Design: pulmonary hypertension alarm an anesthesia monitoring system is measuring the pressure output from a swan-ganz pulmonary artery catheter to evaluate pulmonary hypertension intraoperatively. since the anesthesiologist is also monitoring several other physiologic systems concurrently (e. g., ecg, eeg, respiratory rate, blood pressure, the pressure monitor sounds an alarm when the pressure goes too high or too low. the pressure output of the catheter, ranging from 0 - 100 mm hg, is linearly mapped to voltage through its transduction mechanism to be 0 - 10 v. design a circuit using a comparator that will sound the alarm when the pressure rises above 25 mmhg. assume that the pressure catheter signal has a noise component of ± 0.1 mmhg; your comparator should have a hysteresis range that is twice this noise limit. let your input signal to the circuit from the pressure catheter be represented as vin. use dc power sources as needed in your circuit design, and specify the rail voltage(s) for the op-amp(s). the alarm can be considered a "black box" load that can be activated with a voltage greater than 5 v (vo > 5 v).

Tom is having a problem with his washing machine. he notices that the machine vibrates violently at a frequency of 1500 rpm due to an unknown rotating unbalance. the machine is mounted on 4 springs each having a stiffness of 10 kn/m. tom wishes to add an undamped vibration absorber attached by a spring under the machine the machine working frequency ranges between 800 rpm to 2000 rpm and its total mass while loaded is assumed to be 80 kg a) what should be the mass of the absorber added to the machine so that the natural frequency falls outside the working range? b) after a first trial of an absorber using a mass of 35 kg, the amplitude of the oscillation was found to be 10 cm. what is the value of the rotating unbalance? c) using me-3.5 kg.m, find the optimal absorber (by minimizing its mass). what would be the amplitude of the oscillation of the absorber?
