In industries loading and unloading of heavy loads manually is one of the most important task which turns out to be quite difficult, time-consuming and risky for humans. This paper illustrates the mechanical design of the industry based automated robot which include: Ackerman Steering Mechanism and Differential Mechanism. Ackerman Steering allows front two wheels to turn left and right in the track without going out of the track. Differential has been mounted with two back wheels and a DC motor has been used with its controller to start motion of the robot. The autonomous robot is designed to start its movement from a starting position where goods are loaded on it, then follow a path of white line drawn on black surface and unload goods by itself after reaching a destination place. Digital Line Following sensor has been mounted in front of the robot so that the sensor can detect path by emitting and receiving signals allowing it to move in the pre-defined track having left and right turns while carrying goods from starting position to the destination. The main objective is to load and unload heavy goods that has been achieved by two large linear actuators for producing required torque and force necessary to unload heavy loads up to 150kg sideways to the ground safely. Besides, the robot has been built up having the ability to avoid collision with any obstacles that come in its way. Building an industrial robot with moderate speed, good efficiency for loading and unloading purpose within a short time to ease human suffering has been the main focus of this paper.

On a ship's bridge, the deck officer who has the duty of navigating and keeping watch is known as the officer of the watch (OOW). Many of the causes of accidents relate not only to the OOW's knowledge and capability, but to his or her cognitive process. The cognitive reliability and error analysis method (CREAM) is a technique for analyzing human reliability. The CREAM organizes interactions between humans and the environment by using the human-technology-organization triad. The CREAM defines common performance conditions (CPCs), the dependencies between them, and the links between antecedents and consequences, thus clarifying the background factors that affect human performance. This method has mainly been used in the nuclear industry, but since conditions change across domains, CPCs apply differently to other domains. Based on the considerations above, we have adapted CPCs to maritime collision accidents, and administered a questionnaire to OOWs for the purpose of quantifying the dependency and priority of CPCs. This paper introduces the support for the retrospective analysis of marine accidents.

Medial patello-femoral ligament (MPFL) reconstruction surgery requires tension and length information of the graft for proper function. Current technique fixes the graft with subjective feeling of the tension and length. Therefore, the technique has not been established well due to lack of quantitative information. To measure the tension and length change at the same time, we manufactured a tension and length measurement system with a tension sensor and a rotary encoder. In the experiment, we calibrated an experiment of the tension sensor with the stress testing machine. We measured force change when the tension sensor was pulled in the horizontal direction by using the load cell tension sensor in the calibration experiments. In the tension measurement experiment, we measured the changes in tension and length of the suture which was attached to the position of MPFL during flexion and extension by using imitation femur and patella. The change of the length of the suture was measured with a rotary encoder. Consequently, the proposed system could measure tension and length information of MPFL simultaneously.

In this paper, we present a novel method for a hardware-based search in the rule tables of software defined network (SDN) switches. We describe the design features of modern SDNs based on the open standard OpenFlow, and highlight the main problems of modern OpenFlow switches. We then propose a new approach for a flow table search based on field-programmable gate arrays (FPGAs). The proposed method allows searching by means of a mask in all bits of the header of incoming packages and therefore to expand the usability of SDNs.

The elimination of the stand-by power consumption of the electronic products is very important for not only the family budget but also the earth environment. To completely eliminate it, we have to remove each power cable of the electronic products from the power strip. Since this job is troublesome for the persons, especially elderly people, they tend to cease to do it as daily action. We have proposed a remotely controlled power switch that can make the standby power consumption of the electronic product and itself completely zero. The plugging and unplugging the power cable from a power strip is replaced to the operations of the infrared remote controller. The electronic product with our proposal is operated by the same remote controller. That is, all people can handle the elimination of the standby power and the operations for the electronic product by the single remote controller easily. However, to widely disseminate this proposal, the operable distance to eliminate the stand-by power consumption and to start up the electronic product has to be comparable to the conventional distance to operate the electronic product. This paper proposes an extending method of the operable distance for the IR remote controlled power switch about eliminating the stand-by power and starting up the electronic product. This method has the two-stage switching structure to turn on the main power by using a little energy harvesting gained from the infrared light irradiated by the remote controller. The experimental result shows the proposed method can actually generate enough power to turn on the electronic product with longer distance than the conventional one.

Currently in care facilities, a fall preventive movement sensor is often used to prevent falls of care receivers during the night.. But the current sensors are usually designed to detect the motion of care receivers' getting out of bed. Therefore, there are cases where the care receiver has already fallen from the bed by the time the sensor reacted to the movement. It is a common knowledge that a person frequently changes position while sleeping. In this research, we focus on the frequency of sleeping position changes, and aim to realize a method for precise prediction of care receivers' attempt to get out of bed sufficiently before the actual action. We employed the automatic classification method of sleeping position in the pressure-sensitive sensor, with consideration to privacy of the research subjects, and identified nine types of sleeping position that are common, with 77.1% of accuracy. This result is reported in this paper.

Recently, unmanned smart devices have become popular in various fields from the military to civil use. Flight in complex urban areas requires high-level autonomous flying techniques to ensure the safety of people. In addition, UAVs can encounter critical circumstances when flying because of inevitable obstacles, component malfunction, or faulty systems. These factors can force emergency landing on suitable spots. This paper proposes an emergency landing procedure that uses pre-selected available landing spots from satellite images, and navigates UAVs to such spots in an emergency. Searching suitable landing spots using a camera in an emergency is time-consuming. This paper also proposes a simple method that searches for landing spots in satellite images using proper shapes and areas. By applying this method, our results estimate that appropriate landing spots can be searched correctly.

Cognitive radio (CR) solves the spectrum insufficiency crisis by intelligently permitting secondary, or unlicensed, users entrance to the primary, licensed, users' frequency bands. Here considered a network of multiple primary users (PU) and multiple secondary users (SU). The objective of the SUs is to get entrance to orthogonal channels every one in use by one PU. Only one SU is permitted to coexist with a specified PU. In this paper proposed a distributed harmonizing algorithm to couple the network users where a Stackelberg game model is assumed for the relations between the coupled PU and SU. The preferred SU is agreed access in switch for monetary reward to the PU. The PU also amplifies its power to assemble its velocity obligation regardless of the SU's existence. The PU search for optimizing the intervention cost it suggests to a certain SU and the power allowance to sustain communication. The algorithm is exposed to execute secure to an optimal central controller, albeit at a condensed computational difficulty. The SU, alternatively, look for optimize its power demand so as to exploit its service. It is proven that this algorithm grants a sole steady harmonizing. Numerical results specify the supremacy of the proposed algorithm to a casual coupling of the users. Moreover, the algorithm is exposed to execute secure to an optimal central controller, albeit at a condensed computational intricacy.
