Invención e innovación tecnológica en el ciclismo en España a través de la documentación de patentes : 1826-1929

El objetivo general de esta investigación consiste en sacar a la luz un conjunto de documentos, los documentos de patentes presentadas en España, sobre un tema concreto, la bicicleta y el ciclismo, y durante un periodo determinado, 1826-1929, presentes en la Oficina Española de Patentes y Marcas (OEPM), organizando esta documentación para su posterior utilización por la comunidad científica. Para ello se han identificado y sistematizado las patentes referidas a la bicicleta, presentadas entre 1826 y 1929, realizando tablas de frecuencia que permitan extraer datos de su incidencia en la invención en el periodo considerado. Ello ha permitido conocer una serie de datos de los inventores, que, en definitiva son los creadores del desarrollo tecnológico en este campo, extrayendo, ordenando y categorizando la información sobre lugar de origen, tipo de inventor (empresa o particular), sexo, práctica de colaboración y profesión. Finalmente se ha estudiado el tipo de inventos, mostrando los sectores en los que se producen las invenciones, identificando si se han puesto en práctica, y determinando aspectos tales como su carácter de invención incremental, su posible consideración como invento raro y curioso, y su coexistencia con una marca registrada. El trabajo se inicia con la introducción seguida de un apartado en el que se presenta el marco teórico en el que se desarrolla la investigación, en una doble vía: en primer lugar el contexto de los documentos de patente, su relación con la innovación y su utilidad como fuentes de información, y en segundo lugar el marco de la invención en el ciclismo, presentando las fases esenciales de la evolución de la bicicleta (capítulo 2). En el marco metodológico (capítulo 3) se explican fuentes y metodología, presentando a continuación el diseño de la investigación, que se resume como sigue: 1- Determinación del universo de datos, 2- Consulta en el Archivo Histórico de la OEPM, 3- Diseño y creación de la base de datos propia, 4- Consulta de los expedientes y toma de imágenes, 5- Tratamiento y análisis de los datos, 6- Búsqueda de información en fuentes para patentes extranjeras, y 7- Consulta a la base de datos de Marcas de la OEPM. El capítulo 4 está dedicado a la investigación propiamente dicha, estructurado en tres grandes bloques. El primero recoge las cuantificaciones tabuladas del total de patentes y el análisis de determinados aspectos generales como la cronología de la invención y diversas comparaciones con resultados obtenidos en otros trabajos. El segundo bloque está centrado en los estudios de solicitantes de patentes, protagonistas de las invenciones. De ellos se contemplan una serie de datos extraídos de los expedientes, y posteriormente tabulados y cuantificados: su procedencia geográfica, su adscripción como empresas o solicitantes particulares, y sus datos de colaboración, finalizando el bloque con un apartado que dedicamos a la innovación femenina, que consideramos una línea de investigación interés. El tercer bloque, el más amplio de todos, está dedicado a la descripción y análisis de los datos referidos a los propios inventos, puesto que es la aplicación de los inventos lo que marca el desarrollo tecnológico de la máquina bicicleta, y su consiguiente evolución histórica y social. Se estructura asimismo en varias secciones. La primera es la más amplia, donde se muestran y explican los datos que tienen que ver con la adscripción de los inventos a sectores temáticos, es decir, que desarrolla las funciones o componentes de la bicicleta que han sido objeto de invención. Los apartados siguientes muestran datos y consideraciones sobre las patentes puestas en práctica, las invenciones incrementales, los inventos curiosos, y las patentes con posible marca registrada de su nombre. Finalmente, las conclusiones del estudio, el establecimiento de posibles líneas abiertas de investigación, la relación de fuentes consultadas y los anexos cerrarán la exposición de esta tesis. ABSTRACT The main goal of this research thesis is to shed light on a specific documentary record: patents presented in Spain, regarding a specific theme: bicycles and cycling, within a given period: 1826-1929. This record is organized for the ulterior use by the scientific community. In order to carry out this goal, the mentioned patents have been identified and systematized, and analyzed for frequency in order to infer the incidence of its invention in the period under consideration. This has brought to light some information on the inventors which are, after all, the creators in the technological development of that field. Their bibliographical information: origin, type of inventor (company or individual), gender, collaboration behavior and profession. Finally, the type of inventions has been studied, showing the sectors in which inventions are produced, whether these were transferred to practice, and other key information like the incremental nature of their invention, their possible consideration as ‘rare or curious invention’, and their coexistence with a registered trademark. This thesis is organized with an initial introduction, after which a section outlines the theoretical framework for the research along two axes: first the context of the patent documents, their relation with innovation and their usefulness as information sources; second, the invention of cycling and the development phases of bicycles. In the methodological section the sources and methodology are explained and reasoned, followed by the research design: 1-determination of the data universe, 2-consultation at the historical archive of the OEPM (National Patent Office), 3-design and creation of a database, 3-analysis of the files and image catchment, 5-treatment and analysis of data, 6-browsing of source information for foreign patents, and 7-consultation of the trademark information at the OEPM. Chapter 4 is dedicated to research itself, in three main sections. The first one has the quantification of the patent total in tables and the analysis of specific overall chronological aspects of the invention, and some comparisons with the results obtained in other research. The second section is centered on the studies of patent requests and inventors. Some data extracted from the files has been systematized: geographical origin, adscriptions as companies or individuals, and their collaboration data, ending with a sub-section on women’s invention, which we consider an interesting research line. The third section, the biggest one of them all, is dedicated to the description and analysis of the data referred to the inventions themselves, because it is the application of the inventions which constitutes the technological development of the bicycle, and therefore its historical and social evolution. It is also structured in various sub-sections. The first one is the longest one, with information regarding the thematic typology of the inventions: functions and bicycle components which are innovated. The other ensuing subsections study patents which were actually incorporated and used, incremental inventions, curious inventions and patents with possible associated trademarks. Finally, the study conclusions, the establishment of lines of potential further research, the references used, and the annexes which culminate the thesis exposition.

