  1. Thermal Stereo Vision Makes Safer Cars
    9/17/2019

    Thermal stereo cameras are beneficial for partial autonomous systems like automatic emergency braking (AEB) by making them more reliable and safer. Not only could the thermal stereo camera theoretically tell the vehicle’s computer system to slow down upon detecting an object in the road in any lighting condition, it could also provide redundant distance data, along with the vehicle’s visible camera and radar systems, to ensure the vehicle makes the most appropriate decision for the circumstance.

  2. Mastering The View Into Tricky Environments: Find Your Answer In Fiber Optics
    9/16/2019

    Glass imaging fiber optics offer a versatile way to see into hazardous environments, allowing cameras to be kept in safe places or providing an all-optical backup view that doesn’t require power.

  3. PEEK, PEI, LSR, And Other Material Options For Medical Prototyping
    9/11/2019

    Developing parts for the medical device industry is a high-stakes process, and material choice is an important decision to make at the outset of the project. Five strong contenders include PEEK, PEI, and PPSU; polycarbonates; medical-grade liquid silicone rubber; and 3D-printed titanium and ABS-like WaterShed XC 11122. The specific requirements for the part or device being developed will help steer the decision on which material option is the best choice.

  4. Why ADAS And Autonomous Vehicles Need Thermal Infrared Cameras
    8/28/2019

    Safe advanced driver assist system (ADAS) vehicles and autonomous vehicles (AV) require the use of sensors to deliver scene data adequate for the detection and classification algorithms to autonomously navigate under all conditions. This requirement cannot be adequately met with just visible cameras, sonar, and radar sensors, as they do not meet many safety concerns in real conditions. Thermal, or longwave infrared (LWIR), cameras can detect and classify pedestrians in darkness, fog, and sun glares, delivering improved situational awareness in ADAS and AV. This white paper discuses why thermal infrared cameras are a necessity for autonomous driving.

  5. Use Color Matching To Customize Molded Parts
    8/28/2019

    Product designers often need their manufacturing suppliers to produce plastic injection-molded parts that are Pantone color-matched to company specifications. Protolabs' injection molding service offers custom color matching on customer-provided Pantone numbers and on customer-provided part samples.

  6. High-Speed Imaging Techniques For The Aerospace Industry
    8/15/2019

    For many years high-speed imaging has been used in various applications by engineers in the aerospace industry. Three very common imaging techniques utilized by these engineers are Digital Image Correlation, Particle Image Velocimetry, and Schlieren Imaging. These imaging techniques provide engineers with great insight into various aspects of the strength and durability of materials, the characteristics of engine combustion processes, the aerodynamics of objects in flight, and much more.
