Bat Sonar

Intro:

Now the new vampire is not what you are thinking, but a new technology by K-Sonar [3] has created a cane that can help guide blind individuals. The cane uses the method of echolocation by emitting a hypersonic sound and receiving echoes to determine an object’s whereabouts. Much like the bat in a cave, a blind individual can only see pure darkness, but with this new cane to help navigate in the everyday, they can now see the light.

UltraCane:

The cane works as explained above by using echolocation and conveys these received signals into vibrational signals that are carried through the Animated Sonar Canehandle of the cane to the operator’s hand. The cane sends out a high-frequency sound that bounces off of nearby objects at a rate of 60,000 pulses per second [4]. Figure 2 shows an animated picture that describes the shape and basis behind the cane. Video 1 shows the theory behind and actual functioning of the sonar cane.

Now this item is not cheap, at least not yet, but spending a mere $635 [4] to be safe in every area of your world is definitely worth the cost. One of the best features that the cane offers is that the echolocation works in three dimensions. So if there is any obstacle within three meters of the operator’s hand, they are able to avoid it without worrying about the corner of the table creeping up on them. The application of this sonar technology is very prevalent in the cane apparatus, but what else can it do? A scientist in the UK has taken sonar directioning to the next level. Watch Video 2 to really grasp the immense positive interaction the sonar technology has with vision impaired people.

    This is really cool and interesting, I love seeing innovation that can help those with disabilities adapt to their environment. One question I have is what powers the device (I assume a pretty large power source due to the high frequency).

      They never really mention the power source, that was one of my questions as well.
