Displays are becoming increasingly important as an interface between man and machine. Displays are constantly in use both to display personal performance values, for queries in the consumer, medical and POS sector and as simple status indicators in smart homes and with smart metering or, alternatively, for measurements, control and optimization values in the industrial and automotive sectors.
In mid-July, the Bluetooth Special Interest Group published instructions for eliminating security vulnerabilities in the “Secure Simple Pairing” and “LE Secure Connections” processes. Rutronik now offers a manufacturer-independent overview at rutronik-tec.com/bluetooth-security-vulnerability-status/, which shows the patch status of the individual chip and module manufacturers. The site is kept up to...
Industrial Ethernet enables continuous communication between actuators and sensors at field level and management systems. It also combines real-time capability with the robustness and security of fieldbus systems – which is why it is gradually replacing it. For Industrial Ethernet to also satisfy tough real-time requirements, crystals and oscillators of high signal precision and reliability are needed.
The use of shunts for measuring current is a simpler and more cost-effective alternative to the use of sensors for current measurement. However, they are precision measuring devices, and a few things need to be considered to achieve measurements of the necessary precision.
Without sensors, there can be no Internet of Things (IoT). The fact that they require power is often overlooked. Not much, mind you – but they cannot work without it. The latest switching regulators allow sensors to be powered for much longer using batteries. Even from a 4–20mA current loop, it is possible to produce three times as much power.
