Sun visors in motor vehicles have been around since the
1920s. Recently, Bosch decided that it was time to upgrade the design and
technology of sun visors that have remained virtually unchanged since their
inception. What they have come up with is known as the “Virtual Visor.” Bosch
states that the idea behind the Virtual Visor is to reduce sun glare, which can
impair the driver’s ability to see clearly while driving.
The technology is a transparent liquid crystal display (LCD) panel comprised of hexagonal pixels in a honeycomb grid. The transparent screen is used with an RGB camera inside the vehicle that tracks where the sun is coming from and where it shines on the driver’s face. Together, the LCD screen and RGB camera can track the driver’s face, track moving shadows, and track sunlight. Artificial intelligence takes these data and uses an algorithm to identify exactly where the driver’s eyes are. According to Bosch engineers, this algorithm was the most challenging piece of the technology. They wanted the algorithm to be able to do all of the tasks listed above – identify the driver’s face, track moving shadows, and locate which direction the sun was coming from – and then use that to constantly and accurately update the location and degree of shade of the Visual Visor. AI should ideally be able to provide relief from sun glare by casting shade directly over the driver’s eyes, Bosch says.
Bosch claims that one of the advantages to the Virtual Visor includes reduced sun glare and better visibility as drivers will be able to see through the visor even as it provides shade. In other words, Bosch believes that with the Virtual Visor, drivers would no longer block a portion of their view in order to get relief from the sun while driving.

Auto-GCAS stands for Automatic Ground Collision Avoidance
System and plays an important role in safety for fighter pilots when they enter
into combat. According to the Society of Automotive Engineers, a large number
of fatal accidents happen on the ground, or what is often referred to as
Controlled Flight into Terrain (CFIT). Due to the high-level of collisions both
mid-level air and on the ground, the Defense Safety Oversight Council (DSOC)
partnered with the Air Force Research Laboratory (AFRL) to design a way to keep
fighter pilots safer and less prone to CFIT. The result is the implementation
of Auto-GCAS on F-16 Fighting Falcons and the Lockheed Martin F-35 Lighting II
A number of different factors can cause CFIT including
unconsciousness and distraction and – until Auto-GCAS – pilots had no way to
combat or prevent CFIT. The F-16 and the F-35 aircrafts now have Auto-GCAS to fight
the dangers of CFIT and to reduce the number of related incidents. It does so
through intricate algorithms and what is referred to as a digital terrain
database; in other words, the technology can detect an impending crash, take
control of the aircraft, and completely avoid contact with the imminent terrain.
Specifically, SAE mentions that once the Auto-GCAS system determines that a
crash is inevitable, it takes control, rolls to wings level, and executes a 5g
pull until the aircraft clears the terrain.
Mark Wilkins and Finley Barfield received the prestigious Robert J. Collier Trophy from the National Aeronautic Association for their contribution to Auto-GCAS systems. SAE notes that since the F-16 was equipped with Auto-GCAS in 2014, seven airplanes and eight pilots have been saved. The hope is that further integration and innovation will take place, including further implementation of automatic air collision avoidance systems, implementation of ground/air collision avoidance systems and ways to implement Auto-GCAS into larger aircraft and unmanned aerial machines.
