Abstract: The invention relates to electrical circuits. More specifically, the invention relates to the detection whether an input wire is floating, connected to the Line or to the Neutral of an AC electric power supply. The invention uses impedances between a point of the circuit and the Input, the Line and the Neutral, and the status of the input line is determined based on the voltage at said point of the circuit, or a derivative thereof.

Abstract: The invention concerns a locking mechanism (10) comprising an indoor mechanical actuation lever (11), an outdoor mechanical actuation lever (12) and a lock clutch (13), each mechanical actuation lever being configured to switch between a closed configuration and an open configuration, wherein the lock clutch (13) is configured to take at least three positions: a first position where the lock clutch is disengaged from the indoor mechanical actuation lever and outdoor mechanical actuation lever, a second position where the lock clutch is engaged with the indoor mechanical actuation lever and outdoor mechanical actuation lever, a third position where the lock clutch is engaged with the indoor mechanical actuation lever and disengaged from the outdoor mechanical actuation lever.

Abstract: The invention concerns a controlling device (10) having terminals for connection to an electrical circuit (11) comprising: a first user device (12) energized by a first voltage power supply and configured to switch between at least an on-state and an off-state, a second user device (13) configured to be connected in series with the first device (12) and energized by a second voltage or current power supply, the controlling device (10) being configured to be connected in parallel of the first user device (12) and to: absorb a leakage current flowing through the electrical circuit (11) below a first predetermined threshold, and control the voltage or current between the terminals of the controlling device (10), so as to ensure that the second user device (13) is supplied with the second voltage or current.

Abstract: The invention concerns a multi-state device (10) comprising a communication port (13) configured to receive a stimulus from a remote control (14), a transmitter (15) of an identifying code (16) on a line-of-sight carrier, a controller (17) configured to one or more of compare an identifying code received from the remote control (14) to the identifying code (16) of the multi-state device or make the multi-state device (10) switch from one state (11) to another state (12). The invention also concerns a method for controlling a multi-state device (10) using a remote control (14).

Abstract: The invention concerns a lock mechanism (10) configured to switch between a locked state and an unlocked state, the lock mechanism being configured to cooperate with at least one identification key (11) having an identification code (12), the lock mechanism comprising a processor (15) in a power saving off-state, configured to read the identification code (12) of the at least one identification key (11) and determine if the identification code (12) is an authorized code (14) of the lock mechanism when in an activated state, an event sensor (13) configured to switch the processor (15) from the power saving off-state to the activated state if an event is detected by the event sensor (13).

Abstract: The invention concerns a locking mechanism (10) comprising an indoor mechanical actuation lever (11), an outdoor mechanical actuation lever (12) and a lock clutch (13), each mechanical actuation lever being configured to switch between a closed configuration and an open configuration, wherein the lock clutch (13) is configured to take at least three positions: a first position where the lock clutch is disengaged from the indoor mechanical actuation lever and outdoor mechanical actuation lever, a second position where the lock clutch is engaged with the indoor mechanical actuation lever and outdoor mechanical actuation lever, a third position where the lock clutch is engaged with the indoor mechanical actuation lever and disengaged from the outdoor mechanical actuation lever.
