Dark lattice modes used to create laser light

A plasmonic nanolaser that operates at visible light frequencies and uses dark lattice modes has been made by researchers at Aalto University, Finland. The results are said to open new prospects for on chip coherent light sources.

Optical fibre sensor enables real time detection

Optical fibre sensing shows promise for monitoring the condition of structures. By embedding long optical fibres into a structure, strain and temperature distributions along the fibres can be detected. Until now, however, time of distributed measurement took from several tens of seconds to several minutes.

Visible light communication now possible in the dark

A Dartmouth project called ‘DarkLight’ is said to have demonstrated for the first time how visible light can be used to transmit data even when the light appears dark or off. DarkLight is claimed to provide a new communication primitive similar to infrared communication but it exploits the LED lights already installed rather than needing additional infrared emitters.

Top five Raspberry Pi 3 project ideas

The Raspberry Pi 3 Model B is said to deliver up to ten times the processing performance of the original Raspberry Pi and includes connectivity with 802.11 b/g/n Wireless LAN and Bluetooth 4.1. The board is claimed to be suitable for IoT-based projects, as well as application in security, home automation and machine vision.

Metering Solutions for the Smart Grid

For AMR (Automtated Meter Reading) and AMI (Advanced Meter Infrastructure) to become truly pervasive it needs to provide more than a reduction in meter reading costs. Optimisation for Asset tracking, dynamic pricing, tamper notification, outage management, supply automation, load profiling and network diagnostics are critical elements for the success of this infrastructure. The trend towards AMR increases the electronics content of the meter itself, and AMI drives a networked infrastructure for all metering. TI's comprehensive utility metering portfolio includes devices targeted at electricity, water and gas metering, as well as power line communications (PLC) and radio frequency (RF) interfaces for AMI that allow customers to design smart grid solutions. From highly optimized application specific embedded processors, low-power RF, power management and RFID to dedicated software support for ZigBee, WMBUS, OFDM and SFSK modulations, TI offers the most complete solution set for smart metering. This presentation discusses the fundamentals of e-metering and various solutions for both the metrology and communications aspects of e-metering.

Freescale - The era of connected intelligence/networking

Today's high speed society expects communications devices to connect quickly and intelligently. The demand for 'wireless everywhere' is accelerating - leading to substantial changes in the infrastructure, including deployment of a range of small cell to large cell base stations.
