies
- The invention provides techniques for indexing and searching document collections and databases using ontologies. Categories or individual documents within the database that are annotated to the terms of the ontology can be searched and prioritized using statistical models to test for significance of the similarity scores of queries against the database.
