    Abstract: A cylindrical illumination confocal spectroscopy system has a fluidic device having a fluid channel defined therein, an objective lens unit arranged proximate the fluidic device, an illumination system in optical communication with the objective lens unit to provide light to illuminate a sample through the objective lens unit, and a detection system in optical communication with the objective lens unit to receive at least a portion of light that passes through the objective lens unit from the sample. The illumination system includes a beam-shaping lens unit constructed and arranged to provide a substantially planar illumination beam that subtends across, and is longer than, a lateral dimension of the fluid channel, the substantially planar illumination beam having a diffraction limited thickness in a direction substantially orthogonal to the lateral dimension of the fluid channel. The substantially planar illumination beam incident upon the fluidic device has a width that is substantially longer than the lateral dimension of the fluid channel such that the substantially planar illumination beam has an illumination intensity that is uniform across the lateral dimension of the fluid channel to within ±10%. The detection system comprises an aperture stop defining a substantially rectangular aperture having a longitudinal dimension and a transverse dimension. The aperture stop is arranged so that the substantially rectangular aperture is confocal with an illuminated portion of the fluid channel such that the transverse dimension of the substantially rectangular aperture substantially subtends the lateral dimension of the fluid channel without extending substantially beyond the fluid channel and allows light to pass from only a uniform excitation region while occluding light from outside the uniform excitation region, and the lateral dimension of the substantially rectangular aperture substantially matches the diffraction limited thickness of the planar illumination beam.

    Abstract: A miniaturized dual-balanced mixer circuit based on a trifilar layout architecture is proposed, which is designed for use to provide a frequency mixing function for millimeter wave (MMW) signals, and which features a downsized circuit layout architecture that allows IC implementation to be more miniaturized than the conventional star-type dual-balanced mixer (DBM). The proposed miniaturized dual-balanced mixer circuit is distinguished from the conventional star-type DBM particularly in the use of a trifilar layout architecture for the layout of two balun circuit units. This feature allows the required layout area to be only about 20% of that of the conventional star-type DBM.

    Abstract: A method for removing ICI for a received symbol is provided. Firstly, a transmitted symbol is received via a wireless channel within a symbol time so as to obtain the received symbol. The transmitted symbol includes P identical original partial data, wherein P is a positive integer larger than 1. The received symbol includes P received partial data corresponding to the original partial data, respectively. Next, on a time domain at least two of the P received partial data are copied so as to obtain at least two copied partial data. Each copied partial data includes P copies of its corresponding received partial data. After that, an estimated ICI of the time domain is determined according to the product of a predetermined constant array and the difference between the copied partial data. Afterwards, the estimated ICI is subtracted from the received symbol so as to obtain an output symbol.
