TheraProx: Capacitive Proximity Sensing [PDF]
This paper presents the development of a novel contactless omnidirectional capacitive proximity sensor. The presented device has been designed to be energy-efficient (≈5 mW power consumption) by means of duty-cycling the power supply. A comprehensive methodological experiment has been carried out to extensively evaluate the performance within the ...

IN NATURE for March 11 there is an interesting account by Dr. McKendrick of some investigations by Kunz, of Mulhausen, and Prof. Griesbach, on the senses of the blind. Among other points that he refers to and discusses is the question of the ability of the blind to avoid obstacles and find their way about.

Proximity sensing with wavelet-generated video [PDF]
Abstract : In this paper we introduce wavelet video processing of proximity sensor signals. Proximity sensing is required for a wide range of military and commercial applications, including weapon fuzing, robotics, and automotive collision avoidance.
