Tue, Mar 09, 2021

Image sensor modules and image signal processing core have been added to the mVision 2.0 stack for low power embedded vision systems by Lattice Semiconductor. This latest version has multiple updates to accelerate the design of embedded vision applications for industrial, automotive, medical, and smart consumer systems. There is also support for popular new image sensors used in industrial and automotive systems and an image signal processing IP core and reference design to help developers design smart vision applications at the edge. The stack also includes support for the Lattice Propel design environment to simplify development of vision systems with an embedded RISC-V processor.

The updates broaden mVision support for popular image sensors used in industrial and automotive markets. They are also claimed to simplify hardware and software design with a drag-and-drop Propel design environment. Additional development boards and reference designs are powered by Lattice’s FPGA for embedded vision, CrossLink-NX.

Lattice CrossLink-NX devices with integrated hard MIPI support and low power consumption can be used in camera applications operating at the edge. “Using CrossLink-NX with an embedded RISC-V processor enables a more compact and efficient ISP implementation,” said Arndt Bussman, CTO at Helion, which has partnered with Lattice to provide optimised ISP solutions.

The stacks are designed to help customers adopt emerging technologies by providing a comprehensive collection of ready-to-use software, IP, hardware demos, and reference designs to help them quickly deploy applications like embedded vision in current and future product designs, explained Mark Hoopes, director of industrial segment marketing, Lattice Semiconductor.

Lattice has added new development boards supporting popular image sensors for industrial and medical applications to the mVision stack, expanding support for automotive, industrial, and medical embedded vision applications. Image sensors that are supported include the Sony IMX464 and IMX568 and the AR0344CS from ON Semiconductor.

The Propel design environment tool includes a complete set of graphical and command-line tools to create, analyse, compile, and debug both the hardware design of an FPGA-based processor system, and the software design for that processor system.

Lattice has also expanded the Lattice ISP reference design.

At the same time as the mVision announcement, Lattice also revealed extended capabilities for its Sentry stack. The latest version of its secure system control stack, Sentry 2.0 enables hardware root-of-trust (HRoT) solutions compliant with NIST Platform Firmware Resiliency (PFR) Guidelines (NIST SP-800-193) and supporting 384-bit encryption.

Lattice Sentry 2.0 supports firmware security for the communications, computing, industrial, automotive, and smart consumer markets, says the company. It provides developers an efficient and secure way to quickly implement enhanced system and cryptographic applications.

Gateway uses Wireless M-Bus technology to gather meter readings

Mon, Mar 08, 2021

Data can be collected autonomously from Wireless M-Bus meters or sensors using the WebdynEasy W M-Bus data concentrator by Webdyn.

The W M-Bus point-to-point radio protocol uses the 868Mhz band, traditionally used in smart metering and smart buildings, because of its relatively moderate power consumption, said Webdyn.

The Wireless M-Bus standard protocol is based on a private, non-operated network. In order to operate, a Wireless Mbus network requires hubs (or gateways) that allow connection between all the sensors and a remote information system. In free field, the distances that can be potentially covered between a sensor and the hub are of the order of 1km.

The WebdynEasy W M-Bus data concentrator functions as a standalone collection point for data from meters or wireless M-Bus sensors. The gateway retrieves all the data collected at a single point so that it can be sent to the chosen information system.

The energy-efficient hub’s battery service life can exceed 10 years. Webdyn has also developed the WebdynEasy application, which is free to download from the PlayStore. The Bluetooth Low Energy function eases configuration and installation, added the company.

Once installed, the product is autonomous in energy and the deployment can start automatically or using a magnet.

Depending on the configuration, the hub uses regular listening windows to record the frames emitted by the meters and W M-Bus sensors. The hub regularly uploads data files to the FTP server using the cell phone or LTE-M network.

Webdyn’s strategy is to offer a complete range of dataloggers covering all smart grid, smart metering, smart building and smart cities markets.

Webdyn designs and industrialises hardware and software solutions for M2M communication for the energy, environment, smart grids and transport markets.

Webdyn supplies multi-protocols concentrators, covering all the applications of teleservice and the monitoring. It has expertise in endpoints RF and gateways PLC-G3.

Industrial Mini-ITX carrier is designed for COM Express Type 10 mini modules

Mon, Mar 08, 2021

The ITX-M-CC452-T10 carrier board has been designed by Winsystems for Type 10 mini module designs and COMeT10-3900 cards.

