  • Patent number: 11982756
    Abstract: A method, implemented by a computer, for determining a position of a personal mobility device (PMD) comprises: estimating a position of a PMD based on a first wireless signal; determining whether the PMD is within an intermediate area between a first area and a second area, based on an estimated position of the PMD; determining whether the PMD moves to the second area, by using both the first wireless signal and a second wireless signal; and determining position of the PMD by using any one of the first wireless signal and the second wireless signal based on a movement of the PMD to the second area.

  • Patent number: 11936075
    Abstract: Disclosed are a separator for fuel cells capable of minimizing the volume of a system and the use of sealants, and a stack for fuel cells, more particularly, a stack for solid oxide fuel cells, including the same. Specifically, by adding a metal sheet having a specific shape, position and size to the separator, the stress applied to the sealant can be uniformized, and thus the oxidizing agent and fuel can be separated and electrically isolated using only a piece of sealant. Therefore, the stack for fuel cells is characterized in that there is no variation in temperature, reactant concentration, power, or the like between respective unit cells, so delamination and microcracks do not occur, the volume is minimized, and the power density per unit volume is very high.

  • Publication number: 20240073416
    Abstract: The present invention relates to an apparatus and method for encoding and decoding an image by skip encoding. The image-encoding method by skip encoding, which performs intra-prediction, comprises: performing a filtering operation on the signal which is reconstructed prior to an encoding object signal in an encoding object image; using the filtered reconstructed signal to generate a prediction signal for the encoding object signal; setting the generated prediction signal as a reconstruction signal for the encoding object signal; and not encoding the residual signal which can be generated on the basis of the difference between the encoding object signal and the prediction signal, thereby performing skip encoding on the encoding object signal.
