Artificial Intelligence in your Sun Visor

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.

AI in your EV

Tim Sherstyuk embarked on an ambitious journey towards understanding and improving the efficiency of EV batteries. The idea initially came to him when he was a college student studying chemistry at Carleton University. He wanted to investigate why cell phone batteries die quicker than batteries operating other devices. He and his father, who is an electrical engineer, put their heads together to research why batteries die out and if there is a way to prolong the lifetime of batteries.

One hypothesis is that “pulse” charging can accomplish exactly this. The traditional method of charging – the constant-current method – inflicts a lot of damage and wear on batteries. The hope is that pulse charging will alleviate some of that wear on batteries while they charge.

The Use of AI

The Sherstyuk team incorporates the use of artificial intelligence in their studies of pulse recharging on batteries. They rely on AI because it offers much-needed insight that accelerates the feedback loop during experiments. In fact, other companies have taken advantage of AI, one of which is the Toyota Research Institute (TRI). They implemented AI into their tests and research on batteries and now assert that AI accelerates the progress of research and discovery. They currently use it to run 400 different battery tests and experiments at the same time which would be impossible through traditional channels. In their words, “AI accelerates R&D cycles.”

For the Sherstyuks, the goal is to improve the method of battery charging so that the battery itself lasts longer. Reducing impedance and the damage incurred from charging quickly are examples of what Sherstyuk aims to eliminate during the charging process. Fast charging raises the temperature of the battery which can lead to heightened cell degradation and potentially cause the battery to swell. The Sherstyuks conducted testing by using an adapter-like device that could potentially be built into the charging connector. AI provides real-time measurements during the charging process that helps Sherstyuk determine how much energy needs to go into the battery pack. After seven years of testing, the Sherstyuks see positive results. Though pulse charging is not new, the use of AI provides real-time feedback and data that was previously lacking. Sherstyuk’s hope is to fine tune pulse charging so that the lifetime of EV batteries is prolonged. This would have many benefits, according to Sherstyuk, including environmental benefits as longer battery life would lead to less battery waste.

Komatsu Developing Artificial Intelligence

Komatsu is developing a system of artificial intelligence to be used in large-scale construction sites. The artificial intelligence is being developed in an attempt to gather more data on the heavy equipment used in the construction sites and, more importantly, to increase the safety to equipment operators and ground personnel. Komatsu is one of the world’s leading manufacturers of heavy equipment, mining equipment, and other construction equipment. Komatsu is developing the artificial intelligence system along with NVidia, who is well-known as a computer hardware developer in industries such as commercial, retail, and medical. The construction artificial intelligence system, dubbed SmartConstruction, will have the capability to control heavy equipment and can identify and distinguish between ground personnel, inanimate objects, and heavy equipment around the entire construction site. Komatsu will be using NVidia’s Jetson computing platform as a basis for the artificial intelligence development. The Jetson platform is very small, about the size of a credit card, and powerful to compute virtual surroundings taken from the individual cameras used in all of Komatsu’s construction equipment. In addition to ground level cameras, drones will be used overhead the construction site to provide real-time updates as to local positioning of resources, equipment, and personnel. The drones will be operated by SkyCatch, another feature provided by NVidia as part of their Inception Program Startups. The first locations to use the new artificial intelligence technology will be in Japan, where an aging workforce and lack of qualified labor bring strong demand for computer-controlled equipment. In Japan, the technology will be fine-tuned and validated. However, the entire world will benefit from the new technology and after test runs are completed, the AI technology will be released worldwide. Komatsu is anticipating that SmartConstruction will decrease the dangers typically found in construction and mining work sites, all while increasing productivity and reducing costs to the end-users. -taken from www.sae.org
