Integrity launches first MA for V2X ecosystems

Mon, Jan 14, 2019

Believed to be the first misbehaviour authority service (MAS) for the US V2X (vehicle to everything) ecosystem, Integrity Security Services (ISS) has announced that its MAS will begin by serving subscribers already subscribing to its all certificate management service (CMS).

All new and existing ISS CMS subscribers will be able to begin identifying vehicles for misbehaviour and removing them from their networks. Device manufacturers and all subscribers can contact Integrity for certification and to enable the device with the ISS-approved MAS OBU client and begin testing.

The ability to identify vehicles that are not sending correct V2X messages and to remove them from the connected vehicle ecosystem is an important security requirement to maintain trust in the ecosystem. ISS claims that its MAS provides this capability on a scalable and efficient national level. ISS will be publishing its misbehaviour detection criteria, reporting format and MAS APIs for OBU and RSU vendors to use with their compliant systems.

Integrity Security Services was established to provide best practice embedded security products and infrastructure solutions for protecting smart devices from cyber security attacks. End-to-end automotive solutions range from ECU cryptographic platforms to large-scale public key management systems.

I2C interface makes low power CO2 sensor easier to implement

Mon, Jan 14, 2019

In smart environments where sensors monitor for changes so that the appropriate actions can be taken, the fastest growing examples are smart homes and smart offices where a network of sensors monitors temperature and carbon dioxide (CO2) levels to ensure the optimal conditionals are maintained with the minimum of energy expenditure, for example heating ventilation and air conditioning (HVAC) and indoor air quality (IAQ). A challenge for such systems in that the CO2 sensors need mains power to operate incurring costs for cabling and, in the case of installing in existing buildings, redecoration. Gas Sensing Solutions (GSS) believes it has solved this problem with its low power, LED-based sensor technology. The sensor’s power requirements are so low that wireless monitors can be built that measure CO2 levels as well as temperature and humidity with a battery life of over 10 years. As they are wireless they can be placed wherever they are required with no need for cabling or disruption. Equally, they can be simply relocated as building usages changes.

GSS has added an I2C interface to its very low power CO2 sensor, the CozIR-LP to make the integration of the sensor into a design very easy, says GSS. The CozIR-LP is claimed to be the lowest power CO2 sensor available. It requires only 3mW – this is up to 50 times lower than typical NDIR CO2 sensors. The patented LED technology also means that the solid state sensor is very robust, adds GSS. This keeps maintenance costs to a minimum as the expected lifetime is greater than 15 years; making them particularly suitable for applications that measure low (ambient) levels of CO2 from 0 to one per cent.

GSS will be launching the new I2C-enabled CozIR-LP on booth C5366 at the AHR Expo in Atlanta, GA, USA (14 to 16 January 2019).

Analog Devices and Momenta partner for HD maps in autonomous vehicles

Fri, Jan 11, 2019

High definition (HD) maps are a critical element of autonomous driving and must deliver accurate, real-time information to help safely guide the vehicle to its destination. Announcing a collaboration with Momenta, an autonomous driving technology company based in China, Analog Devices will develop HD maps in autonomous vehicles. Analog Devices’ inertial measurement units (IMUs) will be used to improve the mapping system and technology upgrades in Momenta’s L3 freeway ramp-to-ramp and L4 full autonomy driving mapping software.

Under poor weather conditions, or when a GPS signal is lost, an IMU delivers mapping output. Analog Devices’ IMUs will enhance Momenta’s mapping software to meet the demanding accuracy requirements of HD maps. Analog Devices points out that its IMUs exceed the value/performance ratio of higher cost alternative sensors based on fibre optic gyro or laser gyro technologies.

Momenta’s vision-based semantic HD maps are crowdsourced, highly accurate and frequently updated. They provide map update and localisation services. Momenta is also able to leverage modules mounted on taxis, trucks and buses to create a

Momenta’s team includes experts on computer vision and deep learning, including one of the authors of Faster R-CNN and ResNet, the influential deep learning network.

Analog Devices has more than 30 years of experience in MEMS inertial sensor design. Its MEMS IMUs have been applied in the avionics and smart agriculture sectors, which have similar requirements to those for autonomous driving. Analog Devices’ MEMS IMUs are capable of maintaining critical specifications such as bias, sensitivity, and cross-axis sensitivity under all conditions, including time variation, shock, vibration, and temperature conditions.

SoCs deliver video warping for sharp images in digital signage

Fri, Jan 11, 2019

SoCs from Omnitek are designed for video warping in the small projector and digital signage markets. The Flex SoCs are shipping now, after debuting at CES in Las Vegas this week.

The Flex 2K for 2K video (2048 x 1200) and Flex 4K for 4K video (4096 x 2400), both operate at up to 60 frames per second. Both perform a set of image geometry correction functions on a video stream, including rectilinear or arbitrary image warps and 360 degree rotation, as well as edge blending. These characteristics make them suitable for projector image correction and projection of a single large image from multiple projectors. Additionally, they can be used for camera lens correction, such as fish-eye lens distortion, explains Omnitek. The real-time response of the Flex 4K extends its suitability to virtual reality (VR) and augmented reality (AR) applications.

The SoCs are based on FPGA technology and are programmed as fixed-function parts and supported by evaluation boards, reference software and datasheets. No FPGA design skills are required to use them confirms Omnetek.

Roger Fawcett, CEO, Omnitek, explained the choice of FPGA technology: “Since the Flex devices are FPGA based, we can offer those customers our customisation service with a rapid turnaround to enable them to get differentiated products to market quickly,” he said.

Omnitek designs intelligent video and vision systems based on programmable FPGAs and SoCs. Design services are combined with optimised FPGA intellectual property (IP) cores covering high-performance video / vision and artificial intelligence (AI) / machine learning enable the company to provide cost-optimised solutions to a range of markets. Omnitek also designs and manufactures a suite of video test & measurement equipment.
