What Smart Lightbulbs Do Best: Hide Your Other, Uglier Gadgets – Businessweek

The Good Business Issue

A Sony representative couldnt say when the lamps would go on sale or whether they would look anything like the items on display.Thecompany does plan to begin selling amusical bulb thatcan be screwed into a normal lamp at some point this year, but itcouldnt say how much the bulbwould cost. Sengled, a Chinese lighting company, is also showing off several bulbs that do more than light upa room. The companys Boost bulb, which will cost $50, doubles as a Wi-Fi extender, increasing the power of a Wi-Fi signal in areas of the house that might not be served well by the primary router. (It already sells lightbulbs with speakers in them, for $170.) The company is also displayinga suite of products called Snap, bulbs with a built-in security camera, microphone, and speaker, as well as motion detectors and facial recognition, that can be installed inside or out. Taken together, these souped-up lightbulbs start to answer the question that has dogged the makers of previous iterationsof smart lights.

Avago Demonstrates Industry-Leading 56Gbps PAM4 SerDes – Yahoo Finance

Once they’ve established contact with a device, they send out focused RF signals on the same bands as WiFi that are then absorbed and converted into DC power by a tiny chip embedded in the device. These transmitters can be built into household appliances, TVs, speakers and standalone “energy routers.” This conversion, known as “rectification,” is not a new idea, but Energous’ application of it is. Its latest generation of chips are around 70 percent efficient — a typical wireless charging mat clocks in at around 90 percent — and can provide enough power to easily charge both a phone and wearable from a single bedside transmitter. To demo its tech, Energous has turned a casino suite into a faux home full of wireless power, which we dropped by to allow the company’s founder Michael Leabman to put on a show for us. The routers are able to offer a closed network, letting you choose what devices are allowed power (ideal for public locations), or an open network, offering power to all. Regardless of network type, the router can prioritize devices low on battery, and automatically rejig the hierarchy as a desired charge level is achieved.
