This paper presents a system dedicated to monitoring the heart activity parameters using Electrocardiography (ECG) mobile devices and a Wearable Heart Monitoring Inductive Sensor (WHMIS) that represents a new method and device, developed by us as an experimental model, used to assess the mechanical activity of the hearth using inductive sensors that are inserted in the fabric of the clothes. Only one inductive sensor is incorporated in the clothes in front of the apex area and it is able to assess the cardiorespiratory activity while in the prior of the art are presented methods that predict sensors arrays which are distributed in more places of the body. The parameters that are assessed are heart data-rate and respiration. The results are considered preliminary in order to prove the feasibility of this method. The main goal of the study is to extract the respiration and the data-rate parameters from the same output signal generated by the inductance-to-number convertor using a proper algorithm. The conceived device is meant to be part of the “wear and forget” equipment dedicated to monitoring the vital signs continuously.

In this paper we aim to present an evolution of the development of robotic end effectors with applications in fruit and vegetable harvesting but without exhaustively covering all technical solutions. This study is focused on robotic final effectors dedicated to harvesting fruits that have reached an advanced stage of development for apples, tomatoes, sweet peppers and cucumbers. The performances of these final effectors (harvesting speed, success rate, costs, etc.) are compared with the performances of human operators and we could say that so far the robots fail to reach the efficiency of human operators in the harvesting processes. The success rate is below 90% and the harvest times are longer than 10 seconds and this means a low efficiency. Although the level of commercial robots for fruit harvesting has not been reached, technological developments indicate an improvement in the performance of this category of robots, an increasing number of research projects are focused on tomato and apple harvesting technologies.

Operating in a dynamic and competitive global market, railway companies have realized many years ago that better management of their logistical operations will enhance their strategic positions on the market. The financial component of daily operations is of utmost importance these days and many companies concluded that maximizing the profit relies on the integration of logistical activities with better income management. This paper presents a system consisting of three components: Ferodata BOX, Ferodata MOBILE, and Ferodata SYS, used to transmit to a web-server the status and operating information of an electric or diesel train. Train information includes data from locomotives, wagons, train driver, route, direction, fuel or electric consumption, speed, etc. All this information is processed in real-time and can be viewed in the web-server application. Additionally, the web-server application could manage and report details that are coming from the wagons, such as valuable information regarding the bogie wear, the identification of the wagons attached to a gasket, and identification the situations in which a wagon or group of wagons comes off the gasket configuration. All information about the status of trains is available on-line and at any moment the person responsible for management can use these data in their work.

This paper presents a new concept of the robots dedicated to small farming activities. A walking robot is remote controlled in order to perform agricultural operations in small farms or peasant household. The robot should perform all operations during crop development respectively tilling seeding, fertilization, harvesting, etc. The robot structure is conceived in order to achieve low energy consumption criteria by gravitational decupling and static gait. The power of the robot is calculated robot power is calculated by reference to the power of a man or a horse. The purpose of this work is to approach some aspects of a robot according with the requirements of work environments: energy consumption, influence to the environment, the proper locomotion method, etc.
