Provided are a method and an apparatus for searching for and acquiring information under a computing environment. The apparatus includes: at least one input device configured to receive a first query input of a first query type and a second query input of a second query type; and a controller configured to output a query input window including a first display item corresponding to the first query input and a second display item corresponding to the second query input, to automatically switch, in response to receiving the first query input, the apparatus from a first state to receive the first query input of the first query type to a second state to receive the second query input of the second query type, and to obtain a search result according to a query based on the first query input and the second query input.

Method for searching and device thereof

A method and an apparatus for automatically connecting a wireless Local Area Network (LAN) between digital devices and executing an application program based on the wireless LAN, and more particularly, an apparatus and a method for generating device information indicating attributes in a digital device and obtaining attributes of a peripheral device by analyzing device information of the peripheral device. The apparatus includes a device information generation part configured to generate device information including information about attributes by analyzing the attributes of the digital device. The apparatus also includes a device recognition part configured, when receiving device information of a peripheral device, to obtain attribute information of a device corresponding to the received device information. The apparatus further includes a controller configured to control to transmit the device information generated by the device information generation part, to the peripheral device.

Method and apparatus for connecting wireless network in a digital device

Provided are an RFID reader and a data recovery method which selectively selects only an integrity-checked phase signal, when receiving a backscattered signal of an RFID tag through an I signal path or a Q signal path, and may reduce a shadow area of a read range. The RFID reader includes a signal receiver which receives a plurality of phase signals; a symbol detector which recovers data with respect to each of the received phase signals; and a signal selector which selects a signal that satisfies a predetermined standard, from the data-recovered phase signals.

Data recovery method and apparatus for radio frequency identification

An anti-collision method is provided for a radio frequency identification (RFID) system including a reader, and two or more tags each having an ID. The anti-collision method includes transmitting an ID request value from the reader to the respective tags, the ID request value containing one or more of the codes forming the ID, receiving the ID from at least one of the tags which contain the ID request value, when a plurality of IDs collide, requesting the tags for a value representing a position of collision, and receiving the value representing the position of collision from the tags and identifying the IDs of the tags. Because collision pattern of the bits of respective IDs is recognized, and a plurality of IDs are recognized, the number of transmissions between the reader and the tags can be reduced.

Identification anti-collision method and radio frequency identification system using the same

A channel selection method for reading tag information, a channel selection apparatus of an RFID reader applying the same, and an RFID reader. A channel selection apparatus of a radio frequency identification (RFID) reader equipped within a wireless communication portable terminal, includes a channel selection unit which selects a channel to read tag information stored in an RFID tag, and a channel determination unit which, when determining that the selected channel is not used by another RFID reader, determines the selected channel to be a channel to read the tag information. Accordingly, when a plurality of RFID readers reads out the tag information from the RFID tag almost at the same time, the interference among them can be avoided.

Channel selection method for reading tag information, tag selection apparatus of radio frequency identification (RFID) reader, and RFID reader

Provided is a RFID tag with enhanced security. The tag includes a tag memory to store thereto pre-determined password information and tag data, an antenna to receive a tag data transmission request signal from an outer reader, and a tag controller to request the reader to transmit the password if the tag data transmission request signal is received, and then to transmit the tag data if the password received from the reader is identical with the pre-determined password. Accordingly, it can be prevented for a third-party, who does not know the password, to check the tag data.

RF-ID tag reading system for using password and method thereof

A portable device includes an RFID reader for detecting a tag information of an RFID tag, a memory for storing the tag information detected by the RFID reader, and a controller. When a read command for the RFID tag is input and the tag information is valid, the controller controls the RFID reader to retrieve the tag information of the memory. If the tag information is invalid, the controller controls the RFID reader to re-read the RFID tag. The controller can determine whether the tag information is valid using the time and location. Because unnecessary operation can be omitted to read tags, power consumption is reduced and tag information check time is shortened.

Portable device for caching RFID tag and method thereof

A mobile radio frequency identification (mRFID) reader having a receiving circuit is provided. The receiving circuit includes a local oscillator which generates a carrier signal at a predetermined frequency band; a mixer which mixes a tag signal received from a tag with the carrier signal, to lower a frequency of the tag signal; a phase adjusting block which adjusts a phase of the carrier signal by determining a phase of the tag signal; and a control block which processes the tag signal through a series of operations, and controls an operation of the phase adjusting block to compensate for a phase delay of the tag signal according to an output of the processed tag signal. Because the mRFID reader can be provided as small as a half size of a related art reader, a mobile communication terminal accommodating the mRFID reader can be compact-sized. Additionally, because the number of components for the receiving circuit decreases, not only the power consumption but also the unit price can be reduced.

Mobile radio frequency identification (mRFID) reader

A wireless terminal and a radio frequency identification system for providing additional information and a method of providing additional information using the wireless terminal and the radio frequency identification system. The wireless terminal includes: a tag reader reading tag data from a radio frequency identification tag; a controller generating an additional information request signal with respect to the read tag data; and a communication network interface transmitting the additional information request signal through a communication network and receiving additional information with respect to the additional information request signal. Since the controller of the wireless terminal controls the radio frequency identification reader by optimally setting the information required for determining the time point for the radio frequency identification reader tag to respond, and utilizing the stored address of the additional information providing server, the additional information can be efficiently provided.

Wireless terminal and RFID system for providing additional information and a method for providing additional information using wireless terminal and RFID system

A method for and a pre-compiling device capable of easily changing a software structure in compliance with a hardware characteristic. The pre-compiling device includes a source code scanner for scanning for a source code file, retrieving a configuration directive, analyzing a syntax of the directive, and outputting a tree of a lexical unit corresponding to the retrieved configuration directive; a core for outputting the configuration directive in a configuration state; code generation modules for outputting a configuration state output from the core as a programming language that has no correlation with a flow of the lexical unit; and programming language modules for transferring information on a comment syntax of the corresponding language to the source code scanner and the code generation modules, and receiving the programming language that has no correlation with the flow of the lexical unit outputted from the code generation modules and outputting source codes.
