Image sensor is adaptive for all vehicle occupants

Fri, Sep 09, 2022

In-car safety and comfort in automotives is advanced with the VD/VB1940 DMS (driver monitoring system) sensor, a hybrid sensor for interior monitoring, announced by STMicroelectronics.

Leading automotive markets start to mandate driver monitoring systems (DMS) reported STMicroelectronics. While DMS promises greater road safety by assessing driver alertness, ST said that its next-generation dual image sensor monitors the full vehicle interior, i.e., the driver and all passengers. The sensor enables new applications such as passenger safety-belt checks, vital-sign monitoring, child-left detection, gesture recognition and high-quality video/picture recording.

The image sensor uses ST’s second-generation 3D-stacked back-side illuminated (BSI) wafer technology, which maximises the optical area and on-chip processing in relation to die size. This lets the sensor perform sophisticated algorithms locally for optimal performance in both colour and near-infra-red (NIR) imaging, saving power and relieving demand for an external co-processor.

Algorithms performed on-chip include Bayer conversion and HDR merging for optimal image-quality and frame rate. On-chip Bayerisation processing enables the user to reshuffle the colour pixels of the RGB NIR 4X4 pattern into RGGB format compatible with a range of SoCs. Local processing also handles independent colour and NIR pixel-exposure optimisation for optimum image quality in both modes, as well as smart upscaling to maximise NIR image resolution by capturing extra NIR information from RGB pixels.

The VD/VB1940 sensor combines the sensitivity and high resolution of infra red sensing with high dynamic range (HDR) colour imaging in a single component. It can capture frames alternatively in rolling-shutter and global-shutter modes. With 5.1Mpixels, it captures the high dynamic range (HDR) colour images needed for an occupant monitoring system (OMS) in addition to the high-quality NIR images typically captured by standard DMS sensors. DMS uses NIR imaging to analyse driver head and eye movements in all lighting conditions.

Offered in both bare wafers (VDB1940) and packaged in BGAs (VB1940), samples are available now and mass production is planned to meet model-year 2024 vehicles being designed now.

Qualified to AEC-Q100, the VD/VB1940 is ISO 26262 compliant to facilitate use in functional-safety systems up to ASIL-B.

ATX motherboard supports high speed computing and AI workloads

Fri, Sep 09, 2022

The ICX610-C621A has been unveiled by DFI. The server-grade ATX motherboard is designed for Intel Ice Lake, powered by the third generation Intel Xeon Scalable processors and equipped with high speed computing that can support up to 205W.

It also comes with built-in Intel Speed Select Technology (Intel SST) which provides load balancing between CPUs and multiple accelerator cards to distribute CPU resource, stabilise computation loads and maximise computing power. As a result, it improves the performance by 1.46 times compared to previous generation, said DFI.

There are three PCIe x 16, two PCIe x8 slots and one M.2 Key for computing performance that encompasses AI workload and deep learning, specifically for high-end inspection equipment, such as AOI, CT, and MRI equipment. The ICX610 also supports ECC RDIMM up to 512Gbyte 3200 MHZ for advanced inspection equipment.

For AI inference, the motherboard benefits from deep learning boost and vector neural network instructions (VNNI). According to DFI, this improves the inference for production line and medical inspection equipment by 1.56 times compared to the previous generation, for more accurate and reliable automated inspection.

Through the upgraded 10Gbits per second high speed network, large high resolution images can be quickly transmitted, accelerating the communication and co-operation between machines in machine to machine (M2M) operation.

Founded in 1981, DFI offers a range of innovative industrial computers with high quality, stability, and reliability, from industrial motherboards, single board computers (SBCs), embedded systems to industrial panel PC and displays. The company serves clients in industrial automation, transportation, energy, medicine, retail, and military applications.

Since joining the Qisda/BenQ Group in 2017, DFI has synergised its resources with Qisda and enhanced its R&D capabilities, supply chain management and production capacity. The acquisition of AEWIN and Ace Pillar in 2019 helped DFI expand its business into cyber security and develop more comprehensive solutions in smart manufacturing.

Summit SOM 8M Plus development kit extends IoT range from Mouser

Fri, Sep 09, 2022

To allow engineers to develop Laird Connectivity’s Summit system on module (SoM) 8M Plus, for IoT applications, Mouser Electronics now stocks the Summit SOM 8M Plus development kit.

The kit allows the development of advanced wireless IoT applications, including industrial IoT devices for harsh environments, IoT vision solutions, and healthcare devices.

At the heart of the Laird Connectivity Summit SOM 8M Plus Development Kit is the Summit SOM 8M Plus, which combines NXP’s i.MX 8M Plus applications processor with an NXP 88W8997 wireless SoC. The Summit SOM 8M Plus includes an integrated 2.3Toperations per second (TOPS) neural processing unit, advanced connectivity and enhanced security, providing the hardware acceleration necessary for machine learning applications. The quad-core processor can run multiple instances of Linux, including user interface and connectivity.

The Summit SOM 8M Plus development kit includes reference designs for display, camera, audio, LTE, GPS and USB 3.0 power. There are interfaces to support up to three displays and multiple options for audio, camera, video out and I/O. There is also dual-band 2×2 Wi-Fi 5 and Bluetooth 5.3 connectivity, for reliable connection, even in challenging environments, said Mouser. In addition to the security of the Summit SOM 8M Plus, the Summit Suite chain of trust offers root of trust hardware-based software validation and an upcoming FIPS (Federal Information Processing Standard) cryptographic module validation.

Mouser Electronics, a Berkshire Hathaway company, is an authorised semiconductor and electronic component distributor focused on new product introductions from its leading manufacturer partners.
