Golden Mousetrap Awards: Electronics & Automotive Finalists!

Analog/Power Management/Control   Microsemi Corp.'s Radiation Hardened Isolated DC/DC Converters (SA50-28)   The SA50-28 is a family of radiation-hardened, surface mount technology packaged 28V input, 50W output DC-DC converters. Naturally occurring radiation in the environment can have a catastrophic impact on electronics used in military/commercial satellites. The high-reliability SA50-28 single, dual, and triple output converters continuously protect against this 'total dose' ionized radiation. The space-qualified SA50-28 series was developed in response to customer requests for a high reliability alternative to hybrid solutions, and less robust competitive products that were causing design issues and schedule delays. This product series delivers simple and standardized SMT construction that aligns with typical satellite load requirements while providing significantly less risk than competing products. In addition to improving quality by leveraging automated and repeatable surface mount technology processes, the SA50-28 series allows designers to maximize board real estate resulting in a similar package and weight density to hybrid alternatives. The DC-DC converters feature a fully isolated power supply capable of driving high-reliability point-of-load converters used to 'step down' power to devices such as customizable system-on-chip solutions and FPGAs. Additional features include a fully isolated synchronization scheme to manage system noise spectra.

Good point. However when I sared with computers, I was able to loan one home for a weekend. It was doind 6 operations and he weight was about 18kg.

This was a workout and not only for my brain.

I would like to know how high the Lift Buddy can lift. Most of the toughest tasks (for example, in my garage) require a reach of about eight feet. If the Lift Buddy can do that, they've got a customer.

Nancy, that sounds like an other great app for Lift Buddy. It's been several years since I had to lift a saddle, but I'd probably have problems now getting one onto a horse's back.

TI gas sensing platform

TI's gas sensing platform is another interesting one. Gas sensing systems are a growing market for the home. Emission testing stations can also use them for measuring exhaust gases. On the inside of the vehicle, there could also be a growing market in alcohol (breathalyzer) sensing, as well as carbon monoxide sensing. I've always wondered when someone would develop a CO sensor for inside the car. Anyone who's ever driven an old beater knows the importance of that.

When it comes to technology, most pronosticators have been notoriously inaccurate. Here's one of my favorites from Popular Science in 1949: "In the future, computers may weigh no more than 1.5 tons."

Reminds me of a funny story, Charles. When I was a kid, I interviewed my neighbor who happened to be an engineer for Texas Instruments for a school assignment. He told me that when the transistor first came out - they said it was just a fad...

Over the years, we've heard many prognosticators predict the demise of 8-bit, Nancy. The folks at Microchip always laugh about it. Seems like they've always had the last laugh.

I agree Charles - love 8 bit microcontrollers and leave it to Microchip to expand on its peripheral capabilities. Seems like there is a PIC for every task!

I agree Ann - after reading your post, I could hardly wait to see the Lift Buddy. I have had a similar prototype in the works for years that we call the "Saddle-Jack." Being a horsewoman, I have seen a need for something that would help folks who are prone to back problems to be able to saddle their horses by themselves. We have the two wheeler but are still in the brainstorming stage for making it work in a cost-effective manner. That Lift Buddy is a great idea for lots of applications!

It's amazing to see how many peripherals Microchip is able to integrate onto an 8-bit chip. I suppose that's why, after numerous predictions of ther demise of 8-bit, it's still going strong.
