A system for enabling blind people to identify landmarks: the sound buoy

, : A system for enabling blind people to identify landmarks: the sound buoy. IEEE Transactions on Rehabilitation Engineering 5(3): 276-278

This paper describes a set of low-cost sound beacons. The paper introduces the problem area that motivated the work, considers alternative solutions and describes the radio triggered solution adopted. The paper discusses further developments to make the system suitable for indoor as well as external use.

Thromboxane (TX) is a vasoactive hormone which is known to be involved in renal physiology and pathophysiology. To identify the site of action of TX in the kidney, we examined the distribution of this receptor in the normal rat kidney using a poly...
