Wireless Charging

Background Information:

Wireless charging isn't necessarily a new concept, but within the past few years, it's application has become more and more practical. Wireless charging is used to charge many newer phone models and eliminates the need for cables, while also providing a source of efficiency and easier accessibility. 

Besides from charging your phone, wireless charging is used for many other purposes in healthcare, automotive and manufacturing industries. Wireless charging offers increased mobility in these industries and could provide advances allowing IoT devices to receive power from across the room.


How It Works:

Wireless charging functions by transferring energy produced by the charger to a receiver on the back of a phone through electromagnetic induction. The charger creates this energy with an induction coil that produces an alternating electromagnetic field. The receiver in the back of a phone converts the energy in the electromagnetic field of the charger into electricity and feeds it into the battery of the phone.  

The current form of wireless chargers requires that the phone be within close proximity and correctly aligned upon the charger for the transfer of energy to take place. The bigger the coil, or the more coils there are in the charger, the greater the distance the charge can travel. 


Impact & Future Growth: 

Wireless charging has transformed the technology industry and has demonstrated the advancement of technology and the potential for technology in the future. Wireless charging is becoming more and more popular with many new phones including the feature and promoting the use of wireless chargers. It is very likely we will continue to see improvements and breakthroughs in the wireless charging market for the next few decades!

Advantages:
  1. Convenience - eliminates the need for frustrating and messy cords.
  2. Compatibility - most wireless chargers work with all cell phones, no matter shape or size, as long as they support the wireless charging feature.
  3. Numerous wireless chargers support the charging of multiple devices at once.
Disadvantages:
  1. Wireless chargers tend to lack efficiency and can simply not charge as fast as traditional chargers. 
  2. Mobility - most wireless chargers require that your phone sits upon them, which prohibits you from using your phone while it is charging.

Noise Cancelling Headphones

Image
Background Information: That annoying buzzing noise you hear on planes, trains, and in cars can really ruin your music listening experience. Everyone owns a pair of headphones or earbuds, but wouldn't it be great to reduce that background noise so you can enjoy your music without distraction?  Noise cancelling headphones and earbuds are a hot commodity in today's technology market, and the noise cancelling technology continues to gets better and better.  How it Works: A microphone located on the outside of the headphones or earbuds listens to the ambient noise around you. Circuitry within the headphones creates a replica of the detected sound wave and resends the wave out of the headphones. This process limits a majority of ambient sound from entering the earbuds. Some sounds are completely cancelled by the circutry, but most noises like people talking, car radios, and keyboard typing are only reduced in loudness.  Impact & Future Growth:

Deepfake Artificial Intelligence

Image
Background History:  There have been many breakthroughs in artificial intelligence over the past few years. Although the use of artificial intelligence is supposed to be beneficial to humanity, developments like Deepfake AI are proving the malicious potential of artificial intelligence.  The term deepfake refers to forged, computer-generated video and audio that is difficult to discern from authentic, unchanged content. Deepfake AI is essentially the equivalent of Photoshop, but for video. Deepfake has been utilized to reproduce unsettling audios of presidential voices and to completely delete objects once present in video.  How It Works: Deepfake depends on the the use of generative adversarial networks (GANs), which includes two subset artificial intelligence systems. One system generates content and the other guesses or determines whether images are real or counterfeit. The two AI adversaries progressively get better and better at their function over time, and event
