Abstract: An apparatus for use with a liquid supply pipeline, for transforming energy of liquid passing therethrough into electrical energy, comprising: a housing configured to be received within the pipeline and having a liquid inlet and a liquid outlet defining a flow direction therebetween, at least one current generator including a rotor supported by the housing and having a shaft and a plurality of vanes attached thereto, the shaft extending in the housing along the flow direction allowing rotation of the vanes by liquid passing through the generator, and a stator associated with the rotor for producing electrical signals corresponding to the rotation of the rotor, and a power storage mean to which the at least one current generator is electrically connected, for receiving the electrical signals.

Abstract: A liquid supply measuring apparatus is disclosed. The provided apparatus is comprised of a housing to be serially installed to a liquid passage in a way that the supplying liquid passes through the housing; a turbine, the turbine is installed inside the housing, wherein the turbine is spin by the passing liquid; a generator, the generator is pivotally or geared joined to the turbine and supplies electrical power according to the turbine's spin; and a controller, capable to calculate the supplied liquid in a way of integrating the supplied electrical power in a time sequence.

Abstract: A garden-controller system is disclosed. The system is built up from a plurality of area-controllers, a garden-controller that is located in each controlled garden in order to control the area-controllers in its' garden and a dedicated software installed on a computing means or in a dedicated web site on the Internet. Each of these area-controllers is programmed to operate and control the needed tasks in the area where the area-controller is located. The program can be updated and/or modified by the garden-controller. The system and its' parts capable to communicate via any communication infrastructure including the Internet.
