Abstract:
A voice assistance device (10) for home automation applications comprises a microphone (18) which is connected to a first amplifier (19), a loudspeaker (20) which is connected to a second amplifier (22), a communications interface (24) for connection to a data communications network, a microprocessor (12) which is programmed to sample the audio signal of the microphone (18) and transmit it, through the communications interface (24), over the data communications network for subsequent processing, as well as to receive audio streams from the data communications network in digital format, convert them to analog format, and play them on the loudspeaker (20), and an electric power supply module (28). The device (10) is enclosed in a box-like fixture (32) which can be inserted and retained in a module-supporting frame (34) for wall-mounted electrical boxes (36), and is provided with a power supply terminal strip (M2) for the connection of the electric power supply module (28) to a domestic mains electricity supply.
Abstract:
The device comprises: a pair of superimposed metallic laminae (17-17'), the chip-card (11) being arranged therebetween; the laminae are arranged inside the slot (13) of the reader (10) so that they are adjacent to the set (14) of the card reading contacts but physically separated therefrom; an electronic switch (19) for disconnecting, under the control of a microprocessor, the reading contacts (14) from the reading circuits (16) and for periodically connecting them to an oscillator (20) that generates a test signal (st), which is picked up by the laminae (17-17'); and a detector circuit (18) connected to the laminae and adapted to detect the signal (si) induced thereon so as to provide a useful voltage signal (sv) that is significantly increased above a preset threshold when the chip-card has leads that connect, for fraudulent purposes, the laminae contacts (12) of the chip of the card to an apparatus arranged outside the reader.
Abstract:
A coin and token selective storing device comprises a plurality of static compartments (15) for respective individual coins, extending from a channel (19) defining, on a planar support, a falling coin path, and arranged side by side along at least one row, and each comprising an entry opening (15a) controlled by first actuated flaps (20) for deflecting the coins and closing the opening and an exit opening (25) controlled by second actuated flaps exclusively for closure, a plurality of bistable relays being associated with the first and second flaps of the compartments in order to move, upon a programmed actuation, each flap to a stable closure position or respectively to a coin passage stable position.
Abstract:
A microphone (4) and a loudspeaker (5) are connected to processing means (7, 12) provided with connection means (8) for communicating bidirectionally with an external unit of the system. A switching device (28) functionally interposed between the microphone (4) and the processing means (7, 12) can be switched between a first position, in which the microphone (4) is physically disconnected from a communication interface (24) for connection to a computer network, and is connected to the connection means (8) via the processing means (7, 12), and a second position, in which the microphone (4) is connected to the communication interface (24) via a respective amplifier (32) and the processing means (7, 12). The processing means (7, 12) are programmed to sample the audio signal of the microphone (4), when the switching device (28) is in the second position, and transmit it over the computer network via the communication interface (24) for subsequent processing, as well as to receive from the computer network audio streams in digital format, convert them to analog format, and play them back on the loudspeaker (5).
