Golden Mousetrap Awards: Electronics & Automotive Finalists!

Components, Hardware & Interconnects   Analog Devices Inc.'s AD9670 Octal Ultrasound Receiver   Analog Devices Inc. introduces the industry's first octal (eight-channel) ultrasound receiver with on-chip digital I/Q demodulation and decimation filtering. Because of the embedded demodulation and decimation feature, ADI's AD9670 is the first ultrasound receiver able to condition eight channels of data from RF to a baseband frequency, reducing the processing load on the system FPGA (field-programmable gate array) by at least 50 percent compared to other receivers. The AD9670 also integrates a low-noise amplifier, variable gain amplifier, anti-aliasing filter, and a 14-bit, A/D converter with the industry's highest sample rate (125 MSPS) and best SNR (signal-to-noise ratio) performance (75 dB) for enhanced ultrasound image quality. The new octal receiver is the latest addition to Analog Devices' award-winning ultrasound receiver portfolio and is designed for mid- to high-end portable and cart-based ultrasound systems.

Lift Buddy rocks

I like that Lift Buddy (slide 4)--we could use a modified version around here. I wish firewood hauling tool makers would integrate the lift function into their products. Aside from log bags, they make wheelbarrow-like devices something like this, but those are worthless on anything but flat surfaces, and tough to control even there. Incorporating this could at least help loading and unloading at both ends.

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.

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!

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!

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.

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...

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."

TI gas sensing platform
Charles Murray   1/29/2013 10:06:17 PM

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.

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.

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.
