  • Patent number: 9099863
    Abstract: A surgical generator and related method for mitigating overcurrent conditions are provided. The surgical generator includes a power supply, a radio frequency output stage, an overcurrent detection circuit in operative communication with an interrupt circuit, and a processor. The power supply generates a power signal and supplies the power signal to the radio frequency output stage. The radio frequency output stage generates a radio frequency signal from the power signal. The overcurrent detection circuit detects an overcurrent of the power signal and/or an overcurrent of the radio frequency signal. The interrupt circuit provides an interrupt signal in response to a detected overcurrent. The processor receives the interrupt signal and supplies a pulse-width modulation signal to the power supply and incrementally decreases the duty cycle of the pulse-width modulation signal in response to the interrupt signal. The radio frequency output stage may be disabled in response to the detected overcurrent.

  • Patent number: 8624666
    Abstract: 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.

  • Patent number: 8335065
    Abstract: 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.

  • Patent number: 8150019
    Abstract: A path redundant, hardware efficient communications interconnect (1) has embodiments that can present true any-to-any interconnect capability for first and second pathways (2) and (3) and can utilize double throw switches (25) with or without single throw switches (24) perhaps in staged collectives of sub arrays (4), (5), (6), (9), and (10). A loop-back communications interconnect (22) can be accomplished by an interleaved sub array (26). A quadrilateral center stage sub array (21) can be combined with asymmetric side stage sub arrays for hardware savings that are tenths of a percent of a traditional interconnect and even present eight fold savings over prior reduced hardware interconnects.
