  • Patent number: 11860296
    Abstract: A radar arrangement includes a printed circuit board (PCB), an electronic component, and an antenna. The electronic component is arranged on the PCB and is used to generate a high-frequency signal. The PCB has at least four electrically conductive layers separated from one another by at least three electrically insulating layers. A first conductive inner layer is adjacent to a first conductive outer layer, and a second conductive inner layer is adjacent to a second conductive outer layer. The electronic component is arranged on the first conductive outer layer. The antenna is formed at least partially in the second outer layer. The signal generated by the electronic component is transmitted to the antenna, which is formed at least partially in the second conductive outer layer of the PCB, through a region of the conductive inner layers and insulating inner layers of the PCB.

  • Patent number: 11476561
    Abstract: A radar antenna arrangement includes a plurality of transmitting elements and with a plurality of receiving elements. The transmitting elements are arranged in a transmitting arrangement and the receiving elements are arranged in a receiving arrangement, in each case in fields of a regularly hexagonally parqueted surface. An associated virtual antenna arrangement of virtual antenna elements results from the geometrical convolution of the transmitting arrangement with the receiving arrangement. High angular resolution and good alignability with good directional independence can be achieved by arranging the receiving elements in the receiving arrangement and the transmitting elements in the transmitting arrangement so that the virtual antenna elements in the virtual antenna arrangement are arranged without overlap.

  • Patent number: 10341314
    Abstract: A method of security and verifiability of an electronic vote, comprising reception of a temporary voting ballot, during which a temporary voting ballot is received by a voting entity, the temporary voting ballot being encrypted by a public voting encryption key; reception of a validation voting ballot, during which a validation voting ballot is received from the voting entity, the validation voting ballot being encrypted by a public validation encryption key; decrypting the validation voting ballot by a private validation key associated with the public validation encryption key; validating a validation request generated from the decrypted validation voting ballot sent to the voting entity; the preceding steps being repeated until the acceptance of the validation request by the voting entity, after which the encrypted temporary voting ballot is registered as a definitive voting ballot awaiting its counting.

  • Publication number: 20150066976
    Abstract: In embodiments, one or more computer-readable media may have instructions stored thereon which, when executed by a processor of a computing device, provide the computing device with a recurring text identification service. The recurring text identification service may be configured, in some embodiments, to receive a request to identify recurring text within a plurality of documents. The recurring text identification service may be further configured to analyze individual segments of the plurality of documents to generate segment identifiers respectively associated with the segments. In embodiments, the segment identifiers may be based on content of the segments. In embodiments, segments with the same content may have equivalent segment identifiers.

  • Publication number: 20050095587
    Abstract: The present invention provides purified disease detection and treatment molecule polynucleotides (mddt). Also encompassed are the polypeptides (MDDT) encoded by mddt. The invention also provides for the use of mddt, or complements, oligonucleotides, or fragments thereof in diagnostic assays. The invention further provides for vectors and host cells containing mddt for the expression of MDDT. The invention additionally provides for the use of isolated and purified MDDT to induce anitbodies and to screen libraries of compounds and the use of anti-MDDT antibodies in diagnostic assays. Also provided are microarrays containing mddt and methods of use.
