Abstract: An EoD system for personal living activities. A current electric power value is received from a smart tap, a use state q of an appliance is estimated from the current electric power value, change of the use state is detected as an event when the use state is different from a use state of a previous time, and the type of the event and an occurrence time are stored in a memory. Following that, a first weight of the living activity by the type of the event is calculated based on an appliance function model and an elapsed time from the event occurrence time, and a second weight to each living activity corresponding to the current use state of the appliance is acquired from an appliance function model. Based on the product that is a multiplication of the first weight and the second weight, a sum of the products is calculated for each appliance, and a living activity label, in which the sum of the product values of each appliance becomes a maximum value, is estimated as a living activity label of a time.

Abstract: An on-demand control system that supplies power to electric devices based on not predetermined priorities fixed to electric devices, but based on priorities changed according to the use status of the user. The on-demand control system can control supply of power of a commercial power source in real time in response to a power request necessary for the user and controls the supply of power according to the QoL necessary for the user through daily life. The on-demand power control system is a multiple power source management system for an on-demand power control system.

Abstract: Power is supplied to electrical devices while priorities between the electrical devices are being changed according to the states of use by a user instead of predetermined fixed priorities between the electrical devices, supply of power from a commercial power source can be controlled in real time at a request for power required by the user, and supply of power meeting QoL required in user's daily life is controlled. A power manager determines power to be assigned to each electrical device by inquiring a home appliance agent of whether or not the electrical device is capable of adjusting an operating function mode set as a target of a service operation of the electrical device, and of power for the electrical device.

Abstract: A smart tap into which one or more than one power plugs can be inserted, including a voltage waveform measurement unit, a current waveform measurement unit, a communication unit, a control unit, and an arithmetic unit. The voltage waveform measurement unit and the current waveform measurement unit are units which measure a voltage waveform and a current waveform of power supplied to each of one or more home appliances via a corresponding respective power plugs connected to the home appliances. The communication unit is a unit which transmits the voltage waveform and the current waveform or a result of processing of the waveforms to a server. The control unit is a unit which controls switching of the power supplied to the home appliance and the amount of the supplied power in accordance with the control signal.

Abstract: In order to estimate behavior of a person at home from a feature and a power consumption pattern of an electrical device, an on-demand power control system of the present invention includes initial human-induced probability value estimation means that estimates a state of the electrical device, and estimates an initial value of a human-induced probability of the electrical device based on the estimated state of the electrical device, human position estimation means for calling up the initial value of the human-induced probability of the electrical device and a likelihood map of this device from a memory, performing, for all samples, a process of referring to a sample human position selected from the likelihood map and calculating a weight of the device by multiplying a human position and the human-induced probability of the device, and estimating a probability of a human position at each time point until a final time; and human-induced probability re-estimation means for performing recalculation of the human-

Abstract: A dynamic priority control apparatus of the present invention is characterized by including means that calculate a difference between instantaneous power of an initial target value and actual instantaneous power, initial target value updating means that take into account the difference, calculating priorities of electrical devices means based on electrical device property class data, and power arbitration means that determines the electrical devices to be supplied power based on the total value of the consumed power and the priorities of the electrical devices.
