Abstract: A method for controlling an information terminal, including: (a) causing a display of the information terminal to display a first screen that includes a message recommending an action that leads to a reduction in a power consumption amount of a facility; and (b) causing the display to display a second screen that prompts an operator to execute an input operation for adjusting the frequency at which (a) is executed, in which, when the input operation is executed, (a) is executed at the frequency adjusted according to the input operation.

Abstract: An information terminal control method includes: (a) predicting whether an amount of power consumption in a shop exceeds a target value; (b) when the amount of power consumption in the shop is predicted to exceed the target value, causing a display of an information terminal to display a screen displaying a time period during which the amount of power consumption in the shop is predicted to exceed the target value; and (c) causing the display to display a screen displaying a message that presents an action to reduce the amount of power consumption in the time period.

Abstract: A storage battery control apparatus includes: a storage battery state detection unit which obtains a remaining SOC which is an SOC of a storage battery at the start of a supply and demand control period; an offset power value determination unit which determines an offset power value that is a power value indicating charge or discharge; an adjustment instruction value obtainment unit which obtains an adjustment instruction value indicating a state of charge and discharge of the storage battery; and a charge and discharge control unit which performs control of discharging power from the storage battery to the grid or charging power from the grid to the storage battery, the power having a magnitude of a first power value which is a power value obtained by adding the offset power value to the adjustment instruction power value indicated by the adjustment instruction value.

Abstract: When a focus error signal (FE signal) is detected with an astigmatic method, a track crossing component leaks into the FE signal. Another detection method for the FE signal would reduce the leaking signal, but is not applicable when the light use efficiency decreases. An optical crosstalk correction amount determination unit (1000) determines a correction amount to correct an output of a tracking error detection unit (120) based on optical crosstalk from a TE signal to an FE signal occurring in reflection light from an optical disc (102) when a spot crosses a track. An output of the tracking error detection unit (120) is multiplied by the determined correction amount, and added to an output of the focus error detection unit (118). A focus control unit (138) executes focus control based on the addition result. This effectively reduces a TE signal component that leaks into the FE signal due to optical crosstalk.

Abstract: A server device without a means for accessing an IC memory included in a data storage medium can check whether or not a data storage medium includes an IC memory. A portable optical disc medium (100) includes an IC memory (106) accessible through proximity wireless communication and a computer-readable recording part (101). The recording part (101) includes a user-data area (104) in which content data is recorded and a disc management information area (103) in which information for management of recording and reproducing the content data. In the disc management information area (103), medium identification information identifying the optical disc medium (100) and presence indication information indicating that the optical disc medium (100) includes presence of the IC memory (106) in a manner such that the presence indication information does not allow changing.
