Abstract: A method for manufacturing a printed circuit board having an embedded component is disclosed. The method includes: forming at least one contact bump and at least one electrode bump on one side of a base substrate; mounting the component such that the electrode bump is in correspondence with a contact terminal of the component; stacking an insulation layer, in which an opening is formed in correspondence to the component, on the one side of the base substrate, such that the contact bump penetrates the insulation layer; filling a filler in the opening; and stacking a metal layer on the insulation layer. Using the method, the reliability of circuit connections between the component and the circuit patterns can be improved, and the manufacturing process can be reduced in embedding the component in the printed circuit board.

Abstract: Disclosed is a memory access control apparatus capable of writing image data in an external memory or reading the image data. The memory access control apparatus comprises a memory access control unit for storing image data in a memory by a two-dimensional array according to values of a bank, a row, and a column inside the memory where the image data is to be stored calculated on the basis of coordinate values of the image data constituting one image frame and predetermined data.

Abstract: A heat exchanger for recollecting waste heat is provided, which is configured to circulate low-temperature water into inlet and outlet water circulation units and a heat exchanger tube, so as to be heat exchanged with the waste warm water. As a result, the number of configurational elements is minimized to thereby have a simple structure and thus the temperature of the low-temperature water is efficiently heightened irrespective of an installation place of the heat exchanger. The heat exchanger for recollecting waste heat includes inlet and outlet circulation water units which are formed to have a predetermined shape so that externally incoming low-temperature water is guided, supplied and discharged, and at least one heat exchanger tube which circulates the low-temperature water between the inlet and outlet circulation units.

Abstract: An apparatus and method for transmitting header information in an ultra wide band (UWB) communication system. To protect physical layer header information from errors that may occur during transmission in the UWB communication system, a transmitter transmits the header information after encoding it with an error-correcting code, whereas a receiver decodes the encoded header information with the error-correcting code. This improves the throughput in a wireless network and also decreases the bit error rate.
