Thermaltake cooling fan. Thermaltake Technology Co., Ltd. (Chinese: 曜越科技; pinyin: Yàoyuè Kējì; To Exceed Radiant Technology) is a Taiwanese manufacturer of PC case designs, power supplies, cooling devices and other peripherals. Its main headquarters are located in Taipei, Taiwan. [2]
Essentially, the meter's shunt resistor, used to generate a voltage proportional to load current, is replaced by one of value typically 100 times larger, with protective diodes. Readings of the modified meter have to be multiplied by the resistance factor (e.g. 100), and maximum measurable power is reduced by the same factor.

In contrast, a linear power supply regulates the output voltage by continually dissipating power in the pass transistor. The switched-mode power supply's higher electrical efficiency is an important advantage. Switched-mode power supplies can also be substantially smaller and lighter than a linear supply because the transformer can be much smaller.
An electricity meter, electric meter, electrical meter, energy meter, or kilowatt-hour meter is a device that measures the amount of electric energy consumed by a residence, a business, or an electrically powered device over a time interval. Electric utilities use electric meters installed at customers' premises for billing and monitoring purposes.
Crank arm based power meter. The small box on the rear of the left crank arm contains the strain gauges. A cycling power meter is a device on a bicycle that measures the power output of the rider. Most cycling power meters use strain gauges to measure torque applied, and when combined with angular velocity, calculate power. [1]
A dive computer, personal decompression computer or decompression meter is a device used by an underwater diver to measure the elapsed time and depth during a dive and use this data to calculate and display an ascent profile which, according to the programmed decompression algorithm, will give a low risk of decompression sickness.
