Fast Communication Using Variable Pulse Widths Explained

The inventors propose a new method which allows the use of different pulse widths. The motivation is to realize fast communication between transmitters and receivers. The contained information (the data value) gets encoded in the length of a transmitted pulse and finally gets decoded in an efficient way by the receiver. Through a corresponding evaluation logic, which is switched in parallel to the line driver, it can be concluded with the disappearance of the original signal at its actual length. This method can be preferably used in application-specific hardware such as ASICs and FPGAs, as these modules enable the parallel processing of signals at the hardware level.

Quantitative prediction of the date of delivery of production animals

Even today it is possible to provide quantitative information about the beginning of birth by using simple sensors. The invention supplements warnings with information on the probable beginning of the birth. These quantitative predictions are based on the indirect measurement of prenatal anxiety in animals. Such agitation can be expressed in vocalization, locomotion and interaction. This can be measured by using acoustic-, light-, ultrasonic- or radar- sensors. The prediction itself is based on empirically proven assumptions about the natural history of the measured parameters during the prenatal period. Parameters such as age-related differences are taken into account.

Method for Cell monitoring

The invention describes a method and device to monitor cellular activity and vitality with higher accuracy than common methods. This method is based on measuring the specific cellular form and its development. To do so, several parameters are created, which interact with the neighbour cells and which are comparable over the course of the monitoring. The monitoring is done by recording the cellular movement and growth by video recording through a microscope. At the start of the compatibility testing, the substrate or material and the cells are brought together and get monitored over the course of 4 to 12 hours. All changes to the cells get recorded via video. After this, the entirety of the movement data from the cells is compared with reference data from tests with similar substrates. By doing so the invention delivers infor-mation about effect and toxicity of the tested substrate or material.

Method and device for silicon filling of the eye

The invention describes a subsequent adaptive enlargement of the contact surface between the silicon oil and the retina for an optimal fit. This means that the size of the silicon oil bubble is adapted to fit to the volume of the eye socket. To achieve this, the inventor proposes to implant one or several biocompatible balloons together with the silicon oil into the eye. Those balloons absorb the water that is trying to fill the volume created by differences in the eye socket. By doing so, the balloon enlarges its volume and with this, and fills up the remaining space between silicon oil and the retina. Because of this, the retina is fully under pressure at all times. When the eye pressure rises, the balloons release the water. By doing so, the balloons are regulating the eye pressure and ensure adaptation to the varying volume of the eye socket.

Magnetic Alternating Current Imaging AFM

The invention relates to a method for AFM in which it is possible to measure magnetic information from single, isolated magnetic markers in on the scale of nm.The method is used to differentiate between marked and unmarked arrears, for measuring the magnetic AC-susceptibility of the marker and to determinate the geometry of a marker. Hereby the measured signal is further processed by an amplifier.
The method utilises nanoparticles (marker), which are placed on or in a sample. Because of the alternating magnetic field these particles are stimulated to create a magnetic flow, which is dependent on the AC-susceptibility of the particle and on with the external alternat-ing field. With this effect, the entire magnetic flow in the area around the marker is changed. Furthermore, the entire sample is scanned in 2-D or 3-D and differences in the magnetic flow, which generate a magnetic interference, are measured by detecting the oscillation of the AFM tip. This oscillation is the measurement signal, which makes it possible to measure smaller magnetic interac-tions.

Boosting Solar Cell Efficiency: Regeneration Breakthrough at Konstanz

The efficiency of solar cells made of CZ silicon decreases by more than 1% in absolute figures under sunlight within a few hours (light induced degradation – LID). At the University of Konstanz a method was developed that makes it possible to stabilize the efficiency of the solar cell at nearly its output level. During production the solar cells are regenerated by either illumination at temperatures of between 100 and 230 degrees or applying voltage. The method can be easily integrated in the conventional manufacturing process and allows for an increase in efficiency by up to 5% rel.

Scientists at the University of Konstanz have developed a measuring device for non-permanent contacting of busbarless solar cells that allows for precise and direct characterization of electrical properties. As each contact finger can be contacted repeatedly over reversibly releasable connections the device allows for accurate measurement of I-V characteristics without requiring subsequent adjustment with correction factors.

MOD-FC – Modular fuel cell stack

A modern fuel cell is usually made of a stack of individual cells that are mechanically pressed together. In MOD-FC the pressing takes place not mechanically but hydraulically. Due to the complete flushing of separate individual cells with the hydraulic medium, a homogeneous pressing of the inner cell components is ensured. In addition, the hydraulic medium can be directly used as a cooling medium. This ensures a homogeneous electric current generation among the surface and also that no life shortening hot spots appear.
By the nearly ideal operating conditions MOD-FC are capable to examine in-situ membrane electrode units. First functional models are already in use (see figure). A plurality of simultaneously reproducible samples can be examined under the same operating conditions, which improve the quality of test results and reduces significantly the amount of sampling tests. Moreover, individual elements can be replaced by separate individual cells without great effort, due to the modular design of the stacks. In contrast to conventional fuel cell stacks MOD-FC can thus be maintained at a cellular basis.

Automated Organ Segmentation from Multi-Channel MRT Data

The inventions are serving to segment organs or organ areas out of multi-channeled volumetric MRT data sets.
To do so, the first invention uses segmentation outcomes from Trial data, which was generated by hand and recorded by several people. After recording an MRT dataset, a first pre-segmentation method is used.In this case, the grayscale information from the MRT data is used along with characteristic regions to create probability data for the organ.
A further development of this technique delivers the possibility to use the image slices from the training data to determine at least three classes of characteristic shape. For every class a support vector machine is trained. By using an exclusion method on each other they are able to detect the characteristic organ form. Based on this segmented area a patient specific probability data set is generated, on which a further segmentation technique is used. By combining both methods, a reliable fully automated segmentation is possible, with one or more emphases. Furthermore this application is less susceptible to variability in the MRT data. It is also possible to process one channel volumetric data.

Detecting Antigen Presentation for Cancer Immunotherapy

Efficient processing and surface expression of tumor antigens are a prerequisite for successful immune-based cancer therapies. Unfortunately, spatial distribution of antigens is very difficult to determine with standard histological techniques. So cells might harbor tumor antigens inside the cytoplasm, but lack the appropriate MHC I or MHC II presentation on their cell surface. The current invention discloses a simple method to determine MHC-restricted presentation of any antigen of interest on the cell surface.
