The invention relates to the recovery of the potential energy from the apron of a roller blind including driving means provided with a motor connected to autonomous supply means during the expansion or retraction phase of the apron. More particularly, during the expansion or retraction phase of the apron, the method comprises determining an energy recovery phase corresponding to a motor torque applied by the apron on the driving means. The invention also allows energy recovery without damaging the components of said blind.

The present invention pertains to the field of signal transmission systems and essentially relates to autonomous devices for transmitting digital signals as well as to remote control systems comprising the same. This invention can be used for producing digital-signal autonomous emitters comprising an efficient power-supply circuit from charge generators, such as piezoelectric or tribo-electric members or radiating sources of charged particles, that do not need to be periodically replaced or recharged unlike traditional power sources such as batteries. It is thus possible to create remote control systems for electric appliances, data collection systems as well as signaling systems while integrating emitters of remote control signals for an extended period in structures and systems not requiring any maintenance. It is further possible to create remote control systems for lighting fixtures in which the wall switches are made in the form of autonomous emitters of on/off signals for corresponding lighting fixtures. To this end, a charge generator (1) is actuated for generating a portion of the electric charges q at a high electric potential Uin, wherein said portion is supplied to the input of a converter (2). The function of this converter results in a substantial increase in the initial value of the charges q up to a value Q, as well as in the storage of said charges at the converter output at a potential Uout having a value lower than that of Uin. The operation of the unit (3) for generating and transmitting a digital signal is ensured by the power supply from the charge Q which is obtained by the conversion and is supplied to the input of said unit (3).

A portable self-contained power pack is described including a miniature internal combustion motor/alternator combination with an attached fuel supply. The electrical output from the motor/alternator is rectified and controlled to provide a DC output. The DC output is used to charge batteries and/or capacitors. The power pack is designed to be of a weight and size so that it may be carried while in use on the person of the user. The DC output and the batteries and/or capacitors are connected and power personal items. These personal items include, but are not limited to, cell phones, portable radios, laptops, stand alone computers, music and video players and recorders, personal electronic organizers, games and cordless power tools.
