Technology Offerings

The invention is based on a measuring device consisting of a transmitter and two receivers. The transmitter transmits a sinusoidal signal, which is band pass filtered, amplified and converted into a squarewave signal. Depending on the distance of the transmitter to the individual receivers, the received signals have a certain phase shift in relation to each other and now enter two inputs in the actual measuring system. On the lines, a signal is sampled and each fed to a XOR gate at regular intervals. There, a logical “1” is passed, if only one square-wave signal was received. The duration of the “1” indicates the relative phasing of the input signals at the physical tap. Each XOR gate passes its signal to a counter connected to the system clock. At each clock, the counters who received during clock rise just a “1” from the XOR gate are incremented by one. The results of the individual counters vary, but take in a minimum of one place. As a result, the transmitter can clearly be located after calibration.

The invention relates to a method for email communication based on the exchange of MX-Records (Mail-Exchange-Records).
With the invention, those public MX-Records get controlled and verified by a more complex MXK-Record (Mail-Exchange-Key). Generating those keys can either be done by every person themselves or by a central position. These generated keys only need to be digitally signed by the service provider. The provider itself is not included in the process of generating the keys, which means he is not faced with additional expenses. Because no third party is required to generate the key, this method is an easy to use and secure method for the encryption and sending of emails.
With some modifications, this technique is also suitable for the encryption of telephone or SMS communication.

An apparatus for holding back, and diverting, fish in bodies of water by the arrangement of parallel cables braces between two or more abtuments, wherein the distance between the cables is small enough to prevent fish from swimming through the apparatus

We have developed a new method for improvement of cellulase and hemicellulase production in Trichoderma reesei by overexpression of a developmental regulator.

The present invention specifically provides a novel vaccine formulation
suitable for ocular immunization and provides a method for inducing a local and systemic immune response. The combination of the three components antigen & corpusculate bodies (eg.Bortedella pertussis (wBP)) & adjuvans showed the highest rise in IgA antibody titers in tears and sera when compared to other immunization groups. Immunization via the conjunctiva with TTd plus wBP and adjuvant resulted in a 33% survival rate of challenged mice compared to a 0% survival rate in non-immunized animals.

USE OF ERYTHROPOIETIN FOR THE TREATMENT OF
FRIEDREICH´S ATAXIA:
In addition to its neuro- and cardioprotective properties recombinant human erythropoietin (rhuEPO) significantly increases frataxin expression in primary lymphocytes from FApatients, and other cell types like neurons and primary human cardiac cells in vitro. (Sturm et.al 2005, Eur. J.Clin. Invest. 35(11):711-7) rhuEPO was successfully tested as a treatment for Friedreich`s ataxia in Phase IIa/IIb and dosefinding studies.
