    摘要: A method and apparatus for internally wrapping the surface of a conduit, cylinder or pipeline with a sealing membrane which is adhered to the interior surface. The apparatus applies the membrane in a helical spiral by taking the membrane from a roll and pressing it against the interior surface while applying an adhesive and while transporting the roll longitudinally in the conduit on a transport assembly that rolls internally in the conduit.

    摘要: In accordance with an embodiment, a noise reduction circuit includes one or more phase sampling circuits that receive an electromagnetic signal and splits the signal into an illuminated component and an ambient component. The illuminated component is transmitted along an illuminated signal path and converted to a digital signal and the ambient component is transmitted along an ambient signal path and converted to a digital signal. The digitized ambient component is subtracted from the digitized illuminated component to generate a light signal with a reduced noise component.

    摘要: A method for protecting against over voltage in a power supply comprises monitoring current amplitude and direction on an output connection of a power source that combines power from a plurality of power sources, and determining occurrence of a fault condition of the monitored power source based on the current amplitude and direction. In a fault condition of the monitored power source, operation of the monitored power source subject to the fault condition is terminated while continuing operation of the plurality of power sources exclusive of the monitored power source.

    摘要: A power system has a first power supply operatively connect in parallel to a second power supply. The output of the first power supply is connected to the input of a switching device, such as a mosfet. The output of the switching device is the output of the power system. A measuring device, such as a differential amplifier measures the polarity between the input and output of the switching device. A controller connected to the switching device permits the switching device to conduct current if a first polarity is present between the input and the output. The controller interrupts current flow if a second polarity is present between the input and the output.

    摘要: A DC-DC voltage converter comprises a controller, two switches, a transformer and two rectifying diodes. The transformer has a first winding, a second winding and a center tap. Input voltage in connected between the center tap and ground. An anode of each diode is connected to the outer ends of the two windings and the cathodes of the two diodes are connected together to provide a positive output with respect to ground. Each switch is connected between an outer end of one windings and ground. The controller generates control signals to turn the switches on and off for limited periods of time in phase opposition to alternately connect the outer ends of the first and second winding to ground to cause current to flow alternatively in one of the windings and induce a voltage in the other winding that is additive to the input voltage, thereby providing an output voltage greater than the input voltage. The converter provides stable operation with good voltage regulation over a wide range of load conditions without the use of feedback.
