Signal to Noise

Sound pollution from roadways, outdoor gun ranges or shooting pits, industrial or commercial construction equipment, mining, manufacturing, you can wear hearing aids or wireless earbuds that can be configured with your smartphone app interface to these devices to have them provide active noise canceling. The technology leverages advances in computer science & information technology that affect nearly every domain of economic development worldwide, especially in emerging sectors or in emergent technologically advanced products & services. 

MEMS microphones & multiple sound input arrays from microphone clusters give digital devices spatial audio imaging that helps devices like the Amazon Echo lineup to engages users with a voice based interactive digital assistant NLP audio input output natural speech interface by leveraging elastic cloud computing on Amazon.com S3 service backbone infrastructure to do the heavy compute on clusters of servers such that your Echo Dot or similar end user device like a thin network client that uploads audio input voice queries when you say the wake word "Alexa" or "Hey Alexa" which then triggers a high resolution sound capture using a ring shaped array of microelectromechanical microphones to resolve your voice input with better signal to noise ratio so that the AI interface can make intelligible sense of your voice data while encoding it into compressed bit streams for rapid upload where the cloud computer decodes what was said into text using speech to text technology, then performs a internet query using the automatically generated text from voice input data, then downloads the search results into bit streams to the end user devices so that the DAC can convert the downloaded bitstream into analog articulation of the Dot's speaker or speakers depending on model. 

A sound amplifier circuit takes low intensity electrical signals from microphones for example and increases their power, in the dot this utilized to resolve distance voice inputs where the background noises in the room where the dot located may have similar signal intensity as the low volume voice search input request given to "Alexa" the personal digital assistant. 

Digital to Analog or DAC circuits and Analog to Digital or ADC circuits are embedded into an SOC or system on a chip package, typically an ARM architecture chip containing the CPU, Memory, networking & other aspects of the wireless WIFI Echo Dot node or thin client voice interface. Voice will continue to play an increasing role in terms of the way that people all around the world interact with computers & the internet, through Apple "Hey Siri" on iPhone & Apple Watch and "Hey Google" assistant functionality on android smartphones & smartwatches, from LG, Samsung, Kyocera, Huawei & other OEM's & ODM or digital consumer electronics manufacturing or design companies. 

Chipsets, like the SOC inside your smartphone or digital voice assist device like an Echo Dot or similar, leverage 3D stacking to put the RAM, CPU, GPU & other compute elements into a single chip package. This package also contain the transceiver modules for bluetooth & wifi & NFC or other similar, GPS, Galileo, or similar global navigation systems preset in COTS or consumer of the shelf electronics like a GARMIN navigation unit or similar. SOC chipsets are increasingly present in automobiles that have effectively become wireless data networking centers, especially those models equipped with autopilot or ADAS driver assist features like Collision Prevention or Lane Keep Assist, Automatic Emergency Braking & similar. 

5nm deep ultraviolet lithography on articulated first surface mirror equipment at the multi billion dollar scale are design & manufactured by ASML & utilized widely by TSMC to make the Apple M2 & other Apple Silicon SOC designs, like the one in our 2022 MacBook Pro, the M2 containing more than 20 billion transistors similar to 13th Generation Intel Chipset, with up to 40% better power efficiency, giving this little 3 lb MacBook that I am typing this on the ability to perform amazing computer rending 4K iMovie videos or browsing the web, with up to 20 hours of battery life. 

Power efficiency improvement or improving the amount of compute performed per watt of electrical power consumed a major & increasingly important topic because of E-commerce & cryptocurrency & video streaming platforms like Ebay, Bitcoin & YouTube respectively. 

You can answer phone calls on your wrist with Smart Watches, as fictionally portrayed in Dick Tracy movies from the 1990's, so that if someone calls my cell phone, a 2020 iPhone SE2, I can answer the calls on my Apple Watch SE, a smartwatch that can also function as a text messaging platform, fitness tracker, navigation haptics assistant when Apple Maps or Google Maps apps are streaming instructions from the respective smartphone, to help the driver navigate to a specific unfamiliar address with great precision on the first try. Navigation systems when used like this can reduce traffic congestion, vehicle emissions, improve transportation energy conservation even with electric vehicles, along with numerous other benefits like dynamic rerouting around unforeseeable emergent traffic accidents or sudden road closures along a route. Google Maps has real time traffic & other features and functions that are flat out astonishing to happen on a battery operating phone computer over 4G LTE or 5G NR wireless networks serving up bidirectional data wireless signal transceiver action with bitrate so fast it makes my contemporary digital HAM radio gear seem antiquated. 

We live in Amazing times if you stop & reflect on the state of technology in real world applications today, in middle 2022. Consider the rate at which COVID19 vaccines were developed & commercialized as historically unmatched or record breaking speed to market. 

Video streaming platforms like Apple TV, ROKU, Smart TV's, YouTube, Netflix, HULU & others, leveraging telecom information fiber optic networking infrastructure utilizing long life high quality infrared modulate diode lasers to pump high speed data and blistering fast bitrates for billions of people to connect online in increasingly interesting ways, to more products & services in more places, more of the time, helping globalization to develop in novel unique ways without a historical analog for meta analytical comparison. 

It will be really cool to look back at the life & times today, in 20 or 30 years, to perform long term meta analysis of emergent trending developments of all kinds, especially with energy & information technology. Your current smartphone will become technological obsolescent within 10 years. My bleeding edge M2 enhanced MacBook Pro really a smartphone with a large battery, more TDP, a cooling fan & heatsink to help keep the chips from overheating & a 10 finger physical keyboard typing interface & smart touch trackpad by Apple that enables multi-touch so fluid & dynamic that nothing else quite matches it, touch input precision excellence from a wonderful design from Cupertino California assembled in the PRC by Foxconn or Hon-Hai Precision, Pegatron, Samsung & others.

I recently took our DJI Mavic Mini 2 out of storage, charged the remote & drone battery & connected my iPhone as the display App interface to remote, then performed photography & video capture using the camera "panoramic" capture image stitching and Quick Shot "Rocket Mode video capture functions.
