If you have never witnessed the aftermath of a hurricane firsthand, it is hard to imagine the amount of destruction and abject misery left in its wake. With four major hurricanes to date, this year’s highly active hurricane season has brought record destruction to the Unites States, Mexico, and the Caribbean.
As of this writing, cleanup from the most recent storms is still in its early stages. Many have been left homeless while others do not have electricity, water, and other basic necessities. On behalf of Infraspection Institute, I wish to thank fire, rescue, police, and military personnel for all that you have done and will continue to do in the future. To those who are still struggling, you are in our thoughts and prayers.

Measuring motor temperature is often a challenge since electric motors differ widely in their design and construction. While many have suggested measuring the motor casing along the stator, this method does not work well for motors that are fan cooled or exposed to external air currents. For uncooled motors, this approach can produce varying temperature values depending upon the location of the subject temperature readings.
A specification commonly provided for thermal imagers is Instantaneous Field of View or IFOV. Many people mistakenly believe that IFOV values provide meaningful information about a thermal imager’s performance. Unfortunately, this is simply not true.
Originally developed for evaluating the optical performance of thermal imaging systems, IFOV values were intended to allow a user to calculate the minimum target size needed to achieve 50% probability of detection at any given distance. Using IFOV values to evaluate modern thermal imagers and radiometers is unreliable for several reasons:
