    ® General Description. The Millennia 3155MVS/3155A Monitor is the Remote Control Unit in the Invivo Research, Incorporated 3150 Series MRI Monitoring System. This monitor provides Remote Control (through a cable or RF Radio Link) to a Omni-Trak 3150/Magnitude 3150M MRI Patient Monitor (located in the MRI Magnet Room). Used with the Omni-Trak ®...

    NOTE The 3150/3150M ETCO2 is turned Off when the Agent/ETCO2 is turned On at the ® Millennia 3155A. ® When the Millennia 3155A is used to monitor Agent/ETCO2, it must be located in the Magnet Room with the gas sample line connected directly to the front of the 3155A. If operating a dual monitor system, the 3155MVS and 3155A patient monitors are interactive with one another through the 3150/3150M.

    to continue in its active state. If the pulses are absent, U1A will quickly time out and the power supply will stop, as U14 and U11 will go into shutdown (having lost their enables). The test switch SW1, if in its leftward position (ON), will hold the cathode of diode D1 low, and maintain mono U1A in its active state indefinitely.

    The description of the 5V supply will also suffice for the 3.3V section, with exceptions as noted. The input power to U14 is RAWPWR, and it is applied all the time that the power supply has an input voltage. Turn-on of U14 is done via the /SHDN pin brought HIGH. When U14 becomes active, the gate drive to transistor Q26 turns it ON.

    Op amp U4B amplifies the difference of the voltage sensed across resistor R22 and the voltage from the resistors R39, R78, and R79, and controls transistor Q11. When the current rises excessively, transistor Q11 conducts enough to pull U11 pin 9 LOW through diode D29 to reduce the duty cycle of the drive into transistor Q6, effectively reducing the output current from the supply.

    LED. As long as the battery is good, the /EARLY_WARN line will be HIGH, and transistor Q2 will be ON. Hence, the LED shows YELLOW (RED plus GREEN). When the /EARLY_WARN line goes low (active), transistor Q2 will turn OFF; because transistor Q3 is still ON, the LED will show RED.
