Abstract:
In an air conditioning system, a first controller converts the communication method of an external command inputted into the second controller and transmits the same to an air conditioner. Further, the first controller displays operating information of the air conditioner. Accordingly, the structure of the air conditioning system is simplified, and installation costs are reduced.
Abstract:
Disclosed is a stock account/order/market price inquiry service method using a mobile terminal that is able to perform a stock account/order/market price inquiry service through a mobile terminal using a stock chip. A stock account/order/market price inquiry service method comprising the steps of: (1) displaying a lower menu page on a mobile terminal of the stock account/order service after a PIN authentication; (2) generating an account/order service request message on the basis of stock chip information read from a stock chip and service request information corresponding to the lower menu and then transmitting the same to a relay server; and (3) receiving a service response message corresponding to service request message from the relay server and displaying the same on the screen of a mobile terminal.
Abstract:
This invention relates to a bismuth molybdate catalyst, a preparation method thereof, and a method of preparing 1,3-butadiene using the same, and to a bismuth molybdate catalyst, a preparation method thereof, and a method of preparing 1,3-butadiene using the same, in which 1,3-butadiene can be prepared through oxidative dehydrogenation directly using a C4 mixture including n-butene and n-butane as a reactant in the presence of a mixed-phase bismuth molybdate catalyst including α-bismuth molybdate (Bi2Mo3On) and γ-bismuth molybdate (Bi2MoO6). According to this invention, the C4 raffinate, containing many impurities, is used as a reactant, without an additional n-butane separation process, thus obtaining 1,3-butadiene at high yield. Unlike complicated multicomponent-based metal oxides, the catalyst of the invention has simple constituents and synthesis routes, and can be easily formed through physical mixing, and thus is very advantageous in assuring reproducibility and can be directly applied to commercial processes.
Abstract:
There is provided a MTCMOS flip-flop configured to operate at high speed and to reduce leakage current while realizing a retention function in a sleep mode. The MTCMOS flip-flop may include a signal generator adapted to output an internal clock signal or a sleep mode control signal based on changes in a retention signal and an external clock signal, a master latch adapted to latch an input signal and to output a master latch output signal based on the internal clock signal, and a slave latch connected to an actual ground and adapted to latch the master latch signal, to output a slave latch output signal under control of the internal clock signal, and to maintain the latched signal under control of the sleep mode control signal in the sleep mode.

Abstract:
An organic aluminum precursor includes aluminum as a central metal, and borohydride and trimethylamine as ligands. In a method of forming an aluminum layer or wire, the organic aluminum presursor is introduced onto a substrate, and then thermally decomposed. The aluminum decomposed from the organic aluminum precursor is deposited on the substrate.
Abstract:
A method and apparatus for providing a service using location information in a mobile communication terminal are provided. The method includes identifying service area information and operation information allocated to each corresponding area information from a Subscriber Identification Mobile (SIM) card, transmitting operation information allocated to area information representing a current location of the terminal to a service provider server, and receiving a service corresponding to the operation information from the service provider server.
Abstract:
In some embodiments, a device includes a multiple-input multiple-output (“MIMO”) decoder module coupled to a first log-likelihood-ratio (“LLR”) computing unit. The decoder module includes at least one processing unit and at least one sorting unit. The decoder module preferably uses a K-best breadth-first search method to decode data from MIMO sources. In some embodiments, a method includes receiving data representing a vector of receive signal samples detected by multiple receive transceivers. The method further includes performing a K-best breadth-first search on the data to obtain an estimated constellation point. The method further includes providing a user data stream based at least in part on the estimated constellation point.
Abstract:
The present invention relates to a tag anti-collision Radio Frequency Identification (RFID) system and a method for tag identification. The method for tag identification consists of a first step of initializing a queue (Q) field and storing a prefix of a candidate queue (CQ) field in the queue field; a second step of transmitting a query including the prefix stored in the queue field to the RFID tags, and deleting the transmitted prefix from the queue field; a third step of inserting a prefix, in which prefixes 0 and 1 are inserted into a rear portion of a prefix of a previously transmitted query, into the queue field if two or more tags respond to the previously transmitted prefix and, therefore, the tags cannot be identified, and inserting the prefix of the previously transmitted query into the candidate queue field and deleting an unnecessary prefix stored in the candidate queue if there is no response or only one tag responds with respect to the previously transmitted prefix; and a fourth step of determining whether a prefix stored in the queue field exists, and returning to the second step if there is a prefix stored in the queue field.
