Abstract:
A data modular based on Gaussian minimum shift keying (GMSK) modulation and a data transmitter including the same in which the data modulator includes a read-only memory (ROM) table storing GMSK modulation data with respect to information bits; a low-pass filter filtering first GMSK modulation data, which is output from the ROM table based on a predetermined input bitstream, and outputting second GMSK modulation data; and a multiplexer selecting and outputting the first GMSK modulation data or the second GMSK modulation data based on a predetermined control signal. The data modulator selectively filters a GMSK modulation signal according to a channel state, thereby effectively controlling trade-off between inter-symbol interference and adjacent channel interference according the channel state.
Abstract:
A light-emitting element that improves reliability and manufacturing efficiency is presented. The light-emitting element includes a first electrode, a bank, a light-emitting layer and a second electrode. The first electrode is formed on a base substrate. The bank is formed on a part of the first electrode that is in a light-emitting area. The bank has a first thickness. The light-emitting layer is formed on the first electrode of the light-emitting area. The second electrode is formed on the light-emitting layer. The second electrode has a second thickness that is thicker than the first thickness of the bank. Thus, the second electrode is thicker than the bank.
Abstract:
A virtual emulation module of a subsystem based on a virtual platform includes a virtual core and a virtual program code including a set of functions. The virtual core is realized using a high-level language and corresponds to a core of the subsystem to be realized onto a system-on-chip (SOC). The set of functions of the virtual core are realized using the high-level language independent of the core of the subsystem. The subsystem to be realized onto the SOC may correspond to a microcontroller unit (MCU) subsystem or to a digital signal processor (DSP) subsystem. The high-level language realizing the virtual core and the functions of the virtual program code may be C-language.
Abstract:
A display panel for an organic light emitting display including a plurality of anode electrodes and a cathode electrode that is supplied with a predetermined voltage and includes a first portion facing the anode electrodes and a second portion receiving the predetermined voltage and having a different cross section than the first portion. A plurality of light emitting members is arranged between the anode electrodes and the cathode electrode, and a conductive line transmits the predetermined voltage and contacts the second portion of the cathode electrode.
Abstract:
An apparatus includes a drop unit, a transfer unit and a position adjusting unit. The drop unit drops droplets of an organic material. The transfer unit transfers the drop unit along a first direction. The position adjusting unit is interposed between the drop unit and the transfer unit to adjust a position of the drop unit. Therefore, the apparatus of dropping the organic material has a small size and may drop droplets of the organic material onto an accurate position. Furthermore, the transfer unit moves the drop unit quickly, and the position adjusting unit adjusts the position of the drop unit accurately. Therefore, a time difference for drying the organic material injected into a cavity is reduced.
Abstract:
In an apparatus of forming a thin film, the apparatus has a printing chamber that forms a thin film on a substrate. The apparatus has at least two drying chambers that receive the substrate on which the thin film is formed and dry the thin film on the substrate. The two drying chambers may be independently controlled. Accordingly, the apparatus may reduce process time for forming the thin film without contamination of the substrate.
Abstract:
A mechanochemical process for producing fine WC/Co composite powder which is so small in WC grain size and in mean free path, and contains such a uniform distribution of WC and Co that its hard metal is superior in strength, compressive strength, TRS and wear resistance and considerably free of impurities. The method comprises the steps of drying an ammonium metatungstate--Co(NO.sub.3).sub.2 solution in a spray dry manner to give initial powder of porous spheroids or in a common manner to give a cake of initial powder, removing the salts and humidity from the initial powder by a thermal treatment, mixing and milling the desalted initial powder with carbon black, and subjecting the mixed powder to reduction/carburization in a reactor.
Abstract:
Disclosed is an LED lighting apparatus equipped with a high-efficiency power supply, capable of representing high power efficiency even in a low-power LED lighting apparatus by recycling a surplus voltage to charge a condenser, which supplies power to the controller, with the surplus voltage if the surplus voltage is generated from an LED acting as a load after a rectified voltage supplied to the LED has been consumed in the LED according to a design value.
Abstract:
Disclosed is an active constant power supply apparatus, which rectifies power having various intensities and frequencies without using a high capacity condenser for a smoothing circuit which degrades the power factor of a circuit, and supplies constant power to a load. The active constant power supply apparatus includes an AC power supplier for supplying AC power; a rectifying circuit which receives AC power from the AC power supply unit and rectifies the received power; a driving coil connected in series to the load receiving power from the rectifying circuit; a power switch which switches the current passing through the driving coil and the load on/off; a pulse-type driving signal generator connected to a gate terminal of the power switch to control the switching on/off operation of the power switch; a turn-off decider which generates a turn-off signal when the current flowing along the driving coil has a value higher than the designed value, so as to turn off the power switch; and a pulse width controller which measures the control period ranging from the switch-on time of the driving signal generator to the switch-off time of the turn-off decider, and controls the driving pulse width of the driving signal generator such that the driving pulse width coincides with the control period.
