    Estimation of objects in a 3D space is a fundamental problem in computer vision and robotics. This paper describes an algorithm and its implementation for a vision module as a sensor of a biped robot (YABIRO). The embedded vision sensor is able to estimate the position of objects like spheres in 3D space. Objects are defined with their size and color in a model. The vision sensor detects the posit...

    The present paper introduces a patient-friendly embedded electrographic (ECG) amplifier. In contrast to the standard ECG amplifier, the presented system uses only two electrodes to insure unobtrusiveness and compact design. The abandoned third reference electrode and required low power consumption introduce problems in ECG signal preamplification and handling. In order to meet them, a novel adapti...

    Critical embedded systems need a dependable operating system and application. Despite all efforts to prevent and remove faults in system development, residual software faults usually persist. Therefore, critical systems need some sort of fault tolerance to deal with these faults and also with hardware faults at operation time. This work proposes fault-tolerant support mechanisms for the BOSS embed... View full abstract»

    In this paper we introduce the development of a framework for testing safety-critical embedded systems based on the concepts of model-based testing. In model-based testing the test cases are derived from a model of the system under test. In our approach the model is an automaton model that is automatically extracted from the C-source code of the system under test. Beside random test data generatio... View full abstract»

    In this paper we work on the balance between hardware and software implementation of a machine learning algorithm, which belongs to the area of statistical learning theory. We use system-on-chip technology to demonstrate the potential usefulness of moving the critical sections of an algorithm into HW: the so-called hardware/software balance. Our experiments show that the approach can achieve speed... View full abstract»

    Sensor electronics is ubiquitous in embedded systems, yet its performance is susceptible to static and dynamic deviations. Even costly and time consuming laser trimming still can't deal with all the occurring deviations. Recently, analog reconfigurable electronics offers a solution to compensate these effects. The state of the art uses genetic algorithm (GA) to find an arbitrary topology to fulfil... View full abstract»

    In a previous work we have shown that by deploying a node with a high-quality oscillator (rate-master node) in each cluster of a real-time system, we can integrate internal and external clock synchronization by a combination of a distributed mechanism for clock state synchronization with a central mechanism for clock rate synchronization. By means of hardware and simulation experiments we have sho... View full abstract»

    This paper proposes a wireless sensor network based acoustics source localization and tracking system. Each individual node has a special purpose sensor board with four acoustic channels and a digital compass enabling direction of arrival (DOA) estimation of acoustic sources. Upon detecting a source of interest, the sparsely deployed sensor nodes report their DOA estimates to the base station that... View full abstract»

    A new acoustic localization scheme is proposed, which can be applied in sensor networks with low communication bandwidth. The first step of the two-stage algorithm is distributed and is evaluated at the sensors having possibly low communication capabilities. The sensors detect various events in the acoustic signal and transmit only the event descriptors to the base station where the sensor fusion ... View full abstract»

    A residential gateway can offer services that are configurable by a user depending on current needs or preferences. A set of these preferences can be grouped to form a user profile. One user may own several profiles depending on the environment (home or office) or time (working time or weekend). This article proposes smart cards for storing profiles and maintaining profiles in a secure and portabl... View full abstract»