This is the company’s first Mini-ITX form factor carrier board to complement and support its COMeT10-3900 COM Express Type 10 mini modules. The ITX-M-CC452-T10 carrier platform has industrial components for testing products in development. The reliable carrier board operates at a temperature range of -40 to +85C degrees and with a wide input range of 5.0 to 20V DC.

The industrial COM Express carrier can be used by as a reference point to test and troubleshoot customers’ own or another COM Express Type 10 carrier design, explained George T Hillard, technical sales director, Winsystems. “And, because it supports all interfaces from our recently introduced COMeT10-3900 COM Express modules, these two products can be readily deployed as a complete embedded edge computing platform,” he added.

As an industrial-rated reference board, the ITX-M-CC452-T10 carrier is designed to operate over the full specifications of the COMeT10-3900 COM module so the combination can be proven at temperature. The carrier features dual Ethernet (USB 3.0 and 2.0), four serial ports, three Mini-PCIe expansion options and multiple display options. These are increased when the board is combined with the COMeT10-3900 Express module.

The carrier also has multiple processor options for single, dual or quad CPU cores and various RAM and on-board solid state device (SSD) sizes.

The ITX-M-CC452-T10 carrier supports up to two independent displays: one DisplayPort with 4K resolution and one LCD with backlight and touch control. Additional connectivity and I/O capabilities include four GPIs and four GPOs. There is also built-in storage for microSD, SATA and mSATA.

“The ITX-M-CC452-T10 COM carrier satisfies the rigorous quality and security imperatives for Industrial IoT applications within the medical, industrial automation, military/aerospace and transportation markets,” said Hilliard. “Equally important, it provides product designers with abundant connectivity to distinguish their products in the market and the cost-effectiveness and predictable delivery they require to reduce development risk.”

The ITX-M-CC452-T10 carrier board is supported with technical guidance and BIOS customisation. The ITX-M-CC452-T10 Mini-ITX form factor carrier will become available Q1, 2021, and will ship with access to the accompanying product manual, a carrier design guide, COM modules and thermal solutions (the latter two items sold separately).

ISO 17025-certified sensors protect drugs in transit

Mon, Mar 08, 2021

Calibrated and ISO 17025-certified temperature, and humidity and temperature sensors from Sensirion are used by customers to achieve cost-efficient GDP-compliant supply chain monitoring of drugs, vaccines and perishable goods.

Highly regulated products, such as pharmaceutical or perishable goods, typically require special handling along their distribution chain to comply with directives. Manufacturers need to adapt to ensure they adhere to current good distribution practices.

Temperature is the most regulated parameter and determines the lifetime of the product and usability of a product. Reliable temperature monitoring requires reliable dataloggers, which are increasingly changing, for example, the introduction of EN 12830 and accepted only with certification from accredited laboratories (ISO 17025). Dataloggers typically have several electronic components and often analogue temperature sensors, which makes accredited calibration of the complete device necessary. This step take time and adds expense but could be avoided using temperature sensing strategies, said Sensirion.

The STS32 and STS33 digital temperature sensors are ISO 17025-certified and optimised for cold and frozen chain applications. Both rely on CMOSens technology, which is claimed to enable increased computational power, reliability and improved accuracy specifications compared to earlier temperature sensors. The sensors have enhanced signal processing, two distinct and user-selectable I2C addresses and communication speeds of up to 1MHz.

The DFN package has a footprint of 2.5 x 2.5mm2 and a low height of 0.9mm.

Every STS32 or STS33 is identified by a unique serial number and is supplied with an ISO 17025-accredited calibration certificate. The calibration certificate comprises three temperatures, -30, +5 and +70 degrees C. In addition to the certified temperature sensors, Sensirion has introduced the SHT33 humidity and temperature sensor. This is based on the proven SHT3x series and is claimed to offer high accuracy and quality standards combined with ISO 17025-certified temperature sensing on one chip.

Calibration certificates and data for the STS32, STS33 and SHT33 sensors are available for download. STS32 users can not only embed sensor hardware into a product but are also merge the calibration data from the sensor with the calibration information needed for dataloggers. This simplifies the manufacturing process, as the typically expensive and time-consuming calibration of the assembled device is replaced and completely covered by using a digital, pre-calibrated temperature sensor, while meeting the stringent quality requirements of pharmaceutical and medical industries.
