What the heck is a Smart Grid?

Nowadays we have several issues to face that are causing concern to humanity in general and the western world specifically. I don't think I need to repeat them here but basically they are environmental as well as geopolitical in nature. Hence, the old coal or oil burning power plant needs to be phased out and we must become much more efficient at generating and delivering electricity to end users or the costs become extraordinary over time.

A "Cedia" Low-Voltage Initiative Proposal

Somewhere in the mid 1980's, the NAHB Research Center in Washington was run by a guy I knew (whose name I can't seem to dig up) who had a wacky vision. His idea was to reinvent the way electrical power was distributed throughout the home. They called it Smart Home (not to be confused with the Disney movie of the same name or other stuff that uses that name now). I think it was the first use of the name.

Adoption of Wireless and Powerline Controls

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.

Audio, Distortion and Feedback

Feedback is very large subject, and I am going to limit myself to some simple tutorial comments and a discussion of phenomena associated with complexity in distortion created by nonlinear gain stages, negative feedback, and the audio signal. Taken singly, these phenomena seem simple enough, but when they interact, they create distortions out of proportion to what you expect from the specifications found in product brochures. There are linear and non-linear forms of distortion. Linear distortions affect the amplitude and phase of audio signals, but don't show up on harmonic distortion analyzers as added frequency components that weren't there in the first place. Tone controls are a good example of circuits with linear distortion. Nonlinear distortions are those which add new frequency components to the original signal, either as harmonic multiples of the original frequencies or as sidebands resulting from their non-linear interaction between the original frequencies. Nonlinearities are often deliberately created in musical instruments themselves, but they are unwanted in music reproduction. We will be talking about nonlinear distortions.

CES 2009 - What is Hot

Every year for the last 20 years, I have been making the trek up to Las Vegas for the annual Consumer Electronics Show. Over the years, the show has evolved from a giant bazaar selling toys, watches and other household gizmos to the most important United States show for electronics, cameras, computers, gaming, audio accessories, etc. This year is no different. So far I have not seen any revolutionary announcements but several trends are definitely emerging.

CES Wrap-Up

We don't agree that this year's CES attendance was an indicator of an industry decline. The lower numbers were good for a lot of reasons. Unfortunately when the economic tide turns the hordes will probably be back. 3D movies/TV, mininotebooks and the constant din that we need our entertainment everywhere were the major news points for the show. Beyond that there were incremental enhancements/improvements. Paradigm shifts were not to be seen. But as CEA's Shapiro said it may be tough for a few quarters but the industry is going to innovate itself out of the global economic downturn. Flying to the seat of national government for handouts is not in the companies' DNA. Surviving and thriving in the PC/CE/content industry isn't always easy, sometimes not much fun but it is always interesting. This is one of those really, really interesting periods.

Next Generation Remote Controls

With a single, universal RF remote device, consumers will be able to control every aspect of their connected home. RF is engineered to control more than a TV and DVD, it can also control lighting, heating and air conditioning, blinds and shutters. Two-way communication can also be used to help you locate your lost remote control hidden in the couch pillows or under the table. This new generation of RF communication is opening up a market for low cost, reliable high speed RF remote controls and is expected to have a huge impact on the user experience, as IEEE 802.15.4 remote controls will allow a completely new way to use a remote control. In short, the development of radio frequency remote controls will replace IR remote controls and deliver richer communications, increase reliability and improve flexibility

Visions for 2009

Despite what a lot of "financial experts" say (weren't they the ones who got us into this position?) things aren't real bad -- yeah they're not real great either. But people in the business/consumer computer/entertainment/communications industry have never been short on optomism or ideas. Looking up from what is near the bottom of the valley it is fairly obvious that it will be a long, hard trek back up to the top of the hill. Some firms won't survive by this time next year. Those that focus on developing a strong consumer centric strategy and lead/listen to the marketplace will be light years ahead of the competition when we enter 2010. What's it going to take? What will the the leaders do? We've got a pretty good idea...hope you agree. We know most have what it takes to survive and prosper!

What Happened To The Smart Home?

Ten years ago, the "smart home" was all the rage. Almost every company in our market had a concept center or display house that showed the functionality of the digital home.

Brand Messaging: Manage your message or someone else will.

Ask any six people in your company the following question: What does our company do? If your employees don't answer consistently, your brand is likely weak and diluted. Identifying key messages and communicating those messages throughout the organization, and then externally, will improve the productivity of your communications and strengthen your brand. When the organization communicates with consistent messages and a unified voice, you will earn trust. Trust is the foundation of a strong brand.

Choice of Storage Media for Portable Multimedia Players

Unlike in the digital audio player market, the fight between NAND flash and hard-disk drive (HDD) on the PMP platform is far from over.

Classic Home Toys Installment #19 The Final CD Format: HDCD

HDCD is capable of higher quality sound reproduction because HDCD encodes the equivalent of 20 bits worth of data in a 16-bit digital audio signal by utilizing custom dithering, audio filters, and some reversible amplitude and gain encoding. Peak Extend, which is a reversible soft limiter and Low Level range Extend which is a reversible gain on low-level signals. There is thus a benefit at the expense of an increase in noise.

Content Insider #111 - Cloud Computing Netbooks, Cloud Computing - Work, Play Without Boundaries

Hammer Repair - Netbooks and cloud computing are great for certain times, certain activities and they will be used by lots of people - young and old - who just want to stay in touch. But when it comes to working with important information/material nothing beats a higher performance, higher capacity, heavier notebook.
