  • Publication number: 20220146236
    Abstract: A horn antenna for emitting an electromagnetic HPEM microwave pulse along a central axis contains a microwave generator for the pulse having a waveguide along the central axis with a generator opening for the pulse, and a horn structure for shaping the pulse with an input opening and an emission opening for the pulse. The generator contains at least one HPEM source for the pulse. Each HPEM source contains at least two antennas for pulse components, disposed in succession in parallel with the central axis. The pulse is formed as a sum of the pulse components. A method for reconstructing a horn antenna to form the horn antenna with increased power, includes constructively increasing a number of antennas toward a respective HPEM source and orienting remaining antennas in a row relative to the first antenna, increasing the waveguide length, and keeping other dimensions of the horn antenna unchanged.

  • Patent number: 11290515
    Abstract: Systems, apparatuses, and methods for implementing real-time, low-latency packetization protocols for live compressed video data are disclosed. A wireless transmitter includes at least a codec and a media access control (MAC) layer unit. In order for the codec to communicate with the MAC layer unit, the codec encodes the compression ratio in a header embedded inside the encoded video stream. The MAC layer unit extracts the compression ratio from the header and determines a modulation coding scheme (MCS) for transferring the video stream based on the compression ratio. The MAC layer unit and the codec also implement a feedback loop such that the MAC layer unit can command the codec to adjust the compression ratio. Since the changes to the video might not be implemented immediately, the MAC layer unit relies on the header to determine when the video data is coming in with the requested compression ratio.

  • Patent number: 11230265
    Abstract: A window wiping assembly for removing moisture and debris from a side window of a vehicle includes a positioning element that is mountable to an exterior surface of a vehicle door having a window opening positioned therein. The positioning element extends substantially between opposed endpoints of a lower edge of the window opening. A wiper blade is engaged to and extends from an inner face of the positioning element so that an outer edge of the wiper blade contacts an exterior face of a window that is positioned in the window opening. The wiper blade extends substantially between opposed ends of the positioning element. The wiper blade removes moisture and debris from the exterior face of the window as the window is raised and lowered within the window opening.

  • Patent number: 11221396
    Abstract: In a method for generating a transillumination signal of a section of the subsurface, an HPEM radiation source radiates an electromagnetic pulse into the section for the purpose of exciting electromagnetically reactive structures to emit an electromagnetic response signal. For the pulse, a pulse duration of at most 500 ns, a center frequency in the range between 10 MHz and 10 GHz, and a bandwidth in the range from 10% to 150% of the center frequency is set. The transillumination signal is formed as the sum of response signals received at a measuring location. In a method for detecting a cavity in the subsurface, the above method is carried out, and the structures are detected from the transillumination signal with the aid of a detection method, and the cavity is detected if the structures satisfy a detection criterion.

  • Patent number: 11194015
    Abstract: A high-power electromagnetic source for HPEM pulses in a desired radiation direction includes at least three antennas fixed in relation to one another for pulse components, wherein at least two groups of antennas with a respective main direction are present, and a control unit for the activation and phase position of the pulse components for the superimposition for the HPEM pulse, wherein the current radiation direction of said pulse is selectable in an angle range around the main direction. A vehicle with an HPEM source has the antennas mounted in a fixed position or a support for the antennas is pivotably mounted on the vehicle. In a method for emitting the HPEM pulse, all antennas are controlled in order to select the radiation direction in the angle range of less than 360°.

  • Patent number: 11140368
    Abstract: Systems, apparatuses, and methods for scheduling beamforming training during vertical blanking intervals (VBIs) are disclosed. A system includes a transmitter sending a video stream over a wireless link to a receiver. The wireless link between the transmitter and the receiver has capacity characteristics that fluctuate with variations in the environment. To combat the fluctuating capacity characteristics of the link, the transmitter and the receiver perform periodic beamforming training procedures to determine whether to adjust the beamforming characteristics of their respective antennas. To avoid interfering with the video data being sent, the system waits until a VBI to perform a beamforming training procedure. If the beamforming training procedure cannot be completed in a single VBI, then multiple VBIs can be used for performing separate portions of the beamforming training procedure. In one embodiment, the system can perform a beamforming training procedure every N VBIs, where N is a positive integer.

    Abstract: An electronic dazzling element has at least one optical emitter for emitting light pulses, which contains an electronic light-emitting device for generating light pulses, and a control device for controlling the light-emitting device of the optical emitter. In order to reduce the brightness reduction of the light pulses as a distance from the dazzling element increases, the optical emitter is configured to emit a collimated light beam. In order to simultaneously achieve the dazzling effect in as large a spatial region as possible, a beam direction of the collimated light beam may be changed.

  • Patent number: 10959111
    Abstract: Systems, apparatuses, and methods for implementing enhanced beamforming training procedures are disclosed. A system includes a transmitter communicating over a wireless link with a receiver. To maintain a high quality of transmission over the wireless link, the transmitter and receiver perform periodic beamforming training procedures to test the various sectors of the transmit and receive antennas. In a wide sector sweep procedure, the transmitter and receiver test wide sectors to find the best wide transmit and receive sectors for transferring data. Then in a narrow sector sweep procedure, narrow sectors within and/or adjacent to the best wide sectors are tested, to find the best narrow sectors. This reduces the amount of sectors that are tested during the enhanced beamforming training procedure by skipping those narrow sectors that are far away from the best wide sectors.
