How does SLAM help autonomous vehicles?
SLAM (simultaneous localization and mapping) is used in autonomous vehicles of all types to build a map and simultaneously locate the vehicle in that map. SLAM algorithms allow the vehicle to analyze and map out unknown environments. With this map information, the vehicle can implement path planning and obstacle avoidance. Visual SLAM uses cameras and/or […]
Snap-in aluminum electrolytic caps handle 600 Vdc
The 380LX and 381LX series of aluminum electrolytic capacitors now include voltages up to 600 Vdc. The new ratings are designed to serve industrial electronics customers who continue to push the application boundaries for these components into higher voltages. The 380LX and 381LX snap-in series are among the industry’s top performers with a published load […]
Smart buildings and the IoT: Zoning systems
There are significant benefits to moving some decisions in smart HVAC systems close to the application and away from the cloud. Asem Elshimi, Silicon Labs We’ve probably all experienced an office environment that always felt too cold or hot no matter the weather. And we’ve all experienced the fruitlessness of asking the building facilities team […]
Compact intelligent power modules target home-appliance power inverter apps
Infineon Technologies AG adds a new member to the CIPOS Tiny Intelligent Power Module (IPM) family: the CIPOS Tiny IM323-L6G 600 V 15 A. The new IPM is based on TRENCHSTOP IGBT RC-D2 switches and state-of-the-art SOI gate driver technology to realize maximum efficiency and improved reliability, along with minimized system size and cost. The […]
Positioning in 5G NR – A look at the technology and related test aspects
Positioning technologies will continue to play an essential role in future wireless communications systems. The influence of these technologies is transitioning from a “nice-to-have” approach in legacy networks, where positioning is supported as an additional service, to a “must-have” approach requiring resilient and reliable provisioning of location estimates that play a central role in the…
Orchestration at the edge reduces network latency
Edge computing brings benefits to users by reducing network latency, thus improving services, but needs management orchestration. Here, we demonstrate how orchestration improves latency in an automotive edge-computing use case be reallocating network resources. Multi-access edge computing (MEC), commonly called “edge computing,” moves data processing to the edge of communication networks. Bringing computing close to…
Why I’m divided on “Right to Repair”
Mandating a “right to repair” seems like a good idea, but what are the details and risks? As an engineer, I like to fix things, or at least try to. That’s why I have been following the “right to repair” (RTR) movement, which is getting a lot of attention these days (just Google it and […]
Neural net processing IP includes automatic algorithm partitioning
Addressing increasing performance requirements for artificial intelligence (AI) systems on chip (SoCs), Synopsys, Inc. announced its new neural processing unit (NPU) IP and toolchain that delivers the industry’s highest performance and support for the latest, most complex neural network models. Synopsys DesignWare ARC NPX6 and NPX6FS NPU IP address the demands of real-time computing with ultra-low power consumption for […]
The difference between signal under-sampling, aliasing, and folding
Most engineers today are sensitive to problems that arise when digital measurement instruments try to capture signals containing frequencies that are too high for the sampling circuitry to handle–undergrad EE programs typically cover Nyquist’s sampling theorem. Nevertheless, there are terms associated with sampling problems that sometimes get confused. Probably the three concepts most likely to […]
