[guide.chat] glasses to stop you bashing into trees, high cupboards

these glasses hav e been out a while now and for those who do not know our 
friend in canada sent me the following to put on the chat, when he is out 
walking with his guide dog in the park tree branches bash him in the face. now 
he wears these glasses that can be bought from r n i b, the glasses tell him 
when he is about to encounter a branch or tall cupboard, he says he turn them 
off when getting into a car, as the glasses think the door and roof and 
dashboard is an obstacle, they cost seventy nine pounds from r n i b and here 
is more about them. 

AMBUTECH 'Glasses Ultrasonic Mobility Aid

Important Safety Information

RNIB

The iGlasses are a secondary mobility device and must not be used on their own 
without another primary device such as a long cane, mobility cane, or guide 
dog. They are intended to warn you only of obstacles that may impact your head 
or upper body. They do not provide protection against, or warning of, any other 
obstacles or dangerous situations. The warning is in the form of a vibration 
from the frame of the iGlasses.

Turning the iGlasses On/Off

Press and hold for one second the round on/off button which is

located on the right-hand arm of the iGlasses.

You will hear beeps which indicate the level of battery charge:

? Four beeps: Fully charged

? Three beeps:        75% charged

? Two beeps: 50% charged

? One beep: 25% charged

? Ten beeps: Battery level too low for operation.

Charging required.

To turn the iGlasses off, press and hold down the on/off button for 
approximately one second. You will hear a single beep confirming they are now 
switched off.

iGlasses operation

The arms are adjustable and can be set to the most comfortable length by 
gently, but firmly, pulling the end of the arm away from the lens area.

When the iGlasses are on, the sending sensor will emit a continuous stream of 
ultrasonic signals. At the same time, the receiving sensor will detect the 
reflection of the ultrasonic signal and calculate the distance to the obstacle. 
  The two sensors
are located above the lenses on the front of the frame.

Obstacles that are more than 3 meters (10 feet) away will be ignored.   Any 
object within 3 meters will trigger a vibration in the iGlasses.   The 
frequency of the vibration pulse will gradually increase as the object gets 
closer until at a distance of
0.7 meters, (2 feet) the vibration becomes continuous. The ultrasonic signals 
are emitted from the iGlasses in an overlapping cone shaped pattern to maximize 
object detection.

Fine tuning the iGlasses

The iGlasses are delivered to you with the vibration level tuned to the lowest 
intensity.   The intensity level can be adjusted to your preferred setting by 
rotating the thumbwheel on the underside of the right side of the frame.   Turn 
the wheel towards the lens to increase the intensity.   Away from the lens 
decreases the intensity.

Charging the iGlasses

To recharge the battery, plug the provided charger into the small round hole 
between the intensity thumbwheel and the lens, on the underside of the right 
hand side of the frame. The built-in battery is a 3.7V 600mAh rechargeable 
Li-ion.

The iGlasses will beep for two seconds to indicate that the charge cycle has 
successfully started and will beep again for two seconds when the battery 
reaches full charge.   The charger will automatically deactivate when the 
battery is fully charged.

A full charge will take 2.5 hours (maximum). Only use with the power adapter 
supplied.
