    The present paper proposes a method to implement a low-cost Localization System (LS) in a wireless sensor network (WSN) in open field. This method is based on RSS to obtain distance and angle values. Also this values are used to compute the position of the desired object, proposing the Localization by one Point (LboP) method. Although RSS values suffer alterations from different sources, in this p... View full abstract»

    In this paper, we present a low power wireless system based on a MSP430 based system-on-chip for biopotential signals acquisition. The system is capable of recording up to 12 ksps from up to 4 channels with independent gain and a 1 Hz to 5 kHz bandwidth. The gain for each channel may vary from 2.5 kV/V to 68 kV/V, being able to adapt signals in a range of 20 μV to 1 mV, to be digitalized in a 12 b... View full abstract»

    Every day we use location-dependant services, but there is still a lack of information in terms of a popular indoor location system. In this paper we show methods and some advantages of using already installed infraestructure such as WiFi Access Points to get navigation information. For these purpose an indoor navigation system was implemented using both inertial sensors and WiFi signal strength i... View full abstract»

    This paper focuses on the development of a time optimal control method for two-dimensional rigid body systems. Our approach is based on the traditional Proximate Time-Optimal Servomechanism (PTOS), which starts with a near-time-optimal controller and then switches to a linear controller at the time when the system output is close to a given target. This paper proposes to expand the PTOS, a unidire... View full abstract»

    The aim of this article is to introduce a protocol for embedded systems that delivers data between two nodes independently of the characteristics of the link. The development is platform independent and virtually portable to any communication standard. To demonstrate the performance of our protocol it was implemented in an ARM Cortex M3 LPC1769 microcontroller of NXP using first an UART serial pro... View full abstract»

    The present work describes the design, development and start-up of a portable wireless device for biopotential acquisition, the main strength of which is its versatility: full programmability of sampling frequency, bandwidth, gain, number of channels and topological setting. This enables the recording of different types of biopotentials such as electrocardiograms, electroencephalograms, electromyo... View full abstract»

    In this paper a hardware implementation of a Maximum Lyapunov Exponent (MLE) quantifier is designed and implemented using a field programmable gate array (FPGA). The design was optimized in terms of accuracy employing floating point architecture to represent the values. The proposed design takes advantage of the underline parallelism of the MLE computation equations and allows its concurrent imple... View full abstract»

    One of the most important aspects before installing a Wireless Sensor Network (WSN) is a previous study of connectivity constraints that exist in the area to be covered. This study is critical to the final distribution of the sensors, with an important impact in the life of the network by reducing consumption, and on the robustness by contemplating redundancy of paths and sensors. In this paper, w... View full abstract»
