This paper compares the fieldbus protocols LIN 1.3, LIN 2.07 and TTP/A to the requirements of low-cost body electronic networks in the automotive domain. The examined protocols all aim at distributed smart sensor/actuator networks and provide support for low-cost implementation on standard microcontroller nodes. LIN comes with a rigid specification of the physical layer in order to support interoperability...
In this paper we show some sensor linearizing methods based on feed-forward neural networks (multilayer perceptron). These procedures can be easily programmed into a computer-based data acquisition system. Nevertheless, we show that introducing some simplifications in the neural network architecture, these linearization procedures can also be programmed onto low-cost microcontrollers for embedded...
The paper introduces a new event-based criterion for discrete representations of continuous-time signals, which can be used in intelligent sensors to report the current state of the observed object. The criterion is based on the control of the sampling error energy. The analytic approximation of the mean sampling rate for a given sampling resolution is derived. The formula for the reduction of sampling...
Time-triggered systems are advantageous for embedded applications, when determinism, hard real-time behavior, and a straightforward way for certification are required. However, when it comes to flexibility, time-triggered systems often require that possible extensions have been planned in advance, which makes it difficult to apply unforeseen changes to such a system. This paper presents an approach...
Measurements of human physiological data allow inferring information on the mental and emotional state of a human. An increasing number of application developers and scientists of different domains want to make use of this additional information on users. To be accepted in practical application, systems of this sort have to be easy to use, should not intrude the user by wires, and it should be easy...
