Smart facial recognition is now available at Rutronik UK

Fri, Nov 27, 2020

Distributor Rutronik UK is now stocking the Smart Panel PC MM8 from Holitech. It has intelligent face recognition and sensor-controlled temperature recording. The Smart Panel PC integrates into existing systems for secure access management.

The touch display, 2Mpixel camera, loudspeaker and temperature sensor are integrated in the housing. Data synchronisation is carried out via specially developed software on an external server connected to the MM8 via a network. The values are processed and, depending on the organiser’s specifications, appropriate commands are returned to the device. For the output of commands to external devices both an RS-232 and Wiegand interface are available.

Recognition time is less than 0.5 seconds, via the binocular infra red camera. The panel PC compares biometric data based on a stored profile and detects changes in a person. Photo or video material is distinguished from real people to deny unauthorised visitors access. There is an intelligent voice output and the display can also act as an information board, advises Rutronik.

The MM8 can be used as an internal access management system, using an optional smart card reader with a response time of 0.2 seconds, ISO14443A and cloud connection to track visitor presence in real time.

There is also a standalone version that is not connected to an external server. In this model, the internal memory scores with 8Gbyte, which has space for the data of over 100,000 people. The USB interface allows easy data extraction for internal analysis.

The fast, intuitive interaction capabilities of the MM8 make it suitable for public transport, airports, hospitals and care facilities, as well as for company access management and access for events.

Rutronik UK has a team of highly qualified UK employees with a broad experience of the electronics industry. Its parent company, Rutronik Elektronische Bauelemente, is the third largest distributor in Europe and number 11 worldwide.

The broadline distributor supplies semiconductors, passive and electromechanical components as well as boards, storage, displays and wireless products. The company‘s primary target markets are the automotive, medical, industrial, home appliance, energy and lighting industries.

FlyFocus uses Vicor DC/DC converter for heavier payloads in CableGuard UAV

Thu, Nov 26, 2020

A detachable tethered unmanned aerial vehicle (UAV) developed by FlyFocus is for mission critical surveillance. When tethered, it hovers at an altitude of 70m for extended periods. It can also be used in remote command more, when the tether cable is detached, allowing the UAV to track a suspicious object for up to 30 minutes.

The UAV includes a Vicor DCM DC/DC converter to enable heavier payloads or longer flight times.

At 5kW, the UAV is rated as the most powerful tethered type available on the market today. Vicor’s isolated, regulated DCM DC/DC converters are used in the power delivery network from the tether cable to the drone’s motors and electronics.

In tethered mode, the UAV’s electric motors and on-board electronics are powered via the tether cable, which delivers 400V DC from the ground station. This lets it perform surveillance virtually indefinitely, with only occasional landings for maintenance inspections. When the UAV untethers for free flight, on-board batteries seamlessly take over the vehicle’s power supply, allowing up to 30 minutes’ flight with a single daylight camera payload, and 20 minutes with a dual thermal plus daylight camera set-up.

FlyFocus uses the high 5kW of power available through the tether cable. The drone’s eight motors can be safely landed even with two motors disabled, says FlyFocus. The UAV’s two cameras are a full HD type with 10x optical zoom and 4x digital zoom, and a night vision IR 640p camera with 4x digital zoom.

Vicor isolated, regulated DC/DC converters can buck the tether cable’s 400V DC down to the UAV’s operating voltages; accommodating this high voltage reduces cable current and I2R losses. It also allows a much smaller, lighter cable to be used.

The increased power capacity allows FlyFocus to use heavy cooled thermal cameras, or cameras with enhanced zoom and also allow additional payload modules.

According to Vicor, the DCMs’ power density allows eight 600W modules to be packed into a space-limited pod under the UAV, with just two heatsinks or fans.

Tyre sensor combines monitoring for smart tyres

Wed, Nov 25, 2020

Tyre status and loading monitoring is possible, together with pressure sensing in the MLX91805 smart tyre sensor from Melexis. OEMs can use the sensor to prepare for the extension of mandatory tyre pressure monitoring to include commercial vehicles and to enable future generations of smart tyres, says the Belgium-based engineering company.