Project based learning activities as a means of adapting conventional curricula to the demands of the 21st century aeronautical engineer: The design and building of the EYEFLY 1.

In this paper we report the process of designing and building the EYEFLY 1, a real UAS platform which has just performed its maiden flight. For the development of this aircraft, 30 groups of students from successive years at the Escuela Universitaria de Ingeniería Técnica Aeronáutica (EUITA) of the Universidad Politécnica de Madrid (UPM) carried out their compulsory End of Degree Project as a coordinated Project Based learning activity. Our conclusions clearly indicate that Project Based Learning activities can provide a valid complement to more conventional, theoretically-based, teaching methods. The combination of both approaches will allow us to maintain traditional but well-tested methods for providing our students with a sound knowledge of fundamental engineering disciplines and, at the same time, to introduce our students to exciting and relevant engineering situations and sceneries where social and business skills, such as communication skills, team-working or decision-taking, can be put into practice.

An integrated framework for office information systems design and management

Information Technologies are complex and this is true even in the smallest piece of equipment. But this kind of complexity is nothing comparejwith the one that arises when this technology interact with society. Office Automation has been traditionally considered as a technical field but there is no way to find solutions from a technical point of view when the problems are primarily social in their origin. Technology management has to change its focus from a pure technical perspective to a sociotechnical point of view. To facilitate this change, we propose a model that allows a better understanding between the managerial and the technical world, offering a coherent, complete and integrated perspective of both. The base for this model is an unfolding of the complexity found in information Technologies and a matching of these complexities with several levels considered within the Office, Office Automation and Human Factors dimensions. Each one of these domains is studied trough a set of distinctions that create a new and powerful understanding of its reality. Using this model we build up a map of Office Automation to be use^not only by managers but also by technicians because the primaty advantage of such a framework is that it allows a comprehensive evaluation of technology without requhing extensive technical knowledge. Thus, the model can be seen as principle for design and diagnosis of Office Automation and as a common reference for managers and specialist avoiding the severe limitations arising from the language used by the last

Blended learning in the design of collective protections in building works

The design of collective protections of construction works is a topic that is integrated within one of the MBTI subjects. This paper presents an experience for teaching the design of collective protection in building works. Teaching has been done in a bended way. This subject is taught as part of the content of a wider subject included in the Master "Building Technological Innovation" (MBTI) of the Universidad Politécnica de Madrid (UPM). This Master's degree is a postgraduate of research nature. Graduating in MBTI implies that students are in a position to begin their PhD thesis. At this stage, often students are not able to follow the rigour established by the schedule of classes. For this reason it is interesting that part of the teaching is developed in a non-classroom based way.

Design of in-building wireless networks deployments using evolutionary algorithms

In this article, a novel approach to deal with the design of in-building wireless networks deployments is proposed. This approach known as MOQZEA (Multiobjective Quality Zone Based Evolutionary Algorithm) is a hybr id evolutionary algorithm adapted to use a novel fitness function, based on the definition of quality zones for the different objective functions considered. This approach is conceived to solve wireless network design problems without previous information of the required number of transmitters, considering simultaneously a high number of objective functions and optimizing multiple configuration parameters of the transmitters.

Simplified serviceability design of jointless structures. Experimental verification and application to typical bridge and building structures

In this article an experimental campaign aimed at validating a previously published simplified serviceability design method of the columns of long jointless structures is presented. The proposed method is also extended to include tension stiffening effects which proved to be significant in structures with small amount of reinforcement subjected to small axial loading. This extension allows significant improvement of predictions for this type of element. The campaign involved columns with different reinforcement and squashing load ratios, given that these parameters had been identified as crucial when designing columns subjected to imposed displacements. Experimental results are presented and discussed, with particular regard to cracking behaviour and structural stiffness. Considerations on tension stiffening effects are also made. Finally, the application of the method to typical bridge and building cases is presented, showing the feasibility of jointless construction, and the limits which should be respected.

Building memristor applications: from device model to circuit design

Since the memristor was first built in 2008 at HP Labs, no end of devices and models have been presented. Also, new applications appear frequently. However, the integration of the device at the circuit level is not straightforward, because available models are still immature and/or suppose high computational loads, making their simulation long and cumbersome. This study assists circuit/systems designers in the integration of memristors in their applications, while aiding model developers in the validation of their proposals. We introduce the use of a memristor application framework to support the work of both the model developer and the circuit designer. First, the framework includes a library with the best-known memristor models, being easily extensible with upcoming models. Systematic modifications have been applied to these models to provide better convergence and significant simulations speedups. Second, a quick device simulator allows the study of the response of the models under different scenarios, helping the designer with the stimuli and operation time selection. Third, fine tuning of the device including parameters variations and threshold determination is also supported. Finally, SPICE/Spectre subcircuit generation is provided to ease the integration of the devices in application circuits. The framework provides the designer with total control overconvergence, computational load, and the evolution of system variables, overcoming usual problems in the integration of memristive devices.
