(Glaser, 1972). Although choreoathetosis has been described (Peters, 1962;Logan and Freeman, 1969;Kooiker and Sumi, 1974;McLellan and Swash, 1974), only a few cases have been documented adequately. During the last two years we have seen involuntary movements in four patients, two of whom presented with severe choreoathetosis. These patients are described in the following case reports. (Accepted 5 September 1974.) 225 signs. A left carotid arteriogram showed a shift to the right of the anterior cerebral artery, and a pneumoencephalogram (AEG) showed displacement of the ventricles to the right without significant alteration of ventricular size or shape. A gross unilateral abnormality over the left hemisphere posteriorly was seen on EEG. The pathological significance of these findings was uncertain. His fits were bizarre in pattern and were asymmetrical, being more marked on the right, and being accompanied by transient aphasia. A three day course of corticotrophin (ACTH) was without effect, but when pheneturide 400 mg daily was started the fits appeared to decrease in frequency and severity. However, four days after starting this drug, he developed marked choreoathetoid movements involving head, neck, and upper limbs. Although it was felt at the time that this was due to the same process as that causing the fits, the movements disappeared when pheneturide was withdrawn.

The paper presents a performance analysis of Novel CMOS Integrated Pseudo PMOS UVPCO having zero static power dissipation. The main emphasis is on simulation of power and performance analysis along with the comparison with existing devices, which is used for Air Purification. This approach can improve calibration without the use of a high speed digital processor. The conventional devices consume high power and are not firm for long term monitoring. These devices are also suffered from low value of slew rate, high power consumption, and non linear characteristics but in this novel design the device has almost zero static power, less load capacitance on input signals, faster switching, fewer transistors, higher circuit density and the device has better slew rate. This device has a modest architecture, and suitable for Air purification and surface sanitisation.

This paper presents novel method to control output error of the Photo Catalytic Sensor (PCS) using fuzzy interface. Whig and Ahmad in 2014, proposed the spice model of PCS which is a type of ion sensitive FET and very useful to estimate the parameter BOD (Biological Oxygen Demand) which is generally used to estimate quality of water. PCS can also be used to calculate the amount of concentration level of oxygen required to purify the polluted air and sanitization of surface. The purpose to control the output error due to variation in temperature is due to the fact that the fluctuation of O 2 influence the threshold voltage, which is internal parameter of FET can manifest itself as a voltage signal at output but as a function of trans conductance gain. Hence, a system controlled by fuzzy logic which control the output error is proposed. This novel method is very useful because of their simplicity, robustness and successful practical applications. The proposed system is fast in operation which is further helpful for PCS which operates under sub-threshold conditions and reduced computation time. The system is user friendly and the outcomes of simulation are fairly in agreement with the theoretical estimation.
