Advertorials Flexible, accurate, slim & resilient
Semitec’s Gymnastic NTC thermistor If a thermistor could be likened to any sport at the Olympics, then the Semitec JT thermistor would be a gold medal winner in gymnastics! The JT can literally bend over backwards to solve your temperature sensing problems. A worldwide winner, the Semitec JT has been used extensively in many spacesensitive applications including skin/surface sensing, various wearable technologies including bloodglucose monitors, prismatic & pouch batteries and CPU/IC monitoring. Slim but strong, the JT thermistor is only 0.5mm thick at its sensing tip (thinner than a credit card) making it the thinnest flexible NTC available world wide. The temperature sensing element is protected/laminated between two polymer layers making it flexible and resilient at the same time. This flexibility allows the JT’s sensor to be placed much closer to the heat source helping to deliver optimum temperature control. The Semitec JT can also operate in extreme temperatures from 50°C to +125°C with highly accurate 1% R25 tolerances and resistance values of 10k and 100k. In addition, the JT thermistors have excellent electrical insulation and so can be safely used where they might come into contact with adjacent live components.

Connecting Raspberry Pi to the Real World
Sequent Microsystems designs and manufactures IO Cards for Raspberry Pi. They expand the capabilities of Raspberry Pi with analog inputs and outputs (03.3V, 010V, 420mA), optically isolated inputs from 3 to 240V, onboard relays, event counters, quadrature encoders, 1K/10K thermistors, RTD sensor inputs, RTC with battery backup, RS485/MODBUS communication, MOSFET and TRIAC load drivers. All their cards use only the I2C port for communicating with Raspberry Pi, leaving all the GPIO pins available for other tasks.
Three Sequent cards (Home, Building and Industrial Automation) are "Swiss Army Knife" types, packing all the possible functions in the available space. If extra functionality is desired, each card can be stacked up to eight levels. Additional universal inputs, relays or solid state outputs can be added using compatible cards. Sequent cards can be mixed in any combination.
Buildin hardware watchdogs on all smart cards can cycle the power on Raspberry Pi to ensure that mission critical projects recover if Raspberry Pi locks up. All cards use reliable and convenient pluggable connectors and brass mounting hardware. Rated 8A/240V, the connectors oer the most flexible way of wiring Industrial or Home Automation controls.
The Sequent Raspberry Pi family is completed by a Superwatchdog with LiIon battery backup, which can keep the system running for hours in case of power failure, and a stackable Smart Fan with proportional fan control which can keep the Raspberry Pi at a preset operating temperature.

Lattice mVision Solution Stack enables 4K video processing at low power for embedded vision applications
Updated stack delivers higher ISP performance, support for LPDDR4 DRAM, and expanded hardware support for popular vision and high speed data interfaces
Lattice Semiconductor Corporation (NASDAQ: LSCC), the low power programmable leader, today announced updates to its awardwinning Lattice mVision™ solution stack. The mVision stack now supports 4K video data processing and LPDDR4 memory to deliver higher quality image signal processing (ISP) performance. This allows developers to quickly implement popular highspeed communication and display interfaces to accelerate embedded vision performance with classleading low power consumption for Edge applications including Machine Vision, Robotics, ADAS, Video Surveillance, and Drones.
Industry analyst Bob O’Donnell with TECHnalysis Research noted, “LPDDR4 memory provides device designers with a great range of dierent capacities/densities, speeds, and power requirements that can be matched to specific applications. Because of its low power nature, LPDDR4 memory is particularly wellsuited for embedded and machine vision in batterypowered devices or other applications where thermal management is a challenge.”
Highlights of the Lattice mVision solution stack version 2.1 include: Expanded support capabilities – the stack’s expanded capabilities include support for the LPDDR4 DRAM memory standard. With up to eight programmable SERDES lanes capable of speeds up to 10.3 Gbps, Lattice Nexus™ platform devices deliver the highest system bandwidth in their class to enable popular communication and display interfaces like 10 Gigabit Ethernet, PCI Express, SLVSEC, CoaXPress, and HBR3 DisplayPort (at up to 8.1 Gbps per lane).

smart factory technology ROLEC’s newly extended aluCASE and technoPLUS electronic enclosures are ideal for a wide range of IIoT and other industrial electronics applications in challenging indoor and outdoor environments. Both are rated IP 66 and IP 67 as standard (IP 69K optional).
Diecast aluminium aluCASE is a ‘go anywhere’ enclosure that can be mounted on machines, walls and bulkheads. It is available in 29 sizes.
Versatile technoPLUS features a unique polemounting attachment that enables the enclosures to be mounted either vertically or horizontally. The housings are moulded in five standard sizes from tough and UVresistant ASA Luran in light grey.
Both aluCASE and technoPLUS can be installed ‘lid closed’ to protect the seal and electronics. Both feature a large recessed lid for fitting a membrane keypad, front plate or product label. All ROLEC enclosures can be supplied fully customised.
