TL;DR: In this article, a peak power ratio generator is proposed for measuring the peak power level of extremely narrow pulses in the gigahertz radio frequency bands in the GHz band. But the generator is not suitable for high-frequency bands.
Abstract: A peak power ratio generator is described for measuring, in combination with a conventional power meter, the peak power level of extremely narrow pulses in the gigahertz radio frequency bands. The present invention in a preferred embodiment utilizes a tunnel diode and a back diode combination in a detector circuit as the only high speed elements. The high speed tunnel diode provides a bistable signal and serves as a memory device of the input pulses for the remaining, slower components. A hybrid digital and analog loop maintains the peak power level of a reference channel at a known amount. Thus, by measuring the average power levels of the reference signal and the source signal, the peak power level of the source signal can be determined.

TL;DR: In this article, a system to monitor energy use is described, where a gateway receives the energy consumption data from an electricity meter and an energy consumption graph is calculated by using the consumption data.
Abstract: A system to monitor energy use is disclosed. According to one embodiment, a computer-implemented method comprises receiving energy consumption data from a gateway, wherein the gateway receives the energy consumption data from an electricity meter. The energy consumption data is stored, and an energy consumption graph is calculated by using the energy consumption data. The energy consumption graph is transmitted to an end device, and the energy consumption graph is displayed on the end device.

TL;DR: The main finding is that software and usage typology could affect power consumption more than hardware.
Abstract: We analyze the power consumption of several IT devices placed in a research center affiliated to our University. The data collection lasted about one year and the analysis let us identify: i) the average instant power consumption of each type of device ii) trends of the instant power consumption curves iii) usage profiles and their power consumption iv) energy savings obtained from a different use of resources. Our main finding is that software and usage typology could affect power consumption more than hardware. Keywords—Green Computing, IT Energy Management, Electricity Meter, Data Analysis
