Abstract: An electrical power control apparatus and method for power factor correction in a conventional 60 hertz or other conventional frequency electrical AC power supply communicated to an inductive load. A plurality of interruptions of current in the line on both sides of an AC current oscillation, are created to control the power factor in a circuit energizing an inductive load. Additional power factor control and correction is provided by grounding of the line during each interruption. A controller controls the length and duration of each interruption based on preprogramming or input regarding current phase read or calculated in the line.

Abstract: An electrical power control apparatus and method for a conventional 60 hertz or other conventional frequency electrical AC power supply voltage waveform to proved an effective output current and voltage to an intended load whereby the output frequency is the same as the input frequency. Using a switching means capable of micro switching the current on and off, and a plurality of substantially equal length and duration interruptions of current on both sides of an AC current oscillation, the output effective voltage and resulting current may be preset and controlled to a pre-programmed output level regardless of input voltage having one or more phases. Or, the output voltage and resulting current may be continually monitored with the load integrated into the circuit being monitored and continually adjusted to yield maximum power use savings while avoiding damage to the components attached to the circuit.

Abstract: A Doppler control circuit for a CW or pulse Doppler radar system for monitoring not only the phase shift between echo signals from several targets but also the amplitude difference between the several targets and to further tune the radar to a particular target among one or more targets from which echo signals return. The control circuit can be used in state of the art CW or pulse Doppler type radar systems. In a further system, a special circuit is provided for conditioning selected portions of the Doppler frequency spectrum to attenuate or de-emphasize portions of the echo signal corresponding to selected targets in the radar system environment, such as rain or stationary wayside objects, in order to give such echo signals less weight in determining roadway hazards.

The control circuit can be used in state of the art CW or pulse Doppler type radar systems. In a further system, a continuously generated radar signal is repeatedly transmitted at different frequencies in time division fashion to define a succession of transmit and receive frames. The receive frames are divided into a plurality of time interval windows with selected windows being used to detect received signals at the different frequencies. The remaining windows can be used for subsystems of the radar system.
