| 20100007241 | WAVEGUIDE COMPONENTS ON THE BASIS OF ACOUSTIC SURFACE WAVES, AND THEIR USE - The invention relates to waveguide components based on acoustic surface waves, comprising at least one interdigital converter for exciting acoustic surface waves in a piezoelectric substrate or a piezoelectric layer. The object of the invention is to change known waveguide components, comprising at least one interdigital converter for exciting acoustic surface waves in a piezoelectric substrate or a piezoelectric layer, such that no reflectors are necessary with an otherwise equivalent function. The inventive waveguide components are characterized in that the interdigital converter(s) a) is or are disposed at a defined distance over the piezoelectric substrate or the piezoelectric layer for exciting wave fields, or b) is or are in contact with the piezoelectric substrate or the piezoelectric layer, wherein in version a) the piezoelectric substrate is designed as a ring and the piezoelectric layer is designed as a circular region. In case of version b), the interdigital converter and/or the piezoelectric layer form circular regions. The components can be used for example as resonators, filters, oscillators and sensors. | 01-14-2010 |

| 20100151474 | Multifunctional Device For Diagnostics and Method For Testing Biological Objects - A multifunctional device for measuring fluorescence, luminescence and light transmission for diagnostics. A sample carrier is designed in the form of a biochip, cell, pan or microplate. The device comprises a first and second group of screens mounted behind the rear surface of a sample solid carrier. Light sources of the sample are provided with light-absorbing elements for suppressing light reflected from the front surface of the sample carrier and from screen surfaces. Screen holders allow for alternatively mounting light reflective/retroreflective screens to maximize fluorescent or luminescent signal. A diffusing screen measures light transmission through the sample. Light-absorbing screens behind the rear surface of the sample and light-absorbing elements on light sources from the sample's top surface, increase signal-to-noise ratio. Said device permits measuring signals on biochip surfaces and in solutions during hybridization or amplification reactions. The device and diagnostic method are suitable for mass screening of biological material samples. | 06-17-2010 |
