A metodologia utilizada foi a pesquisa bibliográfica, mas principalmente o estudo do código de ética, e o entendimento de cada um dos seus artigos, levando em consideração especial os que mais afetam o dia-a-dia do profissional. Nos dias atuais, as pessoas que atuam no mercado de trabalho, ao ouvir sobre leis e direito, se voltam mais a leis criminais ou infrações financeiras, esquecendo-se da ética. O entendimento desse aspecto da lei é de fundamental importância, pois dita como deve ser o comportamento do engenheiro no seu ambiente de trabalho, e o seu relacionamento com os demais colegas e clientes. Outro fator importante do código de ética é a preocupação com o meio ambiente, levando o profissional a pensar em como desenvolver o seu trabalho de forma sustentável, garantindo assim, um futuro melhor para as próximas gerações.

The pinch point step is critical in the aluminum can recycling process. This process is fundamental to help an action that reduces pollution and waste production and that causes a cycle in the production process. The work aims to streamline the press step, which is performed manually by collectors, creating an efficient system through the use of a Programmable Logic Controller (PLC) and pneumatic actuators making it possible to reduce the volume of metal cans to compact storage. pneumatic pistons are used for the packing of tins and has a conveyor belt used to carry the cans to the pinch point location, which would be deposited in the storage container. All control is done through PLC. This work stands out for having a metallic material separation system and nonmetallic, through sensors that tells the controller, responsible for taking decisions. The results were satisfactory because the correct selectivity.

The prototype had its engine controlled by an H bridge switching through PWM port an embedded system. All communication is done via RF modules. The final design was composed of the prototype and a glove that had the transmitter module, which sent the motion information to the car, and the receiving plate, which was responsible for the PWM signal controlling the engine prototype. Its speed was controlled by the wearer's wrist angulation; as the clock approached 90, the car reached maximum speed and the same move forward and backward. In addition to the control system, the car was also equipped with an ultrasound sensor to prevent head-on collisions. The control system showed satisfactory efficiency relative speed and the distance that the car was controlled, and avoid collision obstacles.

O trabalho é apresentado mostrando alguns tipos de motores elétricos de corrente contínua (CC) e suas principais aplicações. INTRODUÇÃO " Motores elétricos são uma parte importantíssima do processo produtivo industrial, não só no Brasil, como no mundo. Base de uma infinidade de equipamentos e facilidades como gerador de força motriz, o parque de motores elétricos é responsável pelo consumo de um terço de toda a energia ofertada no país " [Editado] (Garcia, 2003). O motor elétrico é o responsável por converter a energia elétrica que chega em nossas casas, empresas, indústrias, etc. em uma forma de energia mecânica capaz de gerar trabalho, onde será transmitido para mover equipamentos ou substituir trabalho humano. Hoje em dia, o motor elétrico faz parte cotidiano da sociedade estando nos mais diversos equipamentos, desde os mais simples, como os liquidificadores, até os maiores, como elevadores, etc. E é também parte fundamental da automação industrial.

The application of a series resonant converter in a SST allows improvement of its efficiency, through soft switching of the power switches. The present paper proposes a bidirectional topology capable of receiving an AC voltage in its input, and delivers the same AC voltage on its output through a series resonant converter and a push-pull AC-AC converter, with all switches operating with soft switching. The converter has three different switching elements and is capable of adjusting the output voltage level by changing the switching frequency. In this paper, the description of the converter's operation and simulation results are presented. A prototype is being built to be tested in laboratory.

O protótipo teve o seu motor controlado por uma ponte H, chaveada através de portas PWM de um sistema embarcado. Toda a comunicação foi feita através de módulos RF. O projeto final foi composto pelo protótipo e por uma luva, que possuía o módulo transmissor, que enviava as informações de movimento para o carro, e a placa receptora, que era responsável pelo sinal PWM que controlava o motor do protótipo. A sua velocidade era controlada através da angulação do pulso do portador; à medida que o pulso se aproximava de 90º, o carro atingia velocidade máxima, podendo o mesmo se movimentar para frente e para trás. Além de ter sistema de controle, o carro também foi equipado com sensor ultrassom para evitar colisões frontais. O sistema de controle mostrou eficiência satisfatória em relação a velocidade e a distância em que o carro era controlado, e ao evitar colisão em obstáculos.
