Abstract-The stereausis model of biological auditory processing was proposed as a representation that encodes both binaural and spectral information in a unified framework. We describe a working analog VLSI chip that implements this model of early auditory processing in the brain. The chip is a 100 000-transistor integrated circuit that computes the stereausis representation in real time, using continuous-time analog processing. The chip receives two audio inputs, representing sound entering the two ears, computes the stereausis representation, and generates output signals that can directly drive a color CRT display.

This paper describes a sensor interface for metal-oxide chemical gas sensor for pollution detection. The function of the ASIC is to control the sensor working temperature by applying a programmable voltage with 10 bits resolution, to measure the resistance of the sensitive elements ranging from 5KQ to 100MS1, measure the ambient temperature with an external NTC thermistor and offer a fully digital user interface. It gives the possibility to make low power and low cost high performance gas sensing micrsosystems for consumer application.

IntroductionSociety, education and the university need to reconsider their relationships at each historical moment based on the priorities or codes of behavior that are deemed appropriate by the entities, governments, businesses or advocacy-groups that can take decisions according to the available resources and in order to answer to the needs or demands of the population, in general, and of the organizations, professional, workers, researchers, students, specifically. If we accept this argument, then we accept the premise that society is in constant transformation (Toffler, 1980) ABSTRACTRelations between Society and Education are being reconsidered at each significant point in time based on the current situation and facts. Taking into account the possibilities and limitations of the economic, social and cultural climates, it is therefore necessary to make continuous adjustments depending on the actual stage of development of the concurrent ecosystems, considering also their integrating elements, in order to synchronize the development of shared projects in the short, medium and long term in all environments: political, business, academic and social, In this framework, we have been progressing in recent years, in both theory and practice, in the construction, the development and the implementation of an inclusive ecosystem model that integrates training, research and innovation of professionals and users to provide comprehensive answers to the needs and demands of involved organizations, institutions, as well as of the citizens in general. The ecosystem model serves as a platform to manage knowledge and a network of institutions. In this article we present some of the projects that we are supporting from the Institute of Research and Educational Innovation (INIE) of the University of Oviedo, as well as the difficulties we are encountering, the progress and future challenges.Keywords: ecosystem of training, social inclusion, didactic methodology, collaborative learning, knowledge management, teaching practice, combined teaching.Modelo ecosistémico inclusivo para la gestión del conocimiento, la formación y la innovación: avances, dificultades y retos RESUMEN Las relaciones entre Sociedad y Educación se van reinterpretando en cada momento histórico concreto en base a circunstancias situacionales. Ante esta realidad se hace necesario realizar ajustes continuados en función del estadio de desarrollo en que se encuentren los ecosistemas concurrentes, así como elementos que los integran para sincronizar el desarrollo de proyectos compartidos a corto, medio y largo plazo en los ámbitos políticos, empresariales, académicos y sociales atendiendo a las posibilidades y límites coyunturales, situacionales y culturales. En este escenario venimos avanzando en los últimos años, desde la teoría y la práctica, en la construcción, desarrollo e implementación de un modelo ecosistémico inclusivo que integra la formación, la investigación y la innovación desde el que gestionamos el conocimiento y las redes de instituciones, de profe...
