To solve the writing and reading operation conflict to RAM in LED/LCD display control system, a new RAM operation conflict arbiter IC was proposed. Comparing the traditional dual ports RAM, the IC has the advantages of low-cost and high stability. By analyzing the working principle and structure design, the IC was designed in pure digital way with Verilog HDL, and passed the simulation verify. Finally the IC was realized by Alter FPGA chip and passed the actual test.

In stamping production the traditional manual feeding and pick-up manner can lead to potential safety problem. The automatic feeding and automatic pick-up device can ensure the production safety and ease workers’ labor intensity. A kind of automatic feeding and automatic pick-up device and its control system are designed. The configuration, function and working principle of the mechanism were described. Hydraulic system was taken as power supply. Siemens S7-200 was adapted as the center of control system, Hall-effect switch sensor CS1020 was used to detect the position of components. Control theory was studied and programmed. The device described in this paper can realize stamping automatic. Adjusting the position and number of sensors can realize the feeding and pick-up automation of all kind of workpiece, make the system has flexibility and suit the change of production.

Maritime transportation has been a cost-effective option among other transport modes. Meanwhile, this demand has been increasing day by day because of the expanding global economy. The ships are one of the most important transport and trade vehicles in the world; 90% of the world trade is carried out by maritime transport, and this sector plays a crucial role in climate change and global warming because it is one of the key sectors leading to emissions of carbon dioxide, the main greenhouse gas (GHG). In other sectors that lead to CO2 emissions, i.e., energy production, manufacturing industry, and heating in residences, energy efficiency has been improved and emissions have been reduced significantly. However, there has been no net reduction in the transport sector; total CO2 emissions have also increased because of the continuous increase in freight and passenger traffic, although efficiency has increased. Increasing the energy efficiency of a ship allows for fuel consumption reduction and GHG emissions. In this study, the energy system of a chemical tanker ship was analyzed and then modeled by using the long-range energy alternatives planning system, a widely used platform for energy policy analysis and climate change mitigation assessment, including a comprehensive energy flow diagram, namely, reference energy system. A base scenario was developed, and the ship’s energy system was convenient to be analyzed and evaluated in terms of technical, economic, and environmental aspects, including low-emission development strategies, to comply with marine engine regulations of the International Maritime Organization.

This paper introduces the working principle of power system on tracked vehicles. Tracked vehicles with high pressure air or pulling the battery starts, due to the main power supply system power supply, can't fight. Through an analysis on the failure of electricity generation of the main power system, a tachometer sensor is designed and used as main power providing excitation and causing an electric potential difference, which realizes passive power supply after non-battery starting.

Emerging commercialised anthropomorphic hand prostheses have two main categories: expensive ones with remarkable functionality afforded by complex control systems, and inherently inexpensive ones with basic gripper-like aptitudes that do not fully fulfil the basic physical and emotional requirements of upper-limb amputees or individuals with upper limb congenital defects. This paper aims to establish a middle ground between these two commercial alternatives by realizing a low-cost and highly functional robotic hand. All five digits of the proposed robotic hand are controlled by a single DC motor. This desirable feature is afforded by the implementation of under-actuation. The under-actuation in the fingers is achieved through four-bar linkages coupling with cartwheel flexure joints, which leads to not only shape adaptation, i.e., the ability to naturally adapt to the form of the article being grasped without the aid of intricate control systems, but also low cost due to the possibility of monolithic fabrication (e.g. 3D printing) and ease of control. The under-actuation in the palm system is implemented via the use of a differential pulley mechanism embedded thereof, which furthermore results in low cost by reducing the number of actuators and simplifying the control system. A simple and easy-to-use control system based on voice commands through a smart phone was also developed. It is envisaged that the proposed design can also be applied in various engineering environments to meet adaptability/under-actuation needs.

In order to satisfy the great demands of remote, real-time and flexible image acquisition in monitoring system, a solution to pan-tilt control system in remote image monitoring system is presented, which is based on ARM Cortex-M3 micro-controller and radio communication. And then, the hardware and software design is discussed in detail. Finally, the result shows that the pan-tilt control system provides many advantages such as remote and flexible control, high precision and low cost. So it has a huge market with big potential and wide prospect.

As a new intelligent material, IPMC (Ionic polymer-metal composite) can be driven under low voltage with large deformation, and has been widely used in biomedical and robotic systems. Traditional IPMC testing system is bulky, high cost, and inconvenient to use. In order to achieve the portability and convenience of the IPMC testing system, a small and low-cost IPMC tester was designed. The power supply and control system of the tester were integrated into an IPMC electrode clamp. The main research work included control system circuit design, electrode clamp and overall exterior design. The displacement measurement results showed that the design for the IPMC tester was correct and feasible.

There is a well-known water crisis throughout the world. This crisis has serious health implications and is especially severe in developing countries. Even though water is available in many locations, it is often polluted by microorganisms. We describe a system that is made of copper screen or foil in a closed container, either polyethylene or glass bottles that are used for killing microorganisms in batches of water of volume approximately 800 ml. In this system, a volume of microbe contaminated water is exposed to the metal in a container with a head space of air so that a water–air–metal interface is visible. The bottle is capped and agitated, usually by shaking, for 20–30 minutes. Other means of agitation also worked, such as walking with the container as if it were a canteen. By this process a sufficient number of microbes are eradicated and the water is made potable. A particulate filter made of cloth on top of a small gage screen or the like is used to remove large particulates; however, the system works well in its absence.

The rapid increase in wireless technology has enormously increased wireless control of lighting system in residential, commercial, and industrial settings of many countries across the world. However, this system lacks troubleshooting interface, making it very difficult for the identification of faults in the lighting system. This paper therefore seeks to improve on the wireless lighting system by incorporating into the system two types of sensors such as the current sensor and light dependent resistance (LDR). The current sensor is functioned to determine fault in power supply, whilst the LDR determines fault due to damage in the AC lamp. The proposed system was first simulated with Proteus software to observe the set objectives. A successful simulation resulted in the implementation of the system. The results discussed prove that incorporating wireless technology with current sensor and LDR will make troubleshooting easy and effective when the need arises.
