EROLEDT OLED driver circuit for energy efficient lighting Instruments used in the IMMS laboratory for the characterisation of the Objectives OLED driver developed at the Institute. The ASIC, laid out specifically for the OLED panel, enables it to run efficiently and compensates for the ”Organic LEDs“, or OLEDs*, have been used for some years already in smartphones and television screens. At the moment, they are not in common use for general lighting purposes. An OLED is, however, highly efficient in its use of energy and about 60% more…

sMobiliTy An energy-optimised wireless sensor solution for traffic applications Making prototype weatherproof, reliable sensors with wireless signalling that can be installed in the ”tactile road“ and will contribute to mobility Objectives 24 with electric vehicles. Photograph: IMMS. Electric vehicles (EVs) have a shorter range and longer ”electrical filling up“ times than do conventional vehicles. For optimum navigation as regards trip time and distance travelled, it is important to have upto-date local information: details of traffic…

By means of the ambient light sensor D3010A, an innovative circuit has been developed, which shows Multitude of Applications at the same time, how circuit development can be The ambient light sensor can be applied wherever realized by IMMS from the idea up to the sample. The visibility conditions must be adapted to the human ambient light sensor (ALS) permits, like shown in fi- eye. In figure 2 you can see exemplarily a laptop and gure 1, to detect and evaluate the brightness of the a cell-phone. In terms of such…

2012 Jahresbericht | Fachartikel S4ECoB (en/de)
S4ECoB Buildings with greater energy efficiency using sound recognition Buildings are responsible for a third of the CO2 emissions and 40% of the total energy consumption in the EU. More than 60% of the energy used there goes into HVAC (heating, ventilation, air conditioning) and lighting.1 As these systems offer the greatest potential for improving the energy balance of buildings, they are the focus of efforts to conserve energy2 in order to achieve the ambitious “20-20-20” climate goals of the EU member states3 – improving energy efficiency…
2012 Jahresbericht | Fachartikel KOMPASSION (en/de)
KOMPASSION Compact adaptive terminal antenna for interference-free satellite navigation Unmanned flying vehicles such as quadrocopters are being used ever more. Long-discussed fields of application for this new technology are catastrophe relief services or the autonomous transport of such urgently required goods as donated organs. However, although there has been enormous progress in their development over recent years, these aircraft have not so far been used for safety-critical scenarios. Autonomous movement, it must be remembered,…

TESCA Direct mirror drive for Terahertz Scanner Spiegelantrieb. Grafik: IMMS. Security checks at airports and major public events involve long queues and much trouble. A “terahertz camera” would enable people to be scanned in future for hidden, possibly dangerous, objects – such as weapons or explosives – effectively scanned as they simply passed by. The acquisition of any object's emissions of intrinsic electromagnetic waves in the THz band carries with it no health risks whatsoever. The technology1 will render real-time examination from…

3DNeuroN – 3D bi-directional interface with the brain The microelectronic chip developed by IMMS forms part of a system Motivation which is intended to detect (and to stimulate) neuron activity in three dimensions. The image shows the probe card used in wafer-level testing of the 3DNeuroN chips. Photograph: IMMS. 26 When humans have superficial wounds to arms and legs, the body is able to regenerate damaged sections of the peripheral nerves. Injuries to the head and the spinal chord, and conditions like multiple sclerosis and…
