How Do Vehicle Collision Avoidance Systems Work?

by Jaymie Murray 11. January 2016 14:32

Imagine that you’re slowly making your way down a dark highway as your wipers struggle to keep up with the downpour that is assaulting your windshield. As you squint to make out the yellow lines painted on the road, a car traveling next to you suddenly changes into your lane and cuts you off. Before you have time to react and hit the brakes, your car automatically slows down, avoiding a serious accident.

This is a common scenario with newer cars fitted with pre-collision avoidance systems. These active safety systems use Doppler radar to detect objects that come into a vehicle’s path, triggering the brakes before impact. Typically, a radar detector is placed towards the front of a vehicle, such as within the grill. This detector sends out high frequency waves and then interprets the signals that bounce back, which would indicate object location, speed, and the direction it is traveling.

In order for the system to process all of this information and take action in a matter of milliseconds, a delay needs to be introduced. Linear Surface Acoustic Wave (SAW) delay lines are typically used in collision avoidance systems because they are smaller and less expensive than other delay line options. SAW delay lines used in collision avoidance systems operate across public frequency bands, and system designers would typically down mix the radar frequencies in order to process them through one channel with a constant delay.

This gives the system all of the information it needs to determine if a collision is imminent, and allows it to respond by automatically deploying the brakes, tensing seatbelts, or taking other safety precautions rapidly enough to avoid impact.

API Technologies' Most Popular Blog Posts of 2015

by Jaymie Murray 23. December 2015 10:55

2015 was a banner year for API's blog. 56 posts covered everything from advanced ceramics to delay lines to cyber security, garnering thousands of views and hundreds of likes. Here are API's top 6 most popular blog posts of the year:

6. Introducing Delay Lines Week

API’s extensive catalogue of delay lines offer a range of semi-standard and customizable topologies that feature wide bandwidths and low insertion loss. Our BAW (Bulk Acoustic Wave), SAW (Surface Acoustic Wave), Lumped Constant, Steel Dispersive, and Coaxial - High Frequency delay lines are available in a variety of package sizes and interface options, ensuring that our customers will get the best solution for their individual needs. All this week, we will be exploring the many features and applications of our delay lines and what they can offer to customers that require both high performance as well as high reliability. 

5. API's Filter Mitigates BAS Interference for Major Telecom Company

Over the years, API Technologies has built a solid reputation among wireless service providers by solving even the most challenging interference issues. API's range of filter designs for the telecomindustry offer a host of customizable topologies and models that can be modified and adapted to meet the specific needs of the customer. One such customer, a major telecom company, struggled with significant and persistent issues concerning Broadcast Auxiliary Service (BAS) interference in Electronic News Gathering (ENG) trucks. After several other companies tried and failed to rectify the situation, the telecom company engaged API Technologies. The result? Find out in this case study.

4. Ceramics Week: API Helps Save Lives with Custom Engineered Ceramic Assemblies

API Technologies has re-engaged with a leader in medical device manufacturing by supplying ceramic assemblies for the next generation of pacemaker designs for their internal defibrillator program.  Through a solid development program and our previous experience with the medical device pioneer, API’s EIS group will support the program with their custom engineered solutions to be included in their devices.  The integrated planar housing assembly will be a crucial component in the overall design and these new pacemakers will save lives!  API is extremely proud of this development and will continue to keep pace with the industry and its advancements and look forward to being a key element in the future of medical applications. 

3. Delay Lines Week Meet the Team: Mike Schweyer, SAW Product Line Manager
