According to one embodiment, a pumped-storage power generation control device includes a control section that controls at least one of the pumping input of the pumped-storage power generation facility in the pumping operation and the power output of the pumped-storage power generation facility in the power generating operation such that a value, which is obtained by a predetermined calculation using the measurement value relating to the pumping input of the pumped-storage power generation facility in the pumping operation and the measurement value relating to the power output of the pumped-storage power generation facility in the power generating operation, becomes a set target value.

Pumped-storage power generation control device and pumped-storage power generation control method

A method of detecting a position of a radio mobile station in radiocommunications, which is capable of accurately and simply finding the position of the mobile station. At a measuring point the mobile station measures the reception radio strength levels from a plurality of base stations and conveys the measurement results through the base station to a control station. The control station learns, through a neural network, the correlation between the reception radio strength levels and the position of the mobile station on the basis of the measurement results at a plurality of measuring points and the positions of the measuring points. Subsequently, when the mobile station communicates to the control station the reception radio strength levels measured at an arbitrary point, the control station estimates the position of the mobile station, causing those measurement results, on the basis of the correlation obtained through the learning.

Wireless communication system and method and system for detection of

An information acquisition proxy system which conducts mediation for information acquisition between an information accessing terminal and an information distributing server. The system comprises a user authentication section for identifying a user and an information acquisition history managing section for retaining and managing a demand for information acquisition from the information accessing terminal, with the information acquisition history managing section retaining and managing demands in units of users. Also included in the system is an additional information managing section for managing additional information for the demand said information acquisition history managing section manages. With this arrangement, an additional information is added by one user when the user has access to specific information, and hence the user can refer to the additional information at the later information access using a different information accessing terminal, thus allowing effective information access work based upon the previous access situation.

Information acquisition proxy system and information transfer managing

A wireless communication system comprises: a center unit and a plurality of terminal units, wherein the center unit includes: a transmitting portion for recurrently generating time slots and transmitting data through the set of time slots; a broadcasting control portion for respectively sending information of at least a predetermined time slot to be used out of the time slots for broadcast to the plurality of terminal units through the transmitting portion and for operating the transmitting portion to transmit the data to be broadcasted through at least the predetermined time slot; and each of the terminal unit includes: a receiving portion for receiving the data through one of time slots assigned to each of the terminal unit out of the time slots; and a broadcasting receiving control portion for receiving the information through the receiving portion and for controlling the receiving portion to receive the data to be broadcasted using the predetermined time slot with reference to the information. The center unit may broadcast the data using both time slots of upward and downward transmission and may synchronize a top of reference frame of the data including video data of moving pictures with a top of the slot for broadcasting.

Wireless communication system and wireless communication apparatus

There is disclosed a current control apparatus comprising first controllers adapted for detecting an overall or total load current to calculate distribution values for distributing a current margin with respect to an overall or total current limit value to respective air-conditioners; and second controllers adapted for respectively controlling air-conditioners so as not to exceed individual current limit values, and for carrying out an incremental correction of individual current limit values in accordance with distribution values calculated by the first controllers.

Current control apparatus for air-conditioning system

A heat pump type apparatus with an air heating mode which heats a whole space using an internal heat-exchanger, a floor heating mode which heats the floor around the space using a floor heating panel, and a combined use of both type heating. In the combined use mode, the apparatus compensates the desired preset room temperature by a specified value in response to the results of a comparison of an actual floor temperature and a desired preset floor temperature.

Heat pump type heating apparatus and control method thereof

A refrigeration cycle constitutes a closed cycle for circulating a refrigerant therein and includes at least a variable capacity compressor, an outdoor heat exchanger, an expansion valve, and an indoor heat exchanger. The indoor heat exchanger is provided with temperature sensor and an indoor fan. A floor heating panel is connected in parallel with the indoor heat exchanger. The panel is provided with a floor temperature sensor. A flow control valve is arranged in a refrigerant upstream side of the panel at a heating operation. A controller controls the compressor, the fan, and the valve in a first state at the start of a heating operation to simultaneously start air heating by the indoor heat exchanger and floor heating by the panel. The compressor, the fan, and the valve are controlled in a second state when a detection output from the room temperature sensor reaches a preset value, thereby maintaining a room temperature and increasing a floor temperature. At least one of the compressor and the valve are controlled in a third state when a detection output from the floor temperature sensor reaches a preset value, thereby maintaining the floor temperature. At least one of the compressor and the fan are controlled in a fourth state, thereby controlling the room temperature to a predetermined value.
