  • Publication number: 20240092141
    Abstract: An air conditioning device for a vehicle includes: a housing having an inside divided into an inflow space, a heat exchange space, and an outflow space, which are straightly arranged, and having a plurality of discharge ports, which communicates with an interior, at the inflow space; a blowing unit disposed at the inflow space of the housing and configured to blow air; a heat exchange unit disposed at the heat exchange space of the housing and configured to adjust a temperature of conditioned air by exchanging heat with air; and an opening-closing door disposed at the outflow space of the housing and configured to open and close the plurality of discharge ports such that conditioned air at an adjusted temperature selectively flows to the plurality of discharge ports. The air conditioning device adjusts the temperature of conditioned air for respective modes and reduces a flow resistance of air.

  • Publication number: 20090027010
    Abstract: A portable communication device and method for charging through discernment of a charging cable are provided. When the portable communication device is connected to an external charging device through a connector in order to charge a power source in the portable communication device, a configuration signal is received from the external charging device through a positive data line and a negative data line of the connector, a logic characteristic value is output according to the received configuration signal, the charging cable is discerned by analyzing a current characteristic through connection with a resistance circuit according to the on/off state of a switch which operates according to the logic characteristic value, and a control operation is performed such that a battery is charged from the external charging device through the corresponding charging cable.
