Abstract: A power consumption meter is disclosed for measuring the power consumed by a load on a power conductor, wherein the electronics of the power consumption meter are isolated from lightning and power transients. The meter has a first GMR sensor that is disposed proximate the power conductor and is magnetically coupled to the power conductor. The first GMR sensor detects magnetic flux in the power conductor and produces a first output responsive to the detected magnetic flux that is representative of the current flowing through the power conductor. A second GMR sensor is disposed proximate the power conductor and is magnetically coupled to the power conductor. The second GMR sensor detects magnetic flux in the power conductor and produces a second output responsive to the detected magnetic flux that is representative of the voltage on the power conductor.

Abstract: An optoelectronic active circuit element is created by the combination of a light source, an optical control filter and a photocell intimately coupled together. The light source has at least one light emitting surface emitting light energy of a specified frequency bandwidth and the photocell has at least one light absorbing surface for receiving the emitted light energy. The optical control filter includes a photorefractive material responsive to an input signal. The optical control filter may also include a polarization filter. The optoelectronic active circuit element modulates the amplitude, frequency or both of the emitted light energy in response to the input signal to produce a characteristic function of the output of the device that is similar to that of a traditional active circuit element, as well as many variations on that function.

Abstract: A long-life, electrical energy source having an adjustable output is comprised of a light emitting phosphor activated by a radioisotope and coupled to a plurality of photovoltalic cells that have their outputs electrically connected together. The output power of the electrical energy source is effectively regulated by selectively changing the connections of the outputs of the photovoltaic cells in response to the progression of time.

Abstract: An electrical energy source is created by the combination of a light emitting polymer material having at least one light emitting surface emitting light energy of a specified frequency bandwidth and a photovoltaic cell having a light collecting surface and a pair of electrical contacts. The light collecting surface of the photovoltaic cell is optically coupled with the light emitting surface of the light emitting polymer material. An open-circuit voltage is generated between the pair of electrical contacts as a result of the absorption of emitted light energy from the light emitting polymer material by the photovoltaic cell. The light emitting polymer comprises a mixture of a polymer labelled with a tritium and an organic compound which emits light energy when subjected to radiation generated by the tritium. The organic compound is at least partly bonded to the polymer and the mixture is translucent at the specified frequency bandwidth of the light energy.
