Driverless cars have been a dream of mankind for many years. At the 1939 New York World Expo, the “Futurama†first mentioned the automated highway and regarded it as an important component of the “future worldâ€. Today, emerging electronic technologies have turned past illusions into reality, making Google's driverless cars a household name. ConTI, Bosch and Denso have publicly predicted that the world's first fully automated driverless car will be available in 2020. In addition, major automakers and semiconductor manufacturers around the world are constantly innovating to develop driver assistance systems for consumers.
The Advanced Driver Assistance System (ADAS) consists of a series of electronic technologies designed to ensure the safety of the vehicle. ADAS is able to maintain a safe distance from other vehicles, alert drivers to dangerous situations, and protect passengers and pedestrians from bad driving habits, helping to prevent accidents. Automated driverless vehicles not only allow the driver to use time more efficiently during commuting or long-distance travel, but also help reduce vehicle crashes and prevent casualties. It can be seen that safety has always been one of the primary driving forces for the development of this technology. According to the Huffington Post, the driver's distraction has become a major focus of the policy agenda. Except for the nine states, the other states have passed bills to deal with this issue.
Camera-based ADAS technology will play an important role in this field. It has been around for a while and has matured in recent years. In the past, this technology was only used in high-end models, and over time it was gradually adopted in mid-range and economy cars. By installing front, rear or surround cameras and visual processing ECUs, ADAS technology provides drivers with a variety of pre-existing functions such as LDW (lane departure warning), parking assist, front/surround view, anti-collision Features and more. The US government has recently developed a federal standard requiring that all new vehicles with vehicles weighing less than 10,000 pounds must be equipped with spare cameras by mid-2018. According to Strategy AnalyTIcs, as of 2020, more than 100 million vehicles worldwide will be equipped with camera modules.
What are the basic requirements for the camera module in the vehicle environment?
The camera must be able to operate in the temperature range of minus 40 to 85 degrees Celsius and have a long service life without any quality problems. Current trends require support for higher temperatures (eg, 125 degrees Celsius) because they are applied to a fanless enclosed environment and mounted on top of the windshield.
The camera must remain in focus regardless of temperature changes; the temperature of the camera itself does not affect the focus of the picture.
The camera's system solution must be streamlined.
Due to its resolution and functional complexity, the ADAS camera requires an external flash memory to store system code. To fully realize the capabilities of this technology, automotive camera module manufacturers are looking for high quality, reliable and durable components. As the world's leading semiconductor supplier and leader in automotive flash memory products, Spansion is able to offer automotive manufacturers serial interface flash memory products for automotive applications, namely FL-S and FL-1K, which meet the requirements of automotive applications ADAS technology.

In addition, Spansion has more than 20 years of experience in automotive electronics and has an exciting blueprint for future growth to ensure that the flash memory needs of all vision-assisted driving applications will be met in the future.
A mining light tower is a tall structure equipped with powerful floodlights that are used to illuminate large areas in mining operations. These towers are typically portable and can be easily moved around the mining site as needed.
The main purpose of a mining light tower is to provide sufficient lighting for workers to safely carry out their tasks during nighttime or in areas with low visibility. This is particularly important in underground mines where natural light is limited or absent.
Mining light towers are usually powered by diesel generators or other portable power sources. They are designed to withstand harsh mining environments, including extreme temperatures, dust, and vibrations.
The height of the light tower allows for a wide coverage area, ensuring that the entire mining site is well-lit. The floodlights used in these towers are high-intensity discharge (HID) lamps or light-emitting diodes (LEDs) that can produce a bright and focused light beam.
In addition to providing illumination, some mining light towers may also have features such as telescopic masts, adjustable light angles, and remote control operation for enhanced convenience and flexibility.
Overall, mining light towers play a crucial role in ensuring the safety and productivity of mining operations by providing adequate lighting in challenging work environments.
