Abstract: An equipment can function according to a plurality of operating modes that include a deep standby mode in which the energy consumption is minimum, an active mode in which the energy consumption is maximum and a light standby mode in which the energy consumption is intermediate between deep standby and active mode, a change from the deep standby mode to the active mode being slower than a change from the light standby mode to the active mode. The method enables an electricity meter supervising an electricity network to which an item of equipment is connected to control the change of said equipment to light standby mode. To do this, the meter implements a procedure for the detection of human presence based on an analysis of the electrical consumption in the electricity network and activates the light standby mode of the equipment when a user is detected.

Abstract: The composition disclosed is a pseudo-thermosetting neutralized chitosan composition, neutralized with an hydroxylated base, forming a phosphate-free transparent hydrogel at a temperature higher than 5° C. Said composition contains a homogeneously reacetylated chitosan derived from a chitosan having a deacetylation degree of 80-90%, having a molecular weight of not smaller than 200 kDa and a deacetylation degree of 30-60%, and may further contain a diol. Said composition may be used as a drug delivery system.

Abstract: In an antenna for television, radio or the like, including antenna elements radiating from a boom, a self-locking hinge intermediate the ends of an antenna element for permitting folding of the element for convenient boxing, or the like and for permitting unfolding and elongation of the element for use; the hinge comprising a hinge connection that is spaced from one side of the element and a snap latch that is spaced from the opposite side of the element, thereby rigidifying and strengthening the hinge connection.
