Abstract: The radio-frequency signal frequency conversion device generates intermediate complex signals (IF) for a correlation stage of a low power RF receiver. In order to do this, the device includes a first selective pass-band filter for filtering radio-frequency signals picked up by an antenna. A frequency synthesizer generates first and second high frequency signals, wherein the frequency of the first signals is higher than the frequency of the second signals. This synthesizer receives reference signals from an oscillator unit. A first mixer unit mixes the radio-frequency signals with the first signals in order to generate frequency-converted signals. A second pass-band filter filters the signals from the first mixer unit, and provides signals to a second mixer unit to mix them with the second high frequency signals. Finally, shaping means for the signals provided by the second mixer unit generate the intermediate signals.

Abstract: The invention concerns a lunar month display mechanism, for a lunisolar calendar mechanism. The mechanism includes concentrically a plate, which determines the position of the additional month in the bissextile years. The plate is provided with a hand associated with a scale of twelve months and carries a planetary wheel permanently braked by a restraining device. The drive wheel, driven over one twelfth of a revolution at each new moon, meshes with the planetary wheel and moves the plate and hand forward. At the start of a bissextile month, the stop fingerforces the wheel to rotate overcoming the force of the restraining device while the drive wheel is rotating, such that the hand remains close to the number of the preceding month. The position of the stop finger is determined by a year cam. This mechanism can be used in particular in a Chinese calendar display.