Unlike conventional, rim-mounted tyre pressure monitoring sensors (TPMS), the MLX91805 has been specially designed to be embedded in the tyre. It integrates an 800g XZ-axis accelerometer that senses up to 10,000 samples per second. It also integrates a pressure sensor, together with temperature and voltage sensors.

The MLX91805 is suitable for tyres used on commercial vehicles, including heavy duty ones, as well as for passenger cars. EU regulations on tyre pressure monitoring for heavy duty commercial vehicles is due to come into force some time between 2022 to 2024. The multiple sensors in the MLX91805 will help ensure compliance and provide extra information, such as loading, that can extend tyre life and boost fuel economy and safety, says Melexis.

The sensor integrates a low power, 16-bit microcontroller and a 315/433MHz RF transmitter that draws just 5mA at 5dBm output power and with just 90nA sleep current. It can run from a tiny battery for the life of the tyre, says Melexis. In addition to built-in diagnostics and fault detection, a maths co-processor allows fast and energy-efficient digital signal processing.

Melexis also offers a library to help application-level software capture and interpret the key information, like accelerometer signals, of the tyre footprint area, to enhance design development.

The MLX91805 is available in a 5.0 x 4.0mm DFN14 package.

Ivan Zagan, product manager for tyre monitoring sensors at Melexis, observed: “This world-first device lets tyre manufacturers create the next generation of smart tyres to deliver extra value for owners and operators, enable new services to maximise fuel efficiency and safety, and contribute to the development of self-driving vehicles.”

MCUs are validated for security, says NXP

Tue, Nov 24, 2020

Microcontrollers (MCUs) from NXP Semiconductors have received Level 2 certifications by both the PSA Certified scheme co-developed by Arm and the GlobalPlatform Security Evaluation Standard for IoT Platforms (SESIP) using the secure protection profile for embedded processors. The LPC55S16 MCU is intended for IoT and Industrial edge applications, device security and data protection.

The LPC55S16 MCU is part of the NXP EdgeVerse computing and security portfolio and a member of the general purpose LPC5500 MCU series based on the Arm Cortex-M33 core. The MCU series is based on 40nm NVM process technology, and offers advanced security and mixed-signal capabilities.

The LPC55S16 MCU achieved PSA Certified Level 2, based on an assurance framework to showcase robustness of the security. The certification enables device manufacturers to reduce additional security testing and improve time to market. The laboratory evaluation against the PSA Root of Trust (PSA-RoT) security claims to demonstrate that the device can protect against scalable software attacks.

To achieve GlobalPlatform SESIP 2, the LPC55S16 MCU underwent source code analysis and penetration testing and was validated by an independent certification body. SESIP certification helps assure product security claims are tested and verified, and provides evidence of the LPC55S16 MCU’s resistance to basic attack potential. SESIP allows for customers to re-use the LPC55S16 MCU validation results in the certification process for their end applications.

The LPC55S16 MCU integrated security features include Arm TrustZone technology, which enables system-wide software protection with the ability to securely isolate peripherals to reduce the risk of attack on critical components. There is also an AES-256 accelerator which provides confidentiality and a secure hash algorithm (SHA2) accelerator provides integrity of secure communications and secure boot. A Prince module offers real-time encryption and decryption of the on-chip flash to provide both secure storage of data and asset protection of software IP.

The Casper Crypto co-processor enables hardware acceleration of various asymmetric cryptographic algorithms to establish secure connections, while a physical unclonable function (PUF) uses dedicated on-chip SRAM to construct unique device root keys (64 to 4096 bits) for secure storage. Other protection features are a 128-bit unique device serial number for identification (UUID) and a true random number generator (TRNG). A code watchdog enables integrity checking of execution flow of the firmware and a debug authentication protocol is provided for secure debugging.

The LPC55S16 MCU is part of the Certified EdgeLock Assurance program. Both the SESIP and PSA Certified testing and certifications were conducted by the independent security evaluation laboratory, Brightsight.

The i.MX LPC55S16 MCU family is available now.
