  • Publication number: 20230404737
    Abstract: A new constructive arrangement is endoprosthesis having comprises a metallic structure (1) integrally coated by a melted inner layer and an outer layer of coating, and at least one device of reducing axial expansion (4) associated with the melted coating layers. The device of reducing axial expansion is an axially capillary structure (4) that, arranged along at least one axial segment of the endoprosthesis, is axially arranged between the result of the hot-melting between the inner laminate of the outer coating layer and the inner laminate (32) of the inner coating layer.

  • Patent number: 11454682
    Abstract: Various embodiments of the present technology use low-frequency magnetic signals for communication and location applications. Compared to the case of traditionally used radio-frequency electromagnetic signals, their advantage in the presence of strong signal attenuation is in the extended spatial range. Some embodiments use an optically pumped atomic magnetometer operated as a sensor to achieve high detection sensitivity. The spatial range can be extended to hundreds of meters when noise is suppressed by the use of the available sensor sensitivity. In some embodiments, a one-channel spread-spectrum signal processing technique can be used to eliminate the systematic fluctuations coming from power grid (or another source) harmonics and reduce the ambient noise by averaging uncorrelated fluctuations from the environment.

  • Publication number: 20190361061
    Abstract: A mapping probe provides real-time signal sampling and recovery from engineered electromagnetic interference and includes: a trigger voltage source that synchronizes transmission of primary electromagnetic waves; primary electromagnetic wave synthesizers that receive a trigger voltage signal and produce time-varying voltage signals; transmitters that receive time-varying voltage signals and synchronously transmit primary electromagnetic waves, such that the primary electromagnetic waves are subjected to scattering by a structural entity to produce scattered electromagnetic waves; receivers that receive scattered electromagnetic waves and produce receiver signals based on the scattered electromagnetic waves; a conversion stage that receives the receiver signals and the trigger voltage signal and produces converted data; and a render that receives the converted data and produces a map of the structural entity.

  • Patent number: 7450353
    Abstract: A magnetoresistive sensing apparatus is disclosed, comprising a magnetic film having a zig-zag shaped structure, a central axis, and a magnetization associated with the magnetic film, wherein the zig-zag shaped structure biases the magnetization direction alternately at positive and negative angles thereof, thereby permitting the magnetoresistive sensing apparatus to be sensitive to a magnetic field parallel to the axis of the magnetoresistive sensing apparatus and insensitive to magnetic fields perpendicular to the axis.
