By Dustin Seetoo, Director of Product Marketing, Premio Inc. Deep learning for autonomous vehicle systems requires a blended software and hardware strategy In-step deep learning training and inference Deep learning training and deep learning inference are very different processes, each with a specific role in developing more advanced autonomous driving systems. Deep learning training taps […]
FAQ
Automobile Hands-Off Detection, Part 4: Capacitive solutions
Cars with lane-keeping assistance (LKA) also are mandated to have a hands-off detection (HOD) function; there are several ways to meet this challenging requirement. Despite the BOM advantages of torque-based HOD, it has performance issues. Capacitive-based sensing is a viable alternative approach. Capacitive sensing for HOD monitors the driver’s grip on the steering wheel by […]
Automobile Hands-Off Detection, Part 3: Torque solutions
Cars with lane-keeping assistance (LKA) also are mandated to have a hands-off detection (HOD) function; there are several ways to meet this challenging requirement. The previous part of this article discussed the need for hands-off (or on) detection (HOD) and its connection to the lane-keeping assistance feature in today’s cars. This part will look at […]
Automobile Hands-Off Detection, Part 2: Requirements
Cars with lane-keeping assistance (LKA) also are mandated to have a hands-off detection (HOD) function; there are several ways to meet this challenging requirement. Where does “hands-off detection” (HOD) come into the picture? (Note: “hands-off detection” is sometimes spelled out as “hands-on detection;” fortunately, the acronym is the same either way.) It is a feature […]
Automobile Hands-Off Detection, Part 1: Basic issues
Cars with lane-keeping assistance (LKA) also are mandated to have a hands-off detection (HOD) function; there are several ways to meet this challenging requirement. Today’s cars are packed with all sorts of functions, features, and attributes that didn’t exist – or need to – just a few years ago. Whether for driver and passenger convenience, […]
LoRaWAN IoT networks help tame temperature-sensitive applications
The need to chill vaccines reliably during their trip cross country has highlighted the value of LoRaWAN-enabled sensors and networking. Chris Boorman, Laird Connectivity Ordinarily, cold supply chain wouldn’t be a dinner table conversation. COVID-19 vaccines, of course, have changed the situation. Specialized refrigerated containers, refrigerated vehicles, and ultra-cold storage warehouses are the foundation for […]
MCUs for ADAS – what’s the difference?
The emergence of advanced driver assistance systems (ADAS) is changing how designers use and specify microcontrollers (MCUs), but it’s only one dimension of the changes occurring in the design of automotive systems (Figure 1). This FAQ will begin with the basics of AEC-Q100 requirements for automotive integrated circuits – those requirements are not going away […]
Managing smart street lighting design
Wi-SUN may well be the linchpin that turns street lighting into a scalable IoT umbrella offering a multitude of solutions beyond illumination. Soumya Shyamasundar, Silicon Labs According to the World Bank, legacy street lighting systems based on traditional technologies can account for as much as 65% of a city’s electricity consumption. The energy consumption, of […]
MCU specification considerations for robotics
Robotics platforms have unique needs where microcontroller (MCU) performance is concerned. MCUs that have been optimized for use in robots often incorporate multiple functions, including built-in internet protocol (IP) connectivity, safety and security functions, and advanced control algorithms. Integrating an MCU core with a field programmable gate array (FPGA) is another approach to achieving optimized […]
Nuances of low power MCUs for wireless sensors and wearables
The optimization of microcontrollers (MCUs) in power-sensitive applications such as wireless sensor nodes and wearables is all about maximizing power management effectiveness. To minimize power consumption, low-power MCUs typically operate at frequencies below 50 MHz, compared with hundreds of MHz or even 1+ GHz for conventional MCUs. These power-optimized MCUs also use low-power peripherals; they […]
