The new architecture replaces star wiring with a serial bus. Smart speakers receive both data and power directly from the bus

Revolutionizing Car Audio Through Distributed E/E Architectures

My patent EP 4601324 A1 introduces a distributed electrical/electronic (E/E) architecture for car audio systems. Instead of relying on heavy centralized amplifiers and complex star-topology wiring harnesses, this approach integrates amplification directly into smart loudspeakers connected by a serial bus. The result is a system that is lighter, scalable, faster to develop, and perfectly aligned with the automotive industry’s shift toward zonal computing.

Temperature, altitude, and humidity directly affect air density and the speed of sound, altering how music is heard inside the cabin.

My patent US 2023/0199388 A1 focuses on real-time acoustic compensation in cars. By combining sensors and machine learning, the system dynamically adjusts audio output based on temperature, altitude, and humidity. The result: consistent, distortion-free sound in all conditions, preserving the brand’s acoustic signature.

It has been a very long journey for Cisium, Inc. website. It started in 2007 and this year finally I shut it down. I created the site using Joomla!, it overcome one major update in 2010. To use Joomla! as content management system has not been a pleasant job. In my experience Joomla! is slow and the administration is heavy. After many years using Joomla! in many websites, I don’t think it will use it anymore.

We are glad to announce that CISIUM website has been upgrade to the latest web technology.For this new version we have used the latest Joomla! 3.4. The release introduces new features into the CMS such as improved front end module editing, decoupling of weblinks, composer integration, Google new reCaptcha and security improvements by implementing UploadShield code which can detect most malicious uploads by examining their filenames and file contents.

Interesting project in Kick Starter about the biologic-electronics interaction. In this case a cockroach controlled with your iPhone. Well it is not so complicated, but it is very exciting. A simple PCB with Bluetooth LE (4.0 ready) module, I guess a TI CC2540, maybe from Bluegiga. Since it is BT LE, you can program any iOS device, and access to the hardware without paying the costly MFi homologation and authentication processor fees. BTW good news that Google stated that will support BT 4.0 natively, so soon available for Android I guess.

The Post-PC Era?

There are numerous news that I have been hearing that we are in the post-PC era, since Steve Jobs prophesied. Mmmmh ... well among some of my qualities I am dedicated to the complete design of electronic systems based on microcontrollers, in my case lately I am designing systems based on implementations of ARM cores by NXP. These processors are called SoC, System on Chip, which means they have a lot of integrated peripherals.

Obviously the heart of the system is the MCU/CPU. My approach was to find out a balance between the cheapest, most powerful, and higher trend MCU in the market. Without any doubt the winner is the AMR, many manufacturers have adopted these cores: TI, Samsung, nVidia, Intel, Atmel, NXP, Freescale, a never ending list. For a system designer like Cisium this provides a big advantage, this allows to switch between manufacturers with similar cores with a great reutilization of the knowhow.
