    • According to one aspect, a method of providing utility usage information to a user includes automatically receiving at a host system utility usage data collected by a plurality of utility meters at a user site, processing the received utility usage data, storing the processed utility usage data in a database, and reporting utility usage information based on the utility data, via a reporting interface, based on one or more interactive selections received from a user. The plurality of utility meters includes a plurality of different types of utility meters. The host system is at a location remote from the user site. A first portion of the utility usage data is received via a first communications network and a second portion of the utility usage data is received via a second communications network. The first communications network is different from the second communications network.

    • [Problem] To calculate power consumption with high accuracy at a jack portion in a power strip and in a power measurement method.
      [Solving Means] The problem is solved by a power strip including: a second power line 12 between which and a first power line 11 a power supply voltage is applied; a jack portion 1a; a current meter 30 configured to measure a current being supplied to an external electrical device from the jack portion 1a; a first photocoupler 41 including a first light emitting diode 41a connected between the first power line 11 and the second power line 12 and configured to output a first output signal S 1 whose level is changed when the power supply voltage exceeds a first threshold V 1 ; and a computing unit 33 configured to calculate a power value by using instantaneous values I(t) of the current measured by the current meter 30 and instantaneous values V(t) of the power supply voltage estimated from the length X 0 of a period when the level of the first output signal S 1 is changed.
    • [问题]为了在电源板的插座部分以功率测量方法高精度地计算功耗。 [解决方案]通过电源板解决问题,包括:第二电源线12和第一电源线11之间施加电源电压; 插座部分1a; 电流计30,被配置为测量从插座部分1a提供给外部电气设备的电流; 第一光耦合器41,包括连接在第一电力线11和第二电力线12之间的第一发光二极管41a,并且被配置为输出当电源电压超过第一阈值V 1时电平变化的第一输出信号S1; 以及计算单元33,被配置为通过使用由电流表30测量的电流的瞬时值I(t)和从该时段的长度X 0估计的电源电压的瞬时值V(t)来计算功率值, 第一输出信号S1的电平改变。
