    摘要: A receiver to detect pulses on a home phone wiring network using envelope detection. The receiver comprises an integrating capacitor charged by a first current source responsive to a differential signal propagated on the wiring network, and discharged by a FET in combination with a second current source. The combination of the FET and the second current source allows the capacitor to be quickly discharged in a smooth fashion. An application of this receiver is for a PHY according to the Home Phoneline Networking Alliance.

    摘要: The invention relates to a magnetic-card operated mechanism for closing and opening safes and to safes embodying it. The mechanism is powered by batteries and comprises means for reading a magnetic card, an electronic activating circuit and a locking mechanism, and is provided with electronic means for permanently storing information, with means for changing the power drawn from the batteries between at least one high level and one low level, with means for checking the correctness of the card code and of its reading, and with means for enabling the card to actuate the mechanism only if the result of the check is positive. The mechanism comprises an electrically actuated locking device powered by an electric motor and may also comprise additional manual locking means, which are blocked in the locking position or are released therefrom by the electrically actuated device. The said high power level corresponds to the power required by the electric motor and any other accessory devices, while said low power level corresponds to the tension required to prevent erasure of information contained in the volatile memories that are part of the electronic activating circuit. This assures a life-period in the order of a number of years between battery changes. An emergency unlocking device is provided, to permit opening the safe in case of failure of the normal unlocking means, said emergency device being enclosed in the safe door and only operative if it is manually actuated through a perforation in said door.
