Abstract: An apparatus and method of detecting a frame synchronization signal, capable of reducing errors in data demodulation in an optical system, are provided. The frame synchronization signal detection apparatus includes a synchronization signal detector, a main frame synchronization signal generator, a sub frame synchronization signal generator, and an output unit. The synchronization signal detector detects and outputs a synchronization signal from a digital data signal. The main frame synchronization signal generator detects and outputs a first valid synchronization signal from the synchronization signal, as an internal frame synchronization signal. The main frame synchronization signal generator generates and outputs a first insertion synchronization signal, as the internal frame synchronization signal, if the first valid synchronization signal is not detected in a predetermined first time period.

Abstract: An apparatus and method for setting communication packet for a remote control between apparatuses is disclosed, which includes a communication port connected to an external apparatus by a communication bus, a communication circuit for converting signals transmitted/received by the communication port to signals appropriate for the communication bus, a memory for storing data information for communicating, and a microcomputer for controlling the communication circuit and the memory.

Abstract: A drying device and method using a humidity sensor are disclosed. The drying device includes a controller for comparing the weight and amount of moisture of the article positioned in a drying device with predetermined data and adjusting a dry time of an article on the basis of the comparison result.

Abstract: A multipurpose remote controller and method for controlling the same is disclosed, which includes a user interface unit to which a control command signal is input by a user from outside, wire and wireless transmitting/receiving units for transmitting the control command signal input from the user interface unit to corresponding apparatuses, and for receiving operation state signals of the corresponding apparatuses, a central processor for controlling the user interface and wire and wireless transmitting/receiving units, a storage storing data for controlling the central processor, and a display unit for displaying control keys under control of the central processor and for displaying operation state and results.

Abstract: Disclosed is a dental model articulator to connect the upper and the lower dental model casts. A mounting member is respectively mounted on each upper and lower cast, and a pair of elastic connecting members are connected to the mounting members. A vertical bar of the elastic connecting member has an S-type serpentine portion. The cast can smoothly move to the front, rear, left and right side by the S-type serpentine portion. A fastening member connects and disconnects the elastic connecting member and the mounting member by fastening a socket of the mounting member. A pivot member connects each elastic connecting member enabling to be pivoted. Whereby, the connecting ball of the elastic connecting member and the socket of the mounting member are connected by the fastening member, therefore the connecting ball can be connected to and disconnected from the socket.

Abstract: A communication apparatus and a method for supporting carrier sense multiple access/collision detection (CSMA/CD) are disclosed.

The apparatus includes a plurality of apparatuses having different communication protocols communicated in a bus line, and a converting apparatus connected to the plurality of apparatus for converting data input/output from an apparatus of a certain communication protocol by downloading communication protocol by Internet, or by mounting a card for converting communication protocol.

Abstract: A home networking communication system and method for communicating using the same is disclosed, which includes a main apparatus for controlling a plurality of networked peripheral apparatuses in the house by inputting a control signal from outside, and for outputting state information of the controlled peripheral apparatuses, an external apparatus for inputting control signals for controlling the plurality of peripheral apparatuses from a long distance, and web server for transmitting the control signal input from the external apparatus to the main apparatus by Internet, and for receiving the state information of the peripheral apparatuses according to the transmitted control signal, storing, monitoring the same and providing the same to the external apparatus.

Abstract: Disclosed is a network control system for home appliances that satisfies the characteristics of low-cost and high-efficiency with respect to currently used appliances adopting a low-performance microcomputer. The system is constructed to define a master/slave type communication structure with respect to the respective appliances; construct a network by connecting the appliances through the serial communication function; and enable the appliances to communicate with one another if a predetermined communication event is produced. According to the system, an optimized network for the home appliances can be implemented, and operation states of the respective appliances can be displayed through the co-operation among the appliances, thereby maximizing the user convenience.

Abstract: A method for setting a product address in a home network system is disclosed. The method includes a step for requesting a temporary address in which a network controller designates redundant addresses with a predetermined range to each product and requests an arbitrary address among the redundant address as a temporary address; a step for designating a temporary address in which each product designates an arbitrary address among the redundant addresses as a temporary address and informs to a network controller; and a step for confirming an address in which the network controller sequentially sets one of the redundant addresses for each address not doubled among informed temporary addresses from each product.

Abstract: An apparatus and a method for scrambling and descrambling data wordwise in an optical disk system are provided. The apparatus includes a bit storing means which stores at least 15 bits, and a calculating means which calculates first through fifteenth bits of the bit storing means in parallel during one clock cycle and inputs the results of the calculation back into the bit storing means.
