Abstract: A step-by-step electric relay structure of a bistable type, comprising a mechanical part and an electric part, the mechanical part comprising push-button means to be operated by a user and the electric part comprising coil means, capacitor means, resistor means and diode means operatively interconnected to one another, the coil means comprising either two coils coupled in parallel to one another or a single coil polarized or biased with two polarities, thereby, as the push-button means are operated by the user to provide a switching or exchanging of at least a contact of the relay structure, either one of the two coils is shorted or the two polarities of the single coil are mutually reversed, thereby providing the electric relay structure with a logic SET function and a logic RESET function.

Abstract: A control unit for controlling electrical apparatus. The control unit has (i) a control device which may be wall-mounted; (ii) an actuation plate which may be secured to the control device and comprises a cover surface which is at least partially transparent; (iii) a sensor member for detecting when a user's finger or another body comes into contact with a touch zone; and (iv) a control designed to control the electrical apparatus according to a specific function following detection of the contact action. The control device comprises a switching device associated with the touch zone through the control in such a way that the actuation of the switching device controls the electrical apparatus according to the same function associated with the touch zone.

Abstract: A control unit for electrical apparatus, of the type comprising a control device which may be wall-mounted and an actuation plate which may be secured thereto. The actuation plate comprises a cover surface and a sensor member for detecting when a user's finger comes into contact. The control device comprises a base structure, a terminal block for the electrical connection of the control unit to the electrical apparatus, and an abutment member comprising an edge designed to abut on an inner surface of the actuation plate opposite the cover surface, the abutment member being connected to the base structure in such a way as to enable the edge at least to move in translation in a fastening direction of the actuation plate on the control device.

Abstract: Electrical device with axial control, such as switch, double-pole switch, toggle switch, inverter or the like, including a box-like containment structure (20) in insulating material, in which are housed: at least two connection terminals (31, 32), at least one fixed electrical contact (35) connected to one (31) of the connection terminals, at least one rocker arm element (36) carrying at least one mobile electrical contact (37) and connected electrically to another (32) of the connection terminals, and an axial actuation member (70) kinematically connected via a first oscillating support (50) to the rocker arm element (36), so as to make it oscillate between two predetermined stable positions, wherein on the first oscillating support (50) acts a second oscillating support (60) which is made to oscillate in one direction or in the other at each actuation of the axial actuation member (70).

Abstract: The present invention relates to a method of modulating development of a cell. The method includes the step of introducing into the cell a nucleic acid with the capacity to modulate development of the cell, the nucleic acid including a target site for binding of a microRNA, wherein the activity and/or concentration of the microRNA in the cell results in a level of activity and/or concentration of the nucleic acid in the cell sufficient to modulate development of the cell.

Abstract: A bus modem for building and industrial electrical systems comprises a module (100) which comprises a pair of input pins (1, 2) destined to be connected to the bus and a pair of output pins (9, 10) destined to be connected to the electrical circuit of a device to be connected to the bus. The module (100) further comprises a voltage control circuit (3) able to take voltage from said bus and to control the voltage (VASB) on a capacitor (C1) disposed at the terminals of said output pins (9, 10), and a transmission control circuit (5) able to control an electronic switch (7) which controls a current limiting circuit (8) able to limit the current on the bus, during transmission of signals from the bus to the devices connected to the bus and vice versa.

Abstract: A mechanism is described for compression actuation, by means of a rocking key, of electric controls such as switches, change-over switches, selector switches and the like, in which there are provided at least one fixed contact (12) and one movable contact (11), carried by a movable anchor (10), rotatively actuated to bring the movable contact (11) towards or away from the fixed contact (12), through a pin (21) operated by the rocking key (5) and pushed against said movable anchor by a compression spring (22), where the pin acts against the movable anchor (10) by means of an articulated head or joint (38) shaped like a fork, so that the two branches of the fork arrange themselves on corresponding areas (45) of the anchor that are substantially symmetrical with respect to its center (46).
