Abstract: Disclosed herein are a water supply device, and a steam supply device and a cooking appliance comprising the same. The water supply device comprises a slider being accommodated in a housing the front surface of which is open, in a way that the slider is movable in a front-rear direction, and a water tank being installed in the housing in a way that the water tank comes in and out of the housing in the front-rear direction and connecting to the slider to move forward together with the slider, and the slider is provided apart from the water tank.

Abstract: A lighting assembly includes at least one light source array provided in a housing and a light scattering primary transmissive optical element having at least one focal region positioned substantially parallel or concentric with the light source array. Lens features of the optical element may include a Fresnel lens pattern to produce at least one focal region. An auxiliary transmissive optical element may be provided to further control light distribution and brightness uniformity.

Abstract: A processor for performing a Fast Fourier Transform and/or an Inverse Fast Fourier Transform of a complex input signal comprises a first stage for passing the input signal to a second stage when a Fast Fourier Transform procedure is to be performed and for swapping the real and imaginary components of the complex input signal before passing the signal to the second stage if an Inverse Fast Fourier Transform procedure is to be performed. The second stage has first and second radix-4 butterfly elements. A third stage is arranged to switch between first and second operating modes, the second operating mode being for processing a complex conjugate symmetrical input signal. A fourth stage has a plurality of processing units, one or more of the processing units comprising a radix-2 pipelined Fast Fourier Transform processor.

Abstract: A method for demapping dual carrier modulated COFDM signals comprises normalizing an estimated channel state information signal to obtain a normalized channel state information signal, determining a Y-domain weighting factor from the normalized channel state information signal, determining an X-domain weighting factor from the normalized channel state information signal, performing equalization on a received data OFDM signal to obtain an equalized data signal, weighting an equalized data signal using the Y-domain weighting factor and the X-domain weighting factor to generate a weighted input signal of a demapper and performing linear demapping of the weighted input signal in the demapper. There is also disclosed an apparatus for demapping dual carrier modulated COFDM signals and a receiver comprising such an apparatus.

Abstract: A method and system for providing highly accurate characterizations of waveform representations of heart function, such as QRS complexes, where such waveform representations are derived from electrocardiographic measurements. The method and system accomplish their objects via the following. One or more signals indicative of heart function are measured and sampled. One or more signal quality indexes are calculated for each of the measured and sampled one or more signals. The signal quality indexes are calculated by dividing a maximum sample value for each one or more measured and sampled signal by a calculated divisor. One or more weighting factors, dependent upon the calculated signal quality index of each of the one or more measured and sampled signals are calculated. And, a waveform representation composed of each of the one or more measured and sampled signals indicative of heart function multiplied by its calculated weighting factor is created.
