Abstract

This project aims to develop and manufacture new passive movement detection sensors. In the world market, many of these sensors do not operate in a robust manner in the detection of standards of variable sizes, as, for example, the silhouette of a human body or of small to medium size animals. Sensors on the market today carry out this task (pet immunity) only very approximately, or merely so as to minimize the problem in situations in which different body masses generate similar signals. To get round this problem, a new hybrid concept called wave front coding is used. This combines optics and electronics aiming for an improvement in the system’s performance and reducing the final cost of the product. In phase 1 of this project the bench top prototypes for the presence detectors should be assembled, to show the technical and economic viability of the idea. In phase 2, the sensor will be encapsulated with the technologies developed in the first stage, bearing in mind the assembly line processes already existing in the company.At the end of the project, the intention is to have mass production of the sensor and to launch it on the market by means of an appropriate marketing strategy. Even with the inevitable increase in its price, it is believed that the innovative imbedded technology will be quite superior, so that the product will still remain competitive. (AU)
