Abstract: The disclosure relates to an autonomous device for tracking the usage time of a generator set, capable of providing an operating time of the generator set. The module includes at least one first sensor (101) capable of measuring a first parameter representing a state of operation of said generator set (9), a data processor furnishing the characteristic information for an operating time, as a function of the first parameter, storage of the characteristic information for an operating time, and a transmitter capable of transmitting the characteristic information for an operating time to a terminal or an external server.

Abstract: A method is provided for communications in a network interconnecting at least two power generators, each power generator being connected to said network by at least one interfacing device capable of sending and receiving communications frames. The frames have at least one piece of supervision data and at least one piece of information data. The method includes an act of sending during which the same pieces of information data are sent at least twice, wherein two operations of sending frames have identical pieces of information data being separated in time by a predetermined time interval; and an act of receiving, implementing a systematic elimination of one of the frames received when two frames having identical pieces of information data have been received.

Abstract: An apparatus includes an exhaust system, a cooling system, and two or more thermoacoustic devices. A first thermoacoustic device is configured to convert heat energy from the exhaust system to amplify an acoustic wave. A second thermoacoustic device configured to convert energy in the amplified acoustic wave to an input for the cooling system. The apparatus may be incorporated or in communication with an engine or a generator.

Abstract: A generator system that includes an engine and an alternator which is driven by the engine to generate electrical power. A radiator is connected to the engine and an axial fan directs air toward the radiator to cool the radiator. A plurality of static vanes is located between the axial fan and the radiator. Each static vane includes an inner end and an outer end, the inner ends of the static vanes being joined together. The static vanes are curved in a plane orthogonal to the rotation axis in order to direct the air towards the axis, thereby counterbalancing the centrifugal forces. The static vanes may be twisted, the pitch angle increasing from 0 degree at hub to circa 45 degrees at tip. Additionally, each static vane is attached to the shroud via a third member that extends axially, thereby allowing an axial offset between shroud and static vanes.

Abstract: A method of communications in a network interconnecting at least two power generators, each power generator being connected to said network by means of at least one interfacing device capable of sending and receiving communications frames, said frames comprising at least one piece of supervision data and at least one piece of information data. The method may include a step for sending during which the same pieces of information data are sent at least twice, two operations for sending frames to be sent that comprise identical pieces of information data being separated in time by a predetermined time interval, and a step for receiving, implementing a systematic elimination of one of the frames received when two frames comprising identical pieces of information data have been received.

Abstract: A method is provided for controlling at least one power generator implementing a touch-sensitive screen on which there selectively appears a set of command buttons available at a given point in time. The method includes: determining a working context and selecting a set of command buttons available for said working context; displaying said set of available command buttons on said touch-sensitive screen; detecting an activation of one of the available command buttons, called an activated command button; performing at least one action associated with said activated command button.
