Electrical Detection of Medical Malware

Hospital rooms beep and flash with many devices that are increasingly getting infected with malware (see “Computer Viruses Are ‘Rampant’ on Medical Devices in Hospitals”). But for several reasons, these gadgets are often incompatible with commercial security software.

Now, new technology developed by academic researchers could catch most malware on the devices just by noting subtle changes in their power consumption. This could give hospitals a quick way to spot equipment with dangerous vulnerabilities and take the machines offline. The technology could also apply to computer workstations used in industrial control settings such as power plants.

INTERVIEW AND SHORT ANSWER QUESTION ON IMAGE PROCESSING-BIOMEDICAL JOBS & NOTES QUESTION 21-40

21. Define subjective brightness and brightness adaptation?
Subjective brightness means intensity as preserved by the human visual system.
Brightness adaptation means the human visual system can operate only from
scotopic to glare limit. It cannot operate over the range simultaneously. It accomplishes
this large variation by changes in its overall intensity.

22. Define weber ratio
The ratio of increment of illumination to background of illumination is called as
weber ratio.(ie) ?i/i
If the ratio (?i/i) is small, then small percentage of change in intensity is needed
(ie) good brightness adaptation.
If the ratio (?i/i) is large , then large percentage of change in intensity is needed
(ie) poor brightness adaptation.
