2 Pyxis Features: Day or night real-time sensing Platform agnostic (fixed site, mast, buoy, drone, handheld etc.) Gimbal mount for automated scanning Easy installation and integration Simple user interface for real-time local or remote operation and monitoring Pyxis Vision Science software for highlighting regions of interest MOUNTING OPTIONS drone handheld oil rig

3 The Power of 400% BETTER DETECTION THAN THERMAL crude oil 1 crude oil 2 diesel etherm Pyxis measures both the thermal and polarization content of an oil spill scene. etherm combines the two for superior detection across all conditions tested, including the detection of recoverable oil in both flat water and breaking waves. DETECTION OF OIL ON WATER - DAY OR NIGHT day Thick Oil Thin Oil night A time lapse, overnight test shows the detection performance of polarization imagery from 3 to more than 50 times better contrast over thermal imaging. The polarimetric contrast is consistent throughout the night whereas the thermal contrast essentially went away several times throughout the night.

4 Real-Time Imaging for... Detection and tracking of oil and diesel on water and shorelines Differentiating between thick and thin oil Remote monitoring of rigs and wells Reducing manpower and costs associated with monitoring Search and rescue for watercraft and downed aircraft OIL SHEEN IN COMPLEX ENVIRONMENTS surface wellings kelp forest oil sheen sun glint etherm Following the Santa Barbara oil spill in 2015, oil is evident and detectable in an aerial survey using Pyxis, even after clean-up efforts. While thermal imagery requires some small thermal difference between the object (oil) and the background (water), polarization imagery has no such limitation. The Pyxis captures thermal and polarized imagery and fuses both data types into our proprietary etherm data product. Our software experts have developed Pyxis Vision Science to filter through the data and identify the things that matter most, highlighting them with etherm. Oil on water can be distinguished from land, sea kelp, and sun glint, or colorized for greater clarity.

6 Local and Remote Operation Day and night operation Fresh and emulsified oil Works in calm and rough conditions Low light capabilities Automated detection EMULSIFIED OIL WITH WAVES etherm It s common for oil to become emulsified over the course of a spill. Being able to identify emulsified oil is a crucial part of spill response efforts. Pyxis provides this much needed capability.

7 Beach Assessment Oil on Sand and Rocks Pyxis LWIR Camera DETECTION OF OIL ON SAND AND ROCKS oiled rock oil on water oiled sand clean water etherm Recent testing shows Pyxis as an asset for detecting oil on sand and rocks. A small beach scene was created and a small amount of oil was placed on one rock and onto the sand. While not visible with thermal, the oil is clearly visible in the etherm images taken with Pyxis. Once the oil soaks into the sand, it s undetectable in thermal and polarization. However, when water washes over the rocks and sand mimicking waves crashing on the beach, the oil is washed back up to the surface and detected by using the Pyxis with etherm. PATENTS PENDING
