Won’t Get Fooled Again . . .

No critique or judgement implied in the title of this post, just the lyrics of The Who’s song “…meet the new boss…same as the old boss…” percolated to the surface as I came across this press release last recently:

MTE Relaunches Prestigious TEAL® Brand for Precision Power (March 30, 2022)

Teal Electronics Corporation was my first and best client for many years. I worked closely with them developing and managing the PDU (Power Distribution Unit) for medical imaging systems with my then-employer Philips Medical Systems. I’ve consulted with them for ages – working on training, applications notes, customer support (remote and in the field).

I’m particularly fond of an Excel based viewer for their TEALwatch product – which you can see a bit of the GUI from here – Dedicated Line, Back to the Service Entrance

Times change, principals and technical contacts move on, we dropped the retainer in 2011, and my last invoice to them was 2015. They were purchased by MTE Corp in 2016, and despite a few fleeting contacts, my relationship with the company effectively ended. My guess is that the TEAL business unit itself got a bit lost in the shuffle.

They do seem to have tweaked the logo a bit. So that’s something . . .

I’m only slightly amused / disappointed that the sum total of the MTE / TEAL application library consists of 3 applications notes, the last survivors of a series I wrote for TEAL back in 1995….

Power Standards Lab: Announcing: The PQube 3 Family

Came over the email transom this week:

We are pleased to let you know that we announced the commercial availability of two new PQube® 3 models.The range of PQube 3 analyzers now includes:

PQube 3 – ultra-precisee multi-function and multiple-circuit power quality and energy meter. Ideal for immediate diagnosis of power issues, power consumption analysis, as well as environmental sensing, and external process monitoring
PQube 3e – multi-load powerr consumption monitoring for 14 single-phase loads, or 4 three-phase loads measured simultaneously; drastically lowering the per-circuit cost of monitoring
PQube 3v – voltage quallity analyzer; ideal for price-sensitive applications where compliance is required, while load monitoring is not

Features of the PQube 3 analyzers include:

Ultra-compact form factor; fits virtually anywhere – ideal for embedding (DIN-rail)
Detection and recording of high-frequency impulses at 4 MHz
Measurement of 2 kHz – 150 kHz emissions (first instrument on the market to cover the entire frequency range)
Four analog and multiple current channels (up to 14 on PQube 3e)

Benefits of using the PQube 3 analyzers include:

No learning curve – very intuitive, with no software needed
PQube 3 generates information you can immediately use – disturbance and trend graphs sent directly to your iinbox
Additional channels and embedded sensors provide a precise set of measurements covering the power side, plus process monitoring, and environmental parameters
Measurements can be used for verification requirements; PQube 3 is certified Class A IEC 61000-4-30 Ed3, and is ANSI Class 0.2/0.2S revenue-grade accurate
Optional enterprise software enables fleet maintenance and data aggregation

I’ve been a fan of PSL Founder Alex McEachern from back in the BMI days; have not had a lot of opportunity to work with the PSL devices / technology. To be honest, without an on-staff or on-call power guru (like me) to help sort out signal from noise, the technology seems a little hard to use / parse for the layperson. But cool as hell, from a power quality perspective….

RIP: MCM Electronics

From the ARRL Website (9/21/17):

MCM Electronics, in business for 40 years, will close two plants and its corporate headquarters in Ohio and lay off more than 90 workers, the Dayton Daily News reported earlier this summer. The company, which carries an electronics inventory of more than 300,000 items, including 3-D printers, tools, wire, cable, and other items, has been a Dayton Hamvention® vendor.

The layoffs will begin at month’s end and continue through the end of the year.

You can now find the MCM Electronics catalog on the Newark.com site:

MCM Electronics and Newark element14 have partnered together for over 32 years as part of the Premier Farnell family. Now, MCM will be strengthening this partnership under the Newark name. MCM’s unique product offering combined with Newark’s vast inventory, expanded services and global reach makes us the one stop shop for engineers, installers, educators and makers.

MCM Electronics and I go back a long ways. I’m pretty sure my first purchase was a set of Spin Tite nut drivers; I’d found them super handy in the labs at my first job at Superior Electric and soon after purchasing my first home I outfitted a workbench. Still have that small set of color-coded, english gauged drivers. Over the years I bought oddball tools and test equipment, parts and components, and most recently audio-video equipment. I’ve got a storage locker full of A/V gack: LED Par Lamps; speakers, speaker stands, lighting stands, lighting truss, XLR and speaker cables. Often purchased via one of the seemingly insane 50% off sales that would periodically flood my physical mailbox. MCM Electronics seemed to be one of the last bastions of physical catalogs; I still have their last catalog on my shelf.

