Abstract: According to an embodiment, energy management system includes estimating module, preparing module and controller. Estimating module estimates energy demand of a home, and obtains estimated value of energy demand of home. Estimating module estimates energy generation amount and obtains estimated value of the generation amount. Preparing module prepares discharge strategy, based on the estimated energy demand and generation amount. Discharge strategy maximizes balance obtained by subtracting power purchase loss from power selling profit, by using a push-up effect.

Abstract: When the head temperature Tfinish, which is the head temperature at the time of completion of a preceding scan, is higher than the stable ejection temperature Tstable, the target temperature is made a temperature that is only a temperature value ?T lower than the head temperature Tfinish. On the other hand, when Tfinish, the head temperature at the time of print completion, is lower than the stable ejection temperature Tstable, the target temperature is made a temperature that is only a temperature value ?T higher than the head temperature Tfinish. Because of this it is possible to inhibit head temperature rise in the case where an image with a high print density is printed.

Abstract: An energy management system (EMS) according to an embodiment has an EMS functional system which estimates at least one parameter value indicating a property of a power conditioner device. The functional system estimates at least one parameter value indicating a property of the power conditioner device on the basis of measured values of the power conditioner device for converting a DC power to an AC power to output the AC power to a power distribution system, the DC power having been inputted from a power generator or the power storage device.

Abstract: An energy management system includes an overcharging-overdischarging risk storage and a generation storage optimization planner. The overcharging-overdischarging risk storage stores an overcharging-overdischarging risk indicating a risk for overcharging-overdischarging to a power storage device of a hybrid power conditioner for converting a DC power to an AC power to output the AC power to a power distribution system, the DC power inputted from a power generator or the power storage device, the hybrid power conditioner converting an AC power into a DC power to output the DC power to the power storage device, the AC power inputted from the power distribution system. The generation storage optimization planner calculates a control plan value for charging-discharging to the power storage device of the hybrid power conditioner on the basis of at least the overcharging-overdischarging risk, a power demand estimation, and a generated-power estimation for the power generator of the hybrid power conditioner.

Abstract: In a case where the temperature difference between first and second time points detected by a first temperature sensor provided in a print head is lower than a threshold temperature, a temperature correction for the first temperature sensor is performed based on a temperature detected by a second temperature sensor provided within a printing apparatus thereof. In a case where the temperature difference is higher than the threshold temperature, a temperature correction for the first temperature sensor is performed without using the temperature detected by the second temperature sensor.

Abstract: Provided is an inkjet printing apparatus that, when performing multi-pass printing using pigmented ink and image enhancing liquid for adjusting the glossiness, is capable of outputting a high-quality image in which gloss unevenness due to displacement of the printing position cannot be noticed. In order to accomplish this, dot arrangement data is generated based on input image data so that the dot arrangement of image enhancing liquid includes a greater low-frequency component in the spatial frequency than the dot arrangement of colored ink on a print medium. As a result, it is possible to suppress gloss unevenness even when printing position displacement occurs, while at the same time suitably suppressing a feeling of graininess in colored ink.
