The death of transformers? AC Direct DC Enabler is a solid-state solution for AC-DC power supplies

Amber Power Silicon 20x10mm

Power supplies would typically transform AC mains to DC voltage with the use of transformers, rectifiers, or filtering, but Amber Solutions’ AC Direct DC Enabler chip claims to do without those old tech electromechanical components by enabling DC extraction directly from AC mains through solid-state architecture. The company claims the technology leads to dramatically smaller size footprints, while simultaneously “delivering a much more dynamic, configurable power delivery capability”. Consumer, commercial and industrial electrical products manufacturers and semiconductor companies can already evaluate the technology as the AC Direct DC Enabler is now available as a demo kit. The company made bold claims even announcing the death of transformers: The magic of the Amber AC Direct DC Enabler is that it allows manufacturers to add modern intelligence and enhanced functionality to new and existing products using much smaller silicon chips to manage and deliver DC power. Using a single silicon chip, this […]

Intel Mobileye EyeQ Ultra RISC-V processor targets Level 4 autonomous driving

Mobileye EyeQ Ultra

Let’s carry on with Intel’s CES 2022 news, but with a twist as Mobileye EyeQ Ultra does not include any x86 cores, but instead, the automotive processor features 12 RISC-V cores, Arm GPU and DSP, and aims to bring Level 4 autonomous driving to cars thanks notably to a 176 TOPS AI accelerator. The company says EyeQ Ultra packs the performance of 10 EyeQ5s in a single package, with the single chip solution avoiding the power consumption and costs related to integrating multiple SoCs together.   Intel Mobileye EyeQ Ultra specifications highlights: CPU – 12 RISC-V CPU cores  (24 threads) GPU – Unnamed Arm GPU DSP – Unnamed Arm DSP SIMD cores VLIW cores Coarse grained reconfigurable array (CGRA) cores CNN accelerator clusters Two sensing subsystems One camera-only system Radar and Lidar combined system 5-nanometer process technology Mobileye provides both the chip and software with for instance high-definition map and […]

Intel unveils Alder Lake desktop and mobile IoT processors

Intel Alder Lake-H Mobile IoT processsor

Intel introduced high-end Alder Lake Hybrid processor family for consumer devices a couple of months ago, with Pentium G7400 and Celeron G6900 leaking a few weeks later, and now the company has formally announced the Alder Lake-S and Alder Lake-H processor families for respectively desktop IoT and mobile IoT solutions, as well as more efficient U-series and P-series of 12th Gen Intel Core Alder Lake IoT processors with a TDP ranging from 15W to 28W. Alder Lake S-Series desktop processors for IoT Key features and specifications: CPU Up to 16 cores, up to 24 threads in IoT SKUs Up to 30 MB Intel Smart Cache TDP – 35W to 65W Real-time capability on select SKUs Graphics/Video Intel UHD Graphics 770 driven by Intel Xe architecture with up to 32 EUs Up to four independent displays up to 4K or one display at 8K resolution Up to two video decode boxes […]

Onera Health unveils Onera Biomedical-Lab-on-Chip with over a dozen sensor inputs

Onera Biomedical Lab-on-Chip

Onera Health, a Dutch-American MedTech company has just introduced the Onera Biomedical-Lab-on-Chip, an ultra-low-power biosignal sensor hub for wearable health, following their earlier work on sleep diagnostic solutions. The Arm Cortex-M4F based Onera ONE010 chip embeds a multi-channel sensor readout system with integrated data processing, power management, and interfacing features. It features biomedical inputs with 10 readouts for ExG, covering EEG, ECG, EMG, and EOG, 2 bioimpedance readouts, and 2 readouts for photoplethysmography, as well as digital filters and accelerators to process the data from the sensors. The microcontroller is also equipped with several standard wired interfaces such as UART, SPI, I2C, and I2S, operates from a single power source between 0.8V and 3.6V, and the company says a large amount of SRAM and embedded FLASH is available. I’ve managed to obtain a more readable block diagram and that means 320KB of SRAM and 768KB of flash. We can also […]

Solar-powered Bluetooth headset with Powerfoyle nano-material band remains charged at all times

Solar powered Bluetooth headset

Blue Tiger Solare is a solar-powered Bluetooth headset that you may never need to charge thanks to a Powerfoyle solar cell headband comprised of a “nano-material that transforms any outdoor and indoor light into clean, endless energy”. Solare Bluetooth 5.1 headset is said to be military-grade (MIL-STD-810), offers 97% noise cancellation, and is mostly designed for “road warriors” who may require a Bluetooth headset that’s charging continuously. I initially thought it would probably work better for hikers, bicycle and motorbike riders, than car drivers unless we’re talking about convertibles, but Blue Tiger caters to professional truck drivers. Solare highlights: Bluetooth 5.1 with up to ~90 meters range High-quality speaker Microphone with 97% noise cancellation Works with Sir and Google Assistant Endless Battery Life with Powerfoyle solar cell flexible headband Temperature Range – -40°C to +50°C Certifications IPX4 ingress protection rating MIL-STD-810 for extreme environments and ruggedness Solare solar-powered Bluetooth headset […]
