Sensor networks are also increasingly being used for monitoring and controlling vital operations in industries, hospitals, and military installations and vehicles. Current research trends concentrate on Radio Frequency (RF) technology for sensor communications. However, OW communications or Visible Light Communications (VLC) can offer a much higher data rate or higher reuse factor. Comparison speed versus […]

DTMF encoding by GSM modem
It is not easy to detect and recognize DTMF with satisfactory precision. Often, dedicated integrated circuits are used. It is rather complicated, so it is used only marginally. Most often, a MT8870 or compatible circuit would be used. The MT8870 is a complete DTMF receiver integrating both the band split filter and digital decoder functions. […]

More Energy in Batteries. Nanowire anodes could let lithium-ion batteries run twice as long
More Energy in Batteries. Imagine the effect on GSM GPS tracking devices. A start-up based in Menlo Park, CA, plans to sell a new type of anode for lithium-ion batteries that, the company says, will let electric vehicles travel farther and mobile devices last longer without a recharge. Amprius‘ lithium-ion anodes are made of silicon […]
