Abstract: An energy usage data visualization process includes receiving an energy data presentation request from a user, processing the energy data presentation request by the customer portal service module, and retrieving energy usage data associated with the energy data presentation request. The energy usage data is retrieved from a storage device, which is communicatively coupled to the customer portal service module. The service module produces a visual output based upon the presentation request and the retrieved energy usage data. The service module produces the visual output for presentation onto the display of the end user interface, by using an energy data visualization template of a template module application. The template module application is determined by the energy data presentation request, and is stored on the customer portal service module. The customer portal service module has a housing that is separate from the housing of the end user device.

Abstract: The invention provides a signal transmission device that transmits a signal applied to a pair of input terminals to a pair of output terminals insulated electrically from the pair of input terminals while reducing the influence of an external noise magnetic field. The signal transmission device has a pair of coils, a pair of magnetic sensors and a signal output section. Each of the coils is connected between the pair of input terminals. Each of the coils generates a magnetic field respectively in response to the input signal applied between the pair of input terminals. A direction of the magnetic field generated by one of the coils is opposite to a direction of the magnetic field generated by the other of the coils. Each of the magnetic sensors corresponds to one of the coils exclusively. Each of the magnetic sensors detects the magnetic field generated by the corresponding coil, and outputs a detection signal in response to the detected magnetic field. The signal output section outputs an output signal to the pair of output terminals. The output signal corresponds to a difference between the pair of detection signals outputted by the pair of magnetic sensors. In the difference, the signal component caused by an external noise magnetic field is canceled. On the other hand, in the difference, the signal component caused by the input signal applied between the pair of input terminals are doubled with respect to the input signal. Thereby, the signal output section outputs the output signal with high S/N ratio.
