Panasonic and Matsushita Electric

The brand Panasonic was created by Matsushita in 1955 for the US, Canada and Mexico because the National brand was already registered by others The Panasonic brand was created from the elements “pan” meaning “all” combined with “sonic” meaning “sound”, because it was first used for audio equipment.

Matsushita Electric Industrial Co. – Panasonic – Wikipedia

It was founded by Konosuke Matsushita in 1918, with its first product being a duplex lamp socket. In 1927, it produced a bicycle lamp, the first product it marketed under the brand name National.

Not only does the KX-MB2061 include standard printing, color scanning, copying, and fax capabilities; it also includes a built-in digital answering system and DECT 6.0 cordless telephone system with corded handset, which is expandable up to 6 handsets.

IEEE Microwave Theory and Techniques Society

“The IEEE Microwave Theory and Techniques Society – MTT-S is a transnational society with more than 9,000 members and 80 chapters worldwide. Our society promotes the advancement of microwave theory and its applications, including RF, microwave, millimeter-wave, and terahertz technologies.”

“The activities sponsored by the MTT-S include a broad spectrum of conferences, workshops, tutorials, technical committees, chapter meetings, publications and professional education programs.”

IEEE Microwave Theory and Techniques Society

IEEE – The IEEE, a non-profit organization, is the world’s leading professional association for the advancement of technology.

The MTT-S’ field of interest is “microwave theory, techniques and applications” of RF, microwave, guided wave, and wireless technologies, as they relate to components, devices, circuits, transmission lines, and systems involving the generation, modulation, demodulation, control, transmission, detection and effects of electromagnetic signals. It shall include scientific, technical, and industrial activities.

National Electronics Museum

From telegraph and radio to radar and satellites, the National Electronics Museum offers visitors access to the electronic marvels that have helped to shape our country and our world.

Multi Zone Process Controller

This was one unique custom design i made for a Mining Company for Ore Processing. It was Multi Zone Scanner controller.

Multi Zone Temperature Controller

It might have been for a rotary kiln of a large size. Four temperature sensors were connected to the system with brushes just like in a motor. Even the supply to the trasmitters was on the brushes.

The Instrument had a Analog Multiplexer with a Synchronous Sample and hold, as the analog value was coming via the brushes. It had four relays that would turn off or on every scan cycle, depending on the input values. The kiln system was slow it had inertia, so it did not require a fast acquisition for ‘Real time’ as you may find necessary in small Thermal Systems.

This was built with analog and digital chips, no uC in this design. This was because it was a front end controller, there was a risk of a uC system getting stuck. These days, that problem may not be so worrisome, but i am not so sure.

What if the watchdog goes for a short nap?
