  • Patent number: 11612019
    Abstract: The present disclosure provides an air heater. The air heater comprises: a direct heat generating portion configured to be heated by an electric current supplied from outside; an indirect heat generating portion configured to be heated by conductive heat, which is supplied by physical contact with the heated direct heat generating portion, and configured to heat air coming in through an inlet opening formed on one side while the air is passing through an outlet opening formed on the other side; and a housing made of an insulating material that provides a space where the direct heat generating portion and the indirect heat generating portion are placed, and that comprises an air inlet on one side through which the air is drawn in from outside and an air vent on the other side through which the air is released.

  • Publication number: 20040037241
    Abstract: Disclosed herein is an interlaced frequency division duplexing method for a duplex communication system. The present invention is constructed to estimate feedback information of a transmission frequency channel using a reception frequency channel. In the interlaced frequency division duplexing method, a frequency band of the duplex communication system is divided into a plurality of frequency channels so as to guarantee similarity between channel characteristics of neighboring frequency channels. Transmission and reception channels are alternately allocated to the plural frequency channels.
