WIRELESSLY-POWERED ELECTRICALLY-OPERATED DEVICE
First Claim
1. A wirelessly-powered electrically-operated device comprising a wave receiving portion receiving wave motion that is transmitted wirelessly, an energy extracting portion extracting, as energy, the wave motion received by the wave receiving portion, an electricity storing portion for storing the energy extracted by the energy extracting portion, and a driving portion that is driven by receiving a supply of energy that is stored in the electricity storing portion, comprising:
- a work quantity forecasting device defining, as an operating period for the driving portion, a specific period that is set in advance, and defining, prior to entering into that operating period, the operating period as an operating period for forecasting, to forecast the total amount of work of the driving portion in the operating period for forecasting;
a total required energy forecasting device forecasting the total required energy in the device for the operating period for forecasting based on the total amount of work of the driving portion forecasted by the work quantity forecasting device;
a supplyable energy calculator summing, prior to entering into the operating period for forecasting, an amount of energy that remains, at that time, in the electricity storing portion and an estimated energy to be extracted from the wave motion by the energy extracting portion between the current time and the time of the end of the operating period for forecasting, to calculate the summed energies as the supplyable energy that can be supplied during the operating period for forecasting;
an energy comparing device comparing the total required energy for the operating period for forecasting, forecasted by the total required energy forecasting device, and the supplyable energy for the operating period for forecasting, calculated by the supplyable energy calculator; and
a notifying device providing notification of information based on the comparison results by the energy comparing device.

Abstract
An operating period for a driving portion is defined. Prior to entering the operating period, it is defined as a forecasting operating period, the total amount of work of the driving portion for the forecasting operating period and a total required DC electric energy A for the device during the forecasting operating period are forecasted. Prior to entering into the forecasting operating period, a stored DC electric energy B, and an estimated DC electric energy C to be extracted from a wireless electric energy supply between the current time and the time of the end of the forecasting operating period are summed as a supplyable DC electric energy D for the period. The total required DC electric energy A for the forecasting operating period and the supplyable DC electric energy D are compared, and if D<A, the wireless electric energy supply is requested to increase its power distribution.
