摘要： A sync stripper circuit receives from a medical imaging modality a composite video signal with a horizontal sync frequency within one of first, second, third or fourth frequency ranges. The sync stripper circuit includes a circuit for stripping the composite sync signal from the received signal; horizontal sync detection circuit for detecting the horizontal sync signal from the stripped composite sync signal; a vertical sync detection circuit for detecting the vertical sync signal; an F1/F2 field detection circuit for detecting the F1/F2 field from the stripped composite sync signal; and a control circuit for controlling the horizontal sync detection circuit, the vertical sync detection circuit and the F1/F2 field detection circuit to operate in the selected one of said first, second, third or fourth frequency ranges of the received composite video signal. A serrating signal circuit inserts a horizontal signal into the vertical sync signal if serrating signals are absent therein.

摘要： The present invention relates to a tunable optical device 10 that includes an optical fiber device 12 having optical properties that vary with temperature and a heater 14. The heater 14 is thermally coupled to the optical fiber device 12. The heater 14 includes a metal layer 18 and two electrical contacts 20, 22 that are electrically connected to the metal layer 18. The electrical contacts 20, 22 are spaced apart from one another along the metal layer 18. The electrical resistance of the portion of the metal layer 18 between the contacts 20, 22 varies with temperature and serves as a resistive heater. The invention also includes a controller 16 that is electrically connected to the heater 14. The controller 16 provides electrical power to the heater 14 and measures the electrical voltage across the heater 14. The controller 16 compares the measured electrical voltage to a pre-selected reference value. The controller then regulates the amount of electrical current supplied to the heater 14. By regulating the amount of electrical current supplied to the heater 14 the temperature of the heater 14 is controlled.

摘要： A medical imaging system includes a video interface connecting different medical imaging modalities to a laser printer. The video interface includes a clock recovery phase-lock-loop (PLL) as a frequency synthesizer video signal from a modality. A second PLL inserts a pulse train equal to the horizontal frequency into an analog video signal having a vertical sync interval with no serrating pulses. This assures the clock recovery PLL will maintain lock during the vertical sync interval.
