In this paper, we define the Inverse of a Finite State Transducer. The inverse and the corresponding Finite State Transducer are used for encryption and decryption of sequential data. The encryption process is designed for error detection capability during the decryption phase. Keywords-error detectiont capability;finite state transducer; Translational inverse;

As computers, sensors, and wireless communication have become smaller, cheaper, and more sophisticated, wireless transducer platforms have become a focus of research and commercial interest. This report describes an investigation into such platforms. It presents a new taxonomy of transducer systems, describes the construction of prototypes of a new transducer device designed for ease of applica...

OBJECTIVES To explore the use of a pyroelectric polymer (PEP) film as a transducer for a simple respiratory rate monitor and to evaluate the transducer in a laboratory situation. METHODS Laboratory evaluation of a new pyroelectric transducer for measurement of respiratory rate. RESULTS The amplified output from the pyroelectric film produced an excellent respiratory trace when used on a nor...

Intracranial pressure (ICP) is one of the most important parameters for evaluating intracranial conditons. The skulls of newborns and infants, unlike the tightly sutured skull of adults, provide non-invasive access for measurement of ICPs via the anterior fontanelle. A new transducer has been developed which is convenient for non-invasive, continuous measurement of intracranial pressure through...

A flexible system for determining the quality of agricultural products based on characteristics such as, for example, mass, shape, hardness, size, color and surface texture is disclosed herein. The quality determination apparatus includes a feeder assembly for sequentially dropping individual product samples upon an impact transducer arrangement. The impact transducer generates transducer signa...

Piezoelectric transducer (SAW devices) is a very important device in industry but it is very difficult to simulate it using any circuit-simulation program. This paper proposes a practical method to simulate the Mason’s model of piezoelectric transducer directly with no approximation for different values of the model’s components using PSPICE. The paper also improves the simulated circuit compon...
