Wearable Clip Helps the Blind Navigate with Ultrasound
From: Medical Design Technology - 10/29/2015

Canadian startup iMerciv Inc. has introduced the BuzzClip, a small, discreet,
wearable clip that identifies obstacles in the wearer's immediate
surroundings and notifies them by buzzing. As the user approaches an object,
BuzzClip sends out ultrasonic waves and vibrates to notify them, growing in
intensity and frequency as the user draws closer to the object. Three quick
vibrations warn wearers that they are about arm’s length from the object.
BuzzClip's range of detection isn't limited to large objects either -  it can
sense very small wires and tree branches as well.

BuzzClip's detection range can be toggled between one and two meter modes,
and the vibrator motor is enclosed in a sweat proof chamber - allowing for
both vibration isolation and a stronger response signal. It's easily clipped
onto virtually any piece of clothing, and multiple BuzzClips can be used at
once for more precise detection.
