  • Patent number: 6140964
    Abstract: 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.

  • Patent number: 5170936
    Abstract: 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.

  • Patent number: 5088646
    Abstract: 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.
