  • Patent number: 7702701
    Abstract: A random bit generator and a method thereof are provided. The random bit generator includes an amplifier, a comparing circuit, an oscillator, a sampler, and a storage circuit. The amplifier amplifies a difference between input signals generated based on thermal noise. The comparing circuit compares an alternating current (AC) signal output from the amplifier with a direct current (DC) signal obtained by low-pass filtering the AC signal and outputs a signal according to the comparison result. The oscillator may be implemented with a resistor-capacitor (R-C) oscillator. The oscillator consumes lower current and occupies a smaller layout area than a voltage controlled oscillator (VCO) and outputs an oscillation signal. The sampler samples the oscillation signal output from the oscillator in response to the output signal of the comparing circuit. The storage circuit stores an output signal of the sampler in response to a clock signal.

  • Patent number: 7555913
    Abstract: A method for controlling multiple compressors for use in an airconditioner is disclosed. In the airconditioner having N compressors, the method sequentially and equally operates the N compressors using a two-dimensional matrix which prevents only a specific compressor from among the N compressors from being repeatedly operated, arranges rows and columns of the two-dimensional matrix to allow all compressors to be alternately operated according to the number of operating compressors from among all compressors, and stochastically operates and stops the N compressors using the two-dimensional matrix. As a result, the method controls the N compressors to be equally operated without overlapping operation times of the N compressors, and alleviates fatigue of the compressors, resulting in equally longer lifetimes of the N compressors.

    Abstract: An air conditioner is disclosed which includes a pressurizer for pressurizing a suction-side refrigerant sucked into a compressor, and an auxiliary condenser for condensing a discharge-side refrigerant discharged out of the compressor. Accordingly, it is possible to raise the evaporation pressure of the suction-side refrigerant sucked into the compressor, and to reduce the condensation pressure of the discharge-side refrigerant discharged out of the compressor. As a result, the difference between the suction and discharge pressures of the compressor can be reduced, so that a reduction in compression load can be achieved. Thus, a reduction in power consumption can be achieved.
