Computerized tomography, using the EMI Scanner, allows the diagnosis of cerebral atrophy or hydrocephalus to be made with the same degree of accuracy as conventional neuroradiological methods. Ventricular measurements made on EMI scans have been compared with those from pneumoencephalograms and ventriculograms. A range of normal ventricular measurements for the EMI scan is suggested.

Switching power converters are widely used due to their excellent efficiency, but they inherently generate ripple. Passive low-pass LC filters have been traditionally employed to meet ripple and EMI specifications [1]. These passive filters can contribute considerably to the volume and weight of a power converter. In particular, capacitors can become relatively large in order to meet strict rip...

this paper presents novel active filter for mitigation electromagnetic interference (emi) and other adverse effects of pulse width modulation (pwm) inverter-fed ac motor system. an active filter proposed and devised for this system is characterized by sophisticated connection of two small separate filters, capable of mitigating all the adverse effects. this paper provides high frequency models ...

Real-time assessment, known as ecological momentary assessment (EMA), and real-time intervention (ecological momentary intervention [EMI]) can significantly extend the reach and impact of interventions to help individuals reduce their drinking behavior. For EMA, the user provides information on the variable of interest (e.g., drinking or craving) via a mobile device.This data reporting can occu...

In this report, the possibilities of reducing EMI in GALS systems are investigated and presented. Based on the special software tool for EMI analysis, several different abstract models of GALS circuits have been designed in order to extract a realistic pausable clock behavior. Based on the clock behavior, we have been able to analyze using our tool the current profile of each modeled system, bo...

This paper describes the relationship among damped oscillation, frequency-impedance characteristics (f-z characteristics) and conducted EMI occurring in induction cooking. The R-L-C equivalent circuit of induction pot is proposed. The relationship among ring, f-z characteristic and conducted EMI are verified by experiment. Finally, the reduction technique for damped oscillation is proposed usin...

Electromagnetic interference (EMI) includes any electromagnetic field signal that can be detected by device circuitry, with potentially serious consequences: incorrect sensing, pacing, device mode switching, and defibrillation. This is a unique case of extracardiac EMI by alternating current leakage from a submerged motor used to recycle chlorinated water, resulting in false rhythm detection an...

INTRODUCTION The aim of the study was to assess and classify incidents of electromagnetic interference (EMI) by second-generation and third-generation mobile phones on critical care medical equipment. METHODS EMI was assessed with two General Packet Radio Service (GPRS) signals (900 MHz, 2 W, two different time-slot occupations) and one Universal Mobile Telecommunications System (UMTS) signal...
