Part 1 of this series, FMEA made automated and easy , demonstrated that physical prototyping alone is insufficient for determining all error conditions in the system. With capabilities for adaptable error modeling, and automated error insertion and analysis, Saber’s Testify tool enables a rigorous failure mode effects analysis (FMEA) methodology with significant time savings. Together, WCA and Testify form an effective robustness-validation solution for critical systems design.

It's natural for our audience to be interested in most popular” or top items”, and we happy to answer that interest. Below is a link to a spreadsheet, in pdf form, with 2010's most popular” items from Power Management Designline , measured by the basic metric of page views.

Please note that many of these items were first published (posted) prior to 2010, and that's OK. It shows that the issues and topics they cover are of lasting interest and value. For example, noise” is an issue that never goes away; it still with us as it has always been, and it also re-appears in different guises in newer applications, as well.

Take a look at the topics which the Power Management Designline audience—your fellow engineers and designers—were interested in. The list shows title, URL, and source (usually the vendor's name).

One other comment : an article I read several ago (I don't remember where) pointed out that mass-market magazines which are sold on newsstands find get better single-issue sales when they use prime or non-common numbers on their cover teasers: 13 ways to save money” or 37 ways to get a date” or 29 things ways to say 'it's over'”. Since we are online and we are not trying to sell magazines at the newsstand, won't use that gimmick—and anyway, this audience is too smart for fall for such a cheap trick. Our list presents the top 50 items, which seems like a reasonable cutoff number.

The ranked list does not include the number of page views per item. Sorry, that's confidential. But I can tell you that for this list, the top item (#1) received about ten times the page views of last item (#50). Also, there may be some minor rank-shifting, since 2010 has not yet ended, but I think any changes in that will be minor, if at all. Also keep in mind that items which were posted later in the year have had less of a chance to build up their numbers, compared to ones which were posted earlier in the year. Sometimes, life just isn't fair, as they say.

To see the list , click here . It is a pdf file, with live links in the column to the right of the articles, and the source to the right of the link column. Some of the longer article titles had to be truncated due to page-width limits, but you can still get a pretty good sense of the article's subject from what you will see. And even though the print is small, you can zoom it up, since it is a pdf file. [Final warning: depending on your set-up configuration, you may not be able to open the live links of the URLs; I am not sure why this is so. If this is the case, you'll have to cut-and-paste the URL into your browser.]

Enjoy!

About the author” Bill Schweber is the site editor of Power Management Designline as well as other sites under the UBM Electronics/EETimes umbrella.

Many of the most popular mobile devices have made the transition from being a predominately hardware based 'gadget' which provides a set of pre-defined tasks to an open ended platform for customizable software applications.

About the Author Alvin Cox serves as a Senior Staff Engineer at Seagate where his role includes overseeing PCB and flex layout; operational thermal analysis; component packaging; interconnections; and interface standards development. He serves as Chair of the JEDEC JC-64.8 SSD subcommittee and Task Group, Vice-chair of the SATA-IO CABCON Working Group, Chair of the T10 SAS PHY Working Group and editor of the T10 INCITS SAS 2.1 standard.   Mr. Cox joined Seagate in 1989 as a result of its acquisition of Imprimis Technology from Control Data Corporation. Prior to the acquisition, Mr. Cox was employed by MPI/CDC/Imprimis since 1980 as an engineer in mass storage product development.

A 48-year-old male patient with chronic obstructive pulmonary disease symptom (COPD) was discharged from the hospital with a telehealth system. During his recovery, this patient had daily video conferences with his nurse for four weeks. During each consultation the nurse collected his vital signs data, measured his lung function, and discussed how to prevent exacerbations. This practice of early assisted discharge and hospital at home is being experimented with by hospitals all over the world in order to improve patient care and reduce length of hospitalization.

Applications for home health technologies include chronic disease management, mental health services, post-operative care, independent senior living, weight loss, fitness, wellness and beyond. Home healthcare is currently booming because of factors such as ageing populations, increasing healthcare costs, and demand for access to healthcare resources in remote and rural areas. For many years to come, we will continue to observe an increase in medical electronics going into the home.

Medical electronics designed for a home environment versus a hospital setting have different requirements in terms of performance, feature sets, power consumption, portability, connectivity, and cost, which is covered in this article.

Size and Cost Consumer medical electronics being used at the patient’s home share some features common to other consumer electronics. Size and cost become more important factors in determining whether a product can succeed in the market. The first practical electrocardiogram (ECG) machine, invented by Willem Einthoven 100 years ago, weighed 600 lbs and required five people to operate it. The patient had to submerge his arms and legs into glass electrode jars containing large volumes of a sodium chloride solution.