Why yes, I did buy four of the 12″ PA speakers at $44.99 each…

It was never the highest quality stuff, but it was light duty, serviceable, good enough for my needs.And for whatever reason, their shipping department seemed to be amazingly responsive – I’d order stuff “slow boat” and it would show up 1-2 days later; big boxes of speakers or truss or whatever.

And while stuff still seems to be available, I have no doubt that the selection will narrow, the catalogs will stop coming, the to good to be true sales prices that often enticed me to buy will no longer be offered.

End of an era. There’s a lot of that going ’round in my world these days….

Philips Power Solutions

I was the national Power Quality Engineer at Philips’ North American HQ circa 1989-1995 and laid the groundwork for a lot of this. So this is interesting to see.

Overall, pretty well done. The “lousy power” waveforms are a little unrealistic / conceptual (I’d have insisted it was a little more realistic) but they hit all the high points. Think they futzed up the isolation transformer based UPS technology a bit (the isolation transformer is unique, but does not provide the conversion from AC-DC which is pretty standard in all online UPS systems). Interesting to see Rx Monitoring Services reports spotlighted; a good partner choice if one is using power protection as a revenue source.

I never got a kick ass video for my power program, if I recall correctly…

The Grid: The Fraying Wires Between Americans and Our Energy Future

Heard yesterday on Fresh Air: Aging And Unstable, The Nation’s Electrical Grid Is ‘The Weakest Link’

In her new book, The Grid, Gretchen Bakke argues that the under-funded power grid is incapable of taking the U.S. into a new energy future. She explains the challenges to Fresh Air‘s Dave Davies.

Just ordered a copy online; was a great interview and sounds like a wonderful book, dealing with the realities of balancing nearly unlimited, yet inconsistent renewable power sources (solar, wind, etc.) with the reality of consumer and commercial demand.

I confess to being a little curmudgeonly about issues of power usage, renewable energy sources, attempts to encourage consumer energy savings, etc. and this book gets to the heart of a lot of that. Really looking forward to this read!

OM Street 2016: Lessons Learned

Om Street 2016 has come and gone, and it was a big success on all counts. From the audio / tech perspective, lots of positive improvements from previous years, and thought it would be useful to document those.

Sound Systems: New for 2016, we were able to provide all of the sound reinforcement in house (yoga studio equipment and PowerLines equipment). While the equipment we’ve picked up is far from top-end or state of the art, it was solid and worked well. In previous years, rented or borrowed equipment introduced a bit of unknown that could complicate the set-up.

Speaker Cables: Picked up some additional lengths of speaker cables this year – 2 x 50′ and 2 x 15′ speakon-to-1/4″. This gave me plenty of length to push the speakers right to the curb – aesthetically better and safer.

Band Sunscreen: The band had asked to move across the street for shade. Not that practical (no super-long snake, no power on that side of the road, more narrow space with a sidewalk that can not be blocked) but I promised to set them up a sun-screen. I fab’d something from lighting truss and a couple of tapestries; one of our teachers is a set designer for Hartford Stage and buffed it up, and it was perfect.

Band Monitors: In previous years, the band set up a small PA and mixed themselves, and sent me a mix out to mains. Not a good plan. Then I took all the instrument feeds to mix and sent them a monitor feed for their little PA. Better, but lots of feedback potential (they tend to move the mics a lot and swap out instruments). This year, I dumped their PA (and insisted it not show up) and gave them a small headphone amp / distro with 4 separate outputs, and headphones for monitors. PERFECT. They got their sound without a lot of external interference, and I got zero band feedback.

Band Talkback: We’re a small event / location and do not own or rent PL headsets for communications. Instead, I set up two dedicated mics for the band and I which went ONLY to the monitors. With all of us on monitor headsets, it made it MUCH easier to set up the band mics and monitors, and then I simply pulled those mics out for the event.

We also streamed it via Facebook Live this year, so if you’d like to watch:

Meet the new boss…..

Siemens Healthcare Becomes Siemens Healthineers

We’ve been working with Siemens since 2001. Somewhere along May 2009, we transitioned reports and templates from being branded as Siemens Medical Solutions to Siemens Healthcare. So I suppose it’s about time for a bit of rebranding. Pretty minor change for us (the word “Healthcare” appears a grand total of 2x in the report templates we start from.

The new name embodies the company’s pioneering spirit and engineering expertise in the healthcare industry. It is unique and bold and gives a new identity to the organization and to the people – the people accompanying, serving and inspiring healthcare providers worldwide – the people behind outstanding products and solutions.

Makes me think of Walt Disney and the Imagineers (I’ve recently watched a PBS biography of Uncle Walt).
