Abstract: A management device includes a potential usable power calculator that computes a measurement value or an estimated value for a potential usable power which is the amount of power available when the power consumption of an electrical appliance and a potential feed-in amount that can be sold are excluded from the power output from the solar power device; a planned usage determination unit that identifies a planned usage time that a user plans to use a designated appliance; an effective time determination unit that identifies a continuous effective time when a physical quantity representing a state that changes due to the designated appliance using the potential usable power is within a range that is effective for a user; and a scheduler that creates an operation schedule indicating at least an operation start time for the designated appliance on the basis of the planned usage time and the continuous effective time.

Abstract: A management device includes a surplus power calculator configured to compute a measurement value or an estimated value for a surplus power which is power output from the power generator excluding the power consumption of the electrical appliance; and a scheduler configured to create an operation schedule for a designated appliance scheduled to operate during a period different from a surplus power period when the surplus power is available so that the designated appliance uses the surplus power during the surplus power period to operate; the scheduler also configured to shift the operation period of the designated appliance when a potential usable power is greater than an increment in the power consumption resulting due to shifting the operation period of the designated appliance, where the potential usable power is the surplus power with a potential feed-in power excluded therefrom.

Abstract: A vibration power generator configured to generate power by displacement between an electret group having a plurality of electrets and an electrode group having a plurality of electrodes in a relative movement direction in response to an external vibration, includes a casing in which the electret group and the electrode group are disposed, a fixed member in which one of the electret group and the electrode group is disposed, the fixed member being fixed to a side of the casing, and a movable member in which the other of the electret group and the electrode group is disposed. The movable member is disposed in the casing such that the movable member is relatively movable in response to the external vibration while opposed to the fixed member.

Abstract: A vibration power generator in which an electret group including a plurality of electrets and an electrode group including a plurality of electrodes are displaced in a relative movement direction by an external vibration, and vibration power generation is thereby performed, has a housing portion that accommodates the electret group and the electrode group, a fixed member that is fixed to a bottom surface side of the housing portion and has one of the electret group and the electrode group as a fixed member-side power generation element, a movable member that is accommodated in the housing portion so as to be capable of relative movement by the external vibration while opposing the fixed member, and has the other of the electret group and the electrode group as a movable member-side power generation element, and a plurality of support members.

Abstract: A vibration energy detection apparatus has a vibration power generator installed in an inspection object that converts vibration energy generated in the inspection object into power, an electric storage unit that stores generated power of the vibration power generator, a voltage monitor that monitors a storage voltage of the electric storage unit, a discharge controller that discharges electric storage energy of the electric storage unit when the storage voltage of the electric storage unit exceeds a predetermined storage voltage, and a vibration energy calculator that calculates the vibration energy generated in the inspection object based on the number of formation times of an electric storage state of the electric storage unit. The electric storage state is continuously or intermittently formed by the discharge by the discharge controller.

Abstract: An electrostatic induction power generator includes a spherical member for making a distance between surfaces of a first substrate and a second substrate facing each other constant. A housing is provided with a first reference surface to which a surface of the second substrate facing the first substrate is fixed and which is a positioning reference for the second substrate with respect to the surface facing the first substrate in a vertical direction, and a second reference surface with which the spherical member is slidably in contact and which is a positioning reference for the spherical member with respect to the surface facing the first substrate in the vertical direction. The spherical member is slidably in contact with a surface of the first substrate facing the second substrate.
