Smartphone app scans pupils to detect concussions

We’ve seen a number of promising breakthroughs when it comes to detecting concussion, such as systems that track eye movements in search of symptoms and blood tests that can pick them up seven days after the incident. Knowing whether an athlete has suffered a concussion or not is important, because if left untreated it can not only lead to immediate consequences like headaches and memory loss, but further knocks to the head can pose even graver, long-term health risks.

So a smartphone app that can be used on the sideliness to immediately screen for concussion would be a game-changer, and that is exactly what researchers at the University of Washington (UW) have set out to develop. Called PupilScreen, the technology works by tracking the pupil’s response to light, something known as the pupillary light reflex, which is a technique already used to gauge traumatic brain injuries.

Demo: Inuitive NU4000 SoC with ARC EV Processor Running SLAM and CNN

Sponsored by Synopsys

Autonomous vehicles, robotics, augmented and virtual reality all require simultaneous localization and mapping (SLAM) to build a map of the surroundings. Combining SLAM with a neural network engine adds intelligence, allowing the system to identify objects and make decisions. In this demo, Synopsys ARC EV processor’s vision engine (VPU) accelerates KudanSLAM algorithms by up to 40% while running object detection on its CNN engine.

New package technology improves EMI and thermal performance with smaller solution size

Sponsored by Texas Instruments

Power supply designers have a new tool in their effort to achieve balance between efficiency, size, and thermal performance with DC/DC power modules. The Enhanced HotRod™ QFN package technology from Texas Instruments enables engineers to address design challenges with an easy-to-use footprint that resembles a standard QFN. This new package type combines the advantages of flip-chip-on-lead with the improved thermal performance presented by a large thermal die attach pad (DAP).

Benefits of FPGAs & eFPGA IP in Futureproofing Compute Acceleration

Sponsored by Achronix

In the quest to accelerate and optimize today’s computing challenges such as AI inference, our system designs have to be flexible above all else. At the confluence of speed and flexibility are today’s new FPGAs and e-FPGA IP. In this episode of Chalk Talk, Amelia Dalton chats with Mike Fitton from Achronix about how to design systems to be both fast and future-proof using FPGA and e-FPGA technology.
