Abstract: A mounting apparatus is disclosed and includes a base that is supported by a ground surface, and a holder supported by the base and having a holder recess configured such that a portion of a mobility vehicle is inserted thereinto. The holder supports the portion of the mobility vehicle such that the mobility vehicle is prevented from deviating from an upright state when the portion of the mobility vehicle is inserted into the holder recess.

Abstract: A mobility charging device comprises a measurement unit configured to measure a voltage of a battery of a mobility device when the mobility device is electrically connected to an input/output interface, a determination unit configured to receive the voltage of the battery from the measurement unit, and determine a charging mode among a plurality of charging modes according to the voltage of the battery, and a charging unit configured to differently set cut-off voltages correspondingly to the plurality of charging modes, and provide charging voltage corresponding to a cut-off voltage set correspondingly to the charging mode to the mobility device through the input/output interface.

Abstract: Disclosed is an apparatus and method for processing a multichannel audio signal. A multichannel audio signal processing method may include: generating an N-channel audio signal of N channels by down-mixing an M-channel audio signal of M channels; and generating a stereo audio signal by performing binaural rendering of the N-channel audio signal.

Abstract: Provided is an apparatus for parking a mobility device to minimize road occupancy and safely park a mobility device. The apparatus includes: a clamp formed to be fastened to an installation object, while surrounding the installation object; a connection portion having one end connected to the clamp; and a holder rotatably connected to the other end of the connection portion through a first hinge and coupled to a portion of the mobility device.

Abstract: Disclosed are a system and method for managing a shared personal mobility device (SPM) capable of acquiring accurate location information of the SPM. The system for managing the SPM may include a dock configured to store SPMs, and an SPM management server configured to receive, from the dock and using an LPWA protocol, state information associated with the doc. The state information may include coordinates of the dock. The SPM management server may be further configured to receive location information associated with a returned SPM, and update, based on the coordinates of the dock, the location information associated with the returned SPM.

Abstract: A method for charging a micromobility and a charging stand therefor are provided. The charging stand includes a power device that supplies power, a mounting part including a charging part and a holding part configured to dock with at least one micromobility, a power conversion device including at least one converter or an inverter, and a control device that executes an operation for charging the at least one micromobility based on that the mounting part is mounted on the at least one micromobility. The control device receives power supplied from outside by means of the power device, converts the supplied power into a specified DC voltage, outputs at least a portion of the specified DC voltage to the charging part, converts the specified DC voltage into a specified AC voltage, and outputs at least a portion of the specified AC voltage to the charging part.

Abstract: An apparatus for extracting a signal from convolutive mixtures includes a receiving unit which includes two or more receivers and receives a signal; a transfer function calculation unit which calculates transfer functions for demixing; and a demixing unit which demixes the received signal using the calculated transfer functions. The transfer function is determined such that a signal is extracted from a source closest to the receivers, and is calculated on the basis of a transfer function for a path to each receiver being approximated to a delta function as closer to the source.
