Due to the popularity and need to learn sign language, there are tools that help in this type of communication. In Brazil, for example, the government offers professional Sign Language to assist communities, however, if think the hypothesis that people live in places difficult access, there is a difficult in movement of professionals to such places, besides bringing government overspending. Thus, a tool that simulates the movements of professional, fully exploiting the technological resources (cost-benefit) to enrich and provide a tool for communities, it becomes possible order to fill this gap. The system provides resources for editing movements, and these, later, are retrieved by tool for the visualization and representation of signals in a Virtual Environment. The resources used, provide two unconventional devices for tracking body, the Wiimote controllers and P5 glove.

Automated Production Systems Development involves aspects concerning the integration of technological components that exist on the market, such as: Programmable Logic Controllers (PLC), robot manipulators, various sensors and actuators, image processing systems, communication networks and collaborative supervisory systems; all integrated into a single application. This paper proposes an automated platform for experimentation, implemented through typical architecture for Automated Production Systems, which integrates the technological components described above, in order to allow researchers and students to carry out practical laboratory activities. These activities will complement the theoretical knowledge acquired by the students in the classroom, thus improving their training and professional skills. A platform designed using this generic structure will allow users to work within an educational environment that reflects most aspects found in Industrial Automated Manufacturing Systems, such as technology integration, communication networks, process control and production management. In addition, this platform offers the possibility complete automated process of control and supervision via remote connection through the internet (WebLab), enabling knowledge sharing between different teaching and research groups.

Hymenoptera é uma das maiores ordens de insetos, com mais de 130 mil espécies descritas. Dentre as principais famílias destacam-se: Formicidae, Apidae e Vespidae, sendo que a última inclui a grande diversidade de vespas sociais presentes no Brasil. Este grupo tem grande importância no controle biológico de outras populações, como predadores ou controladores de pragas agrícolas, além de serem visitantes florais e polinizadores ocasionais. Sendo assim, o presente estudo consiste em um inventário das vespas sociais da Floresta Estadual Edmundo Navarro de Andrade (FEENA) em Rio Claro, SP, que possibilitou a comparação entre diferentes métodos de coleta empregados na captura de vespas sociais (coleta ativa e armadilhas atrativas em diferentes estratos na vegetação) e a comparação da fauna atual com um inventário realizado a mais de 30 anos na mesma localidade. Os dados foram coletados em diferentes estratos da vegetação utilizando armadilhas de garrafa PET contendo líquido atrativo (uma próximo ao solo, outra a 1,5 m de altura e a outra acima de 3 m na copa das árvores), e através de técnicas de coletas ativa com auxílio de redes entomológicas. Foram realizadas quatro coletas no decorrer de um ano, uma em cada estação. A riqueza das espécies do atual inventário foi comparada com a de Rodrigues & Machado (1982) e observou-se uma diminuição do número de espécies ao longo dos anos, de 32 para 21, sendo que 17 espécies foram amostradas em ambos os inventários. Dentre as armadilhas atrativas, houve diferença entre os estratos, sendo que as armadilhas de dossel mostraram ser de grande importância, pois capturaram 41,8% dos indivíduos e ainda apresentaram quatro espécies capturadas exclusivamente neste estrato. A técnica de coleta ativa com redes entomológicas também foi relevante, sendo responsável pela coleta de 93,75% dos indivíduos da tribo Mischocyttarini

This paper presents a Project of an automatic feeder for pets using an Arduino Uno as the control center. Through studies on this driver was possible to create a device with an interface capable to receiving user input and then use it to activate the feeder in the defined hours. For mounting equipment were used steps motors, sensors, keyboard and display, which work together to instrument operation. The project goal was reached and the prototype developed indicating that the Arduino can be used for various applications that can simplify daily tasks

This work studies and develops a machine automation for tyre truing. It is discussed industry development, industrial processes automation, tyre-recycling process, advantages of tyre reuse for preservation of the environment and probable gains from the automation of part of the tyre-recycling process. In this text, it is detailed the work done to configure, program and optimize the truing process through automation components as CNC, PLC and drives. Tests and simulations are performed to determine the payback necessary period in productivity and profit gains

This monograph presents the main objective of analyzing the redundancy protection systems of protection for redundancy and block of energies against accident in presses and rotating equipment. After understanding two specific goals, on this case, show the systems of protection against accidents in rotating equipments, presses and similar; and discuss the vulnerabilities of current systems of protection against accidents in presses and similar, we will propose a system of autonomous redundancy of Programmable Logic Controller (PLC) operating simultaneously taking online in the event of failure of one of the two. The methodology was worked through a revision of a variety of bibliography, and interpretation of national and international standards as well as access to research on systems, practices used in industrial and companies supplying products and of companies and energy blockages solutions
