  • Patent number: 10691472
    Abstract: The present invention has an object of providing a user interface execution apparatus and a user interface designing apparatus which can estimate the maximum size of a storage area for storing data to be prefetched when a user interface is designed and can present updated data to the user even when the prefetched data is updated after the prefetch. A user interface execution apparatus in the present invention includes a processor to execute a program; and a memory to store the program which, when executed by the processor, performs processes of: transitioning a state of the user interface execution apparatus; issuing a prefetch request for data; storing the data; generating the code from an interface definition and a state transition definition; and selecting, before transitioning the state, data to be prefetched based on a difference between a data obtaining interface to be used in a state before the transitioning and a data obtaining interface to be used in a state after the transitioning.

  • Patent number: 10387019
    Abstract: This relates to a technology capable of efficiently deciding a screen layer to which a user input event should be delivered even when screen layers that do not receive the user input event are displayed in an overlapping manner other than a screen layer that should receive the user input event. A user interface device includes an acquisition unit, a transmission unit, a determination unit, and a decision unit. On the basis of inquiry information from the transmission unit, the determination unit concurrently determines, for a plurality of screen layers, whether input information is accepted in each of the screen layers. The decision unit decides the screen layer based on a determination result.

  • Patent number: 8987927
    Abstract: A charge and discharge control unit (41) sets an upper-limit charge and discharge electric power as an upper limit of electric power during charging and discharging of a electric storage device (11) based on temperature of the electric storage device (11) measured by a temperature measuring unit (21) and a state of charge of the electric storage device (11) specified by a charge state specifying unit (23). In the case where the operation state determined by an operation state determining unit (35) is a low-limit operation state, the charge and discharge control unit (41) sets the upper-limit charge and discharge electric power to be larger than that in the case where the operation state determined by the operation state determining unit (35) is a high-limit operation state.

  • Patent number: 4487362
    Abstract: A fixture for thermostatically mixing hot and cold water from hot- and cold-water pipes. The diameters of the annular axes of seals provided on both ends of a control valve are equal to the inside diameter of the valve guide for the control valve. The space left between the external surface of a temperature sensing element and the internal surface of the casing for the temperature sensing element is so narrow as to be adapted to allow the temperature sensing element to quickly respond to a change in the water temperature. A spring engages at opposite ends against a main valve and the control valve so as to bias the control valve against a valve seat.
