Abstract: Provided are an inter prediction method and a motion compensation method. The inter prediction method includes: performing inter prediction on a current image by using a long-term reference image stored in a decoded picture buffer; determining residual data and a motion vector of the current image generated via the inter prediction; and determining least significant bit (LSB) information as a long-term reference index indicating the long-term reference image by dividing picture order count (POC) information of the long-term reference image into most significant bit (MSB) information and the LSB information.

Abstract: Disclosed is a core for a current transformer, which forms an upper core in a round shape, and is disposed at a position lower than the center of a power line having both ends of the upper core received, thereby minimizing the stress of a magnetic path, and increases the permeability, thereby enhancing the magnetic induction efficiency. The disclosed core for the current transformer includes an upper core curved in a semi-circular shape to have a receiving groove formed therein, and having both ends extended downwards to be disposed to be spaced apart from each other and a lower core disposed on the lower portion of the upper core, and having both ends extended upwards to be disposed to face both ends of the upper core.

Abstract: Provided is a sterilized water spray device for sterilizing the inner wall of a toilet and a bidet seat having the same. A sterilized water spray device according to the present invention includes: a housing into which sterilized water flows; a tubular nozzle part for spraying the sterilized water flowed into the housing, a through nozzles disposed at one end of the nozzle part, to a toilet; and a driving part for rotating the nozzle part.

Abstract: The present invention relates to a sterilized water spray device for sterilizing the inner wall of a toilet and a bidet seat having the same. A sterilized water spray device according to an embodiment of the present invention comprises: a housing into which sterilized water flows; a tubular nozzle part for spraying the sterilized water flowed into the housing, through nozzles disposed at one end of the nozzle part, to a toilet; and a driving part for rotating the nozzle part.

Abstract: Provided is a toilet seat assembly comprising: a bidet housing for defining the appearance of a bidet; a hinge member which is fixed to the inner side of the bidet housing and is provided with a shaft, wherein the hinge member is provided with a circular ring-shaped coupling groove formed along the outer circumference of the shaft; and a toilet seat connected to the shaft so as to allow rotation thereon, wherein the bidet housing is provided with a coupling protrusion protruding to the inner side so as to be inserted into the coupling groove. Thus, it is possible to prevent moisture from permeating into the inside of the bidet housing, and to facilitate wiring of wires for supplying electricity to a heating device provided in the toilet seat.

Abstract: A nozzle assembly and a bidet including the same are provided. The nozzle assembly may include a plurality of sitz bath nozzles dispensing jets of water, wherein a plurality of water streams formed by the jets of water dispensed by the plurality of sitz bath nozzles contact each other at a water contact point to form fountain-like water streams. Thus, a clinical effect of the sitz bath is brought about as the pressure inside the anus is reduced. In addition, secondary diseases such as the urinary tract infection and the like for female users may be prevented, and the stress exerted to the anus at the beginning of the sitz bath function may be significantly decreased.

Abstract: A bidet according to an embodiment of the present invention includes: a bidet body to which a toilet seat having an opening is hingedly coupled; and a nozzle assembly disposed in the bidet body. The nozzle assembly includes: a nozzle body part forming an outer appearance thereof; and a sitz bath discharging port for spraying water and forming a water-current, the sitz bath water discharging port being disposed in the nozzle body part.

Abstract: The present invention provides a nozzle assembly for a bidet, the nozzle assembly comprising: a nozzle unit which moves along a curved line and comprises a water supply hose connected to a water supply source; and a driving unit having a winding member for rotating/driving such that the length of extension of the nozzle unit is adjusted, the driving unit guaranteeing that the nozzle unit moves along a curved line, where the length of extension of the nozzle unit is adjusted in multiple steps, and the withdrawing rotation angle, by which the winding member rotates in order to change the length of extension of the nozzle unit from one of the steps to the adjacent upper step, is different in each step. The length of extension of the nozzle unit can be adjusted such that the interval of water ejection positions is constant.
