This paper presents an approach to the detection of objects in a fixed frame. In this approach, an acoustic sensor is used for detecting any change in the surrounding of a fixed frame, i.e. detecting the entry of a foreign object. If it so happens, then the sensor sends a signal to the system which is processed. If the sampling result crosses the fixed(More)
This paper presents a Cellular Automata based scheme for generating Single Error Correcting, Double Error Detecting and All Uni Directional Codes (SEC-DED-AUED). In addition to (n,k) SEC-DED code an additional r number of check bits are appended which are responsible for detecting all unidirectional errors. The r-check bits are generated exploiting the(More)
