Abstract: Provided is a heater for an aerosol-generating device including a first electrically conductive pattern configured to perform heating and a second electrically conductive pattern arranged in parallel with the first electrically conductive pattern. The first electrically conductive pattern and/or the second electrically conductive pattern may include a material having a relatively small resistance temperature coefficient. Accordingly, a temperature increase rate of the heater may be greatly improved.

Abstract: The present invention relates to a solar panel to which a high-damping stacked reinforcement part is applied and, more specifically, to a solar panel to which a high-damping stacked reinforcement part is applied, comprising: a power generation unit for generating electrical energy; a coupling part to which the power generation unit is coupled, and which has a circuit formed therein; and a reinforcement part for reinforcing the rigidity of the coupling part and damping vibration to be transmitted, and thus the present invention can prevent the power generation unit from being damaged by vibration, or the solar panel from inducing wobbling of a satellite by failing to damp the vibration.

Abstract: A network system is provided. The network system includes: at least one component selected from an energy receiving unit receiving energy and an energy management unit managing the energy receiving unit. The energy receiving unit or the energy management unit receives energy rate related information; an energy usage amount or a usage rate of when the component is controlled on the basis of at least the energy rate related information is less than that of when the component is controlled without the basis of at least energy rate related information; if the energy rate related information is high cost information, a function of one component constituting the energy receiving unit is limited; and an operating time or an output of the energy receiving unit is adjusted in correspondence to the limited function of one component.
