  • Patent number: 9709594
    Abstract: A laser Doppler velocimeter uses self-mixing amplification of backreflections from scatterers below the surface of a flow. A time domain signal is divided into segments that are roughly equal to a transit time of particles through a focus of a laser beam. The segments are connected to a frequency domain through the use of an FFT algorithm to produce frequency domain data segments. Signal-to-noise ratio is enhanced through signal processing techniques using the segments to produce a final enhanced signal spectrum.

  • Patent number: 9041587
    Abstract: According to one aspect of the present invention, a radar system is provided which accurately measures the surface profile in a wide sector beneath and forward of a helicopter, to aid low level transit and landing in poor visibility. This uses an electronic beam synthesis technique to form multiple beams directed at the area of interest, each measuring the distance to the first reflected signal received by each beam. These distances represent the profile of the ground and any objects on the ground. A processor then compares the measured profile with the ideal ground profile for safe landing. If the deviations from straight and level exceed the specified requirement for safe landing, or if sufficient rotor clearance is not detected, then a warning is given to the operator. A display will show the measured ground profile highlighting the unsafe regions, allowing the operator to seek a safe region to land.

  • Publication number: 20140098584
    Abstract: A passive power factor correction (PFC) circuit is disclosed. It converts an AC input voltage into at least one DC output voltage. A diode bridge and a diode pair rectify the AC input voltage and provide first and second rectified voltages, respectively. A resistor applies the second rectified voltage to a first capacitor that stores the first voltage. A diode applies the first voltage to an inductor. The inductor applies the first rectified voltage to an output capacitor that stores the DC output voltage. The passive PFC circuit is intended to expand commonly used full-wave bridge rectifier and following storage capacitor. It can replace an input circuit, including low pass filter, in many applications even if improved power factor is not required. The passive PFC specifically targets size of the inductor while avoiding any switching, and maintaining power factor that challenges active PFC circuits. Early prototypes reached power factor of 0.99 while driving a 100 W load.
