  • Publication number: 20240146959
    Abstract: Disclosed are an image encoding method using a skip mode and a device using the method. The image encoding method may comprise the steps of: judging whether there is residual block data of a prediction target block on the basis of predetermined data indicating whether residual block data has been encoded; and, if there is residual block data, restoring the prediction target block on the basis of the residual block data and an intra-screen predictive value of the prediction target block. Consequently, encoding and decoding efficiency can be increased by carrying out the encoding and decoding of screen residual data only for prediction target blocks where there is a need for a residual data block in accordance with screen similarity.

  • Publication number: 20240067065
    Abstract: Provided is a duct docking device for a ventilation seat of a vehicle. The duct docking device enables air to be easily blown to a seatback and a seat cushion with a passenger in a seat using only one blower by enabling a seatback duct mounted at the seatback and a seat cushion duct mounted at the seat cushion to be hermetically docked through a connector duct, etc. at an unfolded position of the seatback in which a passenger can sit, and by enabling the seatback duct mounted at the seatback and the seat cushion duct mounted at the seat cushion to be separated from each other at a folded position of the seatback in consideration of that there is no passenger in the seat.

  • Patent number: 8912505
    Abstract: An electron beam focusing electrode and an electron gun using the same may include a plate having a polygonal through-hole; at least a projecting portion formed on at least one side of the through-hole. By using the electron beam focusing electrode, a spreading phenomenon of an electron beam having a rectangular cross section may be reduced. Further, the output of the electron gun may be increased, and electron beams may be easily focused.

  • Patent number: 8421013
    Abstract: An electromagnetic wave transmission filter may include a substrate and one or more coils. The one or more coils may be at least partly disposed in an opening through the substrate. An electromagnetic camera may include an electromagnetic wave detector array, including a plurality of detector cells for detecting electromagnetic waves, and an electromagnetic wave transmission filter disposed in front of the electromagnetic wave detector array to provide each of the detector cells with an electromagnetic wave of a certain wavelength. The electromagnetic wave transmission filter may includes a substrate and a plurality of coils. At least one of the plurality of coils may be at least partly disposed in each of a plurality of openings through the substrate.

  • Publication number: 20080116807
    Abstract: A magnetron has a cylindrical cathode portion, an anode portion surrounding the cathode portion concentrically, and a resonator circuit connected to the anode portion. Fine modifying portions are periodically formed on the anode portion in an azimuthal direction to encourage electrons in bunching, thereby reducing a start-oscillation time and noise signals.
