Researchers at Columbia University in New York have created an rf circulator that works at 25GHz. It uses a non-reciprocal structure – one whose physical characteristics differ depending on the direction of flow. In this case, it has a double ring where section of each ring are either directly-connected or cross-connected by switches. If the ...

Networking vehicles so that they can interact improves autonomous vehicle performance, according to Swiss university EPFL. Its researchers developed ‘co-operative perception algorithms’, which extend a vehicle’s situational awareness through data from a second car. “For example, in a scenario in which one car overtakes another car on a two-lane road, they developed an assistance system ...

Adafruit has created an ARM Cortex-M0 version of its Gemma wearable development board and single-board computer – the original has an 8bit ATtiny85. Called Gemma M0 it is 28mm in diameter and 7mm high, with crocodile clip sewing pads for solderless wearable applications and a Microchip (Atmel) ATSAMD21E18 on-board. This vastly more powerful chip offers ...
