Abstract: Electronic assemblies for medical devices are described, including an electronic assembly that includes a body, at least one imaging device, and at least one light source. The body may include a plurality of electrical connection points and a plurality of electrical traces in a material that is electrically insulative. The plurality of electrical connection points may be on one or more external surfaces of the body. The plurality of electrical connection points may include proximal and distal connection points. Each electrical trace may connect a proximal connection point to a respective distal connection point. The at least one imaging device may be coupled to one or more of the distal connection points and/or the at least one light source may be coupled to one or more of the distal connection points.

Abstract: A fuel sensor assembly includes a housing and back plate forming a cathode, and a chamber containing an anode. Fuel flows into the chamber surrounds the anode and is continuously replenished providing accurate and current measurements of fuel characteristics indicative of fuel content. A first opening and a second opening are offset a distance creating a flow path through the chamber that constantly circulates and replenishes fuel adjacent the sensor. The offset first and second openings create improved fuel content measurements by improving circulation of fuel through the chamber and around the anode.
