Mike Brown for Inverse: The world’s first data transmission over a power grid has been successfully completed, paving the way for a decentralized future where smart houses tell each other how much energy they need. The tests, conducted by Reactive Technologies in the UK, sends data along the 50Hz electricity signal that passes through sub-station transformers that link up the country’s grid. The wires themselves have been used to send data before, but it’s getting through those transformers that’s never been done.
“We are keen to support innovative products like this one that can bring a real benefit for customers,” Cordi O’Hara, director of systems operator at National Grid, told The Guardian on Tuesday. “It represents another step forward in the development of the smart grid technologies that are going to play an increasingly important role in the energy systems of the future.” Cont'd...
One must consider all of these factors in determining whether electronic controls will replace electromechanical toggle switches. Wireless and powerline controls effectively address two factors in a positive way: absolute price and infrastructure. First, the cost of products based on these technologies is significantly less than traditional control systems installed by home systems integrators. Second, the infrastructure is already in place, so no new wires are needed.
With the truly robust 200-Mbps HomePlug AV standard-based PLC technology, home networks are established instantly with plug-and-play simplicity. It is the reason why service providers worldwide are having this proven technology embedded into their gateways, PVRs and set-top boxes.
Remember, any amateur home automation enthusiast can tell you if the garage door is "open or closed" based on magnetic contact sensors, but a REAL home automation enthusiast can tell you within a few inches the EXACT position of the garage door itself!!
The decision to use touchpanels should be based on the number of inputs and outputs (I/O) in the project. Projects that have a large number of lighting circuits, drapery motors, and whole house audio/video distribution with very little wall space for switches, definitely requires a touchpanel.
Yitran's PITEL mini-Access System is a low-cost robust networking solution designed for deployment in challenging environments. The system is ideal where traditional connectivity using hard-wired or wireless technology doesn't exist or is not economically or technically feasible.
A Transmitter unit is used at one location to impose a coded signal on the AC power wiring, and a Receiver unit (Receiver Module, Monitor Panel, or Display Panel) is used to receive, decode, provide control, and/or display this signal at other locations. In this system, no new wiring is required for signal transmission.
Fortunately, a repeater provides a practical solution for both of these problems in any X-10 compatible installation. In the X-10 standard command protocol, a controller sends the signal twice, back-to-back. The repeater listens to the first signal, then transmits on top of the second signal. It can boost a weak 25 mV signal to a 5V level that receivers can easily hear. The repeater also concurrently transmits on to the other pole in a home wiring system.
With powerline networking, you'll be able to put your desktop PCs anywhere you like instead of being forced to put them by a phone outlet. It will also be easier to buy and network other devices - printers, scanners, DSL and cable modems, TV set-top boxes, game consoles, screen phones and major appliances.
"When installing an automation or control system in your home that utilizes the powerline for communication, you should begin by educating yourself on what potential security risks there are and use sound judgment in determining how realistic the security breech scenarios are."
"Up to 190 X-10 events can be recorded and stored into non-volatile memory to be played back at a later date. The Analyzer stores the identity of the received X-10 code, it's signal strength and the elapsed time from the start of recording."
The ArtDiffusor® Model D (patent applied for) is the newest in the ArtDiffusor® Series. The Model D is an organic, quadratic diffuser; fusing diverse design concepts such as MLS, QRD, bicubic interpolation and boolean logic mapping. These rolling, asymmetric diffusers minimize specular acoustic reflections while improving sound clarity and ambience. Their design encourages developing customized patterns, allowing for a truly unique installation - every time.
