Yes, surgeries are pretty much entirely wired. Hospitals are conservative entities, and adopt new technology like wireless slowly and carefully -- intereference between devices can mean life or death. Video particularly is mostly copper based, since any loss of resolution (there's that word again) or time delay between a surgeon's movements and the picture on the monitor is unacceptable, both of which can occur with wireless video as it usually is implemented today.
Additionally, many (most?) video systems in ORs are on mobile carts, completely independent of any servers or permanently-installed monitors. A camera, light source, recorder/printer and monitor all reside together in a cart to be moved rapidly from OR to OR as needed. A single power cable is plugged in, and it's ready to use. A second, coax video, cable could extend to a built-in video system if wider viewing or monitoring is required. Very little compelling need for wireless links.
AJ2X - I'm not getting you wrong at all. I definitely get what you're saying. It's unfortunate that you've labeled my post a "shill comment". I prefer positive and respectful.
I stand by my comment that the article is a good one. What Charles wrote is sound. Many articles here are based on press releases. Each also gives a little more information to provide a bigger picture and encourage inquisitiveness. That's a good thing.
Agreed, that many articles here are indeed based on press releases, though I expect (I hope not unreasonably) those press releases to be at least looked at and vetted for technical rigor and not just passed along as fact.
Also agreed, that encouraging innovation and inquistiveness is a Good Thing. Having one's expectations raised by overenthusiastic and uncritical PR is, however, a waste of valuable engineering time.
We'll just have to disagree on whether this is "good article."
If you’re developing an embedded monitoring and control application, then you’ll want to take note of the upcoming Design News Continuing Education Center class, “Embedded Development Using Microchip Microcontrollers and the CCS C Compiler."
At the recent Consumer Electronics Show in Las Vegas, 3,600 exhibitors demoed new products, most of which used sensors. Accelerometers, magnetometers, gyroscopes, cameras, touch screens, infrared and radar sensors endowed products with the ability to see, hear, and feel.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
