Abstract: Method for communicating information by infrared radiation between a control command transmitter for a motorized product for closure, privacy or solar protection in a building and a control command receiver, comprising the transmission of a communication frame including: a preamble signal consisting of the repetition of pulses of a first type, and a data signal, the data being translated into the form of pulses of a second type, wherein the preamble signal and the data signal are modulated at the same frequency and wherein the data signal is separated from the preamble signal by a signal-free period having a duration of greater than twice the maximum duration separating two successive pulses of the second type.

Abstract: A method for adjusting the residual light gap between slats of a motorized blind when oriented in a set closed position of the blind, where at least one closed position of the slats is set by automatic detection using detecting means, comprising the following steps: adjusting a detection criterion of the detecting means, performing anew automatic detection of the closed position with adjusted detection criterion, recording the new value of the detection criterion.

Abstract: A method of operation of an electric self-powered home automation installation (10) comprising an actuator (1) allowing the movement of a movable screen (2) and a bipolar electric source (6), the actuator comprising a motor (3) for driving the movable screen and a means (4) for controlling the motor supply, the bipolar electric source comprising an in-situ rechargeable electric source (62, 63) and a non rechargeable electric source (61), the operation method comprising a first operation mode, wherein: the actuator is supplied only with the in-situ rechargeable electric source (62, 63) as long as the control means does not cause the motor to be supplied, whereas the actuator is at least supplied by the non rechargeable electric source (61) when the control means causes the motor to be supplied.
