Embodiments of the present disclosure generally relate to devices and methods for sterilizing equipment. More particularly, one or more embodiments described in the present disclosure are directed to portable devices for sterilizing medical equipment in emergency situations. The sterilization devices and method of the present disclosure address an unmet need for sterilizing surgical equipment in a manner that is not only effective and time-efficient, but is also portable and reliable enough to use in emergency medical situations in remote locations where modern sterilization equipment is not available.

Sterilization device and methods

A device for signal processing. The device includes a signal generator, a signal detector, and a processor. The signal generator generates an original waveform. The signal detector detects an affected waveform. The processor is coupled to the signal detector. The processor receives the affected waveform from the signal detector. The processor also compares at least one portion of the affected waveform with the original waveform. The processor also determines a difference between the affected waveform and the original waveform. The processor also determines a value corresponding to a unique portion of the determined difference between the original and affected waveforms. The processor also outputs the determined value.
