    Abstract: An apparatus is disclosed which accurately measures, over a wide ambient temperature range, the average power derived from an electrical signal. Furthermore, embodiments of the present invention can be fabricated with inexpensive, off-the-shelf components and can have excellent circuit characteristics at RF frequencies. These results are obtained in an illustrative embodiment of the present invention that comprises a first thermal detector, a second thermal detector, an error amplifier and a summer. The first thermal detector provides a reference signal, which varies with the ambient temperature, to the error amplifier. The summer receives the signal to be measured and the signal output from the error amplifier, and outputs to the second thermal detector a composite signal, which is indicative of the sum of the power derived from input signal and the output signal from the error amplifier. The second thermal detector receives the composite signal and outputs a feedback signal, which is indicative of power derived from the composite signal, to the error amplifier. The output signal, which is indicative of the power derived from the input signal, is the output of the error amplifier. The error amplifier advantageously subtracts the feedback signal from the reference signal, and advantageously outputs the amplified difference to the summer.

    Abstract: A solar energy flux integrator includes a semiconducting solar cell positioned to receive solar radiation, and a micro-coulombmeter connected to receive current from the solar cell. The micro-coulombmeter comprises a glass capillary filled with a mercury salt electrolyte having an indicating bubble and two mercury electrodes. A series resistor is provided which has a resistance value to slow the movement of the bubble when low levels of solar energy are incident on the cell so that movement of the bubble is directly proportional to the incident solar flux. This series resistor compensates for the spectral shift towards blue of the indirectly received solar radiation, which spectral shift otherwise causes the measured integrated value of solar flux to be too high due to the greater sensitivity of the solar cell to light of shorter wavelengths. A parallel resistor is provided to scale the output of the solar cell to the Micro-Coulombmeter and a reversing switch is connected to permit travel of the indicating bubble in opposite directions.
