Facebook open source PCIe Timing Card combines atomic clock and off-air GPS reception

Facebook has open-sourced the precision PCIe timing card it created for its servers. It combines frequencies from a miniature atomic clock and GPS receiver, both on the card, with FPGA-based qualification that combines the two. The local clock is there for when satellite signals are not available, or are unreliable – for example during a ...

Ambient light sensor detects UVA for mobile sun exposure safety

Osram has created an ambient light sensor for mobiles and wearables that includes UV-A light detection. “While the UV-C portion of sunlight is blocked by the earth’s atmosphere, UV-A and UV-B radiation reaches the earth’s surface,” according to the company. “UV-B radiation penetrates only the upper layers of the skin and is responsible for sunburn. ...

6G: ETSI studies reconfigurable intelligent surfaces

Standards body ETSI is to create a specification for reflective RF ‘reconfigurable intelligent surfaces’ (RISs). “RIS is a new type of system node leveraging smart radio surfaces with thousands of small antennas or metamaterial elements to dynamically shape and control radio signals,” according to the organisation. The surfaces can be used to modify system coverage ...

Liquid level sensor works with simple electronics

Researchers at Yokohama National University have created a liquid-based tilt sensor that only needs simple interface electronics – some 10MΩ resistors and a Microchip ATmega microcontroller in the demonstrator. Although simple in theory – an air bubble and conductive liquid sealed in a chamber surrounded by electrodes – electronic levels are more complex in practice. ...
